In July 2016 researchers from Sweden published the results of their study to assess the effect of chocolate on risk of ischaemic heart disease. A total of 67 640 individuals with no history of cardiovascular disease were included in the study. Information on chocolate consumption was collected via a food frequency questionnaire. Results showed that chocolate consumption appeared to reduce the risk of ischaemic heart disease. In addition, a review of the scientific literature was undertaken, and results showed that those consuming 3-4 servings/week of chocolate appeared to have a reduced risk of heart attacks when compared to those who consumed no chocolate.
