Can soymilk lower my cholesterol, and is it safe to give it to my 5-year-old daughter instead of regular milk?

There is growing evidence that soy protein might help lower blood cholesterol levels in some individuals, says Dr. William Wong, a scientist studying the benefits of soy at the USDA/ARS Children's Nutrition Research Center at Baylor College of Medicine in Houston. 

Soymilk, made by pressing the liquid from ground soybeans, is rich in soy protein.  On the other hand, soy sauce, a high-sodium condiment made from fermented soybeans, is generally used only as a flavoring.  Because it is used in such small amounts, soy sauce provides little, if any, cholesterol-lowering benefits.

Before replacing cow's milk with soymilk in your daughter's diet, read the labels carefully.  Soymilk is not naturally high in calcium, which your daughter needs to build strong bones.  Look for a soymilk fortified with at least 30 percent of the daily value of calcium, which is the same amount of calcium in cow's milk.  Soymilks also vary in protein and fat content.  A good choice contains at least 6 to 8 grams of protein per cup and less than 3 percent fat.  Many soymilks are also fortified with vitamins D and A.

Although soy may help lower your cholesterol, remember it is no panacea.  Eating a well-balanced, low-fat diet based on the USDA Food Guide Pyramid, exercising, and maintaining your weight are still the most important things you can do for your overall health.
