People who consumed 200 to 300 milligrams of caffeine a day were less likely to develop coronary heart disease, type 2 diabetes or stroke.

There are certain studies that coffee lovers, well, love.

This is one of them: Drinking several cups of caffeinated coffee or tea a day may protect against Type 2 diabetes, coronary heart disease and stroke.

The findings, published Tuesday in the Journal of Clinical Endocrinology & Metabolism, add to existing research suggesting that daily coffee drinkers have better heart health than nondrinkers — provided they don’t drink too much caffeine.
