Most Women Unaware That Dietary Changes Can Reduce Hot Flashes

A recent poll reveals that most women are unaware that adopting a low-fat, plant-based diet including soy can significantly reduce hot flashes during menopause. Learn how dietary changes can improve menopausal symptoms and overall health.
As Menopause Awareness Month approaches in October, new research reveals that a significant number of women remain unaware of how diet can influence menopausal symptoms, particularly hot flashes. A recent poll conducted by the Physicians Committee for Responsible Medicine and Morning Consult found that only 43% of women recognize that modifying their diet could lessen the frequency and severity of hot flashes. This is notable considering existing studies that demonstrate a low-fat, plant-based diet—including foods rich in soy—can markedly decrease hot flashes and aid in weight management for menopausal women.
The poll, carried out from August 6 to 7, 2025, with 1,155 women participating, also uncovered misconceptions about soy consumption and ultra-processed plant foods. About 19% believed women should avoid soy during menopause, while 21% thought avoiding it was unnecessary. Furthermore, 11% thought ultra-processed plant foods such as plant-based meats might reduce hot flashes, whereas 22% believed they could exacerbate symptoms. Regarding weight, 13% thought such foods might promote weight loss, but 26% believed they could lead to weight gain.
Research led by Dr. Hana Kahleova and Dr. Neal Barnard highlights that a plant-based diet inclusive of soy can significantly reduce hot flashes, with some studies reporting an 88% decrease in moderate to severe episodes after 12 weeks. This diet not only alleviates symptoms but can also promote weight loss. In their trial, women who adhered to a low-fat, vegan diet with soy experienced fewer hot flashes and, on average, lost 8 pounds.
Despite these promising findings, awareness remains limited. Many women do not associate dietary habits with menopausal symptom management, and primary care settings often overlook this aspect. Experts urge clinicians to promote plant-based dietary interventions, emphasizing that even ultra-processed plant foods like soy milk and meat alternatives can contribute to symptom relief.
This gap in knowledge underscores the importance of continued education and awareness efforts, especially during Menopause Awareness Month. Incorporating a low-fat, plant-based diet may offer women a natural and effective way to manage hot flashes, control weight, and improve overall health during menopause.
