The Claim
A 12-week low-fat vegan diet supplemented with soybeans reduces the frequency of severe hot flashes by 92% in postmenopausal women, from an average of 1.3 per day to 0.1 per day, compared to no change in a control group.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Postmenopausal women who followed a low-fat vegan diet with soybeans for 12 weeks experienced a 92% reduction in severe hot flashes, going from 1.3 per day to 0.1 per day, while women in a control group showed no change.

Soy compounds enter the bloodstream and bind to specific receptors in the brain's temperature control center. This binding reduces nerve signals that cause blood vessels in the skin to suddenly widen, which stops the sudden feeling of intense heat.
What the research says
1 studyWomen who ate a low-fat vegan diet with soybeans every day for 12 weeks had far fewer intense hot flashes—down from about once a day to less than once every 10 days—while women who didn’t change their diet saw no difference. The soy in their diet was likely the reason.
