The Silent Inflammation That Afflicts 3 Out of 4 Americans

February 6, 2015 By Sherri

carotenoids as natural astaxanthin

Story at-a-glance+

By Dr. Mercola – July 12, 2011

Scientists long ago discovered that a class of naturally occurring pigments called carotenoids held powerful antioxidant properties that are crucial for your health.

Carotenoids are the compounds in your foods that give you that vibrant cornucopia of color—from green grasses to red beets, to the spectacular yellows and oranges of bell peppers—as well as all of the beautiful flowers in your garden.

There are more than 700 naturally occurring carotenoids, but most people are familiar with only a few. Right now, you probably have about ten different carotenoids circulating through your bloodstream.

Only recently has one particular carotenoid jumped to the front of the line in terms of its status as a “supernutrient,” becoming the focus of a large and growing number of peer-reviewed scientific studies.

This carotenoid is called natural astaxanthin.

Synthetic (laboratory-made) astaxanthin is now commonly used worldwide to supplement fish feed lots in order to help them obtain the desired pinkish to orange-red color. You really should avoid synthetic astaxanthin because it’s made from petrochemicals.

Not only does natural astaxanthin carry potent antioxidant abilities, but as it turns out, it is also a powerful anti-inflammatory, which will be the focus of this article. Other carotenoids are easily obtainable through a good diet rich in fresh organic produce. However, this powerful carotenoid is harder to come by.

Astaxanthin Is in a League of Its Own

Astaxanthin is produced only by the microalgae Haematococcus pluvialis when its water supply dries up, forcing it to protect itself from ultraviolet radiation. It’s the algae’s survival mechanism—Astaxanthin serves as a “force field” to protect the algae from lack of nutrition and/or intense sunlight.

Astaxanthin is now thought to be the most powerful antioxidant found in nature.

There are only two main sources of astaxanthin—the microalgae that produce it, and the sea creatures that consume the algae (such as salmon, shellfish, and krill).Astaxanthin is now thought to be the most powerful antioxidant found in nature.

This pigment is the most commonly occurring red carotenoid in marine and aquatic animals and is what gives salmon their characteristic pink color. Astaxanthin is far more powerful than beta-carotene, alpha-tocopherol, lycopene and lutein, other members of its chemical family. It exhibits VERY STRONG free radical scavenging activity and helps protect your cells, organs, and body tissues from oxidative damage and inflammation.

What Makes Astaxanthin Special?

There are many properties that make this carotenoid unique. Here are the main differences:

  • Astaxanthin is by far the most powerful carotenoid antioxidant when it comes to free radical scavenging: astaxanthin is 65 times more powerful than vitamin C,1 54 times more powerful than beta-carotene, and 14 times more powerful than vitamin E.
  • Astaxanthin is far more effective than other carotenoids at “singlet oxygen quenching,” which is a particular type of oxidation. The damaging effects of sunlight and various organic materials are caused by this less-stable form of oxygen. Astaxanthin is 550 times more powerful than vitamin Eand 11 times more powerful than beta-carotene at neutralizing singlet oxygen.
  • Astaxanthin crosses the blood-brain barrier AND the blood-retinal barrier (beta carotene and lycopene do not), which brings antioxidant and anti-inflammatory protection to your eyes, brain and central nervous system and reducing your risk for cataracts, macular degeneration, blindness, dementia, and Alzheimer’s disease.
  • Astaxanthin is soluble in lipids, so it incorporates into cell membranes.
  • It’s a potent UVB absorber and reduces DNA damage.
  • It’s a very potent natural anti-inflammatory.

And how about some more great news?

There have been no adverse reactions found for people taking astaxanthin. Before I go into how astaxanthin works as an anti-inflammatory, let’s review what inflammation is and how it can cause devastating disease.

What You Need to Know About Inflammation

Inflammation is a necessary and important biological process that allows you to survive. It’s your body’s response to fighting infection and repairing damaged tissues—in other words, it’s part of your natural healing process. If you didn’t have inflammation, you’d never heal from any infection or injury.

When a foreign bacterium or virus enters your body, your inflammatory body kicks in to eliminate it. If you sprain your ankle, your inflammatory system activates to begin repairing damaged tissues.

There are five classic signs and symptoms of inflammation:

  1. Redness
  2. Pain
  3. Warmth
  4. Swelling
  5. Loss of function

Even sunburn is a sign of inflammation—when UV rays begin to damage your skin cells, the inflammatory “machine” turns on, making your skin red and warm. Mast cells are the key initiators of inflammation, activating potent “mediators.” The mediators attract white blood cells, and activate cells that produce additional mediators.

Mediators come in many forms, including:

  • Histamines
  • Tumor necrosis factor-alpha
  • Nitric oxide
  • Hydrogen peroxide
  • Interleukins
  • Prostaglandins (produced from arachidonic acid and the COX-1 and COX-2 enzymes)

Although having a red, swollen and painful sprained ankle is a clear sign you are experiencing inflammation, you may have an undercurrent of inflammation in your body and not even be aware. And silence can be deadly.

Chronic Inflammation: Silence Is Deadly

Inflammation comes and goes in your body as part of the normal healing process. However, prolonged inflammation can be devastating. Many people are experiencing ongoing, low-level inflammation without even knowing it—and this is a crucial factor behind chronic disease.

This systemic or “silent” inflammation is the evil twin of oxidation, and where you find one, you nearly always find the other. But this type of inflammation doesn’t cause you any pain—it lives “under the radar,” quietly lingering for years and even decades, where it silently injures your heart, brain, and immune system.

Left unchecked, systemic inflammation can lead to anything from asthma to rheumatoid arthritis to Alzheimer’s disease. In fact, the number of diseases linked to chronic inflammation is staggering:

  • Heart disease, atherosclerosis and stroke
  • Diabetes
  • Alzheimer’s disease
  • Parkinson’s disease
  • Multiple sclerosis
  • Rheumatoid arthritis
  • Ulcers, irritable bowel syndrome (IBS), and colon cancer
  • Allergies

There are many, many more. Unfortunately, Americans have the highest levels of silent inflammation in the world, with over 75 percent of people afflicted.

Why?

Two words: diet and lifestyle. Some of the largest contributors to chronic inflammation are smoking; a diet high in sugar, fried foods and trans fats; inadequate exercise; stress; and vitamin D deficiency. There are a couple of ways to measure how much inflammation is silently occurring in your body.

One blood test measures a substance called C-reactive protein (CRP), which might actually be a better predictor of your heart attack risk than lipids. Another test is called Sed Rate (or ESR for “erythrocyte sedimentation rate”), which is especially helpful in monitoring rheumatoid arthritis and other autoimmune diseases.

CRP is produced in your liver and coronary arteries, then released into your bloodstream when your body is fighting inflammation. In one study, natural astaxanthin was found to reduce CRP levels by 20 percent in just eight weeks. Another study found astaxanthin caused 43 percent of people with high CRP levels to drop into the average-risk range.

Clearly, this powerful agent has a remarkable ability to cool down the inflammatory process, thereby decreasing your body’s need to produce CRP.

By decreasing inflammation, astaxanthin can help prevent, and treat, a number of problems that result directly from inflammation, including rheumatoid arthritis, tennis elbow, carpal tunnel syndrome, and other repetitive stress injuries, which I will talk more about shortly.

Anti-Inflammatory Drugs Are Definitely NOT the Answer

Anti-inflammatories have earned a bad reputation. This is due to the fact that most of the compounds people commonly recognize as anti-inflammatories are DRUGS, rather than natural agents. Natural anti-inflammatories, on the other hand, can be very beneficial and lack the adverse side effects of anti-inflammatory drugs.

As a quick review, let’s review the truth about some anti-inflammatory drugs:

  • Aspirin can cause your stomach to bleed (acts on both COX-1 and COX-2)
  • Tylenol (acetaminophen) can damage your liver
  • Vioxx and Celebrex (non-steroidal anti-inflammatories, or NSAIDS) can cause heart problems (act strongly on COX-2 only)

In 1999, the New England Journal of Medicine stated that NSAIDS have caused as many deaths as AIDS. Vioxx alone has killed more than 60,000 people! I urge you to avoid these dangerous anti-inflammatory drugs since they have the potential to cause very serious side effects and even death. But astaxanthin is a different story and will not harm you.

