It is known that nitrate and nitrite are closely related to cardiovascular diseases. Excessive consumption of ham, sausage and other processed meat products is easy to lead to cardiovascular diseases such as hypertension and arteriosclerosis. Consuming too much sodium nitrate in meat can also cause migraines.

Sodium nitrate has long been mined in Chile's Atacama Desert, a dry desert on earth. Atacama is also one of the areas rich in mineral resources. Although the negative health effects of sodium nitrate have attracted people's attention, it will make it very difficult to store and transport meat without it, because meat food is easy to corrupt.
