Gut microbiota in infants
View Patent ↗The use of a whey predominant protein source and lactose in the manufacture of a nutritional composition for promoting the development of an early bifidogenic intestinal microbiota in infants fed with the nutritional composition wherein the nutritional composition has a protein content of less than 2.1 g protein/100 kcal and a phosphorus content of less than 40 mg/100 kcal.
1. A method of manufacturing a nutritional composition, the method comprising:
combining at least whey protein, a phosphorus source, lactose, water, a fat source having a ratio of n-6 to n-3 fatty acids ranging from about 5:1 to about 15:1, and an ingredient selected from the group consisting of lactoferrin, probiotics and a combination thereof to form a liquid composition, wherein the liquid composition has a phosphorus content of less than 40 mg/100 kcal and a protein content of less than 2.1 g protein/100 kcal, wherein the whey protein is a predominant protein of the protein content, the protein content includes partially hydrolyzed proteins having a degree of hydrolysis between 2 and 20%, and the whey protein has an extent of lysine blockage that is less than 10% by weight of lysine; and
spray drying or freeze drying the liquid composition to form a powder having a moisture content of less than about 5% by weight.
2. The method of claim 1 , wherein the nutritional composition is an infant formula.
3. The method of claim 1 , wherein the whey:casein ratio is at least 60:40.
4. The method of claim 1 , wherein the protein content of the composition is from 1.7 to 1.9 g/100 kcal.
5. The method of claim 1 , wherein the phosphorus content of the composition is between 26 and 33 mg/100 kcal.
6. The method of claim 1 , wherein the composition has a calcium ratio of calcium and phosphorus in the composition of between 1.8 and 2.0.
7. The method of claim 1 , wherein the composition has a lactose content of at least 10 g/100 kcal.
8. The method of claim 1 , wherein lactose constitutes 100% of the carbohydrate content of the composition.
9. A method for reducing the risk of subsequent development of an allergy in infants, the method comprising administering a nutritional composition to an infant wherein the nutritional composition comprises an ingredient selected from the group consisting of lactoferrin, probiotics and a combination thereof and has a phosphorus content of less than 40 mg/100 kcal, a fat source having a ratio of n-6 to n-3 fatty acids ranging from about 5:1 to about 15:1, and a protein content of less than 2.1 g protein/100 kcal, wherein whey protein is a predominant protein of the protein content, the protein content includes partially hydrolyzed proteins having a degree of hydrolysis between 2 and 20%, and the whey protein has an extent of lysine blockage that is less than 10% by weight of lysine.
10. The method of claim 9 , wherein the nutritional composition is an infant formula.
11. The method of claim 9 , wherein the whey:casein ratio is at least 60:40.
12. The method of claim 9 , wherein the protein content of the composition is from 1.7 to 1.9 g/100 kcal.
13. The method of claim 9 , wherein the phosphorus content of the composition is between 26 and 33 mg/100 kcal.
14. The method of claim 9 , wherein the composition has a calcium ratio of calcium and phosphorus in the composition of between 1.8 and 2.0.
15. The method of claim 9 , wherein the composition has a lactose content of at least 10 g/100 kcal.
16. The method of claim 9 , wherein lactose constitutes 100% of the carbohydrate content of the composition.
17. A method for promoting the development of an early bifidogenic intestinal microbiota in infants, the method comprising administering to an infant a nutritional composition comprising an ingredient selected from the group consisting of lactoferrin, probiotics and a combination thereof wherein the nutritional composition has a phosphorus content of less than 40 mg/100 kcal, a fat source having a ratio of n-6 to n-3 fatty acids ranging from about 5:1 to about 15:1, and a protein content of less than 2.1 g protein/100 kcal, wherein whey protein is a predominant protein of the protein content, the protein content includes partially hydrolyzed proteins having a degree of hydrolysis between 2 and 20%, and the whey protein has an extent of lysine blockage that is less than 10% by weight of lysine.
18. The method of claim 17 , wherein the nutritional composition is an infant formula.
19. The method of claim 17 , wherein the whey:casein ratio is at least 60:40.
20. The method of claim 17 , wherein the protein content of the composition is from 1.7 to 1.9 g/100 kcal.
21. The method of claim 17 , wherein the phosphorus content of the composition is between 26 and 33 mg/100 kcal.
22. The method of claim 17 , wherein the composition has a calcium ratio of calcium and phosphorus in the composition of between 1.8 and 2.0.
23. The method of claim 17 , wherein the composition has a lactose content of at least 10 g/100 kcal.
24. The method of claim 17 , wherein lactose constitutes 100% of the carbohydrate content of the composition.
