A randomized controlled trial of postmenopausal women published in 2023 found that switching to a healthy plant-based diet, including half a cup of daily soybeans, cut their number of hot flashes by 30% and their number of moderate-to-severe hot flashes by 42%, compared to people who continued with their usual diet.
After three months of eating this way, the majority of women even reported becoming free from moderate-to-severe hot flashes, while none of the women eating their regular diet experienced this tremendous benefit. As a bonus, women who ate a plant-based diet with daily soybeans also improved their quality of life in the psychosocial, physical, and sexual domains, a true testament to the power of soy and other plant foods.
