  • Self-Reported Whole-Grain Intake and Plasma Alkylresorcinol Concentrations in Combination in Relation to the Incidence of Colorectal Cancer
  • 2014
  • Ingår i: American Journal of Epidemiology. - : Oxford University Press. - 0002-9262 .- 1476-6256. ; 179:10, s. 1188-1196

    • Self-reported food frequency questionnaires (FFQs) have occasionally been used to investigate the association between whole-grain intake and the incidence of colorectal cancer, but the results from those studies have been inconsistent. We investigated this association using intakes of whole grains and whole-grain products measured via FFQs and plasma alkylresorcinol concentrations, a biomarker of whole-grain wheat and rye intake, both separately and in combination (Howe's score with ranks). We conducted a nested case-control study in a cohort from a research project on Nordic health and whole-grain consumption (HELGA, 1992-1998). Incidence rate ratios and 95% confidence intervals were calculated using conditional logistic regression. Plasma alkylresorcinol concentrations alone and Howe's score with ranks were inversely associated with the incidence of distal colon cancer when the highest quartile was compared with the lowest (for alkylresorcinol concentrations, incidence rate ratio = 0.34, 95% confidence interval: 0.13, 0.92; for Howe's score with ranks, incidence rate ratio = 0.35, 95% confidence interval: 0.15, 0.86). No association was observed between whole-grain intake and any colorectal cancer (colon, proximal, distal or rectum cancer) when using an FFQ as the measure/exposure variable for whole-grain intake. The results suggest that assessing whole-grain intake using a combination of FFQs and biomarkers slightly increases the precision in estimating the risk of colon or rectal cancer by reducing the impact of misclassification, thereby increasing the statistical power of the study.

  • Aboriginal food security in the Arctic : a Utopia or a matter of attitude?
  • 2015
  • Ingår i: EurSafe News. - Voorburg, Netherlands : European Society of Agricultural and Food Ethics. ; 17:3, s. 2-4
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • In the discussion on food security in the Arctic, food sovereignty is increasingly emphasized. In many cases, the vision of aboriginal food security equals a the vision of a situation of unchanged access subsistence species from time to time. Unfortunately, this is a very unlikely scenario in the Arctic.

  • Whole Grain Intake and Survival Among Scandinavian Colorectal Cancer Patients
  • 2014
  • Ingår i: Nutrition and Cancer. - : Routledge. - 0163-5581 .- 1532-7914. ; 66:1, s. 6-13
  • Tidskriftsartikel (refereegranskat)abstract
    • To our knowledge, no studies of associations between intake of whole grain (WHG) and survival of colorectal cancer have been published, despite evidence that dietary fiber, and to some extent WHG, are associated with lower risk of colorectal cancer. Scandinavia is an area where the WHG consumption traditionally is high. We performed a case-only (N = 1119) study in the Scandinavian HELGA cohort of pre-diagnosis WHG intake (total WHG, WHG wheat, WHG rye, and WHG oats) and survival of colorectal cancer. Cox regression analyses were used to study the associations, both in categorical and continuous models, stratified by location (proximal, distal, rectum) and country. No evidence of an association was found, neither for total WHG intake (hazard ratio = 1.32, 95% confidence interval: 0.88-1.97 lowest vs. highest tertile, adjusted for age at diagnosis, metastasis status, smoking, folate, margarine, and energy), nor for specific grains. Prediagnosis consumption of WHG does not seem to improve survival of colorectal cancer in subjects diagnosed within this prospective population-based Scandinavian cohort.
