WASHINGTON, Dec. 30 /PRNewswire/ -- Soy protein continues to be recommended as a remedy for menopausal problems such as hot flashes, according to Cornell University's Weill Medical College, while a new report has found that post-menopausal hormone therapy can cause an aggressive form of breast cancer.
The medical college's Center for Women's Healthcare, in its publication the Food & Fitness Advisor, reported on findings by a University of New Mexico scientist who says clinical trials have indicated soy protein can help relieve adverse menopausal symptoms.
Soy contains isoflavones, the most potent of which are genistein and dadzein. Soy products have been recommended to relieve menopausal conditions following findings in 2002 that post-menopausal hormone therapy can increase the risk of breast cancer, heart attacks, stroke and dementia.
Reporting on findings for soy and herbal supplements, Dr. Tieraona Low Dog of the University of New Mexico told a recent meeting of the North American Menopause Society that five of 14 trials of soy or soy isoflavones found a positive effect for soy as a remedy for hot flashes. Other trials showed mixed or no positive results.
"The recommended amount is 20 to 50 grams of soy protein a day from soy milk, protein bars, powder drinks, soy beans, meat substitutes or tofu," the Food & Fitness Advisor said.
Earlier, the Cornell health publication reported on a new and more detailed analysis of results from the landmark Women's Health Initiative study, which was abandoned in 2002 because of concerns that post-menopausal hormone therapy combining estrogen and progestin can cause breast cancer.
The latest report, from researchers at Wayne State University in Detroit, Mich., examined data from the Women's Health Initiative and found that short- term use of one hormone therapy drug can cause an aggressive form of breast cancer and also make it more difficult to find tumors on mammograms until they have progressed to a more advanced stage.
