  3. Based on a questionnaire used by the Danish Cancer Registry Validated in several ways (1-4) Standard portion sizes from the Scandinavian Journal of Nutrition (5) 360 different food items (6). (1) Tjonneland A. et al., Int J Epidemiol 1991;20:906-12 (2) Friis S et al., J Clin Epidemiol 1997;50:303-11 (3) Mikkelsen, T. B. et al. Public Health Nutr 2006;9:771-778. (4) Mikkelsen, T. B. et al.
