A nutritional or pharmaceutical composition containing a fat component, a protein component and a carbohydrate component and comprising whey and casein. The composition has a weight ratio of casein to whey is 1:1 to 1:2.4 and that the composition contains: a) at least 3 grams arginine per 100 grams protein； b) at least 10 wt. % linoleic acid based on total fatty acids； c) at least 1 wt. % alpha linolenic acid based on total fatty acids； d) at least one long chain-polyunsaturated fatty acid in an amount exceeding 0.1 wt. % based on total fatty acids. The long chain polyunsaturated fatty acid being docosahexaenoic acid, arachidonic acid and eicosapentaenoic acid； e) 5 to 25 wt. % of at least one polyunsaturated fatty acid based on total fatty acids； and f) 2 to 12 grams indigestible oligosaccharides having a degree of polymerization of 2 to 100 per 100 gram dry weight of the composition. The composition reduces—among others—the risks attached to feeding whey dominant infant formula.
