Benefits of Soy Protein for Breast Growth

Protein from legumes, such as beans, provides a healthy alternative to animal protein. Soybeans are commonly grown legumes that are a staple in the Asian diet, and are becoming more common in Western kitchens. Soybeans are processed into milk, tofu, meat substitutes and flour. Soybeans are high in vitamins and fiber, as well as protein. Soybeans contain a plant-derived estrogen called phytoestrogen. Estrogen is a female hormone necessary for breast development; increasing soy consumption is shown to enhance breast growth.

Soy foods are low in fat and cholesterol, and high in fiber, Vitamin B and calcium. The Food and Drug Administration states that eating soy foods may lower the risk of heart disease by lowering cholesterol. Soy foods are also a great source of Omega 3 fatty acids. Omega 3, according to studies from the 1980s, is thought to prevent heart disease and reduce the risk of Alzheimer's disease. Soy milk contains phytoestrogen, which mimics the female sex hormone estrogen. Scientists believe that the estrogen in soy foods may help prevent breast cancer and osteoporosis and relieve symptoms of menopause. Estrogen is necessary for the development of female sex characteristics and the reproductive system, including breast development.

Estrogen from soy, if taken in high doses, works in a manner similar to human estrogen; it will increase breast size. A study published by Cornell University in 2001 notes that there was measurable growth in the milk ducts of women who took soy supplements. More tests are needed to validate the benefits of soy in breast growth.
