I ran across an interesting study recently in the Journal of the American Dental Association. The authors found that fruit drinks with added calcium are better for your teeth. Just about everybody knows that calcium helps build strong teeth and bones, but in this study the benefits of the added calcium were quite intriguing. Many fruit drinks are quite acidic (orange, grape, grapefruit, etc). Many studies have shown that this acid can contribute to erosion of dental enamel, an actual washing away of your tooth structure. The author's of this study found that added calcium prevents this destructive erosion. When teeth erode they literally have their calcium washed away by acidic liquids. The calcium in the drinks appears to negate this problem. Bottom line: look for calcium fortified fruit drinks whenever possible.
