- Background and objectives: Few studies have investigatedthe association between whole-grain intake and colorectal cancer.Whole-grain products are one of the dietary items proneto measurement errors, making the use of objective measures,such as biomarkers, highly relevant. The objective of the studywas to investigate the association between biomarkers ofwhole-grain intake, alkylresorcinols, and colorectal cancer ina nested case-control study within the European ProspectiveInvestigation into Cancer and Nutrition (EPIC). Methods: We included 1372 first incident colorectal cancercases and 1372 individually matched controls and calculatedthe incidence rate ratios (IRR) for overall and sub-sites of colorectalcancer using conditional logistic regression adjusted forpotential confounders.Results: Plasma total alkylresorcinol concentrations werenot associated with risk of overall colorectal cancer, proximalcolon cancer or rectal cancer. However, high plasma total alkylresorcinolconcentrations were statistically significantly associatedwith lower incidence of cancer located in the distal (leftor descending) part of the colon. Adjusted IRR of distal coloncancer for highest versus lowest quartile of plasma alkylresorcinolwas 0.48 (95% confidence interval = 0.28 to 0.83). Furthermore,we observed an inverse association with colon cancerfor the Scandinavian part of the participants. Alkylresorcinolsmay be more appropriate as biomarkers in Middle Europe andScandinavia i.e. in areas where whole grains are regularly consumed.Conclusions: Whole-grain intake, assessed by alkylresorcinols,was associated with a lower incidence of distal coloncancer. Alkylresorcinols seem useful as objective biomarkersof whole-grain intake in populations where whole-grains are astaple part of the diet.

- Background and objectives: In the recent years a trendwithin nutrition epidemiology has been to assess overall dietaryquality, often by identifying dietary patterns. The HELGAstudy population is based on samples of existing cohorts fromthe three Scandinavian countries. All three cohorts are part ofthe EPIC study. The aim of this study is to find a typical wholegrain pattern in Scandinavia and see if the pattern is similar inthe three countries.Methods: The associations among the variables were investigatedby factor analysis.Results: Both Norway and Sweden had two breakfast patternsand one dinner pattern. Both the countries had a healthybreakfast pattern including food items commonly consideredhealthy, such as fruit, yoghurt and breakfast cereals. However,coarse bread was the main item in a more traditional pattern for Norway, while it was a part of the healthy pattern inSweden. The second breakfast pattern in Sweden included unhealthyitems like white bread, cakes, sweets, soft drinks andalcohol. The dinner pattern was almost equal in Sweden andNorway. Denmark differed from the other Scandinavian countriesconcerning dietary patterns. Only one breakfast patternwas found. This pattern had some similarities with the traditionalNorwegian pattern, but scored high on all whole grainitems while in Norway only wheat had a high score. Two dinnerpatterns are seen for Denmark, the healthier one includesfruit and vegetables, fish and poultry, the second includes meatand meat products, ice cream and alcohol.Conclusions: When comparing dietary patterns from thethree Scandinavian countries, we find both differences andsimilarities. The main whole grain item used in Norway andSweden seems to be wheat, while rye is more dominant in Denmark.

- Background and objectives: Whole grains are a good sourceof dietary fibre, but beneficial effects might also stem fromother components of the grain. Very few studies exist on intakeof whole grains and incidence of stomach and oesophagealcancer, but studies on dietary fibre and these cancers suggesta protective effect. The objective of this work was to study theassociation between intake of whole grains and incidence ofoesophageal and gastric cancer. Methods: The Helga cohort has 120 000 participants fromthe Norwegian Women and Cancer study, The Northern Sweden Health and Disease study and the Danish Diet, Cancerand Health study, recruited in 1992-1999. After exclusions, 112cases of oesophageal cancer, 185 cases of gastric cancer and 113700 other cohort members were included in the analyses. Theyprovided dietary information in semi-quantitative FFQs at baseline,and also information about other risk factors. Cancer information was obtained by linkage to the respective cancerregistries. The association between whole grain intake and cancerwas analysed with Cox proportional hazards models. Results: The median whole-grain intake was 47.4 g/day(5th-95th percentile: 13.3-101.1) in the non-cases, 37.5 g/day(10.8-87.2) in oesophageal cancer cases, and 45.1 g/day (8.1-99.1) in gastric cancer cases. A decreased risk of oesophagealcancer was observed, HR=0.83 (CI 0.69-0.99) p=0.04 per 20g of whole grains. The HR for highest compared with lowesttertile of intake was 0.56 (0.32-0.97) p=0.03. The analyses wereadjusted for country, smoking status, age at baseline, sex, processedmeat, alcohol and vitamin C. No association was foundfor whole grains and gastric cancer.Conclusion: In this study, higher intake of whole grains wasassociated with lower risk of oesophageal cancer.
