The bone-depleting effect of soda might affect women and teens more than adult men, according to MedPage Today. Women who drink an average of six servings of soda per day for just six weeks could see a notable -- between 3 and 6 percent -- drop in their bone mineral density. The decrease in bone mineral density was lower with women who drank diet soda, but even diet versions still resulted in a notable decrease. Teenagers are at an even bigger risk when drinking soda. When nine of 10 teen girls and seven of 10 teen boys already aren't eating enough calcium, they can't afford to lose calcium to the phosphoric acid in soda. Teens whose bones don't get enough calcium have a higher risk of breaks, fractures and, later in life, osteoporosis.
