Nutritional compositions containing milk-derived peptides and uses thereof

An age-specific nutritional composition system, the system comprising two or more nutritional compositions selected from the group consisting of:

• a first stage nutritional composition for infants from 0 to 3 months of age;
• a second stage nutritional composition for infants from 3 to 6 months of age;
• and
• a third stage nutritional composition for infants from 6 to 12 months of age,
• wherein the first stage nutritional composition comprises:
• a first carbohydrate component;
• a first fat or lipid component;
• and
• a first protein component, wherein the first protein component has a percentage molecular weight distribution in Daltons of:
• about 83 wt % to about 88 wt % of ≥5,000 Da;
• about 3 wt % to about 4 wt % of 4,999-2,000 Da;
• about 9 wt % 1,999-500 Da;
• and
• about 3 wt % to about 4 wt % ≤499 Da,
• wherein the second stage nutritional composition comprises:
• a second carbohydrate component;
• a second fat or lipid component;
• and
• a second protein component, wherein the second protein component has a percentage
• molecular weight distribution in Daltons of:
• about 83 wt % to about 88 wt % of ≥5,000 Da;
• about 3 wt % to about 4 wt % of 4,999-2,000 Da;
• about 7 wt % 1,999-500 Da;
• and
• about 3 wt % to about 4 wt % ≤499 Da, and
• wherein the third stage nutritional composition comprises:
• a third carbohydrate component;
• a third fat or lipid component;
• and
• a third protein component, wherein the third protein component has a percentage molecular weight distribution in Daltons of:
• about 83 wt % to about 88 wt % of ≥5,000 Da;
• about 3 wt % to about 4 wt % of 4,999-2,000 Da;
• about 5 wt % 1,999-500 Da;
• and
• about 3 wt % to about 4 wt % ≤499 Da.
