Diets high in allium vegetables, such as onions and garlic, are associated with low endometrial cancer risk.

This study examined the correlation between the consumption of allium vegetables, such as onions and garlic, and the incidence of endometrial cancer. Using validated and reproducible food frequency questionnaires, researchers collated and assessed the diets of 1362 subjects recruited from an Italian case control study. The endometrial cancer odds ratio of each participant in this study was also evaluated.

Researchers observed that consistent consumption of more than 2 portions (160g) of onions and large amounts of garlic per day significantly decreased the risk of developing endometrial cancer. The results of this study provide further evidence that strengthens the hypothesis that allium vegetables, particularly onions and garlic, may have a substantial protective effect against the development of endometrial cancer in women.
