Currently, strong evidence shows that consumption of coffee within the moderate range (3 to 5 cups per day or up to 400 mg/d caffeine) is not associated with increased long-term health risks among healthy individuals. In fact, consistent evidence indicates that coffee consumption is associated with reduced risk of type 2 diabetes and cardiovascular disease in adults. Moreover, moderate evidence shows a protective association between caffeine intake and risk of Parkinson’s disease.
They say an optimal pattern of eating includes a broad range of foods including fruits and vegetables, whole grains, legumes, nuts and seeds, as well as fish and low-fat dairy. (Hmm, that sounds a lot like the Mediterranean diet.)
