In vitro absorption of nutrients from small intestine of rats fed peroxidized oil.

Feeding of diet containing peroxidized oil (peroxide value approximately 90 mEq/kg) at 10% level for 4 weeks altered the absorptive function of intestine. Rate of in vitro absorption of nutrients especially sucrose and protein hydrolysate (amino acids) was considerably reduced. Absorption of glucose, fructose and Ca2+ was only marginally affected.
