Abstract
Objective:
To compare the short-term effect of a high milk and a high meat intake, identical in protein amount, on bone turnover during prepuberty.
Setting:
A University Department.
Design and Subjects:
From 28, randomly recruited, 8-year-old boys, first 14 were assigned to the milk group and next 14 to the meat group. In each group, 12 boys finished the dietary intervention.
Intervention:
Milk (1.5 l/day) and meat (250 g/d), both containing ∼53 g of protein, were given together with the habitual diet for 7 days. At baseline and day−7, serum osteocalcin (s-OC), bone-specific alkaline phosphatase (s-BAP) and C-terminal telopeptides of type I collagen (s-CTX) were measured (immunoassay) and dietary intake was estimated (a 3-day weighted food record).
Results:
Baseline s-OC, s-BAP and s-CTX were not significantly different between the groups. After 7 days, the average protein intake increased in both groups by 47.5 g; the milk group had higher (P<0.0001) calcium intake; s-OC and s-CTX decreased (P⩽0.04) in the milk group (−30.9%; −18.7%, respectively) compared with the meat group (+6.4%; −1.0%, respectively) and s-BAP decreased (P=0.06) both in the milk (−3.9%) and the meat group (−7.5%).
Conclusions:
At the equal protein intake, milk, but not meat, decreased bone turnover in prepubertal boys after 7 days. This effect was probably due to some milk-derived compounds, rather than to the total protein intake. Future studies should elucidate the mechanism(s) of milk-related decline of bone turnover and its relevance for peak bone mass during growth.
