SIR, Observational studies have shown an inverse relationship between ingestion of dairy products and hyperuricaemia/gout [1]. Intervention studies have also shown that ingestion of dairy products has a short-term urate-lowering effect, and that a dairy-free diet leads to increased serum urate concentrations, by a magnitude of
0.06 mmol/l [2, 3].
Although dairy products are the principal dietary source of calcium, none of these studies have specifically assessed the influence of dietary calcium intake. Previous reports have implicated calcium metabolism in the regulation of serum