Astaxanthin affects a wide range of mediators, but in a gentler, less concentrated manner and without the negative side effects. And it works for 4 out of 5 people. In one study,2 more than 80 percent of arthritis sufferers improved with astaxanthin.

Folks, that is four out of five people, that is impressive.

How Astaxanthin Tells Your Inflammation to ‘Chill’

A great deal of research has been done into how astaxanthin reduces inflammation. As is true for many antioxidants, its anti-inflammatory properties are related to its powerful antioxidant activity.

Astaxanthin suppresses a variety of inflammatory mediators—including tumor necrosis factor alpha, a major prostaglandin and a major interleukin, nitric oxide, COX-1 and COX-2 enzymes. It takes longer to produce effects than NSAIDS, but this means it doesn’t result in the dangerous side effects.

As G. Cole, UCLA Professor of Medicine and Neurology, reported to Newsweek Magazine in a Special Summer Issue in 2005 (pages 26-28):

“While anti-inflammatory drugs usually block a single target molecule and reduce its activity dramatically, natural anti-inflammatories gently tweak a broader range of inflammatory compounds. You’ll get greater safety and efficacy reducing five inflammatory mediators by 30 percent than by reducing one by 100 percent.”

So, what sorts of conditions can astaxanthin treat?

Astaxanthin May Help You Be an Athlete Extraordinaire or Weekend Warrior

The evidence is very positive for astaxanthin’s effects on a variety of inflammatory disorders. Let’s take a look at the human clinical studies related to four common inflammatory complaints: tennis elbow, carpal tunnel, rheumatoid arthritis, and exercise-related joint soreness.

    1. Tennis elbow (tendonitis): Caused by inflamed tendons, tennis elbow results in pain and decreased grip strength when gripping something with your hand.

A study by the Health Research and Studies Center involved giving tennis elbow sufferers an eight-week course of astaxanthin. The treatment group showed a 93 percent improvement in grip strength, as well as decreased pain.

    1. Carpal tunnel syndrome (CTS), aka “repetitive stress injury”: CTS is a debilitating disease of the wrist that manifests as numbness, pain, and even paralysis.

A study by the above group found eight weeks of astaxanthin supplementation resulted in significant pain reduction, both in terms of severity and duration, leaving researchers concluding that astaxanthin might be a viable alternative to surgery.

    1. Rheumatoid arthritis: RA is a painful and disfiguring autoimmune disorder.

After receiving astaxanthin for only eight weeks, RA sufferers showed a 35 percent improvement in pain levels, as well as a 40 percent improvement in their ability to perform daily activities. [Journal of the American College of Nutrition. 21(5):Oct, 2002.]

    1. Post-exercise joint soreness: Can astaxanthin be of benefit to you if you are healthy and have no disease or affliction?

In 2001, Dr. Andrew Fry of the University of Memphis studied the effects of astaxanthin on healthy people who trained with weights and who would typically experience exercise-induced joint soreness. He gave young male subjects astaxanthin for three weeks, while they performed strenuous workouts, and then evaluated them for knee pain.

The placebo group experienced post-training knee soreness, lasting up to 48 hours after their workouts. But the treatment group showed no increase whatsoever in knee joint soreness following workouts. [Fry, A. (2001) “Astaxanthin Clinical Trial for Delayed Onset Muscular Soreness.” Human Performance Laboratories, The University of Memphis, Report 1, August 16, 2001.]

So it appears that this amazing nutrient can help you, whether you are a top athlete or a weekend warrior, whether you have mild overuse symptoms or a major inflammatory illness—it truly seems to have benefits for anyone and everyone!

Make Sure Your Astaxanthin Is the Natural Variety from Marine Algae—NOT Synthetic

Some aquaculture companies are beginning to use natural astaxanthin instead of synthetic, even though it costs more, because it’s better for the health of the animals, and it’s far superior for pigmentation. Animals fed fish food with natural astaxanthin have higher survival rates, better growth rates, better immunity, fertility, and reproduction. Unfortunately, synthetic astaxanthin still dominates the farmed salmon industry worldwide.

If your salmon label does not read “wild” or “naturally colored,” you’re probably going to be eating a coloring agent somewhat closer to motor oil than antioxidant. Natural astaxanthin is more than 20 times more powerful as an antioxidant than synthetic astaxanthin.

Wild salmon are 400 percent higher in astaxanthin than farmed salmon, and 100 percent of their pigment is natural astaxanthin, rather than synthetic. Plus, wild salmon have much higher levels of omega-3 fatty acids than the farmed version.

But even if you are successful in purchasing genuine wild salmon, there is the problem with high levels of mercury and other unwanted toxins, not to mention the skyrocketing prices.

Final Recommendations

You may recognize the name astaxanthin because I have mentioned it in reference to krill oil, my favorite source of animal-based omega-3 fatty acids. One of the reasons I am such a fan of krill is that itnaturally contains astaxanthin. And our krill oil has the highest concentration of astaxanthin of any krill oil on the market today.

But, as high as it is, new research suggests you could enjoy even MORE benefits by further increasing your astaxanthin, even if you are already taking a krill oil supplement.

If you decide to give astaxanthin a try, I recommend with a dose of 8-10 mg per day. If you are on a krill oil supplement, take that into consideration; different krill products have different concentrations of astaxanthin, so check your label.

Top Anti-Inflammatory Foods, Herbs, and Spices

February 6, 2015 By Sherri

Story at-a-glance+

By Dr. Mercola – February 2, 2015

Herbs and cooking spices contain a wide variety of antioxidants, minerals and vitamins, and help maximize the nutrient density of your meals. Every time you flavor your meals with herbs or spices you are literally “upgrading” your food without adding a single calorie.

In fact, on a per gram fresh weight basis, herbs rank even higher in antioxidant activity than fruits and vegetables, which are known to be high in antioxidants. Many studies have also shown that most spices tend to have unique medicinal qualities.

In the featured study,1 researchers from three Universities devised an experiment to evaluate the “true world” benefits of herbs and spices, by feeding them to people in quantities that are typically consumed simply by spicing up your meals. As noted by Dr. Michael Greger MD, who produced the video above:2

“The researchers could have taken the easy route and just measured the change in antioxidant level in one’s bloodstream before and after consumption, but the assumption that the appearance of antioxidant activity in the blood is an indication of bioavailability has a weakness.

Maybe more gets absorbed than we think but doesn’t show up on antioxidant tests because it gets bound up to proteins or cells. So the researchers attempted to measure physiological changes in the blood.

They were interested in whether absorbed compounds would be able to protect white blood cells from an oxidative or inflammatory injury—whether herb and spice consumption would protect the strands of our DNA from breaking when attacked by free radicals.”

Four Spices That Pack a Powerful Anti-Inflammatory Punch

For one week, 10 to 12 subjects in each of 13 groups consumed a small amount of a particular spice each day. For example, those in the oregano group ate just half a teaspoon of oregano daily for seven days. Blood samples were drawn one hour prior to consumption, and at the very end of the experiment.

The participants’ blood was then analyzed for antioxidant capacity. The researchers also analyzed how well the blood could dampen an induced inflammatory response in white blood cells.

This was done by placing the participants’ blood onto white blood cells that had been damaged by oxidized cholesterol (commonly found in fried foods). Even at the “everyday” dosage amounts given, four spices were found to be significantly effective at quelling the inflammatory response:

  1. Cloves
  2. Ginger
  3. Rosemary
  4. Turmeric

As noted in the featured article: “[T]he results represents what might happen when cells in our body are exposed to the levels of spices that circulate in our bloodstream after normal daily consumption—not megadoses in some pill. Just the amount that makes our spaghetti sauce, pumpkin pie, or curry sauce taste good.”

