The Claim
Increases in the overall plant-based dietary index (PDI) and the unhealthful plant-based dietary index (uPDI) within a low-fat vegan diet intervention are independently associated with reductions in severe hot flashes, after adjustment for weight loss.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among people following a low-fat vegan diet, higher intake of plant-based foods—whether considered healthy or unhealthy—is linked to fewer severe hot flashes, independent of changes in body weight.
See the scientific wording
Within a low-fat vegan diet intervention, increases in the overall plant-based dietary index (PDI) and the unhealthful plant-based dietary index (uPDI) are independently associated with reductions in severe hot flashes, even after adjusting for weight loss, suggesting that the benefit may stem from replacing animal products with plant foods regardless of whether those plant foods are classified as 'healthy' or 'unhealthy'.
Eating more plant foods replaces animal products and lowers fat intake, which changes how the body processes estrogen. This leads to more estrogen being removed from the body through the gut, and plant compounds bind to brain receptors that control body temperature, making hot flashes less frequent and less severe.
What the research says
1 studyWomen who ate more plant foods—even sweets and potatoes—while on a vegan diet had far fewer hot flashes, even after losing weight. This suggests it’s not just about eating healthy plants, but just swapping meat and dairy for any plants that helps.
