People are often concerned when they hear about nitrates and nitrites because it is widely known that these compounds can form carcinogenic nitrosamines. However, scientists have pointed out that this perception may be biased. In reality, nitrates and nitrites are essential for the human body. The potential risk these substances present to human health is influenced by the specific types of food from which they are derived.
What Are Nitrates and Nitrites, and Where Are They Found?
A common misconception is that nitrates are exclusively found in processed meats. As food additives, nitrates are primarily used in processed meats and specific types of cheese to inhibit the growth of Clostridium botulinum (which can produce a neurotoxin), improve microbiological safety, and extend shelf life.The truth is that nitrates and nitrites are naturally present in various foods and play a role in the nitrogen cycle between the air, soil, and water environments.
