High-carb Diets Linked to Early Menopause

A University of Leeds study has linked high-carb diets with early-onset menopause – although some experts argue the results are inconclusive.

The study, published in the Journal of Epidemiology & Community Health, tracked the typical dietary intake of 14,172 women, 914 of whom went through a natural menopause during the study period.

A diet high in refined carbohydrates such as rice and pasta was associated with menopause coming one and a half years earlier than the average age of 51. The authors speculate that these foods may increase the risk of insulin resistance, which in turn can raise oestrogen levels. This may contribute to an earlier age at menopause, the authors say. On the other hand, women who followed a diet high in legumes such as peas, beans and lentils, went through menopause a year and a half later than average.

However, some experts have said the study fails to draw a direct link between diet and age at onset of menopause.

Dr Channa Jayasena, clinical senior lecturer and consultant in reproductive endocrinology and andrology at Imperial College, said: “The body’s metabolism plays an important role in regulating ovulation and having periods. It is tempting to speculate that this provides a recipe for delaying menopause. Unfortunately, a big limitation of these observational studies is their inability to prove that dietary behaviour actually causes early menopause. Until we have that type of proof, I see no reason for people to change their diet.”
