Special Vegan Diet Found To Decrease Hot Flashes by 95% – SciTechDaily

A new study shows that a low-fat vegan diet significantly reduces postmenopausal hot flashes by 95% and aids in weight loss. This diets impact on the gut microbiome, specifically the reduction of certain bacteria, is linked to the decrease in hot flashes, indicating a potential connection between diet, gut health, and menopausal symptoms. Further research is required to fully understand these findings.

A new study by the Physicians Committee for Responsible Medicine has revealed that a low-fat vegan diet that includes soy fosters changes in the gut microbiome that decrease postmenopausal vasomotor symptoms, or hot flashes, overall by 95%.

This diet not only completely eradicated severe hot flashes but also resulted in a 96% decrease in moderate-to-severe episodes. Furthermore, it effectively reduced both daytime and nighttime hot flashes by 96% and 94%, respectively. Additionally, participants following this diet experienced an average weight loss of 6.4 pounds.

Women who want to fight hot flashes should feed the bacteria in their gut a vegan diet rich in fruits, vegetables, grains, and beans, which also leads to weight loss and protects against heart disease and type 2 diabetes, says study co-author Hana Kahleova, MD, PhD, director of clinical research at the Physicians Committee for Responsible Medicine.

The new research is a secondary analysis of the WAVS trialthe Womens Study for the Alleviation of Vasomotor Symptomsthat the Physicians Committee previously published in the journalMenopause.

In the study, 84 postmenopausal women reporting two or more moderate-to-severe hot flashes daily were randomly assigned to either the intervention group that was asked to follow a low-fat vegan diet, including a half cup cooked soybeans a day, or to the control group that continued their usual diets for 12 weeks.

For the secondary analysis, stool samples from a subset of 11 participants were used to perform a gut microbiome analysis at baseline and after 12 weeks on a vegan diet. Changes in the amount of several families, genera, and species of bacteria were found.

The study is the first to find that reductions in the abundance of Porphyromonas and Prevotella corporis are associated with a reduction in severe day hot flashes. Prevotella corporis has also been found in the gut of people with rheumatoid arthritis and seems to have pro-inflammatory properties.

The decrease in the abundance of Clostridium asparagiforme was associated with a reduction in total severe and severe night hot flashes. Clostridium asparagiforme has also been found to produce trimethylamine-N-oxide, a compound associated with an increased risk of cardiovascular disease and type 2 diabetes. A decreased abundance of Clostridium asparagiforme may partially explain the beneficial effects of a plant-based diet on cardiovascular health and provide a possible link between hot flashes and incident cardiovascular disease.

Changes in the abundance of other bacteria looked at in the study may play a role in alleviating hot flashes by stabilizing estrogen levels, reducing inflammation, and increasing satiety, among other benefits.

The authors say that larger randomized clinical trials are needed to further investigate these findings.