Other Potent Anti-Inflammatory Spices

An earlier study published in the Journal of Medicinal Foods3 found a direct correlation between the antioxidant phenol content of spice and herb extracts and their ability to inhibit glycation and block the formation of AGE compounds (advanced glycation end products), making them potent preventers of heart disease and premature aging.

Here, cloves were ranked as the most potent of 24 common herbs and spices found in your spice rack. In all, the following were found to be the top 10 most potent anti-inflammatory herbs and spices:

  1. Cloves
  2. Cinnamon
  3. Jamaican allspice
  4. Apple pie spice mixture
  5. Oregano
  6. Pumpkin pie spice mixture
  7. Marjoram
  8. Sage
  9. Thyme
  10.  Gourmet Italian spice

Inflammation Is at the Heart of Most Chronic Diseases

It’s important to realize that chronic inflammation is the source of many if not most diseases, including cancer, obesity, and heart disease, which essentially makes it the leading cause of death in the US.

While inflammation is a perfectly normal and beneficial process that occurs when your body’s white blood cells and chemicals protect you from foreign invaders like bacteria and viruses, it leads to trouble when the inflammatory response gets out of hand. Your diet has a lot to do with this chain of events.

While among the most potent, ounce for ounce, herbs and spices are certainly not the only anti-inflammatory ingredients available. A number of foods are well-known for their anti-inflammatory properties, and making sure you’re eating a wide variety of them on a regular basis can go a long way toward preventing chronic illness.

Top Seven Anti-Inflammatory Foods

The following foods and nutrients deserve special mention for their ability to quell inflammatory responses in your body:

1.  Animal-based omega-3 fat Animal-based omega-3 fats—found in fatty fish like wild Alaskan salmon and fish- or krill oil—help fight inflammation throughout your body. It’s particularly important for brain health. Research published in the Scandinavian Journal of Gastroenterology4 in 2012 confirmed that dietary supplementation with krill oil effectively reduced inflammation and oxidative stress.
2.  Leafy greens Dark leafy greens such as kale, spinach, collard greens and Swiss chard contain powerful antioxidants, flavonoids, carotenoids, and vitamin C—all of which help protect against cellular damage. Ideally, opt for organic locally grown veggies that are in season, and consider eating a fair amount of them raw. Juicing is an excellent way to get more greens into your diet.
3.  Blueberries Blueberries rate very high in antioxidant capacity compared to other fruits and vegetables. They are also lower in sugar than many other fruits.
4.  Tea Matcha tea is the most nutrient-rich green tea and comes in the form of a stone-ground unfermented powder. The best Matcha comes from Japan and has up to 17 times the antioxidants of wild blueberries, and seven times more than dark chocolate.Tulsi is another tea loaded with anti-inflammatory antioxidants and other micronutrients that support immune function and heart health.
5.  Fermented vegetables and traditionally cultured foods Optimizing your gut flora is important for a well-functioning immune system, and helps ward off chronic inflammation. In fact, the majority of inflammatory diseases start in your gut, as the result of an imbalanced microbiome. Fermented foods such as kefir, natto, kimchee, miso, tempeh, pickles, sauerkraut, olives, and other fermented vegetables, will help ‘reseed’ your gut with beneficial bacteria.Fermented foods can also help your body rid itself of harmful toxins such as heavy metals andpesticides that promote inflammation.
6.  Shiitake mushrooms Shiitake mushrooms contain strong compounds with the natural ability to discourage inflammation, such as Ergothioneine, which inhibits oxidative stress.They also contain a number of unique nutrients that many do not get enough of in their diet. One is copper, which is one of the few metallic elements accompanied by amino and fatty acids that are essential to human health. Since your body can’t synthesize copper, your diet must supply it regularly. Copper deficiency can be a factor in the development of coronary heart disease.
7.  Garlic Garlic has been treasured for its medicinal properties for centuries. It’s also one of the most heavily researched plant foods around. Over 170 studies5 show it benefitting more than 150 different conditions. Garlic exerts its benefits on multiple levels, offering anti-bacterial, anti-viral, anti-fungal, and antioxidant properties.It’s thought that much of garlic’s therapeutic effect comes from its sulfur-containing compounds, such as allicin. Research6 has revealed that as allicin digests in your body it produces sulfenic acid, a compound that reacts faster with dangerous free radicals than any other known compound.

Your Diet Is Key for Reducing Chronic Inflammation

The running thread linking a wide variety of common health problems—from obesity and diabetes to heart disease and cancer—is chronic inflammation. The key to reducing chronic inflammation in your body starts with your diet, and being liberal in your use of high-quality herbs and spices is one simple way to boost the quality of your food. They’re an inexpensive “secret weapon” that just about everyone can take advantage of. Spicing up your meals is not enough, however, if processed foods comprise the bulk of your diet.

It’s important to realize that dietary components can either prevent or trigger inflammation from taking root in your body, and processed foods do the latter, courtesy of pro-inflammatory ingredients like high fructose corn syrup, soy, processed vegetable oils (trans fats), and other chemical additives. Besides adding anti-inflammatory foods to your diet, you’ll also want to avoid the following pro-inflammatory dietary culprits as much as possible:

  • Refined sugar, processed fructose, and grains. If your fasting insulin level is three or above, consider dramatically reducing or eliminating grains and sugars until you optimize your insulin level, as insulin resistance this is a primary driver of chronic inflammation. As a general guideline, I recommend restricting your total fructose intake to 25 grams per day. If you’re insulin or leptin resistant (have high blood pressure, high cholesterol, heart disease, or are overweight), consider cutting that down to 15 grams per day until your insulin/leptin resistance has normalized
  • Oxidized cholesterol (cholesterol that has gone rancid, such as that from overcooked, scrambled eggs)
  • Foods cooked at high temperatures, especially if cooked with vegetable oil (such as peanut, corn, and soy oil)
  • Trans fats

Replacing processed foods with whole, ideally organic foods will automatically address most of these factors, especially if you eat a large portion of your food raw. Equally important is making sure you’re regularly reseeding your gut with beneficial bacteria, as mentioned above. To help you get started on a healthier diet, I suggest following my free Optimized Nutrition Plan, which starts at the beginner phase and systematically guides you step-by-step to the advanced level.

How Avocado Can Help Improve Your Cholesterol, Heart, and Brain Health

January 23, 2015 By Sherri

Visit the Mercola Video Library

Story at-a-glance+

By Dr. Mercola

Avocados are an excellent source of heart-healthy monounsaturated fat that is easily burned for energy, while being low in fructose. Not surprisingly, improved weight management1,2 is one of the health benefits of avocado consumption, and its high-fat, low-sugar content is likely a key factor contributing to this effect.

Research3 has also found that avocados are helpful for regulating your blood sugar levels. This is an important benefit for most people, considering that one in four American are either diabetic or pre-diabetic.

According to the California Avocado Commission, a medium Hass avocado contains about 22.5 grams of fat, two-thirds of which is monounsaturated. They also provide close to 20 essential health-boosting nutrients, including:

  • Fiber
  • Vitamin E
  • B-vitamins
  • Folic acid
  • Potassium (more than twice the amount found in a banana), which can help balance your  vitally important potassium to sodium ratio

Due to its beneficial raw fat content, avocado enables your body to more efficiently absorb fat-soluble nutrients (such as alpha- and beta-carotene and lutein) in other foods eaten in conjunction.

One 2005 study4 found that adding avocado to salad allowed the volunteers to absorb three to five times more carotenoids antioxidant molecules, which help protect your body against free radical damage.

An Avocado a Day May Help Lower Bad Cholesterol

Previous research has suggested that avocados might help improve lipid profiles, both in healthy individuals and in those with mild hypercholesterolemia (elevated cholesterol levels).

In one such study,5 healthy individuals saw a 16 percent decrease of serum total cholesterol level following a one-week long diet high in monounsaturated fat from avocados.

In those with elevated cholesterol levels, the avocado diet resulted in a 17 percent decrease of serum total cholesterol, and a 22 percent decrease of both LDL-cholesterol and triglycerides, along with an 11 percent increase of the so-called “good” HDL cholesterol.

