But that caffeine is only mechanism behind coffee’s health effects is supported by a small study of 554 Japanese adults from October that looked at coffee and green tea drinking habits in relation to the bundle of risk factors for coronary artery disease, stroke, and type 2 diabetes known together as metabolic syndrome. Only coffee — not tea — was associated with reduced risk, mostly because of dramatic reductions observed in serum triglyceride levels.
So aside from caffeine, just what are you getting in a cup, or two, or six? Thousands of mostly understudied chemicals that contribute to flavor and aroma, including plant phenols, chlorogenic acids, and quinides, all of which function as antioxidents. Diterpenoids in unfiltered coffee may raise good cholesterol and lower bad cholesterol. And, okay, there’s also ash which, to be fair, is no more healthful than you would think — though it certainly isn’t bad for you.
