If you drink alcohol this new study may make you want to slow down. According to a new study, just one alcoholic drink a day can slightly increase your risk of health problems. The study that was done based on the drinking habits in 195 countries goes against previous advice on healthy drinking. Many experts aren't too pleased with the methods used to gather the information for the study. Other studies on alcohol have said that moderate drinking, one or two a day, is safe and could reduce the risk of heart disease, stroke, or diabetes.
