This paper aims through a case study to show how the diversified agriculture, that is practiced by rural farms households, could be an alternative answer to the food insecurity problems of these populations, as well as the environment preservation, where it is joined at the adapted food education programs, where possible, to local tastes and customs. For this purpose we carried out a census and interviewed the families who are farmers in study area. These interviews were made by with an eight modules questionnaire. One of them is the Brazilian Food Insecurity Scale which allowed us to know the food insecurity level of these families. Later, we elaborated a database in the software Statistical Package for Social Sciences - SPSS with the questionnaire variables and then started the statistical analysis and the situational diagnosis according to the FODA method (strengths, opportunities, weaknesses and threats) and the interpretation of data to so finally present the survey results. Finally, we founded that there was a positive relationship between food security and the degree of the production diversification; that the families eating habits could be improved through nutrition education programs; and the apparent positive effects of land redistribution in self- support household food.
