Health Benefits
Dark chocolate contains a high concentration of stearic acid (a saturated fatty acid with a neutral effect on cholesterol), essential minerals including magnesium, copper, potassium, manganese, and most significant, flavonoids. The latter are phytochemical plant pigments that act as natural antioxidants, neutralizing free radicals that can damage body tissue and cells. (Since dairy can interfere with the absorption of these antioxidants, only dark chocolate — not milk — offers benefits.)
Flavonoids also hinder platelet aggregation and improve blood-vessel flexibility, helping to prevent hardening of the arteries. Traditionally made (meaning minimally processed) dark chocolate actually contains more flavonoids per gram than any other food tested so far, including green tea, red wine, and blueberries. The good news doesn’t stop there: The high percentage of cocoa in dark chocolate also gives it a low glycemic index, a ranking of carbohydrates according to their effect on our blood glucose levels. This means it produces only small fluctuations in blood glucose and insulin levels (diabetics, take note).
