Tip for lasagne lovers: 1/4 cup of ricotta cheese has more calcium than a cup of either cottage cheese or milk.
If you take more than 500 mg of calcium daily, space the pills out during the day to enhance absorption and reduce risk of constipation.
Use skim milk everyday. It has virtually no fat and as much calcium as whole milk. If it tastes too watery to you, just add a tablespoon or two of nonfat dried milk to each cup. It will then have that richer taste with additional calcium and protein.
