Bacteria in your gut break down and ferment the components in dark chocolate and cacao, turning them into absorbable anti-inflammatory compounds that benefit your health
The same cannot be said for milk chocolate, however. There’s a big difference between your average chocolate bar and what could be referred to as “therapeutic” chocolate. To understand this better, here are some definitions:
- Cacao: Refers to the plant Theobroma cacao, cultivated for its seeds, known as cacao beans or cocoa beans.
Cacao is naturally high in antioxidants and other natural compounds that are beneficial for cardiovascular health and weight management. In all, about 40 distinct health benefits3 have been linked to dark chocolate
- Cocoa: Refers to the powder made from roasted, husked, and ground cacao seeds, from which most of the fat has been removed
- Cocoa butter: The fat component of the cacao seed
- Chocolate: The solid food or candy made from a preparation of cacao seeds (typically roasted). If the cacao seeds are not roasted, then you have “raw chocolate,” which is also typically sweetened.Generally speaking, the darker the chocolate, the higher the antioxidant content. Milk chocolate has few if any health benefits, as it contains limited amounts of cacao
Knowing the meaning of these terms is important, because if you think you’re improving your health by eating typical milk chocolate candies, you’re fooling yourself.
Cocoa and cacao is typically quite bitter, and rarely fancied by self-proclaimed chocolate lovers, who are really craving the sugar added to most chocolate bars and candy.
That said, certain types of dark chocolate, as well as raw cocoa powder and cacao, are powerful superfoods, ranking among the most anti-inflammatory and antioxidant-rich foods known to mankind.
Interestingly, recent research has shed new light on the mechanism that makes cocoa powder (and dark chocolate) so beneficial for your heart and blood vessels. These benefits, it turns out, are largely dependent on the action of beneficial bacteria in your gut.
Gut Microbes Unlock Dark Chocolate’s Anti-Inflammatory Powers
While it’s known that cocoa powder is rich in potent antioxidants called polyphenols, it was thought that these molecules were poorly digested and absorbed due to their large size.
Researchers have now discovered that certain bacteria in your gut actually break down and ferment the components in dark chocolate, turning them into absorbable anti-inflammatory compounds that benefit your health.
In particular, beneficial microbes including Bifidobacterium and lactic acid bacteria like to “feast” on cocoa, according to the researchers. The microbes also break down the fiber found in cocoa powder, turning it into highly absorbable short fatty acid chains that promote satiety.
The study, which involved three cocoa powders tested in a model digestive tract, may help explain why chocolate has been found to be so good for your heart, as the anti-inflammatory compounds may reduce inflammation of cardiovascular tissue. The study’s lead author explained:
“[W]e found that the fiber is fermented and the large polyphenolic polymers are metabolized to smaller molecules, which are more easily absorbed.
These smaller polymers exhibit anti-inflammatory activity… When these compounds are absorbed by the body, they lessen the inflammation of cardiovascular tissue, reducing the long-term risk of stroke.”
Previous research7 has also shown that eating dark chocolate may help promote gut health by selectively feeding beneficial bacteria, as opposed to harmful ones. It essentially acts as a probiotic, thereby promoting a healthier gut microbiome.
Research Supports Raw Cacao for Cardiovascular Health
As mentioned, a number of previous studies have found that dark unprocessed raw cacao helps reduce your risk for cardiometabolic disorders, including:
Coronary heart disease Stroke Diabetes Metabolic syndrome Hypertension Elevated fasting glucose and triglycerides High cholesterol Abdominal obesity
One meta-analysis8 published in 2011 found that those who ate the highest amounts of dark chocolate had a 37 percent reduced risk for cardiovascular disease and a 29 percent lower risk for stroke, compared to those who consumed the least.
Small amounts of dark chocolate may also reduce your risk of heart attack because, like aspirin, it has a biochemical effect that reduces the clumping of platelets that causes blood to clot. Platelet clumping can be fatal if a clot forms and blocks a blood vessel, causing a heart attack.
