The income of the Brazilian families has grown due to the adjustments of the minimum salary and to the application of Federal Government social programs, such as Bolsa Família. However these families still have difficulties to manage their salary to make it last for the whole month. The Research of the Family Budget (POF), conducted by the Brazilian Institute of Geography and Statistics (IBGE) suggests that the food security level - the right that everyone has to regular and permanent to quality and quantity foods - is lower in the families larger families, those with lower income, those weather the person that have the power of decision is a female and those with kids. Based in the appropriate literature, this research proposes nine hypotheses that were submitted and tested with 326 respondents, all resident in the State of Rio de Janeiro. The hypotheses try to identify the main motives that higher the satisfaction with food in the low income homes. The results mainly suggest that the satisfaction raises as income also rise and lower with the quantity of kids in the domicile. They still indicate that the forecast of the general satisfaction with food is based on the satisfaction with quantity and variety of food, as well as the variety of fruits and sweets. Although not verified initially, the results suggest that a more detailed study focusing the geographic location of the domiciles can bring more knowledge about the factors of satisfaction.
