Considering that heart disease is the number one killer and that dark chocolate has been shown to substantially reduce risk of cardiovascular disease, I believe regular chocolate consumption can be a good thing. Always choose above 70-percent cacao and select your brand wisely so as to keep your cadmium, lead, and sugar low while maximizing the antioxidant and flavonol benefits.
A German study of the diets of more than 19,000 people found that eating chocolate may help lower blood pressure, and in turn, cardiovascular disease risk. A widespread analysis of numerous studies on the topic conducted by Australian researchers also found limited but noticeable blood pressure benefits from eating the superfood. Again, very few studies pinpoint the exact amount of dark chocolate or flavonoids needed to get this effect, and more scientific study is needed.
Cacao contains more than 300 compounds, including protein, fat, carbohydrates, fiber, iron, zinc, copper, calcium and magnesium, according to a Natural News article. “Magnesium helps to build strong bones and is a muscle relaxant associated with feelings of calmness,” the report adds. “Cacao is also high in sulfur, which helps form strong nails and hair.”
A study published in International Journal of Cardiology had subjects either consume a daily dose of flavonoid-rich dark chocolate or non-flavonoid white chocolate for two weeks. The results showed that flavonoid-rich dark chocolate intake significantly improved heart circulation in healthy adults. On the other hand, white chocolate with zero flavonoids to brag about had no positive health effects on the subjects. (6)
The FRAP assay of Benzie and Strain  was used with minor modifications that allowed quantification of most water- and fat-soluble antioxidants [16,17]. A Technicon RA 1000 system (Technicon instruments corporation, New York, USA) was used for the measurements of absorption changes that appear when the TPTZ-Fe3+ complex reduces to the TPTZ-Fe2+ form in the presence of antioxidants. An intense blue color with absorption maximum at 593 nm develops. The measurements were performed at 600 nm after 4 min incubation. An aqueous solution of 500 μmol/L FeSO4 × 7 H2O was used for calibration of the instrument. Validation of the assay is described in Halvorsen et al. 2002 . Briefly, the within-day repeatability measured as relative standard deviation (RSD) in standard solutions ranged from 0.4% to 6%. The between-day repeatability was < 3%. The variation in the values for replicate food items obtained from the same source were typically between 3 and 10 RSD%.
One of the effects of sugar on the body is that it could make your depression worse, according to research. “I like to tell my patients there’s a truth to the saying, ‘You are what you eat,’” says psychologist Deborah Serani, PsyD, award-winning author of Depression in Later Life. “High levels of sugar in the form of simple carbohydrates leads to spikes and crashes in glucose levels, which can worsen mood, increase irritability, agitation, irregular sleeping, and increase inflammation.” Instead, munch on lean protein, complex carbs, and foods with omega-3s, folate, and B vitamins.
Of the over 4 million cancer patients being treated in the U.S. today, almost none are offered any scientifically guided nutrition therapy other than being told to "just eat good foods." Many cancer patients would have a major improvement in their conditions if they controlled the supply of cancer's preferred fuel: GLUCOSE. By slowing the cancer's growth, patients make it possible for their immune systems to catch up to the disease. Controlling one's blood-glucose levels through diet, exercise, supplements, meditation and prescription drugs - when necessary - can be one of the most crucial components to a cancer treatment program. The saying "Sugar feeds cancer" is simple. The explanation is a little more involved.
Currently, there are no government guidelines for consumers on how many antioxidants to consume and what kind of antioxidants to consume in their daily diet, as is the case with vitamins and minerals. A major barrier to such guidelines is a lack of consensus among nutrition researchers on uniform antioxidant measurements. Scientists will soon attempt to develop such a consensus at the First International Congress on Antioxidant Methods, held June 16-18 at the Caribe Royale Hotel and Conference Center in Orlando, Fla., with the ultimate goal of developing better nutritional data for consumers. ACS is the principal sponsor of the meeting.

Dark chocolate is high in calories (150-170 calories per ounce) and can contribute to weight gain if eaten in excess. However, chocolate, like nuts can induce satiety, so the longer term implications for weight control are not clear. It also contains a moderate amount of saturated fat, which can negatively affect blood lipid levels, though its heart-protective effects from flavanols appear to outweigh the risk. Choosing dark chocolate and eating modest quantities may offer the greatest health benefits.

To date, studies have confirmed that chronic inflammation contribute to factors that increase your risk of developing cancer, including DNA mutations and cancer cell growth. Research has confirmed that the antioxidants in dark chocolate have a strong ability to fight the DNA damage that could lead to cancer development, as well as reduce certain inflammation enzymes that could encourage its growth (12).
The cocoa butter found in dark chocolate contains equal amounts of oleic acid (a heart-healthy monounsaturated fat also found in olive oil), stearic and palmitic acids. It’s true that stearic and palmitic acids are forms of saturated fat, but research shows that stearic acid appears to have a neutral effect on cholesterol, which means it doesn’t raise it or lower it. The palmitic acid in dark chocolate can increase cholesterol levels, but thankfully it only makes up about a small portion of the fat in dark chocolate — plus dark chocolate has a lot of great plant nutrients that make up for palmitic acid.
Dark chocolate may have something in common with carrots: Researchers from the University of Reading in England tested the eyesight of 30 healthy adults, 18 to 25 years old, after they ate white and dark chocolates. The subjects performed better on vision tests after eating the dark chocolate. It could be that the flavanols in dark chocolate, which improve blood flow to the brain, improve blood flow to the retina as well — and white chocolate doesn’t have nearly the same amount of flavanols as dark chocolate.
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!
It’s helpful to understand a little about how sugar is used by the brain. The carbohydrates you eat, including sugars, are broken down into glucose. Your brain needs glucose to function properly. Unfortunately, many people eat much more sugar than they need. According to the Department of Health and Human Services, the average American eats the equivalent of about 42 teaspoons of sugar a day. That added sugar comes from various sources, such as table sugar, baked goods, and sugary drinks.
