Research has shown that caffeine is the world’s most consumed and socially acceptable psychoactive drug. It is contained in most coffee bean products and some popular tea brands. Even though it could be addictive, it has some great health benefits.
One of the benefits is that it practically adds no nutritional value on its own, so no weight gain.
Also, a study published in the U.S suggested that 3 cups of coffee a day may reduce the risk of liver cancer by 50%. Caffeine also has some positive effects on the brain as regards depression, Parkinson’s disease and some cardiovascular diseases according to some studies.
In addition, in Japan, researchers have shown that caffeine increases memory. Plus, a newer study out of Johns Hopkins University showed that a 200 mg caffeine pill helped boost memory consolidation
