the nutritional effects of whey protein concentrate: effect supplementation with concentrate on physiology female rats

In vitro analysis of whey protein concentrate (WPC), examining its chemical composition and its antioxidant and free-radical scavenging properties, has shown that: WPC is free from fat but rich in nitrogenous matter. Ultrafiltration has reduced the mineral content and concentrated the nitrogenous matter. Whey protein concentrate (WPC) possesses significant free radical-scavenging and antioxidant activity. Enriching the diet of rats with WPC leads to an increase in protein levels and antioxidant enzymes in red blood cells, as well as in the spleen and liver. The kidneys are the site of oxidative stress, characterised by an increase in renal TBARS levels following this supplementation, possibly due to the presence of a stress-inducing agent - whether endogenous or exogenous - which may have evaded the ultrafiltration process. This toxic agent with renal affinity (salt, acid) led to an increase in the level of lipoperoxidation, confirmed by a rise in renal TBARS levels and a reduction in the activity of the renal enzymatic antioxidant system.
