Diet and renal stones in 72 areas in England and Wales

Geographical differences in emergency admission rates for renal stones and colic in England and Wales have been shown to correlate with the incidence of renal stones determined from case registers. The rates in 72 areas were related to per capita consumption of different foods, measured from household food purchases. There was an inverse relation with consumption of dietary fibre and all cereal foods. Differences in adult diet are not, however, the major determinants of the geographical variations in renal stone incidence within Britain.
