In summary then we can say that diet in Ireland is changing continuously, that the patterns as documented in diet are consistent with the epidemiological patterns of the major chronic diseases, although predictions for the future will be complex because of both positive and negative changes in diet behaviours. The major influences on diet relate to changes in the food chain, which have been enormous in 100 years; at consumer level, health concerns appear to be one of many considerations in food choices. We need a more consistent, comprehensive database in order to make meaningful inferences about diet and health. Furthermore, to be really useful such databases should include both quantitative and qualitative information.
