The more coffee you consume, the less your risk for liver cancer. According to a study published in BMJ Open, just one cup of coffee daily reduces the likelihood of developing hepatocellular cancer by 20 percent. Two cups a day led to a 35 percent reduction, while five cups per day led to a 50 percent reduction. "We're not suggesting that everyone should start drinking five cups of coffee a day," says lead author Oliver Kennedy. "There needs to be more investigation into the potential harms of high coffee caffeine intake." Hepatocellular cancer is the second-leading cause of death from cancer globally.
