Answer to Question 1
Answer: The ingredients thought to be responsible for chocolate's beneficial effects are members of the flavonoid group of antioxidant phytochemicals, especially a flavonoid called epicatechin. Flavonoids reduce the buildup of cholesterol in blood vessels, blood vessel inflammation, and the platelet action that results in blood clots. They also improve blood pressure and blood lipid profiles, and reduce insulin resistance. Dark chocolate has higher levels of flavonoids than does milk chocolate.
