Glycine max commonly known as soybean is a legume native to East Asia. It was introduced to America and Europe later by 18th century. Soy was introduced to Africa from China in the late 19th century, and is now widespread across the continent. It is now a major crop in the United States, Brazil, Argentina, India, and China. In India, it is widely cultivated in Madhya Pradesh.
Soybeans contain significant amounts of phytic acid, dietary minerals and B vitamins.
Soybeans are among the richest foods in total phytoestrogens which are present primarily in the form of the isoflavones daidzein and genistein. The isoflavones in soybeans lessen menopausal symptoms such as hot flushes, insomnia, excessive sweating, headaches and mood swings without side effects associated with the conventional hormone replacement therapy. It also modulates the bone loss in estrogen-deficit, post-menopausal women.
The isoflavones such as genistein inhibit the growth of prostate tissue in patients with benign prostatic hyperplasia. They even prevent progression of latent prostate cancer to more advanced forms. Many research studies have proven the therapeutic potential of the isoflavones from soybeans in benign prostatic hypertrophy. They can even reduce the likelihood of developing prostate cancer.
