Lung, prostate, breast, ovarian, bladder, oral and skin cancers have been demonstrated to be suppressed by retinoic acid. (9) Another study collected numerous references demonstrating the findings of retinoic acid in protection against melanoma, hepatoma, lung cancer, breast cancer and prostate cancer. However, there’s evidence indicating that the benefits of chemicals like retinoic acid are safest when obtained from food naturally, rather than supplements.
According to the FDA, chocolates are unfortunately one of the most common sources of undeclared milk linked to consumer reactions. In addition, recent testing by the FDA found that you can’t always tell if a dark chocolate has milk just by reading the ingredient list. Many manufacturers make their dark chocolate on the same equipment that they use for milk chocolate production so traces of milk end up in the dark chocolate too. (25) If you’re concerned about milk possibly being in your dark chocolate, contact the manufacturer.
Most dark chocolates are produced on the same processing line as chocolate products containing milk. Which is why most of them have advisory labels. A recent testing of 88 bars concluded that “a high proportion of dark chocolate products contain milk at concentrations associated with allergic reactions in sensitive individuals” (see the 2017 study)
A recent study by Swedish researchers found that women who ate high amounts of chocolate — about two candy bars per week — had a 20 percent lower risk of stroke. In a similar study, British researchers also found that people who ate more chocolate were 30 percent less likely to have a stroke. However, researchers added that more study is needed to determine the exact amount and types of flavonoid-rich chocolates that would be most help lessen stroke risk.
I often hear the argument that sugar is ok in moderation and that eliminating any “food group” is dangerous. Certainly, avoiding an actual macronutrient category completely (carbohydrate, protein or fat) would be problematic, but sugar in itself is not a food group. Though sugar in some form is naturally present in many foods, by itself, it contains:

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.
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.
Fish provides powerful omega-3 fatty acids. Evidence suggests that omega-3s, particularly those coming from fish, may help prevent inflammatory diseases, such as coronary heart disease. Although all fish have some omega-3s, the stars include sardines, salmon, oysters, mackerel, tuna steak, wild rainbow trout, shark steak, albacore tuna, and herring.
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.
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.
