Causes of iron and zinc deficiencies and their effects on brain

J Nutr. 2000 Feb;130(2S Suppl):347S-349S. doi: 10.1093/jn/130.2.347S.


Low consumption of foods rich in bioavailable iron (Fe) and zinc (Zn) such as meat, particularly red meat, and high consumption of foods rich in inhibitors of Fe and Zn absorption, such as phytate, certain dietary fibers and calcium, cause Fe and Zn deficiencies. Neuropsychologic impairment is one of several potential outcomes of these deficiencies.
