14. Diet Soda
Many people gave up regular soda in favor of diet soda. Diet sodas have zero calories, so people naturally assume that they are healthy, which is not the case. Researchers have found that artificially sweetened drinks increase a person’s chance of having a stroke. Research in the journal Stroke, which is published by the American Heart Association, found that drinking soda just once a day increases the risk of stroke. Substitute your soda for water, and you will cut your heart attack risk. Research published in the American Journal of Epidemiology found that participants who drank five glasses of water each day lowered their risk of heart attack by nearly half.
