The Claim
In postmenopausal women, increased dietary intake of daidzein is independently associated with a 92% reduction in the frequency of severe hot flashes after controlling for energy intake and changes in body mass index.
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 consume more daidzein in their diet experience 92% fewer severe hot flashes than those who consume less, after accounting for total calorie intake and body weight changes.
See the scientific wording
In postmenopausal women, increased dietary intake of daidzein (an isoflavone) is independently associated with a 92% reduction in the frequency of severe hot flashes, after controlling for energy intake and changes in body mass index, suggesting daidzein may play a specific role in mitigating this symptom.
Daidzein enters the bloodstream and binds to a specific receptor in the brain's temperature control center. This binding calms overactive nerve signals that cause sudden blood vessel widening, preventing the intense heat surges known as hot flashes.
What the research says
1 studyIn a study with postmenopausal women, those who ate more soy (which has daidzein) had far fewer severe hot flashes—even when researchers accounted for weight loss and calorie intake. This suggests daidzein itself may be what’s helping reduce hot flashes.
