Can nitrates increase risk of cancer?

High nitrate intake may be associated with a decreased risk of gastric cancer, whereas nitrite intake may increase the risk of glioma and thyroid and gastric cancers. At this time, no studies have shown a consistent association between high intakes of nitrate or nitrite and other types of cancers.

Are nitrites carcinogenic?

Meat processing such as curing (e.g. by adding nitrates or nitrites) or smoking can lead to the formation of potentially cancer-causing (carcinogenic) chemicals such as N-nitroso-compounds (NOC) and polycyclic aromatic hydrocarbons (PAH).

Is high nitrates in water bad?

Sodium nitrate, a preservative that’s used in some processed meats, such as bacon, jerky and luncheon meats, could increase your heart disease risk. It’s thought that sodium nitrate may damage your blood vessels, making your arteries more likely to harden and narrow, leading to heart disease.

What is bad about nitrates in food?

Manufacturers add nitrates and nitrites to foods such as cured sandwich meats, bacon, salami or sausages to give them color and to prolong their shelf life. 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.
