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.
Seems easy enough to determine: Look at the method and determine how many participants couldn’t afford coffee. If all of them could it’s a non-variable.
Personally I wish they had referenced black tea instead. It has mental & health benefits in addition to the relevant caffeine benefit.
