Prior says that the data should prove useful for consumers seeking to include more antioxidants in their diet. But he cautions that total antioxidant capacity of the foods does not necessarily reflect their potential health benefit, which depends on how they are absorbed and utilized in the body. Researchers are still trying to better understand this process, he adds.
Studies on brain activity have provided evidence supporting the idea that overeating alters our brain’s reward system, which then further drives overeating. This same process is thought to underlie the tolerance associated with addiction. Over time, greater amounts of the substance are required to reach the same level of reward. Studies imply that overeating results in a diminished reward response and a progressively worsening addiction to low-nutrient foods rich in sugar, salt, and fat.
Dark chocolate is also called semisweet chocolate while extra dark chocolate is often considered the same as bittersweet, although the ratio of cocoa butter to solids may vary between the varieties. (14) According to the FDA, semisweet chocolate or bittersweet chocolate is a sweet chocolate that contains no less than 35 percent (by weight) of pure cocoa. (15) Semisweet and bittersweet are both commonly used in baking, and although the FDA defines them in the same way, bittersweet chocolate typically has a deeper flavor and less sweetness than semisweet chocolate. (16) Unsweetened or baker’s chocolate is usually almost 100 percent cocoa with no sweetness whatsoever.
Although some preliminary studies suggest that antioxidant supplements may help thwart disease development by reducing oxidative stress, more research is needed before such supplements can be recommended for disease prevention. In fact, the National Center for Complementary and Integrative Health states that findings from rigorous scientific studies involving a total of more than 100,000 people have largely indicated that antioxidant supplements may not reduce the risk of chronic conditions like heart disease and cancer.
Another possible allergen to watch out for in dark chocolate (even organic brands) is soy lecithin, which is commonly added as an emulsifying agent. Soy lecithin does contain trace amounts of soy proteins, and these have been found to include soy allergens. However, soy lecithin does not appear to contain sufficient soy protein residues to induce allergic reactions in the majority of soy-allergic consumers. (26)
These broccoli cousins have plenty of bitter sulforaphane as well as compounds called isothiocyanates, which detoxify cancer-causing substances in the body before they can do their dirty work. In one Dutch study, guys who ate Brussels sprouts daily for three weeks had 28 percent less genetic damage (gene damage is a root cause of cancer) than those who didn’t eat sprouts. You won’t believe the way Brussels sprouts are grown.
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.
