The Silent Inflammation That Afflicts 3 Out of 4 Americans

carotenoids as natural astaxanthin
July 12, 2011

By Dr. Mercola
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.

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 E and 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:
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.
  2. 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.
  3. Carpal tunnel syndrome (CTS), aka "repetitive stress injury": CTS is a debilitating disease of the wrist that manifests as numbness, pain, and even paralysis.
  4. 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.
  5. Rheumatoid arthritis: RA is a painful and disfiguring autoimmune disorder.
  6. 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.]
  7. Post-exercise joint soreness: Can astaxanthin be of benefit to you if you are healthy and have no disease or affliction?
  8. 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 it naturally 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.

7 Top "Healthy" Foods to Avoid

Farmed Fish
July 01, 2015

By Dr. Mercola
In a global survey of more than 27,000 people, 26 percent reported that confusion about which foods are healthy was a major barrier to eating right.1That confusion is only compounded upon because many of the "official" dietary recommendations are contrary to optimal health.
There is no one-size-fits-all diet that benefits everyone, but there are certain principles that will help most people thrive. You want to be centering your diet on whole foods, for starters – those that come from nature, are minimally processed and, ideally, are grown locally and without synthetic chemicals.
At the same time, you want to minimize your intake of processed foods, particularly snack foods and convenience foods that have little to offer in the way of nutritional value. Such foods will add to your toxic load by way of high-fructose corn syrup, artificial colors and flavors, preservatives, and genetically modified (GM) ingredients while offering your body next to nothing in return.
Some foods do not fall neatly into these two categories, however, and may masquerade as "healthy" foods when in fact they should be avoided. Below you'll find examples of some of these "healthy" foods that could be sabotaging your healthy-eating intentions.

