Q: Is milk really the best source of calcium?
– Donna in Washington, D.C.

A: Milk is a great source of calcium, but is certainly not the best or the only source. an 8-ounce glass of milk (whether it is whole, 2% or nonfat) contains about 300 milligrams of calcium and 100IU of vitamin D (a vitamin essential for calcium absorption and deposition into bone). A cup of fortified soymilk (such as 8th Continent) supplies the same amount of both calcium and vitamin D, a cup of fortified orange juice also supplies this amount, and a cup of nonfat yogurt supplies up to 488 milligrams of calcium, but no vitamin D. Sardines with the bones and cooked collard greens are also good sources of calcium. – Elizabeth Somer
