As yet, the data from the provincial nutrition surveys cannot be aggregated to provide a national picture of food intake and nutrient status because results for all provinces are not available. Even when all data become available, the picture won't be truly national because the Territories aren't included. Children and older Canadians are not included. As well, the validity and usefulness of the aggregated data will be questionable, because by being spread over 10 years, temporal and regional differences will be confounded.
