The Claim

A low-fat, plant-based diet combined with daily soybean consumption for 12 weeks results in significantly greater reductions in nighttime moderate-to-severe hot flashes than no dietary change in postmenopausal women.

Cause and effect

In plain English

Postmenopausal women who follow a low-fat, plant-based diet and eat soybeans daily for 12 weeks experience greater reductions in nighttime moderate-to-severe hot flashes than those who make no dietary changes.

See the scientific wording

The combination of a low-fat, plant-based diet and daily soybean consumption for 12 weeks leads to significantly greater reductions in nighttime moderate-to-severe hot flashes compared to no dietary change in postmenopausal women.

Why this might work

Eating soybeans every day gives the body a compound that gut bacteria turn into another compound that binds to a specific receptor in the brain's temperature control center. This binding tells the brain to stop triggering sudden blood vessel widening, which stops hot flashes from happening.

    Women who ate a plant-based diet with soybeans every day for 12 weeks saw their bad nighttime hot flashes drop by 84%, and more than half stopped having them altogether—while women who didn’t change their diet saw much smaller improvements.
