Nitrate is naturally found in various different vegetables, including root vegetables, collard greens, broccoli and cauliflower. The human body has the ability to convert nitrate into nitrite. Both of these compounds are considered as hazardous. Only legal limits of them are allowed in food and drinking water. These compounds have the ability to change normal hemoglobin (the chemical compound present in blood for transportation of oxygen) to met-hemoglobin. Normally, levels of met-hemoglobin are less than 2.5% of the body’s total hemoglobin. Excess of met-hemoglobin by nitrates from normal levels, reduces the ability of blood’s oxygen transportation to the blood cells. Reduction of oxygen from the blood cell can cause a bluish tint of the nose, lips and ears in minor cases (also named as blue-baby syndrome) in infants. While in some severe cases it can cause heart and respiratory problem, and even death. However, nitrates and nitrites can also react with other compounds either present in our body or in the food we are consuming to form substances that may cause cancer. These reactions are more probable to take place in the existence of protein. Meat is a ric h protein food. When nitrites in the presence of amino acids, are exposed to high temperature, they can form a compounds named nitrosamines. Scientists believe that these formations may be responsible for the relationship they have found between nitrates and nitrites and the diseases mentioned above. Exposure of nitrite or nitrate can also cause complications in pregnancy and health problems in infants. It nitrates/nitrites lose an oxygen atom it can turn into Nitric Oxide, an important signaling molecule. This molecule travels through the walls of artery and transmits signals to tiny muscle cells around
