Are there specific diets that are better for menstrual cycle health?

Specific diets, such as the Mediterranean diet,^[1] low-carbohydrate diet,^[2] DASH diet,^[3] low-fat vegetarian diet,PMID10674588 low glycemic index diet,^[4] and ketogenic diet,^[5] may support menstrual cycle health in people with certain conditions, but there is no evidence to support a single “best” diet for all menstruating people. In fact, some studies find that the Mediterranean diet, low carbohydrate diets, and diets with too much fiber are associated with irregular menstrual cycles.^[6][7] Still other studies report that in people with overweight and obesity, weight loss improves menstrual regularity more than a specific dietary composition.^[8] This variety of findings highlights the importance of an individualized approach to diet. However, it is very clear that overly restrictive diets and eating disorders negatively affect reproductive health.^[9]
