Utilização de programação por metas como auxílio à tomada de decisão na composição da cesta básica de alimentos

Abstract

The purpose of this work is to present a goal programming formulation in an effort to evaluate the nutrients of the Brazilian food basket. Initially, this work reviews the nutrition’s concepts, highlighting the mains nutrients and their recommended dietary, an explanation about the functional foods, a description of the Brazilian food pyramid and there is a brief historical about the food basket set by law on 1938. Then, the multiple objectives decision making process is analyzed, focusing on the chosen methods for the work: goal programming. The model allows the decision maker to evaluate the following goals: meets the energetic values of the food basket with the desired values indicated on the Brazilian food pyramid; the adequacy of the nutrients intake; and food basket’s economic viability. The model was applied based on the dates from Fortaleza (CE), where three scenarios were generated build on the inputs and constraints alterations. According to the results, it was possible to verify the nutrients behavior as per the foods analyzed in each scenarios together with their costs. Mostly it was testified the nutritional inadequacy of the food basket set on the decree law no399 entered into force until today. Moreover, it was proved the possibility of a food combination more healthy with the same costs of the current food basket. Thereby, this study confirms the need of a reformulation of the food basket proposed to the Brazilians.