More recently, researchers at Pennsylvania State University tested three different cholesterol-reducing diets, to assess and compare their effectiveness.6,7,8 Forty-five overweight participants were enrolled in the study, and were assigned to follow one of the tree diets:

  1. Low-fat diet, where saturated fats were substituted for more carbohydrates, including plenty of fruit and whole grains
  2. Moderate-fat diet (without avocado), where saturated fats were substituted with monounsaturated fats in the form of canola and sunflower oil. About 34 percent of daily calories came from fat, but aside from that, it was very similar to the low-fat diet, which included poultry and low amounts of red meat
  3. Moderate-fat diet with avocado. Aside from including one whole Hass avocado per day, this diet was identical to the other moderate-fat diet, and the overall fat ratio was the same

The results, reported by the NPR,9 “surprised” the researchers:

“At the end of the study, the researchers found that the avocado diet led to significant reductions in LDL cholesterol, compared with the other two diets.

To put the difference in perspective, the avocado diet decreased LDL cholesterol about 14 milligrams per deciliter of blood. Compare that with a decrease of about 7 mg/dL for the low-fat diet, and about a 8 mg/dl drop from the moderate-fat diet.

“I was surprised to see the added benefit [of the avocado],” Penny Kris-Etherton, a nutrition scientist at Penn State and the lead author of the study, tells us.” It’s something in the avocado” other than just the fat composition, she says.”

All Fats Are Not Created Equal

It’s worth noting that canola and other vegetable oils (used in the moderate-fat diets in the featured study) are typically hydrogenated, which  means they contain trans fats, and trans fats wreak havoc on your heart and cardiovascular health. So I for one am not surprised at the results of this study.

Previous research10 has actually shown that replacing saturated fats with carbohydrates and omega-6 polyunsaturated fats (found in soybean, corn, and safflower oil) leads to increased small, high-density LDL particles, increased oxidized LDL, and reduced HDL.

Research has confirmed that large LDL particles do not contribute to heart disease. The small, dense LDL particles, however, do contribute to the build-up of plaque in your arteries, and trans fat increases small, dense LDL. (Saturated fat, on the other hand, increases large, fluffy—and benign—LDL.)

Research has also shown that small, dense LDL particles are increased by eatingrefined sugar and carbohydrates, such as bread, pasta, and most processed foods. Together, trans fats and refined carbs do far more harm than saturated fat ever possibly could. One tool designed to help you eliminate trans fats are the Naturally Savvy Get Healthy Challenges that I helped create.

A Note on the DASH Diet…

On a brief side note: In the CBS video above, they also make mention of the DASH diet, which has been found to lower blood pressure by as much as five points, rivaling the effects of blood pressure lowering medications.

The DASH diet is quite similar to the Mediterranean diet, promoting the consumption of vegetables, fruits, lean protein, whole grains, and low-fat dairy, and recommends avoiding sugars, red meat, and salt.

Many believe that the low-sodium is responsible for its success. However, there’s compelling evidence suggesting that the real reasons it works so well for both hypertension and weight loss is because it increases potassium and restricts your intake of fructose—as does the Mediterranean diet.

Fructose is actually a far more important factor than salt when it comes to hypertension. The connecting link between fructose consumption and hypertension lies in the uric acid produced. Uric acid is a byproduct of fructose metabolism, and increased uric acid levels drive up your blood pressure.

Now, when you reduce sugar in your diet (from sources such as added sugars, processed fructose, grains of all kinds, and processed foods), you need to increase the amount of healthy fat. And avocado is an excellent choice to bolster your fat consumption and overall nutrition.

I have been consuming an avocado daily for the last several years. On most days, I will add a whole avocado to my salad, which I eat for lunch. This increases my healthy fat and calorie intake without seriously increasing my protein or carbohydrate intake. You can also add about ¼ to 1/3 of an avocado as a healthy banana substitute when making smoothies or your protein shake.

Avocado Benefits Your Heart and Brain

Besides its beneficial influence on your cholesterol, avocados have also been found to provide other heart-healthy benefits. For example, one interesting 2012 study11found that eating one-half of a fresh medium Hass avocado with a hamburger significantly inhibited the production of the inflammatory compound Interleukin-6 (IL-6), compared to eating a burger without fresh avocado.

Also, just like avocado does not raise your blood sugar levels, fresh avocado did not increase triglyceride levels beyond what was observed when eating the burger alone, despite the avocado supplying extra fat and calories. According to lead author David Heber, MD, PhD, the findings offer “promising clues” about avocado’s ability to benefit vascular function and heart health. Healthy fats are also vital for optimal brain function, and for the prevention of degenerative brain disorders like Alzheimer’s. As noted in a recent issue of Scientific American:12

“The brain thrives on a fat-rich, low carbohydrate diet, which unfortunately is relatively uncommon in human populations today,” reports David Perlmutter, author of Grain Brain. “Mayo Clinic researchers showed that individuals favoring carbohydrates in their diets had a remarkable 89 percent increased risk for developing dementia as contrasted to those whose diets contained the most fat.

Having the highest levels of fat consumption was actually found to be associated with an incredible 44 percent reduction in risk for developing dementia.” …‘Good’ fats include monounsaturated fats, found abundantly in olive oil, peanut oil, hazelnuts, avocados and pumpkin seeds, and polyunsaturated fats (omega 3 and omega 6), which are found in flaxseed oil, chia seeds, marine algae oil and walnuts.”

To Maximize Benefits, Peel Your Avocado the Right Way

Interestingly, the manner in which you de-skin your avocado can affect how much of its valuable phytonutrients you get out of it. UCLA research has shown that the greatest concentration of beneficial carotenoids, for example, is located in the dark green fruit closest to the inside of the peel. In 2010, the California Avocado Commission issued guidelines for getting the most out of your avocado by peeling it the right way.13 To preserve the area with the greatest concentration of antioxidants, you’re best off peeling the avocado with your hands, as you would a banana:

  1. First, cut the avocado length-wise, around the seed
  2. Holding each half, twist them in the opposite directions to separate them from the seed
  3. Remove the seed
  4. Cut each half, lengthwise
  5. Next, using your thumb and index finger, simply peel the skin off each piece

How to Get More Avocado into Your Diet

While avocado is commonly eaten raw, on salad or alone, there are many other ways to include avocado in your diet. Its creamy, mild flavor tends to go well with many foods, making it a refreshing and nutritious addition to various recipes. For example, you can use avocado:

  • As a fat replacement in baking. Simply replace the fat called for (such as oil, butter, or shortening) with an equal amount of avocado
  • As a first food for babies, in lieu of processed baby food
  • In soups. For examples, see Lucy Lock’s Chilled Mediterranean Soup, or herRaw Creamy Carrot Soup
  • As a banana substitute in smoothies or your protein shake

The California Avocado Commission’s website14 contains hundreds of unique recipes that include avocado. All in all, avocado may be one of the most beneficial superfoods out there, and may be particularly valuable if you’re struggling with insulin and leptin resistance, diabetes, or any other risk factors for heart disease. Last but not least, avocados are also one of the safest fruits you can buy conventionally-grown, as their thick skin protects the inner fruit from pesticides.

On top of that, avocados have been rated as one of the safest commercial crops in terms of pesticide application,15 so there’s no real need to spend extra money on organic avocados. I’ve had my own team test avocados from a variety of growers in different countries, sold in several major grocery stores, and they all tested free and clear of harmful chemicals.

Magnesium: An Invisible Deficiency That Could Be Harming Your Health

January 23, 2015 By Sherri

Magnesium: An Invisible Deficiency That Could Be Harming Your Health

Magnesium Deficiency

Story at-a-glance+

By Dr. Mercola

Magnesium is a mineral used by every organ in your body, especially your heart, muscles, and kidneys.1 If you suffer from unexplained fatigue or weakness, abnormal heart rhythms or even muscle spasms and eye twitches, low levels of magnesium could be to blame.

If you’ve recently had a blood test, you might assume it would show a magnesium deficiency. But only 1 percent of magnesium in your body is distributed in your blood, making a simple sample of magnesium from a serum magnesium blood test not very useful.

