“…Does epidemiological evidence support such a conclusion? High mortality rates due to esophageal carcinomas were seen in Japanese population groups with a high consumption of tea gruel (Segi, 1975;Hirayama, 1979;Shimizu et al, 1980), amoilg Caribbean island residents accustomed to drinking a great variety of tanninkatechinrich herbal teas (Morton, 1972;Kapadia et al, 1983), matte-drinking gauchos of Argentina and Brazil (Prudente, 1963), chewers of phenolic-containing betel nuts (Jayant et al, 1977;Jussawalla and Deshpande, 1971;Jussawalla et al, 1980), and heavy consumers of strong teas ingested at excessive temperatures in Kazakhstan, USSR (Kolicheva, 1980) or in the Caspian region of Iran (Joint Iran-IARC Study Group, 1977). Compared to the high incidence of esophageal cancers among groups consuming excessive amounts of phenolic-containing items, the mortality rates for stomach cancers are relatively low, as in the case of tea gruel-eating Japanese (Segi, 1975), betel quid-chewing Gujratis (Jussawalla et al, 1980), and the populations of several industrialized countries with high tea consumption (Stocks, 1970).…”
