“Most of this research has focused on the role of a substance called epicatechin, a plant nutrient found in cocoa. Dark chocolate is generally rich in epicatechin, though levels vary, depending on how the sweet was produced.”
Levels of epicatechin tend to be much lower in milk chocolate, which contains little cocoa, and white chocolate contains little or none of the nutrient. (Fine by me, since I do NOT consider any white food to be chocolate.)
“Epicatechin is known to prompt cells that line blood vessels to release extra nitric oxide, a substance that has multiple effects in the body. Nitric oxide slightly increases vasodilation, or a widening of the veins and arteries, improving blood flow and cardiac function. It also gooses muscle cells to take in more blood sugar, providing them with more energy, and it enhances the passage of oxygen into cells.”
“. . . scientists do not yet know the ideal dosage of dark chocolate for athletes, and that more than 40 grams is unlikely to be helpful” (those of us who are NOT athletes can eat more).
