A new study published by the North American Menopause Society in the journal menopauseThe diet intervention was found to be as effective (88%) as hormone replacement therapy (70%-90%) for reducing menopausal hot flashes, without the associated health risks.

The WAVS trial – the Women’s Vasomotor Symptom Relief Study – found that a plant-based diet rich in soy reduced moderate to severe hot flashes by 88% and helped women lose an average of eight pounds in 12 weeks.

“We don’t fully understand why this combination works, but these three seem to be key — avoid animal products, reduce fat, and add a serving of soy,” explains lead researcher Neil Barnard, MD, chair of the Physicians’ Committee. Assistant Professor at The George Washington University School of Medicine.

“Our results mirror diets in places in the world, such as westernized Japan and the modern Yucatan Peninsula, where a low-fat, plant-based diet including soybeans is prevalent and where postmenopausal women experience fewer symptoms.”

The study published today is the second phase of a two-part trial, the first of which was also published in menopause in 2021. The fall timing of the first trial raised the question of whether this improvement in symptoms might be attributable to cooler temperatures. But women who started the study as the weather warmed in spring had the same benefit, ruling out the effect of outside temperature.

“These new findings suggest that changing the diet should be considered as a first-line treatment for bothersome vasomotor symptoms, including night sweats and hot flashes,” Dr. Barnard explains.

The study included 84 postmenopausal women who reported two or more hot flashes per day. They were randomly assigned to either an intervention group—consisting of a low-fat plant-based diet, including half a cup of cooked soy per day—or a control group that made no changes in diet for 12 weeks.

“This study demonstrates the effectiveness of dietary intervention in treating menopausal symptoms,” Dr. Barnard explains. “In addition, it is diet specifically that is expected to reduce the health concerns of many women who reach menopause: increased risk of heart disease, breast cancer, and memory problems.”

Summary

Nutritional intervention for vasomotor symptoms of menopause: a randomized controlled trial

Goal

Postmenopausal vasomotor symptoms disrupt quality of life. This study examined the effects of a dietary intervention on vasomotor symptoms and quality of life associated with menopause.

Methods

Postmenopausal women (n = 84) reporting at least two moderate to severe hot flashes per day were randomly assigned, in two consecutive groups, to an intervention that included a low-fat vegetarian diet and cooked soy (cup) [86 g] daily) or for a control group who did not make any dietary changes. During the 12-week period, a mobile application was used to score hot flashes (frequency and severity), and motor, psychosomatic, somatic and sexual symptoms were assessed using the Menopause Quality of Life Questionnaire. The differences between the group were evaluated for persistence (R Tests (and binary)χ2/ McNemar tests) results. In a study subsample, urinary equilibrium was measured after consuming 1 cup (86 g) of cooked whole soybeans twice daily for 3 days.

consequences

In the intervention group, moderate to severe hot flashes decreased by 88% (s <0.001) compared to 34% for the control group (s <0.001; between the group s <0.001). At 12 weeks, 50% of those completing treatment in the intervention group reported no moderate to severe hot flashes at all. Among the controls, there was no change in this variable from baseline (χ2 a test, s <0.001). The seasonal production situation was not associated with the degree of improvement. The intervention group reported greater reductions in the menopause-specific quality of life questionnaire (s = 0.004), physical (s = 0.01), and Nationality (s = 0.03) domains.

Conclusions

A nutritional intervention consisting of a plant-based diet, reduced oils, and daily soybeans reduced the frequency and severity of menopausal hot flashes and their associated symptoms.
