Dark Chocolate and Health

Small portions of dark chocolate can improve blood vessel flow, especially in older adults, according to studies. Studies also say that chocolate may improve blood sugar and insulin sensitivity to help reduce the risk of diabetes.

One study, published in the journal Hypertension, reported that the antioxidants found in dark chocolate could help reduce high blood pressure. It seems as if the study participants who ate chocolate also reduced their LDL "bad" cholesterol levels, and improved insulin sensitivity. Subjects in the study were limited to a small portion of dark chocolate per day.
