The invention pertains to powdered nutritional compositions comprising large lipid globules and micronized carbohydrate or carbohydrate microcrystals. Preferably the nutritional composition is an infant or follow on formula or a growing up milk. The invention also pertains to the use of micronized carbohydrate or carbohydrate microcrystals for improving flow and reducing cohesiveness of a powdered nutritional composition with large lipid globules.
