The association of macro- and micronutrient intake with growth hormone secretion.

ABSTRACT:

Context

Growth hormone (GH) is known to be nutritionally regulated, but the effect of dietary composition on detailed GH secretion parameters has not previously been comprehensively evaluated.

Objective

The objective of the study was to determine whether specific macro- and micronutrients are associated with discrete parameters of GH secretion among subjects with wide ranges of body mass index.

Design

Detailed macro- and micronutrient intake was assessed by 4-day food records while GH secretion was assessed by standard stimulation testing in 108 men and women in one study (Study 1), and by overnight frequent blood sampling in 12 men in another study (Study 2).

Results

Peak stimulated GH was positively associated with vitamin C (r=+0.29; P=0.003), dietary fiber
