Various types of chocolate were analyzed, from milk chocolate to dark chocolate and baking cocoa. The variation of antioxidant content in chocolate ranged from 0.23 in white chocolate to 14.98 mmol/100 g in one individual dark chocolate sample. Mean antioxidant contents increased with increasing content of cocoa in the chocolate product (Pearson correlation r = 0.927, p < 0.001). Chocolate products with cocoa contents of 24-30%, 40-65% and 70-99% had mean antioxidant contents of 1.8, 7.2 and 10.9 mmol/100 g, respectively.
Prevent diabetes – Dark chocolate reduces insulin resistance. In a small Italian study, participants who ate a candy bar’s worth of dark chocolate once a day for 15 days saw their potential for insulin resistance drop by nearly half. The flavonoids, which are the antioxidants in dark chocolate, create a gas called nitric oxide that helps control insulin sensitivity.
Why should I care about antioxidants? The short answers is because healthy pros say so; the longer one is because the higher antioxidant foods and products we welcome into our lives, the more able our bodies are able to stop or delay the damaging of cells. Oxidants — the opposite of anitoxidants –are free radicals naturally produced by our bodies to help fight off viruses and other health-inhibiting invaders. They also occur in our environment via air pollution, smoke, alcohol etc. which can cause an unhealthy buildup in our systems. Oxidant overload can lead to accelerated aging, weakened immunity, and cellular damage linked to disease among other major health hurdles down the line. On the logical flip-side, inviting more antioxidants into our bodies directly combats these adverse effects.
The average American consumes roughly 12 pounds of chocolate each year, and over $75 billion is spent annually worldwide on chocolate. (1) There is a lot of chocolate eating going on regularly, which is why I want to help you make the smart, healthy choice. That way you can have your chocolate without guilt and with health benefits of dark chocolate to boot!
But how much salt should you eat each day? While every guideline and health authority would have you eating no more than one teaspoonful of salt per day, evidence from studies published in the medical literature suggests that most people should eat around 1½ to 2 teaspoons of salt per day. More salt may be needed if you are an avid exerciser and lose salt in sweat or out the urine via coffee intake.
It’s not exactly agreed upon who first “discovered” antioxidants. Antioxidants have been dated in medical literature to the early 19th and 20th centuries, but researchers and health experts have been discussing them for much longer. Each antioxidant has its own unique history of discovery. Some, such as vitamin C and vitamin E, were first researched by doctors, such as Henry A. Mattill during the 1920s–1950s, used to explain why animals fed whole foods lived longer and remained healthier. (2)
Along the way, the benefits of dark chocolate have pushed its popularity. You’ve probably seen dark chocolate listed among “must-eat healthy foods” in compilations written by various nutrition experts. Yet depending on how it’s made, dark chocolate also can be high in calories, fat, sugar, and preservatives. So, what’s the real deal? Is dark chocolate healthy?

No introductions are needed for this highly treasured food that dates back to 2000 BC. At that time, the Maya from Central America, the first connoisseurs of chocolate, drank it as a bitter fermented beverage mixed with spices or wine. Today, the long rows of chocolate squares sitting neatly on your store shelves are the end result of many steps that begin as a cacao pod, larger than the size of your hand. Seeds (or beans) are extracted from the pod and fermented, dried, and roasted into what we recognize as cocoa beans. The shells of the bean are then separated from the meat, or cocoa nibs. The nibs are ground into a liquid called chocolate liquor, and separated from the fatty portion, or cocoa butter. The liquor is further refined to produce the cocoa solids and chocolate that we eat. After removing the nibs, the cocoa bean is ground into cocoa powder that is used in baking or beverages.

