Soybeans are the most widely used, least expensive, and least caloric way to get large amounts of protein. You can eat soybeans in many forms, including tofu, the beans themselves also called edamamesoy milk, miso, and soy powder. Soy foods have a lot of isoflavones, which are weak estrogen-like compounds found in plants.
Soy comes from soybeans. The beans can be processed into soy protein, which is a powder; soymilk, which is a beverage that may or may not be fortified with extra calcium from the soybeans; or soy fiber, which contains some of the fibrous parts of the bean. Soy is taken by mouth for high cholesterol, high blood pressure, and preventing diseases of the heart and blood vessels.
To eat soy or not: That's the question many U. Tofu, miso paste and other soybean-based foods are high-quality sources of protein that are low in calories and saturated fat. And studies have shown that they can help prevent cancer.
Tofu bean curd, soybean curd is produced by coagulating soy milk and forming the curds into blocks. Soy milk is made by soaking dried soybeans and then grinding, boiling and straining them. Various coagulants are used, typically salts calcium sulfate, calcium chloride, or magnesium chloride. A significant percentage of the original soybean isoflavones are lost in the production of tofu; using calcium sulfate as the coagulant has been found to maximize the retention of isoflavones.
Are soy foods safe for breast cancer survivors, including women who were treated for estrogen receptor positive breast cancer? Summary: The current consensus among health experts who study soy is that breast cancer survivors can safely eat these foods. Emerging research suggests that soy foods may decrease the likelihood of breast cancer recurrence in women with a history of the disease.
Breast cancer rates among Asian-Americans are lower than those of US whites but considerably higher than rates prevailing in Asia. It is suspected that migration to the US brings about a change in endocrine function among Asian women, although reasons for this change remain obscure. The high intake of soy in Asia and its reduced intake among Asian-Americans has been suggested to partly explain the increase of breast cancer rates in Asian-Americans.
Allison Aubrey. New research finds eating soy milk, edamame and tofu does not have harmful effects for women with breast cancer, as some have worried. In fact, for some breast cancer survivors, soy consumption was found to be tied to longer life.

Consumed in many traditional Asian populations for millennia, soya has only been a common part of the Western diet for around 60 years. Now, many of our supermarkets are full of soy milk alternatives, soy burgers and other soya-based meat replacements — not to mention traditional soy-based products like tofu, tempeh, soya milk, miso and soya sauce. In the meantime, soya has been linked to a lower risk of heart disease compared to other diets.
Studies show that a lifelong diet rich in soy foods reduces the risk of breast cancer in women. This protective effect is less dramatic for women who eat less soy or who start eating soy later in life. Soy contains protein, isoflavones and fiber, all of which provide health benefits. It was once thought that soy foods increase the risk of breast cancer.
