Soy’s naturally occurring phytoestrogens are a potential alternative to HRT.

The amount of soy protein that must be consumed in order to experience positive effects of menopausal treatment is disputed, but the average recommended amount is between 20 and 30 grams per day.

Soy protein in the diet might help reduce the risk of heart disease by more than 20%.   As little as 25 grams of soy protein in a day can significantly reduce blood cholesterol and heart disease.   A diet high in soy protein can reduce LDL cholesterol by as much as 12.9% which translates to a reduction in the risk of heart disease by more than 20%.

A recent study showed that soy protein-based sports nutrition supplements promoted and enhanced performance and strength in athletes, improved Iron status and maintained muscle growth, without increasing body fat.



Soy protein with isoflavones compares favorably with traditional HRT for effects on cardiovascular disease and risk factors.

Soy protein with isoflavones do not appear to increase breast and endometrial cancer risk and may be protective.

Soy protein with isoflavones is less effective than HRT for reducing menopausal symptoms, preventing bone loss and genito-urinary tract symptoms.

Neither purified isoflavones nor soy proteins without isoflavones appear to have the same beneficial effects for cardiovascular disease and menopausal symptoms, as does HRT.

Uncertainty continues about the safety and efficacy of soy for bone density and cancer.
