Postmenopausal Vasomotor Symptoms Significantly Improve With Dietary Intervention
The occurrence of postmenopausal vasomotor symptoms—also known as “hot flashes”—and other symptoms were reduced after the introduction of a plant-based diet, proving to be more effective and presenting fewer risks than hormone replacement therapy, according to a recent study.
“Postmenopausal vasomotor symptoms cause recurrent discomfort, disrupt sleep, and reduce quality of life,” the researchers wrote.
Participants in the study were split into 2 successive cohorts where they either participated in a low-fat, vegan diet, or a control group with no dietary changes. A total of 84 postmenopausal women who reported at least 2 moderate-to-severe vasomotor symptoms daily participated in the study in which they recorded their frequency and severity of hot flashes using a mobile application for 12 weeks.
The cohort of women who changed their diet reported a decrease in vasomotor by 88% (P < 0.001) compared with 34% of women in the control group (P < 0.001). Further, at the final week, 50% of women reported no vasomotor symptoms at all with the change in diet.
“This study has several strengths,” the researchers wrote. “Because participants were not confined to a metabolic ward and used widely available foods, rather than commercial products, the findings readily translate to nonresearch settings.”