Most magnesium is stored in your bones and organs, where it is used for many biological functions. Yet, it’s quite possible to be deficient and not know it, which is why magnesium deficiency has been dubbed the “invisible deficiency.”

By some estimates, up to 80 percent of Americans are not getting enough magnesium and may be deficient. Other research shows only about 25 percent of US adults are getting the recommended daily amount of 310 to 320 milligrams (mg) for women and 400 to 420 for men.2

Even more concerning, consuming even this amount is “just enough to ward off outright deficiency,” according to Dr. Carolyn Dean, a medical and naturopathic doctor.

Magnesium Deficiency May Trigger 22 Medical Conditions

Magnesium is often thought of primarily as a mineral for your heart and bones, but this is misleading. Researchers have now detected 3,751 magnesium-binding sites on human proteins, indicating that its role in human health and disease may have been vastly underestimated.3

Magnesium is also found in more than 300 different enzymes in your body and plays a role in your body’s detoxification processes, making it important for helping to prevent damage from environmental chemicals, heavy metals, and other toxins. In addition, magnesium is necessary for:

  • Activating muscles and nerves
  • Creating energy in your body by activating adenosine triphosphate (ATP)
  • Helping digest proteins, carbohydrates, and fats
  • Serving as a building block for RNA and DNA synthesis
  • Acting as a precursor for neurotransmitters like serotonin

Dr. Dean has studied and written about magnesium for more than 15 years. The latest addition of her book, The Magnesium Miracle, came out in 2014 and in it you can learn about 22 medical areas that magnesium deficiency triggers or causes, all of which have all been scientifically proven. This includes:4

Anxiety and panic attacks Asthma Blood clots
Bowel diseases Cystitis Depression
Detoxification Diabetes Fatigue
Heart disease Hypertension Hypoglycemia
Insomnia Kidney disease Liver disease
Migraine Musculoskeletal conditions (fibromyalgia, cramps, chronic back pain, etc.) Nerve problems
Obstetrics and gynecology (PMS, infertility, and preeclampsia) Osteoporosis Raynaud’s syndrome
Tooth decay

Early signs of magnesium deficiency include loss of appetite, headache, nausea, fatigue, and weakness. An ongoing magnesium deficiency can lead to more serious symptoms, including:

Numbness and tingling Muscle contractions and cramps Seizures
Personality changes Abnormal heart rhythms Coronary spasms

The Role of Magnesium in Diabetes, Cancer, and More

Most people do not think about magnesium when they think about how to prevent chronic disease, but it plays an essential role. For instance, there have been several significant studies about magnesium’s role in keeping your metabolism running efficiently—specifically in terms of insulin sensitivity, glucose regulation, and protection from type 2 diabetes.

Higher magnesium intake reduces risk of impaired glucose and insulin metabolism and slows progression from pre-diabetes to diabetes in middle-aged Americans.5Researchers stated, “Magnesium intake may be particularly beneficial in offsetting your risk of developing diabetes, if you are high risk.”

Multiple studies have also shown that higher magnesium intake is associated with a higher bone mineral density in both men and women,6 and research from Norway has even found an association between magnesium in drinking water and a lower risk of hip fractures.7

Magnesium may even help lower your risk of cancer, and a study published in theAmerican Journal of Clinical Nutrition showed that higher intakes of dietary magnesium were associated with a lower risk of colorectal tumors.8

Results from the meta-analysis indicated that for every 100-mg increase in magnesium intake, the risk of colorectal tumor decreased by 13 percent, while the risk of colorectal cancer was lowered by 12 percent. The researchers noted magnesium’s anti-cancer effects may be related to its ability to reduce insulin resistance, which may positively affect the development of tumors.

Surprising Factors That Influence Your Magnesium Levels

Seaweed and green leafy vegetables like spinach and Swiss chard can be excellent sources of magnesium, as are some beans, nuts, and seeds, like pumpkin, sunflower, and sesame seeds. Avocados also contain magnesium. Juicing your vegetables is an excellent option to ensure you’re getting enough of them in your diet.

However, most foods grown today are deficient in magnesium and other minerals, so getting enough isn’t simply a matter of eating magnesium-rich foods (although this isimportant too). According to Dr. Dean:

“Magnesium is farmed out of the soil much more than calcium… A hundred years ago, we would get maybe 500 milligrams of magnesium in an ordinary diet. Now we’re lucky to get 200 milligrams.”

Herbicides, like glyphosate also act as chelators, effectively blocking the uptake and utilization of minerals in so many foods grown today. As a result, it can be quite difficult to find truly magnesium-rich foods. Cooking and processing further depletes magnesium.

Meanwhile, certain foods can actually influence your body’s absorption of magnesium. If you drink alcohol in excess, for instance, it may interfere with your body’s absorption of vitamin D, which in turn is helpful for magnesium absorption. If you eat a lot of sugar, this can also cause your body to excrete magnesium through your kidneys, “resulting in a net loss,” according to Dr. Danine Fruge, associate medical director at the Pritikin Longevity Center in Florida.9 The following factors are also associated with lower magnesium levels:10

  • Excessive intake of soda or caffeine
  • Menopause
  • Older age (older adults are more likely to be magnesium deficient because absorption decreases with age and the elderly are more likely to take medications that can interfere with absorption)
  • Certain medications, including diuretics, certain antibiotics (such as gentamicin and tobramycin), corticosteroids (prednisone or Deltasone), antacids, and insulin
  • An unhealthy digestive system, which impairs your body’s ability to absorb magnesium (Crohn’s disease, leaky gut, etc.)

Calcium, Vitamin K2, and Vitamin D Must Be Balanced with Magnesium

It may seem like you could remedy the risks of low magnesium simply by taking a supplement, but it’s not quite that simple. When you’re taking magnesium, you need to consider calcium, vitamin D3 and vitamin K2 as well, since these all work synergistically with one another. Excessive amounts of calcium without the counterbalance of magnesium can lead to a heart attack and sudden death, for instance. Research on the Paleolithic or caveman diet has shown that the ratio of calcium to magnesium in the diet that our bodies evolved to eat is 1-to-1.11Americans in general tend to have a higher calcium-to-magnesium ratio in their diet, averaging about 3.5-to-1.

If you have too much calcium and not enough magnesium, your muscles will tend to go into spasm, and this has consequences for your heart in particular. “What happens is, the muscle and nerve function that magnesium is responsible for is diminished. If you don’t have enough magnesium, your muscles go into spasm. Calcium causes muscle to contract. If you had a balance, the muscles would do their thing. They’d relax, contract, and create their activity,” Dr. Dean explains.

When balancing calcium and magnesium, also keep in mind that vitamins K2 and D need to be considered. These four nutrients perform an intricate dance together, with one supporting the other. Lack of balance between these nutrients is one of the reasons why calcium supplements have become associated with increased risk of heart attacks and stroke, and why some people experience vitamin D toxicity. Part of the explanation for these adverse side effects is that vitamin K2 keeps calcium in its appropriate place. If you’re K2 deficient, added calcium can cause more problems than it solves, by accumulating in the wrong places, like your soft tissue.

Similarly, if you opt for oral vitamin D, you need to also consume it in your food or take supplemental vitamin K2 and more magnesium. Taking mega doses of vitamin D supplements without sufficient amounts of K2 and magnesium can lead to vitamin D toxicity and magnesium deficiency symptoms, which include inappropriate calcification that may damage your heart.

Tips for Increasing Your Magnesium Levels

One way to really increase your magnesium, as well as many other important plant-based nutrients, is by juicing your greens. I typically drink one pint to one quart of fresh green vegetable juice every day, and this is one of my primary sources of magnesium. Organic foods may have more magnesium if grown in nutrient-rich soils but it is very difficult to make that determination. If you opt for a supplement, be aware that there are a wide variety of magnesium supplements on the market, because magnesium must be bound to another substance. There’s simply no such thing as a 100 percent magnesium supplement.

