Zinc: Dietary Sources and Bioavailability
11-409 12015 Zinc, as a cofactor for numerous enzymes in the body, plays an important role in growth and development, wound healing, taste acuity and appetite, immune function, and gene expression (1-4). Although zinc is needed in only small amounts by the human body, some people are vulnerable to mild to moderate zinc deficiency (1). Zinc deficiency results not only from a diet low in zinc-ric...
متن کاملOral iron and the bioavailability of zinc.
The oral bioavailability of zinc was studied in nonpregnant adults before and 24 hours after two weeks of oral supplementation with iron and folic acid. Bioavailability was greatly reduced, and the shape of the plasma curves suggested that this was due to impairment of the intestinal absorption of zinc. The findings suggest that the reduced bioavailability of zinc occurs because of interelement...
متن کاملZinc homeostasis and neurodegenerative disorders
Zinc is an essential trace element, whose importance to the function of the central nervous system (CNS) is increasingly being appreciated. Alterations in zinc dyshomeostasis has been suggested as a key factor in the development of several neuropsychiatric disorders. In the CNS, zinc occurs in two forms: the first being tightly bound to proteins and, secondly, the free, cytoplasmic, or extracel...
متن کاملBioavailability of zinc in ground beef.
Based on zinc uptake in chick tibia, Zn bioavailability in cooked ground beef was equal to that of Zn in an inorganic standard (ZnSO4), whether Zn supplements were added to a soy-concentrate diet containing phytate or to a phytate-free egg-white diet. With both diet types, total tibia Zn was a linear (P < .01) function of supplemental Zn intake from ZnSO4, but the slope of the linear regression...
متن کاملRelative Bioavailability of Different Zinc Sources Based on Tissue Zinc Concentration in Broiler Chickens
This research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. For that, 312 day-old male Ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. Chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. Diets include...
