Serum zinc and copper in relation to diet in 3- to 18-year old Finnish girls and boys.
Serum zinc (S-Zn) and copper (S-Cu) concentrations were measured and compared with data on dietary intakes of energy, protein, fat, carbohydrate, zinc, copper, phosphorus, calcium, iron, sucrose, vitamin C and dietary fibre, collected by means of the 48-h recall method in 1634 3-, 6-, 9-, 12-, 15- and 18-year old girls and boys. The intake of fibre was inversely related to S-Cu but not to S-Zn. None of the dietary components measured seemed to have a distinct negative effect on S-Zn, indicating that such factors were present at levels too low to affect S-Zn, or associated with factors favouring Zn bioavailability. Factors decreasing the bioavailability of Zn or Cu may especially affect adolescent girls whose average intakes of both Zn and Cu were low.