The substance used in any given compound can affect the absorption and bioavailability of the magnesium, and may provide slightly different, or targeted, health benefits. The table that follows summarizes some of the differences between the various forms. Magnesium threonate and citrate are some of the best sources, as it seems to penetrate cell membranes, including your mitochondria, which results in higher energy levels. Additionally, it also penetrates your blood-brain barrier and seems to do wonders to treat and prevent dementia and improve memory. If you take a supplement, you can use the “bowel test” to determine if you’re taking too much magnesium. Dr. Dean explains:12

“The best way to tell if you are getting enough magnesium is the “bowel test”. You know when you have too much magnesium when your stools become loose. This, in fact, may be a blessing for people with constipation… [which] is one of the many ways magnesium deficiency manifests.”

Besides taking a supplement, another way to improve your magnesium status is to take regular Epsom salt baths or foot baths. Epsom salt is a magnesium sulfate that can absorb into your body through your skin. Magnesium oil can also be used for topical application and absorption. Whatever supplement you choose, be sure to avoid any containing magnesium stearate, a common but potentially hazardous additive.

Magnesium glycinate is a chelated form of magnesium that tends to provide the highest levels of absorption and bioavailability and is typically considered ideal for those who are trying to correct a deficiency. Magnesium oxide is a non-chelated type of magnesium, bound to an organic acid or a fatty acid. Contains 60 percent magnesium, and has stool softening properties
Magnesium chloride/Magnesium lactate contain only 12 percent magnesium, but has better absorption than others, such as magnesium oxide, which contains five times more magnesium Magnesium sulfate/Magnesium hydroxide (milk of magnesia) are typically used as laxatives. Be aware that it’s easy to overdose on these, so ONLY take as directed
Magnesium carbonate, which has antacid properties, contains 45 percent magnesium Magnesium taurate contains a combination of magnesium and taurine, an amino acid. Together, they tend to provide a calming effect on your body and mind
Magnesium citrate is magnesium with citric acid, which like most magnesium supplements has laxative properties but is well absorbed and cost effective Magnesium threonate is a newer, emerging type of magnesium supplement that appears promising, primarily due to its superior ability to penetrate the mitochondrial membrane, and may be the best magnesium supplement on the market

Your Practical Guide to Omega-3 Benefits and Supplementation

January 23, 2015 By Sherri

By Dr. Mercola

Omega-3 in SalmonTime and again, I have emphasized that omega-3 fats are essential to your overall health. And I am not alone – other health experts stress the same, and decades of research have been devoted to discovering the many health benefits of omega-3. Omega-3 comes from both animal and plant sources, most notably from krill oil and fish oil. They have become a multibillion-dollar business, with Americans spending about 2.6 billion dollars on nutritional supplements and foods fortified with omega-3 fats.1

Get the lowdown on omega-3 – its different types and sources, the omega-3 and omega-6 balance you should strive to achieve, and how to know if you are getting the highest-quality omega-3 fats for the wealth of health gains.

Types of Omega-3 Fats

Omega-3 fats are acquired from both animal and plant sources, but there is a lot of confusion when it comes to what type you should take to get the best omega-3 benefits.

Marine animals such as fish and krill provide eicosapentaenoic acid (EPA) anddocosahexaenoic acid (DHA), which are mostly promoted for their protective effects on your heart. Flaxseed, chia, hemp, and a few other foods, on the other hand, offeralpha-linoleic acid (ALA). 2

You would want to choose an animal-based variety – most of the health benefits linked to omega-3 fats are linked to the animal-based EPA and DHA, not the plant-based ALA.

Furthermore, ALA is converted into EPA and DHA in your body at a very low ratio. What this means is that even if you consume large amounts of ALA, your body can only convert a relatively small amount into EPA and DHA, and only when there are sufficient enzymes.

Remember, though, that plant-based omega-3 fats are NOT inherently harmful or should be avoided. Ideally, what you want to do is include an animal-based form in your diet. For instance, you can combine flax and hemp in your diet with animal-based omega-3s.

A Rundown of Omega-3 Benefits

Omega-3 ranks among the most important essential nutrients out there today.3 In 2008, the American Journal of Clinical Nutrition4, 5, 6 published three studies investigating the role of EPA and DHA omega-3 fatty acids in elderly populations.

Low concentrations of EPA and DHA resulted in an increased risk of death from all causes, as well as accelerated cognitive decline. The studies also suggest that a higher intake of omega-3s may bring certain health benefits that short-term supplementation cannot give.

Here are other evidence of omega-3 benefits:

    1. Omega-3 benefits your heart health. An Italian study (GISSI)7 of 11,324 heart attack survivors found that patients supplementing with fish oils markedly reduced their risk of another heart attack, stroke, or death. In a separate study, 8 American medical researchers reported that men who consumed fish once or more every week had a 50 percent lower risk of dying from a sudden cardiac event than do men who eat fish less than once a month.
    2. Omega-3 normalizes and regulates your cholesterol triglyceride levels.Compared to a statin, both fish oil and krill oil are more efficient in doing this. According to a study comparing the efficiency of krill and fish oils in reducing triglyceride levels,9 both oils notably reduced the enzyme activity that causes the liver to metabolize fat, but krill had a more pronounced effects, reducing liver triglycerides significantly more.

Fasting triglyceride levels are a powerful indication of your ability to have healthy lipid profiles, which can be indicative of your heart health.

Studies have also shown that omega-3 fats are anti-arrhythmic (preventing or counteracting cardiac arrhythmia), anti-thrombotic (prevents thrombosis or a blood clot within a blood vessel), anti-atherosclerotic (preventing fatty deposits and fibrosis of the inner layer of your arteries), and anti-inflammatory (counteracting inflammation – the heat, pain, swelling, etc).

    1. DHA affects your child’s learning and behavior. Do you want to maximize your child’s intellectual potential? A study published in Plos One in June 201310 linked low levels of DHA with poorer reading, and memory and behavioral problems in healthy school-age children. In another study published in the American Journal of Clinical Nutrition in August 2013,11 children who consumed an omega-3 fat supplement as infants scored higher on rule learning, vocabulary, and intelligent testing at ages 3 to 5.

Previous research also found that children with attention deficit hyperactivity disorder (ADHD) and related behavior or learning disabilities are more likely to have low omega-3 fat levels.

Omega-3 has such great impact on your brain health – EPA and DHA keep the dopamine levels in your brain high, increase neuronal growth in the frontal cortex of your brain, and increase cerebral circulation.

Omega-3 has been found to save the lives of children going through short bowel syndrome (SBS)
    1. Omega-3 has been found to save the lives of children going through short bowel syndrome (SBS), which is uncommon but impacts thousands of people in the United States. SBS can occur from birth (when a portion of the intestine fails to develop) or due to an infectious inflammatory disease striking premature newborns. In adults, it can be caused by surgery for Crohn’s disease or injury.

Alarmed by the situation, Dr. Mark Puder, surgeon at Children’s Hospital Boston,12 said that they knew most of the children with SBS were going to die. Then the physicians noted that when the kids were given the nutritional supplement Omegaven (made of fish oil), they began to improve drastically.

The fish oil treatment was given to 112 children at the hospital, where more than 90 percent of the children with SBS are still alive. There has been striking results that the fish oil supplement is also made available at 70 hospitals worldwide.

Omega-3 benefits cover many areas of health, from mental and behavioral health to preventing premature death from disease, including the following:

Coronary heart disease and stroke Essential fatty acid deficiency in infancy (retinal and brain development) General brain function, including memory and Parkinson’s disease
ADHD Autoimmune disorders, e.g. lupus and nephropathy Osteoporosis
Crohn’s disease Cancers of the breast, colon, and prostate Rheumatoid arthritis

You May Be Running Low on These Beneficial Fats

Omega-3 Deficiency Affects the HeartMost people fail to consume sufficient amounts of omega-3 fats, which makesomega-3 deficiency likely the sixth biggest killer of Americans. This deficiency can cause or contribute to serious mental and physical health problems, and may be a significant underlying factor of up to 96,000 premature deaths each year.

