Supplementing breakfast with a medical nutritional drink enriched with vitamin D and leucine-enriched whey protein improves postprandial muscle protein synthesis and muscle mass in healthy older men. Diets containing whey protein or soy protein isolate protect against 7,12-dimethylbenzene (a), anthracene-induced mammary tumors in female rats. The increases in muscle strength induced by resistance training in trained men are maintained after 2 weeks of detraining and are not differentially affected by supplementation with whey protein.
