SALAS-GONZALEZ, María Dolores et al. Zinc and its relation to insulin resistance in children. Nutr. Hosp. [online]. 2021, vol.38, n.spe2, pp.68-70.  Epub 01-Nov-2021. ISSN 1699-5198.  https://dx.doi.org/10.20960/nh.3802.

Zinc is an essential trace element involved in catalytic, structural, and regulatory functions, participating also in the metabolism of nutrients. Its role in insulin resistance appears to be of great importance, as it is involved in oxidative stress, the endocrine regulation of insulin, and the regulation of glucose uptake. For this reason, both intake and serum levels of zinc are inversely related to insulin resistance.

Currently, zinc intake in children is low, and zinc deficiency exists in a significant proportion. Zinc can be found in meat, fish, eggs, and dairy products. Although it certainly is present in foods of plant origin, their high phytate contents generally reduce its bioavailability. For this reason, it is important to monitor intake throughout childhood, and to consider supplementation in children with insulin resistance or obesity.