In fact, dietary fat intake has been among the most widely studied dietary risk factors for breast and prostate cancers. Two studies from 2002 explain how omega-3 can protect against breast cancer. BRCA1 (breast cancer gene 1) and BRCA2 (breast cancer gene 2) are two tumor suppressor genes that, when functioning normally, help repair DNA damage, a process that also prevents tumor development.

Omega-3 and omega-6 fats have been found to influence these two genes – omega-3 tends to reduce cancer cell growth, while highly processed and toxic omega-6 has been found to cause cancer growth.

Considering that omega-3 deficiency is a common underlying factor for cancer and heart disease, it is no longer surprising for statistics to show that this deficiency may be responsible for nearly 100,000 deaths every year.

Special attention should also be given to the fact that most women have major deficiencies of omega-3. A 1991 study at the Mayo Clinic focused on 19 “normal” pregnant women consuming “normal diets,” and it showed that all were deficient in omega-3 fats. Another study compared Inuit (Eskimo) women to Canadian women, and it revealed omega-3 deficiency in the milk of the Canadian nursing moms.

Animal cells cannot form omega-3, so a fetus must obtain all of its omega-3 fatty acids from its mother’s diet. A mother’s dietary intake and plasma concentrations of DHA directly influence the DHA level of the developing fetus, impacting the child’s brain and eye health.

So remember that if you are pregnant, your baby is dependent on the omega-3 from your diet via breast milk. It is then crucial that you maintain adequate omega-3 supply.

The Omega-3-Omega-6 Balance You Should Maintain in Your Body

omega 3 capletsOmega-3 and omega-6 are two types of fat that are essential for human health. However, the typical American consumes far too many omega-6 fats in her diet while consuming very low omega-3 levels.

The ideal ratio of omega-6 to omega-3 fats is 1:1. Our forefathers evolved over millions of years on this ratio. Today, however, our ratio averages from 20:1 to 50:1 – this spells serous dangers to your well-being! In fact, mainstream media has finally reported that lack of omega-3 is among the most serious and pressing health issues plaguing our world.Omega-6 is primarily sourced from corn, soy, canola, safflower, and sunflower oils. These are overabundant in the typical diet, which accounts for excess omega-6 levels.

Omega-6 fats predominate the diet in the US, and this encourages the production ofinflammation in your body. Many scientists believe that one reason there is a high incidence of heart disease, hypertension, diabetes, obesity, premature aging, and some cancer forms today is this profound omega-3-omega-6 imbalance.

Sources of Animal-Based Omega-3 Fats

Perhaps you are wondering what animal-based omega-3 options are available for you. Here are the primary ones:

    • Fish – In a perfect world, fish can provide you all the omega-3s you need. Unfortunately, the vast majority of the fish supply is now heavily tainted with industrial toxins and pollutants, such as heavy metals, PCBs, and radioactive poisons. These toxins make eating fish no longer recommended.

About the only exception are wild-caught Alaskan salmon and very small fish like sardines. The highest concentrations of mercury are found in large carnivorous fish like tuna, sea bass, and marlin. You may need to be especially cautious canned tuna as well, as independent testing by the Mercury Policy Project found that the average mercury concentration in canned tuna is far over the “safe limits” of the Environmental Protection Agency (EPA).

It is also important that you avoid farmed salmon, which contains only about half of the omega-3 levels of wild salmon. It may also harbor a range of contaminants, including environmental toxins, synthetic astaxanthin, and harmful metabolic byproducts and agrichemical residues of GMO corn- and soy-based feed they are given.

    • Fish oil – Fish oil is among the primary ways that people enhance their intake of omega-3 fats. High-quality fish oils can certainly provide many health benefits. However, this oil is weak in antioxidants. This means that as you increase your omega-3 intake through fish oil consumption, you actually increase your need for added antioxidant protection.

This happens because fish oil is a bit perishable, and oxidation leads to the formation of harmful free radicals. Antioxidants are therefore necessary to ensure that the fish oil doesn’t oxidize and become rancid in your body.

    • Cod liver oil – I no longer recommend this because of the potential for problematic ratios of vitamins A and D.
    • Krill oil – This is my preferred choice for animal-based omega-3 fats. Its antioxidant potency is 48 times higher than fish oil. It also contains astaxanthin, a marine-source flavonoid that creates a special bond with the EPA and DHA to allow direct metabolism of the antioxidants, making them more bioavailable.

Krill Oil BenefitsKrill – or “okiami” as the Japanese call it – are small, shrimp-like creatures that are a cherished food source in Asia since the 19th century or earlier.

Krill harvesting is a completely sustainable and one of the most eco-friendly on the planet. Krill are the largest biomass in the world and can be found in all oceans. Antarctic krill, by far the most abundant, is under the management of an international organization of 25 countries known as the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

Antarctic krill biomass is using strict international precautionary catch limit regulations, reviewed regularly to assure sustainability. No shortage of krill has ever been forecasted by CCAMLR.

Fish oil and krill oil are the two major players in the realm of animal-based omega-3 fats. But I have plenty of reasons to believe that krill oil offers superior benefits. In fact, two studies illustrate this:

  • A January 2011 study in Lipids13 found that the metabolic effects of the two oils are “essential similar,” but krill oil is as effective as fish oil despite containing less EPA and DHA.
  • Another data, still unpublished in that year, suggests that krill oil is absorbed up to 10 to 15 times as well as fish oil. Its molecular composition14 is said to account for this better absorbability.

This Mercola infographic will provide a summary of why I choose krill over fish oil.

Giving Omega-3 Fats to Your Child

From the time of your pregnancy through your child’s later life, omega-3 fats DHA and EPA have a radically important role in her brain health and other functions. I recommend supplementing with krill oil before and during pregnancy, and while you breastfeed. Babies receive DHA through your breast milk, so continuing breastfeeding through the first year will give your child a great headstart for health and success.

As soon as your child can safely swallow a capsule, she can start taking a high-quality krill oil supplement, which should be kid-sized or about half the size of a regular capsule. The supplement should also be odor-free, making it easy and palatable for children to swallow.

Final Recommendations

Make sure that you and your children get the right type of omega-3 fats. Go for a pollution-free, eco-friendly, and highly sustainable source, like krill oil. The good news is that krill oil appears to work at a lower dose, and this results in major cost savings, making it more affordable than fish oil.

I always emphasize making healthy, wholesome food choices to get all the nutrients you need. In this case, supplementing your diet with a high-quality source of omega-3 fats, such as real krill oil, is a surefire way to help optimize your health.

New Study Shows Evidence That Vitamin K2 Positively Impacts Inflammation

New Study Shows Evidence That Vitamin K2 Positively Impacts Inflammation

Chronic Pain

Story at-a-glance+

By Dr. Mercola

Chronic inflammation is low-grade and systemic, often silently damaging your tissues over an extended period of time. This process can go on for decades without you noticing, until disease symptoms suddenly occur long after irreversible damage is done.

Chronic inflammation is the source of many diseases, including cancer, obesity, and heart disease, which essentially makes it the leading cause of death in the U.S.

Knowing how to keep chronic inflammation at bay is also invaluable in protecting your health, which brings us to a new study on vitamin K2 presented at the 13th International Nutrition and Diagnostics Conference (INDC 2013) in the Czech Republic.1

The study revealed that a specific type of vitamin K2 (MK-7) may help prevent inflammation. But before I get into the details, it’s important to understand the different forms that vitamin K comes in.

The Two Basic Types of Vitamin K – K1 and K2

Vitamin K can be classified as either K1 or K2:

    1. Vitamin K1: Found in green vegetables, K1 goes directly to your liver and helps you maintain a healthy blood clotting system. (This is the kind of K that infants need to help prevent a serious bleeding disorder.)

It is also vitamin K1 that keeps your own blood vessels from calcifying, and helps your bones retain calcium and develop the right crystalline structure.

    1. Vitamin K2: Bacteria produce this type of vitamin K. It is present in high quantities in your gut, but unfortunately most is passed out in your stool. K2 goes straight to vessel walls, bones and tissues other than your liver.

