What are nitrates nitrites and nitrosamines?
What are nitrates nitrites and nitrosamines?

When the nitrites manufactured in our mouth are swallowed, one of the things that can happen is that they react in the strongly acidic environment of the stomach to form nitrosamines – some of which are carcinogenic and have been linked with bowel cancer.
Are nitrates and nitrosamines the same?
A high consumption of processed meats is linked to an increased gastric cancer risk, and many people consider nitrates/nitrites as the main reason for that [6]. Nitrosamines are produced by chemical reactions of nitrates, nitrites and other proteins.

What foods are high in nitrosamines?
Which foods contain nitrosamines?
How do nitrites turn into nitrosamines?
Nitrate is reduced to nitrite by the enzyme nitrate reductase, which occurs in a number of bacteria. As discussed earlier, nitrite is converted to nitrosating agents which subsequently react with amines in the meat during processing, storage, and cooking to form nitrosamines.
