There’s more good news about the main chocolate ingredient. A new study led by a doctor from Mass General Brigham says cocoa extract supplements may help prevent age-related heart disease. The study found taking cocoa extract supplements regularly for two years can improve inflammation markers. Researchers focused on cocoa extract supplements high in flavanols, which are plant-based antioxidants. The study of adults age 60 and older found those who took cocoa extract boosted levels of a protein involved in the immune system by almost seven-percent.
