Short-term: Excessive levels of nitrate in drinking water have caused serious illness and sometimes death. The serious illness in infants (aka Blue Baby Syndrome) is due to the conversion of nitrate to nitrite by the body, which can interfere with the oxygen-carrying capacity of the childs blood.
Hereâs how to keep added nitrates and nitrites out of your body: 1  Minimize your consumption of processed foods and cured meat products such as hot dogs, sausage and cold cuts. 2  Check labels carefully and avoid products that list sodium or potassium nitrates and nitrites. 3  Eat organic food.  Find out if your water is tainted with nitrates or nitrites. Public drinking water utilities test for these compounds and must disclose their results. If you drink well water, your local health department can help you find out if this is a problem in your area. You can also have your water tested by a laboratory.
