Menopausal women with gut-friendly diets report 30% fewer sleep disturbances and hot flushes
Spector: ZOE research found that menopausal women eating gut-friendly diets (30+ plants, fermented foods) reported 30% fewer hot flushes and sleep disturbances. The microbiome may modulate hormonal symptoms through phytoestrogen metabolism.
