Study shows diet causes 84% drop in troublesome menopausal symptoms–without drugs

A new study, published by the North American Menopause Society in the journal Menopause, found a plant-based diet rich in soy reduces moderate-to-severe hot flashes by 84%, from nearly five per day to fewer than one per day. During the 12-week study, nearly 60% of women became totally free of moderate-to-severe hot flashes. Overall hot flashes (including mild ones) decreased by 79%.

The study, called the WAVS trial–the Women’s Study for the Alleviation of Vasomotor Symptoms-shows that diet changes can be much more powerful for treating hot flashes than scientists had thought. Vasomotor symptoms refer to night sweats, hot flashes, and flushes.

The study used no hormone medications or extracts. Instead, the research team tested a combination of a low-fat plant-based diet plus 1/2 cup of ordinary soybeans added to a salad or soup each day.

“This is a game changer for women aged 45 and over, most of whom we now know can get prompt relief from the most severe and troubling menopause symptoms without drugs,” says lead researcher Neal Barnard, MD, president of the Physicians Committee and adjunct professor at the George Washington University School of Medicine.
