Make the calcium connection
1988
Foster, W.
Calcium is an essential nutrient required to build strong bones and teeth, and to allow for proper blood clotting, muscle contractions, and nervous system function. Growing children need 2 to 4 times as much calcium per kilogram of body weight as adults. Recommended Dietary Allowances for calcium are shown for persons of all ages. Dairy products are the primary and best-absorbed sources of dietary calcium. To increase calcium absorption from foods, persons should be sure to get enough vitamin D and avoid too much protein, fiber, and alcohol. Suggestions are given to help school food service personnel increase the calcium provided by school lunches.
