Data of analysis of the combined effect of diversified Zn(II) content in the diet and Cr(III) supplementation on the body composition in Wistar rats

The data concern the combined effect of diversified Zn(II) content in the diet and Cr(III) supplementation on the body composition (body weight, adipose tissue content, muscle tissue content, fluid content). The in vivo experiment was conducted on Wistar rats randomly assigned to 6 experimental groups with different dietary Zn levels (deficient D, recommended K, excess N) and at the same time supplemented with Cr(III) at doses of 1 and 50 mg/kg for 6 weeks (5-6 males and 6 females). The study adhered to strict ethical standards for animal research and was approved by the Local Ethical Committee in Poznań, Poland (No. 48/2018). Measurements were made using a MiniSpec IF90II laboratory animal body composition analyzer (Bruker LF, Germany).
