In the past priorities in pediatrics were dominated by different urgent medical problems as prematurity, infections, heart malformations and cancer. The growing impact of childhood overfeeding to health issues is not only visualized by overweight children attending open public i.

Sensitivity to meat protein intake and hyperoxaluria in idiopathic calcium stone formers.

Background: High protein intake is an accepted risk factor for renal stone disease. Whether meat protein intake affects oxaluria, however, remains controversial in healthy subjects and in stone formers. This study was designed (1) to test the oxaluric response to a meat protein load in male recurrent idiopathic calcium stone formers (ICSFs) with and without mild metabolic hyperoxaluria (MMH and non-MMH, respectively), as well as in healthy controls, and (2) to seek for possible disturbed vitamin B(6) metabolism in MMH, in analogy with primary hyperoxaluria.
