Connie, that's a question that has a lot of health professionals very concerned. Many young people substitute soft drinks for milk, and in fact, soft drink manufacturers are contracting with some schools to provide soft drink dispensers in school cafeterias. Bone density is complete in women by around the mid-20's; and by the mid-30's bones begin thinning. If young people don't get adequate calcium in their teens, there is a very real possibility that bones will not achieve optimal density, and that early osteoporosis could become widespread.
