Coffee (and more specifically caffeine) is one of the most-tested food substances on the planet. Funnily enough, every time they test it, they find some new way that caffeine is actually good for you. It has all sorts of surprising benefits.

Obviously you shouldn’t be drinking a galloon of it a day, but in moderation, coffee is a very healthy drink. Served black it’s zero-calorie, zero-sugar, fights diabetes, lowers your weight, fights depression, prevents liver disease, and of course tastes good.

Coffee is amazing.
