To identify commercial baby food varieties high in nitrate content using ion chromatography and compare the health risk associated with the consumption of high-nitrate water and high-nitrate commercial baby food.
Ion chromatographic determination of nitrate concentration in a variety of commercial baby foods.
University Hygienic Laboratory, University of Iowa College of Medicine, Iowa City.
Commercial baby foods with nitrate levels higher than 45 ppm include mixed vegetables, bananas, carrots, garden vegetables, spinach, green beans, and beets. The amount of nitrate in one 113-g (4 oz) jar of beets, for example, is equivalent to the amount of nitrate in nearly 5.5 L of water at 45 ppm nitrate.
A controlled clinical trial is needed to clarify how consuming high-nitrate foods correlates with methemoglobin levels in infants younger than 6 months.(Arch Pediatr Adolesc Med. 1994;148:490-494)
