Coffee and green tea may lower mortality risk, study finds
Researchers from Japan found that regular coffee and green tea drinkers were less likely to suffer from a host of diseases and were less likely to die from certain health complications. The large-scale study followed about 90,000 people aged between 40 and 69 for an average period of 19 years and studied the correlation between their cause of death and their intake of coffee and green tea. It found that men who claimed to drink more than five cups of green tea have a 24% less risk of dying from cerebral vascular diseases and a 45% less risk of dying from respiratory diseases. While scientists involved speculate that caffeine may be responsible for the protective effects, they could not pinpoint the exact causes.
