The effects of dietary chromium supplementation along with discontinuing a high-fat diet on the microbial enzymatic activity and the production of SCFAs in the faeces of rats

The extracellular, intracellular, total activity and release rate of faecal bacterial α –glucosidase, β –glucosidase, β-glucuronidase, β-xylosidase during the experimental feeding period in rats. Faecal short-chain fatty acids, faecal pH during the experimental feeding period in rats. Data were obtained during an in vivo experiment on rats. The 18-week study was divided into two phases: a 9-week introductory and a 9-week experimental period. Rats were given two different diets: a low-fat (C diet) and a high-fat (F diet) diet. Furthermore, two types of supplemental dietary chromium were used: conventional Cr-picolinate and novel Cr nanoparticles (Cr-Pic and Cr-NPs, respectively), both at the pharmacologically appropriate Cr dose of 0.3 mg/kg body weight.
