Effect of dietary CLA isomers on selenium, zinc, copper, chromium, magnesium and calcium levels in rat liver

Abstract

The effects of diets enriched with 1-2% conjugated linoleic acid isomers (CLA) and/or 2 ppm selenium (as Na2SeO4) on the level of Se, Zn, Cu, Cr, Mg and Ca in the rat liver were studied. Feeding selenium (Se) and/or CLA isomers resulted in significant changes or trends changing the level of Zn, Cu, Cr, Mg and Ca in the liver. The dosage of Se, regardless of the presence of CLA isomers, significantly increased the Se level in the liver. Trans10cis12CLA in the diet most efficiently elevated Zn, Cu, Mg and Ca levels, and, numerically, the Cr content in the liver.
