[0067] In certain รุรุ, at least 20% of the พรีไบโอติก can ประกอบรวมด้วย galacto• oligosaccharide (GOS), (POX) or a ของผสม thereof. In an embodiment, the POX and GOS have a POX:GOS ratio of between about 9:1 and 1 :9. In another embodiment, the ratio of POX:GOScan be about 5:1 to 1 :5. In yet another embodiment, the ratio of POX:GOS can be between about 1 :3 and 1 :3. In further more particular รุรุ, the ratio can be about 1 :1 or 4:1. In another embodiment, the amount of the POX:GOScombination may be between about 2.0 g/L and 8.0 g/L. In a particular embodiment, the amount of the POX:GOScombination may be about 2 g/L of POX and 2 g/L of GOS. At least 20% of the พรีไบโอติก can ประกอบรวมด้วย galacto-oligosaccharide ("GOS"), โพลีเด็กซโตรส or a ของผสม thereof. The amount of each of GOS and/or โพลีเด็กซโตรส in the nutritional composition may, in an embodiment, be within the range of from about 1 .0 g/L ถึงประมาณ 4.0 g/L.
