What are Soya Isoflavones?

Isoflavones are a group of naturally-occurring chemicals that mimic the overall shape of oestrogen in the body. In many ways they can be thought of as plant-based oestrogen alternatives. It is for this reason that they are sometimes known as “phytoeostrogens” by scientists – with “phyto” meaning “plant”. When consumed, many experts believe that by binding to oestrogen receptors in the body, they perform a similar role to standard oestrogen.

Isoflavones are found in a range of different plants, including red clover and black cohosh, both of which have been used as traditional remedies for generations. Possibly the most popular plant-based source of these, however, is soya. 

It has long been noted that individuals in the East, where soya and soya-based foods like tofu are common dietary constituents, tend to suffer fewer menopause symptoms. Further investigations have revealed the exceptionally high level of isoflavones found in soya. These days, such is the popularity of soya isoflavones, it is no longer necessary to eat large volumes of soya. Instead, the same benefits can be experienced from specially-made supplements, where simply swallowing a couple of capsules provides a generous volume of isoflavones. 

Isoflavones show tremendous potential to fight disease on several fronts. They have been shown to help prevent the buildup of arterial plaque, which reduces the risk of coronary heart disease and stroke. Isoflavones may help reduce breast cancer by blocking the cancer-causing effects of human estrogen. They may also prevent prostate cancer by hindering cell growth. Isoflavones can fight osteoporosis by stimulating bone formation and inhibiting bone resorption. They may even relieve some menopausal symptoms as well.

Soy isoflavones have antioxidant properties which protect the cardiovascular system from oxidation of LDL (the bad) cholesterol. Oxidized LDL cholesterol accumulates in the arteries as patches of fatty buildup which blocks the flow of blood, resulting in atherosclerosis. Genistein inhibits the growth of cells that form this artery clogging plaque. Arteries damaged by atherosclerosis usually form blood clots. This can lead to a heart attack if the clot goes to the heart, or a stroke if it goes to the brain.

What Are the Health Benefits of Soy Isoflavones for Women?

Improves Symptoms of Polycystic Ovary Syndrome

Women with polycystic ovary syndrome (PCOS) have a hormonal imbalance that causes a host of distressing symptoms, including weight gain, insulin resistance, thinning hair and irregular periods. Treating PCOS is a specialized process that addresses individual concerns, such as medication to control blood sugar. Dietary changes, like limiting carbohydrate intake, tend to improve PCOS symptoms as well.
