Chemicals such as lignans and chlorogenic acid may reduce inflammation and help control blood sugar, both of which could help reduce the risk of heart disease. 


Some scientific research suggests that coffee’s unique chemical composition may include health-supporting elements, including (but hardly limited to) caffeine.
