Abstract

Disclosed are infant formulas comprising fat, protein, carbohydrate, vitamins, and minerals, including on an as-fed basis (A) at least about 5 mg/L of gangliosides, (B) at least about 150 mg/L of phospholipids, and (C) lactoferrin, and (D) at least about 70 mg/L of sialic acid, with at least about 2.5% by weight of the sialic acid as lipid-bound sialic acid. Also disclosed are methods of using the formula to reduce the risk of diarrhea infants, and to produce a gut microflora profile similar to that of breast-fed infants.

Claims

1. Infant formula comprising fat, protein, carbohydrate, vitamins, and minerals, including, on an as-fed basis:

(A) at least about 5 mg/L of gangliosides,

(B) at least about 150 mg/L of phospholipids,

(C) lactoferrin, and

(D) at least about 70 mg/L of sialic acid, with at least about 2.5% by weight of the sialic acid as lipid-bound sialic acid

2. An infant formula according to claim 1 wherein from about 50% to 100% by weight of the combination of gangliosides, phospholipids, lactoferrin, and total sialic acid is from an enriched whey protein concentrate source.

3. An infant formula according to claim 1 wherein the lipid-bound sialic acid represents from about 2.7% to about 5% by weight of the total sialic acid.

4. An infant formula according to claim 1 comprising, on an as-fed basis, (A) from about 7 mg/L to about 50 mg/L of gangliosides, (B) from about 200 mg/L to about 600 mg/L of phospholipids, and (C) from about 90 mg/L to about 250 mg/L of sialic acid.

5. An infant formula according to claim 1 comprising, on an as-fed basis, from about 50 mg/L to about 2000 mg/L of lactoferrin.

6. An infant formula according to claim 1 wherein the total phospholipid comprises at least 20% by weight of sphingomyelin.

7. An infant formula according to claim 6 wherein the phospholipid comprises sphingomyelin, phosphatidyl ethanolamine, phosphatidyl choline, phosphatidyl inositol, and phosphatidyl serine.

8. An infant formula according to claim 1 further comprising from about 0.05% to about 5% of a fructopolysaccharide.

9. An infant formula according to claim 1 wherein the formula contains less than about 0.5% free glycomacropeptides, on an as-fed basis.

10. An infant formula according to claim 1 wherein the infant formula is substantially free of phospholipids, egg phospholipids, and combinations thereof.

11. An infant formulas according to claim 1 wherein the infant formula comprises less than about 0.2% by weight of milk fat on an as-fed basis.

12. An infant formula according to claim 1 wherein the infant formula is a powder.

13. An infant formula according to claim 1 wherein the infant formula is a ready-to-feed liquid.

14. A method of reducing the risk of diarrhea in an infant, comprising

(I) preparing an infant formula comprising fat, protein, carbohydrate, vitamins, and minerals, including, on an as-fed basis:

(A) at least about 5 mg/L of gangliosides,

(B) at least about 150 mg/L of phospholipids,

(C) lactoferrin,

(C) at least about 70 mg/L of total sialic acid with at least about 2.5% by weight of the sialic acid as lipid-bound sialic acid,

(II) administering or instructing a caregiver to administer the formula to an infant.

15. A method according to claim 14 wherein the formula is administered as a sole source of nutrition.

16. A method according to claim 14 wherein from about 50% to 100% by weight of the combination of gangliosides, phospholipids, and sialic acid is from an enriched whey protein concentrate.

17. A method according to claim 14 wherein the lipid-bound sialic acid represents from about 2.7% to about 5% by weight of the total sialic acid.

18. A method according to claim 14, wherein the infant formula comprises, on an as-fed basis, (A) from about 7 mg/L to about 50 mg/L of gangliosides, (B) from about 200 mg/L to about 600 mg/L of phospholipids, and (C) from about 90 mg/L to about 250 mg/L of sialic acid.

19. A method according to claim 14 wherein the total phospholipid comprises at least 20% by weight of sphingomyelin.

20. A method according to claim 14 wherein the infant formula comprises less than about 0.2% by weight of milk fat on an as-fed basis.

21. A method according to claim 14 wherein the formula comprises less than 0.5% by weight of free glycomacropeptides on an as-fed basis.

22. A method of producing a gut microflora profile similar to that of breast-fed infants, said method comprising

(I) preparing an infant formula comprising fat, protein, carbohydrate, vitamins, and minerals, including, on an as-fed basis:

(A) at least about 5 mg/L of gangliosides,

(B) at least about 150 mg/L of phospholipids,

(C) lactoferrin,

(C) at least about 70 mg/L of total sialic acid with at least about 2.5% by weight of the sialic acid as lipid-bound sialic acid,

(II) administering or instructing a caregiver to administer the formula to an infant.

23. A method according to claim 22 wherein the formula is administered as a sole source of nutrition.

24. A method according to claim 22 wherein from about 50% to 100% by weight of the combination of gangliosides, phospholipids, and sialic acid is from an enriched whey protein concentrate.

25. A method according to claim 22 wherein the lipid-bound sialic acid represents from about 2.7% to about 5% by weight of the total sialic acid.

26. A method according to claim 22, wherein the infant formula comprises, on an as-fed basis, (A) from about 7 mg/L to about 50 mg/L of gangliosides, (B) from about 200 mg/L to about 600 mg/L of phospholipids, and (C) from about 90 mg/L to about 250 mg/L of sialic acid.
