TABLE 1.

Milk concentrations assumed when setting the AI for the first 6 mo of life compared to value in milk of deficient infants and percent of AI this represents¹

Nutrient	Milk concentration/L assumed for setting AI	Milk concentration reported for deficient infants (reference)	AI consumed by deficient infants, %
Thiamin, mg	0.21	0.16 (16)2	60
Riboflavin, mg	0.35	0.21 (16)3	53
Vitamin B-6, mg	0.13	0.10 (16, 18, 59)4	80
Vitamin B-12, μg	0.42	<0.055	16
Choline, mg	160	90 (48)6	56

¹Milk intake was assumed to be 780 mL/d.

²Study selected because of larger sample size. Note that breast milk concentration was higher than in India (18) and Thailand (19).

³Selected based on largest sample size and clear evidence of deficiency in mothers and infants.

⁴Similar values from these studies in India, The Gambia and Egypt.

⁵Selected because of large sample size and evidence of deficiency in mothers and infants (44).

⁶Based on data from the only available low income country (Ecuador). Forty percent of samples were lower than this value. Infant choline status was not assessed.
