The invention relates to nutritional compositions comprising a mixture of non-digestible oligosaccharides comprising short-chain fructo-oligosaccharides, long-chain fructo-oligosaccharides and 2′-fucosyllactose that have been shown to provide a beneficial short-chain fatty acids profile and intestinal bifidobacteria population. The nutritional compositions are for infants and young children and are in particular beneficial for infants or young children suffering from food allergy, in particular cow's milk protein allergy.
