How many cups of coffee should I drink every day? Maybe four cups of coffee is too much. How would you like your coffee?

If you drink 4 cups of coffee a day, the refreshing effect is good, even if the body does not feel uncomfortable, you may also be vaguely worried that you drink a little too much.

But maybe you don't have to worry about it now. Four cups of coffee a day can reduce your risk of melanoma by 20 percent, according to a report from Journal of the National Cancer Institute, a scientific journal of the National Cancer Society. It's still a good thing.

There may be more and more opportunities to correct the name of coffee in the future.

"when I was a student a few decades ago, coffee was associated with diseases such as high blood pressure (cardiovascular disease)." Said Dr. Robert Eckel, a professor of medicine at the University of Colorado.

A 2014 study showed that if you drink 1-5 cups of coffee a day, it actually reduces the risk of cardiovascular, neurological or suicide. But drinking too much is no good. The official advice from the medical structure is that caffeine intake should not exceed 600 milligrams a day.

So, generally speaking, 227 grams of instant coffee contains 70 milligrams of caffeine, 125 milligrams of boiled coffee, 145 milligrams of drip coffee, and 75 milligrams of cappuccino, 90 milligrams of cappuccino and 75 milligrams of latte in those espresso. Let's not have more than six cups.
