Colorectal cancer and adenomatous polyps in relation to allium vegetables intake: a meta-analysis of observational studies.

Consistent consumption of diets high in allium vegetables, such as onions and garlic, may help inhibit the development and proliferation of cancerous cells and adenomatous polyps in the colon and rectum.

The objective of this study was to examine the correlation between allium vegetable intake and the odds of developing colorectal cancer and adenomatous polyps. Researchers conducted a meticulous meta-analysis on data obtained from 16 studies. They observed that high consumers of allium vegetables, such as garlic and onions, had low risk of developing adenomatous polyps and cancerous cells in the colon and rectum. The results of this study support the hypothesis that regular consumption of diets rich in allium vegetables, such as garlic and onions, may confer significant protection against the development of colorectal cancer.
