Quebec Longitudinal Study on Nutrition and Successful Aging
General objectives of the NuAge Study:
- To assess changes in dietary intakes of ageing men and women (foods, energy, macronutrients, micronutrients) and longterm exposure to functional foods from a qualitative and quantitative perspective;
- To assess the influence of longstanding and current dietary habits and evolving food choices on changes in numerous markers of physical and cognitive status, functional autonomy and social functioning;
- To assess the impact of age-related alterations in energy metabolism (utilisation and expenditure) and body composition, on changes in numerous markers of physical and cognitive status, functional autonomy and social functioning;
- To assess the impact of individual (biological, psychological, health, functional, behavioural) and environmental determinants on dietary intakes.
