This article seeks to describe the viewpoint of purchasing food products from family farmers, analyzing their performance within the new guidelines of the Brazilian School Nutrition Program (PNAE). It is a critical assessment based on a review of the literature and the official data provided by the National Fund for the Development of Education/Ministry of Education relating to 2010. The program budget in 2010 was approximately R$2.5 billion and attended 45.6 million children, adolescents and adults. From the total amount, R$150,397,052.68 was allocated for the purchase of agricultural products from family farmers. In Brazil, 47.4% of the local councils acquired food products from family farmers for the Brazilian School Nutrition Program and the purchase percentage was, on average, 22.7%. Given the nature of recent legislation, other aspects should be explored in order to strengthen the compliance with the regulations in different Brazilian contexts and thus contribute both to local economic development and the provision of school meals which fulfill the principles of a healthy and adequate diet.

A presença da desnutrição, deficiência de micronutrientes, excesso de peso e outras doenças crônicas não transmissíveis coexistindo nas mesmas comunidades e, muitas vezes no mesmo domicílio, caracteriza a transição nutricional 1 . Esse fenômeno é traduzido em um dos maiores desafios para as políticas públicas no momento e exige um modelo de atenção à saúde pautado na integralidade do indivíduo com uma abordagem centrada na promoção da saúde.Diversos estudos têm demonstrado que o Brasil, assim como outros países em desenvolvimento, convive com a transição nutricional, determinada freqüentemente pela má-alimentação 2,3 . Ao mesmo tempo em que se assiste à redução contínua dos casos de desnutrição, são observadas prevalências crescentes de excesso de peso, contribuindo com o aumento das doenças crônicas não transmissíveis. A essas são associadas as causas de morte mais comuns atualmente. Segundo a Organização Mundial da Saúde (OMS), a hipertensão arterial e a obesidade correspondem aos dois principais fatores de risco responsáveis pela maioria das mortes e doenças no mundo 4 . No Brasil, as doenças cardiovasculares correspondem à primeira causa de morte há pelo menos quatro décadas, acompanhada de um aumento expressivo da mortalidade por diabetes e ascensão de algumas neoplasias malignas 5 .

The study of eating behavior has been much interest, as this is an essential element for the success of dietary interventions. In view of the complexity of the subject and the countless influences to which it is

Purpose. To assess the impact of a six-month stage-based intervention on fruit and vegetable intake, regarding perceived benefits and barriers, and self-efficacy among adolescents. Design. Randomized treatment-control, pre-post design. Subjects/Setting. Schools were randomized between control and experimental groups. 860 adolescents from ten public schools in Brasília, Federal District, Brazil were evaluated at baseline; 771 (81%) completed the study. Intervention. Experimental group received monthly magazines and newsletters aimed at promotion of healthy eating. Measures. Self-reported fruit and vegetable intake, stages of change, self-efficacy and decisional balance scores were evaluated at baseline and post-intervention in both groups. Analysis. The effectiveness of the intervention was evaluated using the analysis of covariance model (ANCOVA) and repeated measurement analysis by means of weighted least squares. Comparison between the proportions of adolescents who advanced through the stages during the intervention was performed using the Mantel-Haenszel chi-square test. Results. After adjusting for sex and age, study variables showed no modifications through the proposed intervention. There was no statistical difference in participant mobility in the intervention and control groups between the stages of change, throughout the study. Conclusion. A nutritional intervention based exclusively on distribution of stage-matched printed educational materials was insufficient to change adolescents' dietary behavior.
