Coffee’s health benefits aren’t as straightforward as they seem—here’s why

Coffee’s health benefits aren’t as straightforward as they seem—here’s why

Enlarge (credit: Florin Petrescu | Getty Images)

You’ve probably heard it before: drinking coffee is good for your health. Studies have shown that drinking a moderate amount of coffee is associated with many health benefits, including a lower risk of developing type 2 diabetes and cardiovascular disease. But while these associations have been demonstrated many times, they don’t actually prove that coffee reduces disease risk. In fact, proving that coffee is good for your health is complicated.

While it’s suggested that consuming three to five cups of coffee a day will provide optimal health benefits, it’s not quite that straightforward. Coffee is chemically complex, containing many components that can affect your health in different ways.

While caffeine is the most well-known compound in coffee, there is more to coffee than caffeine. Here are a few of the other compounds found in coffee that might affect your health.
