Strawberry or chocolate milk still has less sugar than most juices and lots of protein and calcium. Getting plenty of calcium is very important during the teenage years because the bone density formed then needs to last kids for the rest of their lives.

Most teens are not getting enough calcium. The latest recommendation is to get 1300 mg per day. There are about 300 mg in a glass of milk. Ounce for ounce, yogurt has even more calcium than milk.
