There seems to be a constant debate about whether coffee brings more health benefits or more harm. How much coffee should I drink every day?

1 cup of coffee

Benefits:

Greek researchers studied 485 people over the age of 65 and found that one cup of coffee a day can keep arteries healthy and stabilize blood pressure. A survey of 600 volunteers at the University of Bristow in the UK also showed that one cup of coffee a day can boost brainpower.

Disadvantages:

It takes eight hours for caffeine to be fully excreted, so if you drink coffee after 3 or 4 p.m., you are prone to sleep disorders.

2 cups of coffee

Benefits:

A study by the University of Florida found that 200 milligrams of caffeine, equivalent to two cups of coffee, can prevent memory loss and Alzheimer's disease. Research in the International Journal of Sports Medicine also shows that drinking coffee 30 minutes before exercise can help improve performance.

Disadvantages:

If you are pregnant, your coffee intake should be less than two cups, otherwise it will increase the risk of miscarriage.