It is present in fermented foods, particularly cheese and the Japanese food natto, which is by far the richest source of K2.

Vitamin K1 can convert to K2 in your body, but there are some problems with this; the amount of K2 produced by this process alone is typically insufficient. Making matters even more complex, there are several different forms of vitamin K2. MK-8 and MK-9 come primarily from dairy products. MK-4 and MK-7 are the two most significant forms of K2 and act very differently in your body:

    • MK-4 is a synthetic product, very similar to vitamin K1, and your body is capable of converting K1 into MK-4. However, MK-4 has a very short biological half-life of about one hour, making it a poor candidate as a dietary supplement.

After reaching your intestines, it remains mostly in your liver, where it is useful in synthesizing blood-clotting factors.

    • MK-7 is a newer agent with more practical applications because it stays in your body longer; its half-life is three days, meaning you have a much better chance of building up a consistent blood level, compared to MK-4 or K1. MK-7 is extracted from the Japanese fermented soy product called natto.

You could actually get loads of MK-7 from consuming natto, as it is relatively inexpensive and is available in most Asian food markets. Few Americans, however, tolerate its smell and slimy texture.

Vitamin K2 as MK-7 Helps Prevent Inflammation in Your Body

Vitamin K2, particularly menaquinone-7 (MK-7), has been the subject of much research because it stays active in your body longer so you are able to benefit from much lower levels. The study from the Czech Republic evaluated the role of MK-7 in inflammation and found that it prevents inflammation by inhibiting pro-inflammatory markers produced by white blood cells called monocytes.

NattoPharma reported:2

“The novel finding in our study supplements our three-year clinical study showing MK-7’s ability to slow down cardiovascular aging and osteoporosis, and it should further serve as the catalyst to create the urgency of daily consumption of MK-7… We know that in Western populations, most people do not obtain enough due to modern diet.

Our food is increasingly deficient in vitamin K2 in particular, and up to 98% of the general healthy population may be vitamin K2 insufficient with long-term detrimental impact on bone and cardiovascular health.”

It’s important to realize that dietary components can either trigger or preventinflammation from taking root in your body. For example, whereas synthetic trans fats and sugar, particularly fructose, will increase inflammation, eating healthy fats such as animal-based omega-3 fats found in krill oil or the essential fatty acid gamma linolenic acid (GLA) will help to reduce them.

MK-7 appears to be one more healthful natural substance that can be added to the anti-inflammatory list, and I’ll discuss the best food sources of this shortly.

As for inflammation in general, if you have not already addressed your diet, this would be the best place to start, regardless of whether you’re experiencing symptoms of chronic inflammation or not. To help you get started, I suggest following my freeOptimized Nutrition Plan, which starts at the beginner phase and systematically guides you step-by-step to the advanced level.

What Else Is Vitamin K2 Good For?

The health benefits of vitamin K2 go far beyond blood clotting, which is done by vitamin K1, and vitamin K2 also works synergistically with a number of other nutrients, including calcium and vitamin D. Its biological role is to help move calcium into the proper areas in your body, such as your bones and teeth. It also plays a role in removing calcium from areas where it shouldn’t be, such as in your arteries and soft tissues.

Dr. Kate Rheaume-Bleue, a naturopathic physician, estimates that about 80 percent of Americans do not get enough vitamin K2 in their diet to activate their K2 proteins to shuttle the calcium where it needs to be and remove it from the places where it shouldn’t be. Vitamin K2 deficiency leaves you vulnerable to a number of chronic diseases, including:

Osteoporosis Heart disease Heart attack and stroke
Inappropriate calcification, from heel spurs to kidney stones Brain disease Cancer

 

“I talked about vitamin K2 moving calcium around the body. Its other main role is to activate proteins that control cell growth. That means K2 has a very important role to play in cancer protection,” Rheaume-Bleue says. “When we’re lacking K2, we’re at much greater risk for osteoporosis, heart disease, and cancer. And these are three concerns that used to be relatively rare. Over the last 100 years, as we’ve changed the way we produced our food and the way we eat, they have become very common.”

Researchers are also looking into other health benefits, as well. For example, one study published in the journal Modern Rheumatology found that vitamin K2 has the potential to improve disease activity besides osteoporosis in those with rheumatoid arthritis (RA).3 Another, published in the journal Science found that vitamin K2 serves as a mitochondrial electron carrier, thereby helping maintain normal adenosine triphosphate (ATP) production in mitochondrial dysfunction, such as that found in Parkinson’s disease.4 Further, according to a 2009 Dutch study, subtypes MK-7, MK-8 and MK-9 in particular are associated with reduced vascular calcification even at small dietary intakes (as low as 1 to 2 mcg per day).5

What Are the Best Food Sources of Vitamin K2, Including MK-7?

You can obtain all the K2 you’ll need (about 200 micrograms) by eating 15 grams of natto daily, which is half an ounce. However, natto is generally not appealing to a Westerner’s palate, so you can also find vitamin K2, including MK-7, in other fermented foods. Fermented vegetables, which are one of my new passions, primarily for supplying beneficial bacteria back into your gut, can be a great source of vitamin K if you ferment your own using the proper starter culture.

We had samples of high-quality fermented organic vegetables made with our specific starter culture tested, and were shocked to discover that not only does a typical serving of about two to three ounces contain about 10 trillion beneficial bacteria, but it also contained 500 mcg of vitamin K2.

Note that not every strain of bacteria makes K2. For example, most yogurts have almost no vitamin K2. Certain types of cheeses are very high in K2, and others are not. It really depends on the specific bacteria. You can’t assume that any fermented food will be high in K2, but some fermented foods are very high in K2, such as natto. Others, such as miso and tempeh, are not high in K2. In my interview with Dr. Rheaume-Bleue, she identified the cheeses highest in K2 are Gouda and Brie, which contain about 75 mcg per ounce. Additionally, scientists have found high levels of MK-7 in a type ofcheese called Edam.

How Much Vitamin K2 Do You Need?

Although the exact dosing is yet to be determined, Dr. Cees Vermeer, one of the world’s top researchers in the field of vitamin K, recommends between 45 mcg and 185 mcg daily for adults. You must use caution on the higher doses if you take anticoagulants, but if you are generally healthy and not on these types of medications, I suggest 150 mcg daily. Fortunately, you don’t need to worry about overdosing on K2—people have been given a thousand-fold “overdose” over the course of three years, showing no adverse reactions (i.e., no increased clotting tendencies). If you have any of the following health conditions, you’re likely deficient in vitamin K2 as they are all connected to K2:

  • Do you have osteoporosis?
  • Do you have heart disease?
  • Do you have diabetes?

Please note also that if you opt for oral vitamin D, you also need to consume vitamin K2 in your food or take supplemental vitamin K2, as they worksynergistically together and an imbalance may actually be harmful. If you do not have any of those health conditions, but do NOT regularly eat high amounts of the following foods, then your likelihood of being vitamin K2 deficient is still very high:

  • Grass-fed organic animal products (i.e. eggs, butter, dairy)
  • Certain fermented foods such as natto, or vegetables fermented using a starter culture of vitamin K2-producing bacteria
  • Certain cheeses such as Brie and Gouda (as mentioned, these two are particularly high in K2, containing about 75 mcg per ounce)

If You’re Considering a Vitamin K2 Supplement…

There’s no way to test for vitamin K2 deficiency. But by assessing your diet and lifestyle as mentioned above you can get an idea of whether or not you may be lacking in this critical nutrient. The next best thing to dietary vitamin K2 is a vitamin K2 supplement. MK-7 is the form you’ll want to look for in supplements, because in a supplement form the MK-4 products are actually synthetic. They are not derived from natural food products containing MK-4. The MK-7– long-chain, natural bacterial-derived vitamin K2– is from a fermentation process, which offers a number of health advantages:

  • It stays in your body longer
  • It has a longer half-life, which means you can just take it once a day in very convenient dosing

Finally, remember to always take your vitamin K supplement with fat since it is fat-soluble and won’t be absorbed without it.