The category includes 52 products, including European, Scandinavian and American products. The variation in antioxidant content in dinner and dessert products for infants varies from 0.02 to 1.25 mmol/100 g. Interestingly, human breast milk (49 samples from Norwegian mothers) has a mean content of 2.0 mmol/100 g. In addition, the category includes two Norwegian dog rose products for infants with antioxidant contents of 6.7 and 18.5 mmol/100 g.
But there are lesser-known reasons you should indulge in the (bitter)sweet stuff. Dark chocolate has been scientifically proven to keep your brain sharp, your ticker ticking and your skin shielded from the sun’s harmful rays (yes, really). Dark chocolate can be the key to beating that midday slump, accoriding to a new study from Northern Arizona University found.
My kids typically make good food choices on their own and have become rather adventurous eaters since they aren’t restricted or expected to only consume chicken fingers or hamburgers when we aren’t at home. For instance, my two year old loves broccoli, olives, sardines and other healthy foods. Make the good foods readily available and make the unhealthy ones few and far between…
What Does It All Mean?The antioxidant powerhouses aren’t the ones most people think of. It also means that making little tweaks to the foods we already eat can impact our health in a major way. A daily dose of all-the-kale-you-can-eat will help undo some damaging influence of free radicals, but a casual dash of cinnamon across your fave breakfast bowl will do so much more.
For a report published in the Journal of Agricultural and Food Chemistry in 2004, scientists from the U.S. Department of Agriculture (USDA) performed what is considered to be the most comprehensive analysis of the antioxidant content of commonly consumed foods. The USDA scientists ranked these foods according to their total antioxidant capacity, which is a measure of the antioxidants' ability to neutralize free radicals.
Hence, cancer therapies should attempt to regulate blood-glucose levels through diet, supplements, exercise, medication when necessary, gradual weight loss and stress reduction. Since cancer cells derive most of their energy from anaerobic glycolysis, the goal is not to eliminate sugars or carbohydrates entirely from the diet but rather to control blood-glucose within a narrow range to help starve the cancer cells and boost immune function.
An ongoing 40-year study on the effects of chocolate on cognitive function was recently finished. The study used data from the beginning of the study and compared it through cross-sectional study. This might not mean that chocolate makes people smarter—perhaps smart people happen to eat chocolate. Regardless, the study also concluded that all the types of intelligence measured previously were increased by chocolate consumption—along with spoken word recall. 
Such observational studies don't prove that chocolate is responsible for these benefits. However, the consistent and repeated positive results in studies done on cocoa indicate that chocolate does have a positive effect on the cardiovascular system. Chocolate has had such a profound effect on so many systems in the human body some authorities are unsure whether to call it a food or a drug.
If you’re like me, you love to eat chocolate. But not just any chocolate — I eat the varieties that are often referred to as “superfoods.” I’m talking about dark chocolate and cacoa nibs, which are both truly healthy forms of chocolate if you pick the right products. You’re probably thinking how is dark chocolate good for you, and in general, is chocolate good for you? Well, I’m about to tell you all about dark chocolate and how the benefits of dark chocolate are definitely for real.
With this study we present a comprehensive survey of the total antioxidant capacity in foods. Earlier small-scale studies from other laboratories have included from a few up to a few hundred samples [20-22,29-31], and in 2007 the U.S. Department of Agriculture presented the Oxygen Radical Absorbance Capacity (ORAC) of Selected Foods report including 277 food samples [23]. These studies have been done using different antioxidant assays for measuring antioxidant capacity making it difficult to compare whole lists of foods, products and product categories. Still, a food that has a high total antioxidant capacity using one antioxidant assay will most likely also be high using another assay [20-22]. Consequently, the exact value will be different but the ranking of the products will be mainly the same whichever assay is used. In the present extensive study, the same validated method has been used on all samples, resulting in comparable measures, thus enabling us to present a complete picture of the relative antioxidant potential of the samples.

Glutathione is considered the body’s most important antioxidant because it’s found within the cells and helps boost activities of other antioxidants or vitamins. Glutathione is a peptide consisting of three key amino acids that plays several vital roles in the body, including helping with protein use, creation of enzymes, detoxification, digestion of fats and destruction of cancer cells.
The research is piling up that soda is bad for your brain, as are other added sugars. An animal study from Oregon State University found that a high-sugar diet led to cognitive impairments, including memory problems. And a UK study recently found the “tipping point” at which blood sugar negatively affects the progression of Alzheimer’s. “Excess sugar is well known to be bad for us when it comes to diabetes and obesity, but this potential link with Alzheimer’s disease is yet another reason that we should be controlling our sugar intake in our diets,” study author Dr. Omar Kassaar of the University of Bath said in a press release.
