All about Soy

HOW DOES SOY PREVENT DISEASES?
Soybeans have fiber and produce substances called phytochemicals. Phytochemicals are special compounds produced by plants which may help prevent disease. One group of phytochemicals found in soy is called phytoestrogens. These chemicals, along with the fiber found in soy, can help reduce LDL or “bad” cholesterol thereby decreasing the risk of heart disease. Other chemicals in soy may help prevent certain types of cancer. Soy may also help lower the risk of osteoporosis by helping the body retain calcium.

IS SOY PROTEIN SPECIAL?
Yes, soybeans are the only common plant food that contains all of the essential amino acids in the amounts needed for human health. Soybeans are considered “complete proteins.”

IS REPLACING SOME OF THE ANIMAL PROTEIN THAT I EAT WITH SOY PROTEIN GOOD FOR ME?
Absolutely! Animal protein, which includes foods like meat, poultry, milk, cheese, and eggs, has saturated fat and cholesterol, whereas protein from vegetables sources like soy does not contain any saturated fat or cholesterol. By substituting animal protein with soy foods, you can gain some of the benefits that soy has to offer, and you can also lower the amount of calories and fat that you consume each day.

HOW MUCH SOY SHOULD I EAT EACH DAY?
The Food and Drug Administration recommends that you eat 25-50 grams of soy each day if you would like to lower your cholesterol and receive the other benefits that soy has to offer.