7 Top 'Healthy' Foods to Avoid

1. Yogurt
Yogurt can be incredibly healthy, rich in high-quality protein, beneficial probiotics, calcium, B vitamins, and even cancer-fighting conjugated linoleic acid (CLA). But the key words are "can be."
Most yogurts sold in US grocery stores resemble more of a dessert than a health food. One six-ounce container of Yoplait yogurt may contain 26 grams of sugar (for the red raspberry flavor, for example).2
The negative effects of the sugar far outweigh any marginal benefits of the minimal beneficial bacteria they have. Remember, the most important step in building healthy gut flora is avoiding sugar, as that will cause disease-causing microbes to crowd out your beneficial flora.
Many other yogurts contain artificial colors, artificial sweeteners, artificial flavors, and additives, yet masquerade as health food. Mark A. Kastel, co-director of The Cornucopia Institute, which released the Yogurt Report last year, said:3
"What is most egregious about our findings is the marketing employed by many of the largest agribusinesses selling junk food masquerading as health food, mostly aimed at moms, who are hoping to provide their children an alternative, a more nutritious snack.
In some cases, they might as well be serving their children soda pop or a candy bar with a glass of milk on the side."
If you want to know which commercial yogurts are healthy and which are not, refer to The Cornucopia Institute's Yogurt Report. Their investigation found many products being sold as yogurt do not even meet the standards for real yogurt. The report also includes a comparative cost analysis of commercial yogurt brands.
The top-rated yogurts are generally VAT pasteurized at relatively low temperatures and are made from raw milk rather than previously pasteurized milk.
The good news is many organic yogurts are actually less expensive, on a price-per-ounce basis, than conventional, heavily processed yogurts (although some of the organic brands of yogurt actually contained some of the highest amounts of sugar).
Your absolute best bet when it comes to yogurt, however, is to make your own using a starter culture and raw grass-fed milk.
2. Fish
Fish has always been the best source for the animal-based omega-3 fats EPA and DHA, but as levels of pollution have increased, you have to be very choosey about which types of seafood you decide to eat.
If you're not careful, the toxic effects from the pollutants in the fish will outweigh the benefits of the omega-3 fats. About half of the world's seafood comes from fish farms, including in the US, and this is expected to increase. At first glance, farmed fish may seem like a good idea to help protect wild seafood populations from overfishing.
In reality, however, the industry is plagued with many of the same problems surrounding land-based concentrated animal feeding operations (CAFOs), including pollution, disease, and inferior nutritional quality.
It's getting so bad that fish farms can easily be described as "CAFOs of the sea." Many farmed fish are fed genetically modified (GM) corn and soy, which is a completely unnatural diet for marine life. Others are fed fishmeal, which is known to accumulate industrial chemicals like PCBs and dioxins.
In a global assessment of farmed salmon published in the journal Science, for instance, 13 persistent organic pollutants were found.4 Some of the most dangerous are PCBs, strongly associated with cancer, reproductive, and other health problems. PCB concentrations in farmed salmon were found to be eight times higher than in wild salmon.
Certain types of farmed fish, including farmed catfish imported from china and farmed shrimp from China, India, Malaysia, Mexico, Vietnam, Bangladesh, and Indonesia are even on the US Food and Drug Administration's (FDA) watch list for illegal drug residues, including antibiotics and anti-fungal compounds.5
Levels of critical omega-3 fats may also be reduced by about 50 percent in farmed salmon, compared to wild salmon, due to increasing amounts of grain feed.
One study published in the Journal of the American Dietetic Associationfound farmed tilapia and farmed catfish also have much lower concentrations of omega-3s and very high ratios of omega-6 fats to omega-3 fats.6
So is any fish still considered a "health food"?
Among the safest in terms of contamination, and the highest in healthyomega-3 fat, is wild-caught Alaskan and sockeye salmon. Neither is allowed to be farmed, and are therefore always wild-caught. The two designations you want to look for on the label are: "Alaskan salmon" (orwild Alaskan salmon) and "Sockeye salmon."
Canned salmon labeled "Alaskan salmon" is also a good choice and offers a less expensive alternative to salmon fillets. A general guideline is that the closer to the bottom of the food chain the fish is, the less contamination it will have accumulated, so other safer choices include smaller fish like sardines, anchovies, and herring.
Sardines, in particular, are one of the most concentrated sources of omega-3 fats, with one serving containing more than 50 percent of your recommended daily value.7
They also contain a wealth of other nutrients, from vitamin B12 and selenium to protein, calcium, and choline, making them one of the best dietary sources of animal-based omega-3s.
Finally, no matter what type of fish you're considering, look for varieties that have received the Marine Stewardship Council (MSC) certification. This certification assures that every component of the manufacturing process – from how the raw materials are harvested to how the product is manufactured – has been scrutinized by MSC and has been independently audited to ensure it meets sustainable standards.
3. Soy
Soy is touted as a healthy vegetarian source of protein, but its phytoestrogens (or isoflavones) can mimic the effects of the female hormone estrogen. These phytoestrogens have been found to have adverse effects on various human tissues, as they produce a variety of mild hormonal actions within the human body.
An increased risk of breast cancer is another potential hazard, especially if you're exposed to high amounts of estrogen-mimicking compounds from birth.
Unfermented soy also contains natural toxins known as "anti-nutrients," along with additional anti-nutritional factors such as saponins, soyatoxin, protease inhibitors, and oxalates. Some of these factors interfere with the enzymes you need to digest protein.
While a small amount of anti-nutrients would not likely cause a problem, the amount of soy that many Americans in products like tofu, soy milk, soy oil, soy protein powder, and soybeans, can be extremely high. Further, one of the worst problems with soy comes from the fact that 94 percent of soybeans grown in the US are genetically modified.8 One of the best studies ever done to document the dangers of GM foods found that overall, inflammation levels were 2.6 times higher in GM-fed pigs than those fed a non-GM diet, and male pigs fared worse than the females.
If you eat Roundup Ready soy, one common GM variety that's engineered to withstand the herbicide Roundup, you'll be exposed to its active ingredient, glyphosate. The International Agency for Research on Cancer (IARC), which is the research arm of the World Health Organization (WHO), determined glyphosate to be a "probable carcinogen" (Class 2A). This was based on "limited evidence" showing that the popular weed killer can cause non-Hodgkin's lymphoma and lung cancer in humans, along with "convincing evidence" it can also cause cancer in animals.
