High intakes of skimmed milk, but not meat, increase serum IGF-I and IGFBP-3 in eight-year-old boys
Objective : To examine whether a high protein intake (PI) from either milk or meat, at a level often seen in late infancy, could increase s-IGF-I and s-IGF-I/s-IGFBP-3 in healthy, prepubertal children. IGF-I levels are positively associated with growth velocity in children and some studies suggest t...

Summary: | Objective
: To examine whether a high protein intake (PI) from either milk or meat, at a level often seen in late infancy, could increase s-IGF-I and s-IGF-I/s-IGFBP-3 in healthy, prepubertal children. IGF-I levels are positively associated with growth velocity in children and some studies suggest that a high animal PI can stimulate growth. During protein deprivation IGF-I decrease, but it is unknown whether a high PI can increase s-IGF-I in well-nourished children.
Design
: In all, 24 8-y-old boys were asked to take either 1.5 l of skimmed milk (
n
=12) or the same amount of protein as 250 g low fat meat (
n
=12) daily for 7 days. The remaining diet they could choose freely. At baseline and after 7 days, anthropometrical variables were measured, diet was registered (3-day weighed records), and s-IGF-I and s-IGFBP-3 (RIA) were determined after fast.
Results
: PI increased by 61% in the milk group to 4.0 g/kg/day (
