Baby Food Jars as a Dietary Source of Essential (K, Na, Ca, Mg, Fe, Zn, Cu, Co, Mo, Mn) and Toxic Elements (Al, Cd, Pb, B, Ba, V, Sr, Li, Ni)

Abstract

Baby food from jars is made of meat, vegetables or fruits, and might be a valuable source of essential elements such as Na or K. However, these infant products could also be a source of toxic elements such as Al or Cd, which are dangerous to infants. In total, 45 samples of various kinds of baby food in jars (meat, vegetables, fruit and mixed) were analyzed using inductively coupled plasma spectrometry (ICP OES) with the aim of evaluating the daily intake of essential elements (K, Na, Ca, Mg, Fe, Zn, Cu, Co, Mo, Mn) and dietary exposure to toxic elements (Al, Cd, Pb, B, Ba, V, Sr, Li, Ni). Mixed jars registered the highest concentrations of Na, Ca, Zn, Fe. Al (8.22 ± 8.97 mg/kg wet weight) stands out in vegetable jars. In total, 130 g/day of mixed jars fulfills daily Zn and Ca requirements. These consumption scenarios (130 g/day, 250 g/day) supposed high Mn intakes (40 times higher than the recommended value), which could pose a risk to infants’ health. Pb, Ni, Cd and Al intakes exceed the maximum values. It is recommended to avoid the daily consumption of these products since it can pose a risk to the health of infants. Chemical compounds studied in this article: Nitric acid (PubChem: CID 944).
