Scientists have published evidence that eating chocolate can decrease risk of heart disease. The paper analyzed and combined the results of seven separate studies, involving over 114,000 participants. Results indicated that high levels of chocolate consumption might be associated with a one third reduction in the risk of developing heart disease. The scientists also note that more studies are needed to determine whether it is actually the chocolate consumption or some other factor that they didn't analyze, that was responsible for the increased heart health. The studies looked at the consumption of dark chocolate as well as milk chocolate, chocolate drinks and other chocolate confectionaries.

Dr. Oscar Franco, senior author on the study, said:

Chocolate may be beneficial, but it should be eaten in a moderate way, not in large quantities and not in binges. If it is consumed in large quantities, any beneficial effect is going to disappear.

The analysis was published in the British Medical Journal, as an open-access study; that means you can read the paper for free (but the chocolate costs extra.)
