A new study has found that a diet rich in vegetable proteins may prolong fertility as well as protect women from early menopause. Women who consumed about 6.5% of their daily calories as vegetables had 16% lower risk of early menopause compared to women whose intake was 4% of calories. The study published in the American Journal of Epidemiology examines the relationship between diet and risk of early menopause. Women have been entering this ongoing study since 1989 with nearly 116,000 participants aged 25 to 42. The study sheds light on how dieting contributes to fertility and early menopause.