Researchers also discovered that a flavonoid compound in dark chocolate called epicatechin may protect your brain after a stroke by increasing cellular signals that shield nerve cells from damage.9
A stroke is similar to a heart attack, but occurs when the blood supply to your brain becomes blocked or reduced, as opposed to blocking the blood supply to your heart.
Another way raw dark chocolate may provide cardiovascular benefit is by assisting with nitric oxide metabolism, as described by Ori Hofmekler.10 Nitric oxide protects your heart by relaxing your blood vessels and thereby lowering your blood pressure.
However, nitric oxide production produces adverse reactions and toxic metabolites, which must be neutralized by your body so they don’t result in oxidative damage to your blood vessel lining (by peroxynitrite oxidation and nitration reactions). Cocoa polyphenols protect your body from these metabolites and help counter the typical age-related decline in nitric oxide production.11
Other Health Benefits of Dark Chocolate
Besides antioxidants, chocolate also contains other potent plant compounds, including anandamide, named after the Sanskrit word for “bliss,” which is a neurotransmitter in the brain that temporarily blocks feelings of pain and anxiety.
Caffeine and theobromine in chocolate have been shown to produce higher levels of physical energy and mental alertness, and there are likely many more healthy chocolate compounds that have yet to be discovered. The following table highlights just some of the benefits conferred by the cocoa bean.12
Anti-inflammatory Anti-carcinogenic Anti-thrombotic, including improving endothelial function Lowers Alzheimer’s risk Anti-diabetic and anti-obesity Reduction in C-reactive protein Cardioprotective, including lowering blood pressure, improving lipid profile, and helping prevent atrial fibrillation Improved liver function for those with cirrhosis Neuroprotective Improves gastrointestinal flora Reduces stress hormones Reduces symptoms of glaucoma and cataracts Slows progression of periodontitis Improves exercise endurance May help extend lifespan Protects against preeclampsia in pregnant women
Determining Quality Can Be Tricky…
According to Tod Cooperman,13 president of ConsumerLab.com, which performs independent tests on health products, a recent investigation14 revealed there’s a wide range of quality when it comes to chocolate, and rarely can you tell quality by the label alone. Some brands tested did indeed have high levels of antioxidants, but others did not. Some brands had three times the concentration of flavanols compared to others, and one chocolate bar marked 85 percent flavanols actually contained less of the antioxidant than a bar labeled 72 percent.
As reported by Times,15 this kind of discrepancy is due to the fact that “the percentage is a sum of cocoa liquor, cocoa powder and cocoa butter—and cocoa butter does not contain flavanols.” The labels of some brands, however, were very accurate, including Ghirardelli and Endangered Species. Interestingly, Consumer Labs also found that dark chocolate bars may be a safer choice over raw cacao powder, as many of the latter were found to be contaminated with heavy metals.
That said, the closer your cocoa is to its natural raw state, the higher its nutritional value. To avoid contamination issues, I recommend looking for fair traded organic varieties. Ideally, your chocolate or cocoa should also be consumed raw (cacao). When selecting a chocolate bar, you can optimize its nutritional value by looking for higher cacao and lower sugar content.
What to Look for on the Label
In general, the darker the chocolate, the higher the cacao content. However, cacao is fairly bitter, and the higher the percentage cacao, the more bitter it is. The flavanols are what make the chocolate bitter, so manufacturers often remove them. But, it’s the flavanols that are responsible for many of chocolate’s health benefits. To counteract the bitterness, most chocolate is sweetened, so it’s a matter of balancing nutritional benefit with palatability. So, read your labels carefully. In addition to high cacao content, you also want to evaluate each product for the following:
- Type of sweetener: Not only should you choose chocolate with low sugar content, but you should also look at what form of sugar it contains. Honey is sometimes used to sweeten raw chocolate products, which is a good choice (in moderation). If you can find chocolate sweetened with Stevia or Luo Han, that would be preferable to cane sugar, fructose, or high fructose corn syrup. Strictly avoid any product containing artificial sweeteners.
Fructose will reverse some of the positive benefits of chocolate, as it breaks down into a variety of harmful waste products, one of which is uric acid. Uric acid drives up your blood pressure by inhibiting the production of nitric oxide in your blood vessels, which helps your vessels maintain their elasticity. So, excess fructose can lead to elevated blood pressure, as a result of nitric oxide suppression. It also promotes insulin resistance, which is at the heart of virtually all chronic disease.
