  • Known mutagens and carcinogens in the dict were compiled and the risk of cancer was estimated on the basis of average exposure Ievels in Switzerland and carcinogenic potencies from rodent bioassays. The analysis showed that, except for a1cohol, the sum of all known dietary carcinogens could only explain a few percent of the cancer deaths attributed by epidemiologists to dietary factors. The discrepancy was explained by a "carcinogenicity" of excess macronutrients. This hypothesis was based on an evaluation of dietary restriction experiments inKnown mutagens and carcinogens in the dict were compiled and the risk of cancer was estimated on the basis of average exposure Ievels in Switzerland and carcinogenic potencies from rodent bioassays. The analysis showed that, except for a1cohol, the sum of all known dietary carcinogens could only explain a few percent of the cancer deaths attributed by epidemiologists to dietary factors. The discrepancy was explained by a "carcinogenicity" of excess macronutrients. This hypothesis was based on an evaluation of dietary restriction experiments in rats and mice, where a dramatic reducing effect on spontaneaus tumour formation was seen. From these experiments, a "carcinogenic potency" was deduced for food in excess (TD50 approximately 16 g/kg per day). Ovemutrition in Switzerland was converted into excess food intake and the cancer risk estimated on the basis ofthe TD50 value.
