You should drink no more than 4 cups of coffee a day

Aside from keeping you awake and energetic throughout the day, drinking coffee brings you many other health benefits. Researchers find that drinking coffee can help you to lower the risk of heart failure, though further studies are needed to understand what processes may cause this to happen. Other studies show that by drinking coffee, you are less likely to develop depression or Alzheimer's disease. Most importantly, drinking coffee can reduce your risk of getting cancer. The reason for that is because caffeic acid and chlorogenic acid - the two chemicals found in coffee inflammation and exhibit antioxidant capacity. They increase the level of antioxidants in the body and decrease oxidative stress within cells, which can slow down and even prevent cell damage.

However, "more is more" doesn't apply to drinking coffee, as there are also lots of disadvantages to drinking too much coffee. The most common bad effect that people know about drinking too much coffee is, of course, sleep trouble. Following sleep trouble, you might have to face other bad effects including jitteriness, anxiety, and heart pounding. According to studies, you should drink no more than 4 cups a day. This is a safe number, though it is thought to be ideal if you consume 2 - 3 cups a day.