Glyphosate and glyphosate formulations have also been shown to induce DNA and chromosomal damage in mammals, as well as human and animal cells in vitro. Even if you opt for organically grown soy, I still don't recommend consuming it, however, unless it's in fermented form. For centuries, Asian people have been consuming fermented soy products such as natto, tempeh, and traditionally made soy sauce -- and enjoying the health benefits. Fermented soy does not wreak havoc on your body like unfermented soy products do, but unfortunately, most soy sold in the US market is the unfermented, processed variety.
4. Agave
Most agave nectar or syrup is nothing more than a laboratory-generated super-condensed fructose syrup, devoid of virtually all nutrient value. This so-called "healthy" sweetener is mostly fructose and is so highly processed and refined that it bears no resemblance to the plant for which it's named. Depending on how it's processed, it may contain anywhere from 55 percent to 90 percent fructose. High-fructose corn syrup is also about 55 percent fructose so, even in the best case, agave syrup offers no advantage.
The evidence is overwhelming that, when consumed in large quantities, fructose is among the most damaging sugars you can eat. Fructose drives up uric acid, which is a direct pathway toward hypertension, insulin resistance, diabetes, kidney, and liver disease. Fructose is, in many ways, very similar to alcohol in the damage that it can do to your body…and your liver. Unlike glucose, which can be used by virtually every cell in your body, fructose can only be metabolized by your liver, because your liver is the only organ that has the transporter for it.9
Since nearly all fructose gets shuttled to your liver, and, if you eat a typical Western-style diet, you consume high amounts of it, fructose ends up taxing and damaging your liver in the same way alcohol and other toxins do. In fact, fructose is virtually identical to alcohol with regard to the metabolic havoc it wreaks. According to Dr. Lustig, Professor of Pediatrics in the Division of Endocrinology at the University of California, fructose is a "chronic, dose-dependent liver toxin." And just like alcohol, fructose is metabolized directly into fat – not cellular energy, like glucose. A better sweetener options is stevia, a natural herb.
5. Veggie Chips
Veggie chips sound like a healthy way to satisfy your snack cravings, but they're nothing more than glorified potato chips. Most are made from corn flour or potato as a base and have only veggie powder or puree added in. Not only are most of the vitamins in veggies therefore NOT in veggie chips, but these snacks are then either fried or baked at high temperatures. When carbohydrate-rich foods like chips are cooked at high temperatures, acrylamide -- a tasteless, invisible chemical byproduct -- is formed.
Animal studies have shown that exposure to acrylamide increases the risk of several types of cancer, and the International Agency for Research on Cancer considers acrylamide a "probable human carcinogen." It has also been linked to nerve damage and other neurotoxic effects, including neurological problems in workers handling the substance. While this chemical can be formed in many foods when they're heated to a temperature above 120 degrees Celsius (248 degrees Fahrenheit), French fries and potato chips are the biggest offenders.
So whether they're laced with veggie powder or not, veggie chips are not a smart food choice. A far healthier alternative would be to chop up some fresh kale and toss it with some olive oil and natural salt, then bake it in your oven until crispy (homemade kale chips are also a favorite of "soul surfer" Bethany Hamilton).10 You can, of course, also snack on fresh veggies like carrot sticks, celery sticks, radishes, bell pepper, and even asparagus, to increase your nutrient and fiber intake while satisfying your craving for a crunchy snack.
6. Fruit Juice
The primary problem with fruit juice is that it simply contains far too much fructose to be healthy, not to mention the rarely mentioned methanol toxicity in any preserved juice. While whole fruits do contain fructose, they're also rich in fiber, antioxidants, and a vast array of health-promoting phytochemicals. Fruit juices, particularly pasteurized, commercially available fruit juices, have virtually none of these phytonutrients. The fiber in the whole fruits also plays a large role in protecting you from a rapid and exaggerated rise in blood sugar.
The fiber slows the rate at which sugar is absorbed into your bloodstream, and fruit juice will not provide such protection. According to a study published in the British Medical Journal, those who drank one or more servings of fruitjuiceeach day had a 21 percent higher risk for type 2 diabetes compared to those who ate whole fruits.11 So if you're in the mood for something fruity, eat a piece of fruit instead of drinking a glass of juice.
An alternative that can be healthy is a homemade fruit smoothie, provided it's balanced with moderate amounts of fruit, protein, and healthy fats, like this avocado super smoothie (which also contains blueberries and pineapple). Most store-bought fruit smoothies are far too high in sugar and/or fructose to be considered healthy.
7. Gluten-Free Foods
Gluten, a protein found in grains such as wheat, rye, and barley, causes the immune system to attack the intestines in people with celiac disease. But non-celiac gluten sensitivity may actually affect as many as 30 percent to 40 percent of the population, and according to Dr. Alessio Fasano at Massachusetts General Hospital, virtually all of us are affected to some degree.12 This is because we all create a substance called zonulin in the intestine in response to gluten.
Glutinous proteins, known as prolamines, can make your gut more permeable, which allows partially digested proteins to get into your bloodstream that would otherwise have been excluded, any of which can sensitize your immune system and promote inflammation, contribute to chronic disease. Once gluten sensitizes your gut, it then becomes more permeable and all manner of gut bacterial components and previously excluded dietary proteins—including casein and other dairy proteins—have direct access to your bloodstream, thereby further challenging your immune system.
Gluten may even negatively impact mood and brain health.13 Gluten also makes your gut more permeable, which allows proteins to get into your bloodstream, where they don't belong. That then sensitizes your immune system and promotes inflammation and autoimmunity. Gluten-free foods are becoming more widely available in supermarkets and restaurants, due to growing consumer demand, but while this seems like it would be a healthy transition, most gluten-free products are nothing more than refined, processed junk foods.
Some may contain gluten-free grains in their place, which if you are insulin and leptin resistant will only raise your insulin and leptin levels, which is a major driver of most chronic diseases. And many gluten-free products contain high amounts of sugar, corn syrup, and alternative forms of starch, none of which is healthy. So while I believe many people can benefit from removing gluten from their diets, stick with gluten-free whole foods as a replacement – not the processed gluten-free junk foods lining many store shelves.
As an aside, many food products bearing the gluten-free label have been found to be contaminated with sometimes high amounts of gluten. In one study, even naturally gluten-free products tested positive for gluten, courtesy of cross-contamination during processing. So if you're eating gluten-free due to celiac disease, avoiding processed gluten-free products may be even more important.
