The present inventors discovered that the onset of galactosamine hepatopathy is suppressed by nutritional compositions comprising as essential ingredients: whey protein hydrolysates； lecithin and oils and fats high in oleic acid, which are able to improve the lipid metabolism； and palatinose having an insulin-sparing effect. Furthermore, the whey protein hydrolysate included in the nutritional compositions was found to suppress endotoxin-induced TNF-a and interleukin 6 (IL-6) production in macrophages.
