Researchers suggest that increasing dark chocolate consumption may help reduce the risk of developing type 2 diabetes. However, experts who were not part of the research caution that due to its observational setup, it cannot determine a cause-and-effect relationship. Moreover, they highlight that the low occurrence of diabetes in people consuming dark chocolate may result in statistical uncertainties. A new long-term US study links five weekly servings of dark chocolate to a 10% lower risk of type 2 diabetes and consuming over five servings to a 21% lower risk of developing the disease. Although the authors found no similar statistically significant association for milk chocolate consumption, they linked increased consumption of milk chocolate to excessive long-term weight gain.
