Abstract

Disclosed are infant formulas and corresponding methods of using them to promote retinal health and vision development in infants. The formulas, which are free of egg phospholipids and comprise fat, protein, carbohydrate, vitamins, and minerals, including docosahexaenoic acid and, on a ready-to-feed basis, at least about 50 mcg/liter of lutein, wherein the weight ratio of lutein (mcg) to docosahexaenoic acid (mg) is from about 1:2 to about 10:1. The formulas are also believed to be especially useful in reducing the risk of retinopathy of prematurity in preterm infants.

Claims

1. An infant formula comprising fat, protein, carbohydrate, vitamins, and minerals, including docosahexaenoic acid and, on a ready-to-feed basis, at least about 50 mcg/liter of lutein, wherein the weight ratio of lutein (mcg) to docosahexaenoic acid (mg) is from about 1:

2 to about 10;

1 and the formula is free of egg phospholipids.

2. The infant formula of claim 1 wherein the composition comprises from about 50 to about 1150 mcg/liter of added lutein.

3. The infant formula of claim 1 wherein the formula comprises from about 100 to about 200 mcg/liter of lutein.

4. The infant formula of claim 1 wherein the formula comprises from about 100 to about 200 mcg/liter of lutein.

5. The infant formula of claim 1 wherein the weight ratio of lutein (mcg) to docosahexaenoic acid (mg) is from about 1.5:

1 to about 10;

1.

6. The infant formula of claim 1 wherein the weight ratio of lutein (mcg) to docosahexaenoic acid (mg) is from about 2:

1 to about 5;

1.

7. The infant formula of claim 1 wherein the formula has a caloric density of from 20 to 30 kcal/fluid ounce.

8. The infant formula of claim 1 wherein the formula comprises a combination of free lutein and zeaxanthin from a single source, that source being a crystalline extract of Tagetes erecta in which the free lutein represents from 85% to 95% by weight of the combination and the free zeaxanthin represents from about 5% to about 15% by weight of the combination.

9. The infant formula of claim 1 wherein the formula is a powder.

10. The infant formula of claim 1 wherein the formula is a liquid.

11. The infant formula of claim 1 wherein the lutein comprises at least 25% by weight of added lutein.

14. A method to reduce the risk of retinopathy of prematurity in preterm infants, said method comprising administering to a preterm infant in need thereof a formula according to claim 1 to provide the infant from about 7 to about 300 mcg/kg/day of lutein.

15. A method to reduce the risk of retinopathy of prematurity in preterm infants, said method comprising administering to a preterm infant in need thereof a formula according to claim 1 to provide the infant from about 14 to about 220 mcg/kg/day of lutein.

16. A method to promote retinal health and vision development in infants, said method comprising administering to an infant in need thereof a formula according to claim 1 to provide the infant from about 7 to about 300 mcg/kg/day of lutein.

17. A method to promote retinal health and vision development in infants, said method comprising administering to an infant in need thereof a formula according to claim 1 to provide the infant from about 7 to about 300 mcg/kg/day of lutein.

12. An infant formula comprising, on a ready-to-feed basis,

(a) from about 54 to about 108 gm/liter of carbohydrate,

(b) from about 20 to about 54 gm/liter of fat,

(c) from about 7 to about 24 gm/liter of protein,

(d) from about 100 to about 200 mcg/liter of lutein, and

(e) docosahexaenoic acid,

wherein the weight ratio of lutein (mcg) to docosahexaenoic acid (mg) is from about 2:

1 to about 5;

1 and the formula is free of egg phospholipids.

13. The infant formula of claim 12 wherein the formula comprises a combination of free lutein and zeaxanthin from a single source, that source being a crystalline extract of Tagetes erecta in which the free lutein represents from 85% to 95% by weight of the combination and the free zeaxanthin represents from about 5% to about 15% by weight of the combination.
