The Claim

A low-fat, plant-based diet with daily soybean consumption for 12 weeks significantly improves quality of life in postmenopausal women by reducing vasomotor, psychosocial, physical, and sexual symptom burden compared to no dietary change.

Cause and effect

In plain English

Postmenopausal women who follow a low-fat, plant-based diet with daily soybeans for 12 weeks experience lower symptom burden in vasomotor, psychosocial, physical, and sexual domains compared to those who make no dietary changes.

See the scientific wording

A low-fat, plant-based diet with daily soybean consumption for 12 weeks significantly improves quality of life in postmenopausal women, with greater reductions in vasomotor, psychosocial, physical, and sexual symptom burden compared to no dietary change.

Why this might work

Eating soybeans daily allows gut bacteria to convert a compound in soy into equol, which activates a specific receptor in the brain that controls body temperature. This stops the brain from triggering sudden heat responses, reducing hot flashes. At the same time, the plant-based diet improves how the body handles sugar, which further calms down abnormal blood vessel reactions and lowers stress, physical discomfort, and sexual symptoms.

    Women who ate a plant-based diet with soybeans every day for 12 weeks felt better in every way—fewer hot flashes, less stress, more physical comfort, and improved sexual well-being—compared to women who didn’t change their diet.
