Health benefits of chocolate include improved cardiovascular health and reduced risk of diabetes and stroke. These health benefits are more substantial in dark chocolate than in milk chocolate, says Mayo Clinic.
The health benefits of chocolate come from the high levels of antioxidant flavonoids present in the food, says Cleveland Clinic. Antioxidants help the body resist damage caused by free radicals, which are formed by bodily processes such as breathing, and exposure to contaminated environments. Flavanols, the main flavonoids found in chocolate, also help to promote blood flow to the brain and heart, lower blood pressure, and improve blood clotting.
