A diet substituting animal products with plant-based foods — whether unprocessed or ultra-processed — and including soybeans can lead to significant weight loss and a reduction in severe hot flashes in postmenopausal women, according to new research published in the journal Menopause. “Avoiding animal products and instead eating vegan foods, including veggie burgers, breads and cereals, and fruits and vegetables, is a prescription for fighting hot flashes,” says Hana Kahleova, MD, PhD, director of clinical research for the Physicians Committee for Responsible Medicine.
