Eating more nitrites, even just a tiny bit extra each day, might raise your chance of getting stomach cancer, according to research that looked at several studies.

Eating a lot of foods with nitrites might raise your chances of getting stomach cancer by about one-third, according to a big review of many studies.

Researchers followed nearly 10,000 Finnish adults for 24 years and found that eating foods with nitrates or nitrites didn't increase their chances of getting stomach or intestinal cancers.

Eating more nitrate-rich foods might lower your chances of getting stomach cancer by about 20%, based on a big review of many studies, especially in European countries.

Eating more foods with certain chemicals called nitrites and nitrates might slightly raise your chance of getting cancer later in life, according to a big study that followed people for 12 years.

People who have more nitrate and nitrite in their saliva seem to be less likely to get stomach cancer.
