Dietary intake of meat and meat-derived heterocyclic aromatic amines and their correlation with DNA adducts in female breast tissue

AbstractObjective:Development and validation of a short instrument to assess the dietary intake of heterocyclic aromatic amines (HCA).Design:At first, a longer instrument asking for the consumption of 11 meat and fish items and different preparation methods was developed. The degree of browning of these foods was assessed by means of photos. This questionnaire was sent to 500 participants of the European Prospective Investigation into Cancer and Nutrition (EPIC) in Heidelberg, Germany, in June 1999. Using 385 completed questionnaires, a short questionnaire was developed covering just seven food items, which was sent to the participants again. Of these, 344 were returned with in four months. Total dietary intake of HCA as well as the intake of different HCA were calculated and compared between both versions.Results:Median dietary intake of total HCA was 103ng day−1as assessed with the short version; the intakes of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP),2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) and 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx) were 63, 34 and 2ng day−1, respectively. These results did not differ significantly from those obtained with the longer version. Spearman rank correlation coefficients between the long and the short version ranged from 0.46 to 0.6. In quartile cross-classification, 70–78% of the participants were assigned into the same or an adjacent quartile while categorisation into opposite quartiles was ≤3.5%.Conclusion:The short version of the HCA questionnaire demonstrates good validity compared with the longer version. The intake of HCA as assessed with the short questionnaire is comparable to that found in other studies using a short questionnaire.

Risk Of Cancer

Frequent consumption of thermally processed meat was classified by the International Agency for Research on Cancer to directly carcinogenic agents for humans. During the heat treatment of high protein food, mutagenic and carcinogenic, as well as neurotoxic heterocyclic aromatic amines are formed. Epidemiological studies confirm that exposure to some of these compounds may increase the risk of cancer in humans, especially the colon cancer. Most heterocyclic amines contain fried and grilled meat products, and the lowest content of these compounds can be found in boiled and slightly baked dishes. The use of spices and vegetable additives with antioxidant properties allows to obtain dishes with reduced content of these xenobiotics. An effective way to reduce human exposure to cancerogenic amines may be simultaneous consumption, together with meat dishes, products containing fiber which can adsorb molecules of heterocyclic amines in the gastrointestinal tract, as well as enrichment of the diet in the crucifers plants, as isothiocyanates released from them can inhibit the metabolic activation processes of heterocyclic amines. Raising the public awareness of the formation of mutagenic and carcinogenic compounds, including heterocyclic aromatic amines, during the intensive heat treatment of high protein food, as well as the dissemination of knowledge on the conditions regarding the preparation of dishes with reduced content of such compounds could become one of the components of cancer prevention programs in Poland.

AbstractSince Dr. Sugimura’s discovery of heterocyclic aromatic amines (HAA) in broiled fish, many epidemiological studies have been conducted to investigate their role in human cancers, often focusing on colorectal cancer. The difficulty in measuring HAA exposure from meat and fish intake in these studies has resulted in inconsistent findings. Because studying individuals who may be particularly susceptible to the carcinogenic effects of HAA might facilitate the demonstration of a link with cancer, multiple studies have focused on individuals with the high activity phenotype for CYP1A2 and/or NAT2, the two main metabolic enzymes involved in the bioactivation of HAA. These investigations have also yielded inconsistent results. Two recent large pooled analyses of colorectal cancer studies have helped clarify the overall evidence. One was conducted in whites and reported no interaction of red meat intake and NAT2 genotype on risk in Whites. The other was conducted in Japanese and African Americans, two populations with high rates of the disease and a prevalence of the at-risk rapid NAT2 phenotype 10- and 2-fold greater than in whites, respectively. In those groups, a significant interaction was found, with the association of red meat with colorectal cancer being strongest among individuals with the rapid NAT2 phenotype, intermediate among those with the intermediate phenotype and not significant among those with the slow NAT2 phenotype. Recent research on biomarkers has focused on PhIP hair content, as a marker of exposure to HAA, and on DNA adducts using new sensitive quantitative methods, as markers of early biological effects. These advances, when brought to bear, may contribute greatly to the further elucidation of the carcinogenicity of HAA in humans.
