Abstract

A method of increasing the salivary sialic acid content of a mammal is described which involves administering to the mammal casein glycomacropeptide in an amount sufficient to increase the salivary sialic acid content of the mammal.

Claims

1. A method of increasing the salivary sialic acid content in a mammal that is in need of increasing salivary sialic acid content, the method comprising administering to the mammal casein glycomacropeptide in an amount sufficient to increase the salivary sialic acid content in the mammal.

2. The method according to claim 1, wherein the mammal is between about 1 day and about 4 years of age.

3. The method according to claim 1, wherein the mammal is a neonatal mammal.

4. The method according to claim 1, wherein the mammal that is in need of increasing salivary sialic acid content is a mammal in which at least a portion of its nutritional requirement has been supplied by a formula having less than about 100 mg/L of sialic acid.

5. The method according to claim 4, wherein the mammal that is in need of increasing salivary sialic acid content is a mammal in which substantially all of its nutritional requirement has been supplied by administration of a formula having less than about 100 mg/L of sialic acid.

6. The method according to claim 5, wherein a major part of the protein contained in the formula is soy protein or cow'"'"'s milk protein.

7. The method according to claim 6, wherein at least about 75% by weight of the protein contained in the formula is soy protein or cow'"'"'s milk protein.

8. The method according to claim 6, wherein substantially all of the protein contained in the formula is soy protein or cow'"'"'s milk protein.

9. The method according to claim 1, wherein the mammal that is in need of increasing salivary sialic acid content is a mammal in which its nutritional requirement has been supplied by a diet providing sialic acid in an amount that is lower than would normally be obtained from breastfeeding.

10. The method according to claim 9, wherein the diet providing a lower amount of sialic acid than would normally be obtained from breastfeeding comprises a liquid formula having a sialic acid content that is below about 100 mg/L.

11. The method according to claim 9, wherein the diet providing a lower amount of sialic acid than would normally be obtained from breastfeeding comprises a liquid formula having a sialic acid content that is below about 200 mg/L.

12. The method according to claim 1, wherein administering the formula comprises enteral administration.

13. The method according to claim 1, wherein the formula is an infant formula.

14. The method according to claim 1, wherein the formula is a nutritionally complete infant formula comprising carbohydrate, lipid, and protein.

15. The method according to claim 14, wherein the protein comprises a material that is selected from cow'"'"'s milk protein, soy protein, or a mixture thereof.

16. The method according to claim 1, wherein the formula comprising casein glycomacropeptide is administered in an amount sufficient to provide at least about 100 mg/kg-day of sialic acid to the mammal.

17. The method according to claim 1, wherein the formula comprising casein glycomacropeptide is administered in an amount sufficient to provide at least about 200 mg/kg-day of sialic acid to the mammal.

18. The method according to claim 1, wherein the formula comprises a liquid having a sialic acid concentration of at least about 200 mg/liter.

19. The method according to claim 18, having a sialic acid level of at least about 300 mg/liter.

20. The method according to claim 18, having a sialic acid level of at least about 600 mg/liter.

21. The method according to claim 1, comprising a formula having a total protein content of between 12 and 16 grams/liter of which no more than 40% by weight is provided by casein glycomacropeptide.

22. The method according to claim 21, wherein the formula comprises a total protein content of between 13 and 15 grams/liter of which no more than 30% by weight is provided by casein glycomacropeptide.

23. The method according to claim 1, wherein the casein glycomacropeptide comprises a casein glycomacropeptide having an enhanced concentration of sialic acid.

24. The method according to claim 23, wherein the casein glycomacropeptide having an enhanced concentration of sialic acid comprises high-sialic acid casein glycomacropeptide with reduced threonine.

25. The method according to claim 24, wherein the formula has a total protein content of between 13 and 15 grams/liter of which no more than 30% by weight is provided by a casein glycomacropeptide having an enhanced concentration of sialic acid and having a threonine content of not over 10 grams/16 grams nitrogen.

26. The method according to claim 1, wherein the formula has a total protein content of about 14 grams/liter of which not over 4% by weight is threonine and having a sialic acid content of at least 400 mg/liter.

27. The method according to claim 1, further comprising measuring the salivary sialic acid content of the mammal following the administration of the casein glycomacropeptide.

28. A method of increasing salivary sialic acid content in a mammal, the method comprising:

determining whether the mammal is one that is in need of increasing salivary sialic acid content; and

, if so

administering to the mammal a formula comprising casein glycomacropeptide in an amount sufficient to increase salivary sialic acid content in the mammal.
