The present disclosure relates to a lipid source for nutritional compositions, comprising an enriched lipid fraction which comprises structured fat globules. The enriched lipid fraction provides fat globules having a desired size and fatty acid composition and may be stabilized by components such as phospholipids, cholesterol, milk-fat globule membrane protein and combinations thereof. Additionally, the disclosure relates to methods of supporting lipid digestion in a pediatric subject by providing a nutritional composition comprising an enriched lipid fraction having structured fat globules that are more accessible to lipases. The chemical composition, size and structure of the fat globules may improve digestion. The disclosed nutritional compositions may provide additive and or/synergistic beneficial health effects.
