The copper and zinc contents of 25 rations for adult horses were evaluated. The total amount of copper and zinc daily ingested was obtained by adding the amount of each element contained and added of the commercial feed to the amount contained in ingested ...
Ever since oxidation has been known to be involved in atherogenesis, antioxidants have received considerable attention as potential antiatherogenic agents. The lipid-soluble vitamin E is the main antioxidant carried by lipoproteins. Zinc is a water-...
Despite trace elements and vitamins are major public health problems in some African countries, there are few studies reporting micronutrient status in North Africa. Therefore, it could be interesting to evaluate plasma concentrations of vitamin A, E and ...
The aim of the present study was to investigate the time-course of changes in hepatic lipid peroxidation, cytochrome P450 and metallothionein concentrations, and superoxide dismutase and catalase activities in relation to the onset and development of ...
A combination of dietary and host-related factors determines iron and zinc absorption, and several in vitro methods have been developed as preliminary screening tools for assessing bioavailability. An expert committee has reviewed evidence for their ...
The focus of this paper is on the application of measurements of zinc absorption in human research, especially studies designed to assess the efficacy of intervention strategies to prevent and manage zinc deficiency in populations. Emphasis is given to ...
Micronutrient deficiencies are prevalent worldwide and have detrimental effects on human health. Complex interactions between micronutrients and other dietary components largely determine micronutrient bioavailability, and understanding these interactions ...
Low bioavailability of zinc in certain diet types may contribute to zinc deficiency and its consequences in populations. As a result, several experimental models including animal models, in vitro dialyzability models, and Caco-2 cells, have been used to ...
Background: Extrinsic labeling techniques are typically used to measure fractional absorption of zinc (FAZextrinsic) but none have been adequately evaluated. Objective: To compare determination of the quantity of zinc absorbed (TAZextrinisic) using ...
Objective: This study was conducted to test the efficacy of a multiple micronutrient-fortified cooking salt. Methods: A randomized controlled trial with a pre- and post-test design was used to study children 5 to 18 years of age, with an experimental (n=...
Estimated average requirements for micronutrients are central to deriving Dietary Reference Values. These are used for nutrition policies and programs, and also for regulatory and labeling purposes, and are traditionally devised to cover the needs of ...
Several bioavailability algorithms have been proposed for iron and zinc, confirming the need for these tools while emphasizing the challenge of deriving algorithms with accepted accuracy. This manuscript briefly reviews current evidence on the accuracy of ...
Individuals at highest risk of zinc deficiency (children, elderly, pregnant and lactating women, morbidly ill, alcoholics) have a higher risk of infection. Whereas the essential role of zinc in maintaining adaptive immunity is well recognized, much less ...
