BEACON TRANSCRIPT – A new study performed by researchers at the Friedman School of Nutrition Science and Policy at Tufts University found more benefits of soy foods. They discovered that soy is not only good for breast cancer survivors, but it can act as protection against the disease.
Until recently, there has been much confusion about women and soy consumption. The contradictory opinions were given by the properties of oestrogen that soy had. This hormone is linked to the development and growth of breast cancer in postmenopausal women. Thus, some studies claimed that soy might affect the action of hormone therapies that are used in the treatment of breast cancer.
This new study claims the contrary. It found that isoflavones from soy foods are actually good for breast cancer patients. They are found to slow down the advance of an aggressive form of the disease, called hormone receptor-negative breast cancer.
The team of researchers, led by Dr. Fang Fang Zhang, looked at the link between a diet rich in isoflavones and death by any cause in 6000 women suffering from breast cancer. After nine years, those women who consumed high amounts of isoflavones had a risk lower by 21 percent of dying than those who consumed lower amounts or no amounts at all.
The decrease was strictly observed in women with the more aggressive form of the disease and in those who were not following treatments against oestrogens with tamoxifen, for example, which block the oestrogen effect.
Thus, Dr. Zhang declared that they did not meet a negative effect of soy on women who underwent hormone therapies. Also, soy had a protective effect in those women with hormone receptor-negative tumors.
Kathy Chapman, CEO of the committee on nutrition and physical activity at Cancer Council Australia, said that the confusion revolving around soy consumption and breast cancer patients should be cleared up, as she considered the study findings conclusive enough.
However, the officials are still reticent about soy supplements, so they advise women to be careful with these products. Soy is good in general for people to eat but breast cancer survivors should not try to take supplements for a bigger intake of substances found in soy.
Chapman advises cancer survivors in general to take care of themselves, follow healthy diets, and try to lead a lifestyle as healthy as possible.
