In a 1981 landmark report, Doll and Peto1 estimated that 35% of US cancer deaths were attributable to dietary factors. This estimate was primarily based on the large differences in rates of specific cancers among countries and observations that these rates were strongly correlated with aspects of national food supplies. However, these authors acknowledged major uncertainties in responsible aspects of diet and the magnitude of impact.
