Children and teenagers need more calcium than adults do because your bodies are still growing. Like we said earlier, your body has more calcium in it than any other mineral.

Iron works with protein to help the red blood cells make hemoglobin.
Hemoglobin is needed to help carry oxygen to all parts of your body. That oxygen gives you energy to play, run, and do work. Iron is very necessary in our diets. If you do not have enough you may feel tired and weak because your blood probably isn't carrying enough oxygen to other parts of your body. Sources of Iron include liver, poultry, lean meats, eggs, green leafy vegetables, bread, cereals, prunes, raisins, and dried apricots.
