Abstract:
:To elucidate the effect of intake of mutagenic and/or carcinogenic pyrolysis products of proteins and amino acids on carcinogenesis in man, we have undertaken two epidemiologic cohort studies: one concerning the possible association of broiled fish consumption with cancer and the other concerning the cancer mortality among Japanese Seventh-Day Adventists. The main findings of these studies are described.
