What are the main research lines that will support the implementation of the National Policy on Food and Nutrition?

The research lines will be developed according to the norms of the National Commission of Ethics in Human Research.
The research lines will clarify particular and general aspects of some problems, evaluate the contribution of causal factors involved, and indicate the most appropriate measures for their control.
The research lines will focus on the problem of protein-energy malnutrition, the epidemiology of anemia and hypovitaminosis A, the relationship between chronic non-communicable diseases and diet, the cost-benefit and cost-effectiveness of programs and actions, and the prevalent nutritional deficiencies in the country.
The research lines will allow the development of national tables on the nutritional composition and value of foods and the main culinary preparations, as well as the establishment of regionalized dietary patterns for all age groups.
