The Claim

Daily consumption of 86 grams of whole soybeans as part of a low-fat, plant-based diet is associated with an increased proportion of postmenopausal women who produce equol, a metabolite linked to reduced hot flash severity, although equol levels were not directly measured in the study.

In plain English

Postmenopausal women who eat 86 grams of whole soybeans daily as part of a low-fat, plant-based diet are more likely to produce equol, a compound associated with less severe hot flashes.

See the scientific wording

Daily consumption of 86 grams of whole soybeans as part of a low-fat, plant-based diet may increase the proportion of postmenopausal women who produce equol, a metabolite linked to reduced hot flash severity, though this study did not directly measure equol levels.

Why this might work

Eating soybeans gives the body a compound called daidzein, which gut bacteria turn into equol. Equol attaches to a specific receptor in the brain that controls body temperature, making it less likely for blood vessels to suddenly widen and cause hot flashes.

    Women who ate half a cup of soybeans every day with a plant-based diet had way fewer and less severe hot flashes. Even though the study didn’t check for equol directly, fewer hot flashes is what equol is supposed to help with — so this suggests soy might be helping their gut make equol.
