Or other ages are lacking calcium in their diet.Children between the age of 12 and 19 years are getting far less calcium than the amount that experts suggest.

Docters believe that one reason older children are not getting enough calcium is because they choose soft drinks like coca colo instead of milk.Often young (and) adults also choose soft drinks instead of natral fruit drinks that contain calcium.
Most people can receive the calcium they need from eating or drinking milk products 3 times each day.Older boys and girls require calcium in their diet 4 times each day.
Food rich in calcium include milk,cheese and yogurt(yuger).Experts say milk products low in fat contain as much calcium as those with(which is) higher fat levels.Calcium can also be found in some green vegetables although milk products are the most common way people get calcium.
