RESUMO
Dietary patterns research is being pursued to provide a comprehensive way to characterize dietary exposures and explore diet-disease relationships. This paper outlines the need for further research into dietary pattern methodologies, and introduces papers presented at the Canadian Society for Clinical Nutrition-Canadian Society for Nutritional Sciences (now called Canadian Nutrition Society) Conference, held in Québec City in 2009. Themes that emerged include inconsistency of evidence linking diet patterns to risk of certain diseases, methodological issues around data collection and analysis, and the limitations of dietary pattern research for nutrition policy and recommendations.

A food intake pattern specifying amounts and types of food was created for Canada's revised food guide, Eating Well with Canada's Food Guide (2007), using a two-step modeling process. In step one, food composites were manipulated to develop a food intake pattern. The second step used the step one food intake pattern to create 500 simulated diets for each of 16 age and gender groups. The resulting nutrient content distributions were evaluated relative to Dietary Reference Intake reference values. The modeling cycled between these two steps until a satisfactory pattern was achieved. The final pattern reflects modeling, a review of associations between foods and chronic disease, and input received during consultation.
