Nitrate is a stable compound that is not easily converted into other forms of nitrogen. It is found naturally in soil and water, and it can also be added to food as a preservative. Nitrate itself is not harmful to the body, but it can be converted into nitrite by bacteria in the mouth or stomach.
Nitrite is a more reactive compound that can be harmful to the body in high doses. It can cause a condition called methemoglobinemia, which is a rare but serious blood disorder that can lead to death if not treated promptly. Nitrite can also react with other compounds in the body to form carcinogenic nitrosamines.
The main sources of nitrate and nitrite in the diet are:
* Processed meats, such as bacon, sausage, and hot dogs
* Fermented foods, such as sauerkraut and kimchi
* Well water
* Leafy green vegetables
The amount of nitrate and nitrite in food and water varies depending on a number of factors, including the type of food, the amount of processing, and the storage conditions.
The Food and Drug Administration (FDA) has set limits on the amount of nitrate and nitrite that can be added to food. The FDA also recommends that people avoid drinking water that contains high levels of nitrate.
If you are concerned about your intake of nitrate and nitrite, you can talk to your doctor or a registered dietitian.
