Jan 10,  · Data on occurrence of nitrate, nitrite and N‐nitrosocompounds in food and drinking water, and on total dietary intakes are reviewed. Metabolic, toxicological and epidemiological studies are surveyed and the implications with respect to safety evaluation are addressed. It is concluded that, on the basis of recent long‐term animal studies and of clinical experience in man, the current Cited by: The nitrite from these and other sources, including that purposely added to food, presents a toxic hazard both because of the direct toxicity of nitrite, and by the formation of carcinogenic N‐nitroso compound by reaction with amino compounds. Administration of toxic amounts of nitrite induces hisn-alarum.com by: Nitrite and N-nitroso compounds present in the diet contribute relatively small amounts to the body burden and the major source of these biologically reactive compounds is derived from the bacterial and mammalian metabolism of ingested nitrate. Additionally, endogenous synthesis provides an important source contributing to the body burden of nitrate.

So there is nothing intrinsically wrong with nitrates or nitrites that are ingested via food. Ah, but here’s the problem: When heated, nitrites react with the NH3 (amine) group on proteins and yield nitrosamines and other N-nitroso compounds such as N-nitrosodimethylamine, NDMA. We have plenty of experimental evidence that the 20+ known. Much of the confusion stems from the fact that nitrates and nitrites occur in many foods, including vegetables and fruit. Upon ingestion, nitrates and nitrites are converted to nitric oxide, the master vasodilator (artery relaxing agent) that thereby contributes to healthy arteries and blood pressure. N-nitroso compounds (NOCs) are found in processed meat and are formed endogenously from intake of nitrite and nitrate. Endogenous NOC formation is antagonized by nitrosation inhibitors in fruit and vegetables (e.g., vitamin C) and promoted by heme in red hisn-alarum.com by: The Health Effects Of Nitrate, Nitrite, And N- Nitroso Compounds: Part 1 Of A 2-part Study, Volume 1 [Assembly of Life Sciences (U.S.).

Jan 14,  · In the modern diet, nitrates can be found both in nitrate-rich plant foods and in processed meats. However, while nitrates from plant foods promote nitric oxide production, processed meats trigger conversion of nitrates into carcinogenic N-nitroso compounds.

Part 1 of The Health Effects of Nitrate, Nitrite, and N-nitroso Compounds: Study by the Committee on Nitrite and Alternative Curing Agents in Food, Assembly of Life Sciences. Even though vegetables also contain nitrates/nitrites, they are rarely exposed to such high heat. Nitrosamines can also form during the acidic conditions in the stomach. Bottom Line: When nitrites and amino acids are present, carcinogenic compounds called nitrosamines can form during high heat cooking.
