Association between dietary nitrate and nitrite intake and site specific cancer risk: evidence from observational studies

When added to processed foods in this way, both nitrates and nitrites can form nitrosamines in the body, which can increase your risk of developing cancer.

The present meta-analysis provided modest evidence that positive associations of dietary nitrate and negative associations of dietary nitrite with certain cancers.