- Genetically engineered cocoa beans: Select chocolate products that are certified organic so that you be sure they aren’t genetically engineered (GE). Most chocolate today (even dark chocolate) is GE, unfortunately.16 Also opt for fair-trade products.
- Type of fat: Fat in chocolate, as long as it’s the right kind, is a good thing. It slows down the absorption of sugar, lessening the insulin spike. Ideally, the type of fat in your chocolate bar should be what is contained in the natural plant—cocoa butter. The primary fatty acid in cocoa butter is stearic acid, which is the only saturated fat that favorably affects HDL, without adversely affecting LDL. Coconut oil would be the next best fat in chocolate. Make sure you avoid soybean oil (and any other form of soy), and other vegetable oils and trans fats.
Using Chocolate as a Therapeutic Tool
To learn more about the health benefits of high quality chocolate, please listen to the following interview with Dr. Beatrice Golomb, in which she also discusses how to determine your ideal therapeutic dose. In general, it seems preferable to consume smaller amounts of chocolate at more frequent intervals, much like the principle of split dosing for supplements, in order to ensure a steadier stream of nutrients in your bloodstream. According to Dr. Golomb, studies show daily chocolate consumption in divided doses (two to three times per day) is probably beneficial, as long as you aren’t going overboard in quantity, and as long as you’re eating high-quality chocolate.
How to Make a Healthier Chocolate Candy
Perhaps one of the best ways to ensure quality is to make it yourself, using high-quality ingredients. In the following video, I demonstrate how to make a healthy chocolate snack. This is a recipe I created from scratch and there are no specific measurements. You can simply use raw cocoa butter and that will give you a finished candy that melts, or you can add raw pastured butter and coconut oil, which have their own health benefits. If you use these ingredients, the candy will melt at a lower temperature and you will most likely need to keep it in the refrigerator to keep it from melting.
This week we launch Fluoride Awareness Week. We set aside an entire week dedicated to ending the practice of fluoridation.
There’s no doubt about it: fluoride should not be ingested. Even scientists from the EPA’s National Health and Environmental Effects Research Laboratory have classified fluoride as a “chemical having substantial evidence of developmental neurotoxicity.” Furthermore, according to the Centers for Disease Control and Prevention (CDC), 41 percent of American adolescents now have dental fluorosis—unattractive discoloration and mottling of the teeth that indicate overexposure to fluoride. Clearly, children are being overexposed, and their health and development put in jeopardy. Why?
The only real solution is to stop the archaic practice of water fluoridation in the first place. Fortunately, the Fluoride Action Network has a game plan to END water fluoridation worldwide. Clean pure water is a prerequisite to optimal health. Industrial chemicals, drugs, and other toxic additives really have no place in our water supplies. So, please, protect your drinking water and support the fluoride-free movement by making a tax-deductible donation to the Fluoride Action Network today.

Together, Let’s Help FAN Get to the Finish Line
This is the week we can get FAN the funding it deserves. I have found few NGOs as effective, and none as efficient, as FAN. Its small team has led the charge to end fluoridation and will continue to do so with our help!
So I am stepping up with the challenge. For the fourth year in a row, I will match the funds you give. This year, I believe a $25,000 match is the right thing to do. Please give, and all dollars received up to $25,000 will be matched by Natural Health Research Foundation, which I founded.
On Sunday, December 14th at 5pm (EST), the entire Fluoride Action Network team will be featured on this month’s International Fluoride Free Teleconference. The call is free and will provide a year-in-review of the fluoride issue, as well as provide an opportunity for supporters to ask the FAN team questions. So please register today to interact with fellow campaigners from around the world and have your questions about fluoride answered by the experts.
Also please watch the documentary Professional Perspectives on Water Fluoridation from now until December 19th, that outlines the science behind fluoridation and the effects it has had on entire generations, a select panel of experts show conclusively why there is no logical or rational reason to continue fluoridating our water supply.
