Exploring the sources and risks of nitrates and nitrites : are we putting our health at risk?

Abstract

Nitrates and nitrites are commonly found in food and water sources and are used as preservatives in various processed foods. While they can provide many benefits such as preventing spoilage and bacterial growth, studies have shown that excessive consumption of nitrates and nitrites can lead to several health risks. The main sources of nitrates and nitrites include fertilizers, manure, and sewage. which can contaminate the soil and water. In addition, they are present in high levels in cured meats such as bacon, ham and hot dogs. These foods have been linked to an increased risk of cancer, particularly colorectal cancer, as well as other health issues such as heart disease, diabetes and birth defects.
