Typical treatment for obesity and/or other chronic degenerative diseases should always include a dietetic approach. Diet success depends on several individual aspects, such as patient's personal motivation and attitudes; unfortunately, dietary planning does not always take into account the patient's cultural habits, which minimizes the impact of the nutritional intervention. The objective of the present study was to analyze and reduce the fat content of 10 representative recipes from Brazilian regional gastronomy, maintaining their acceptability and developing a standard protocol that could be used for improving nutritional content of any type of fat-rich traditional preparation. The recipes selected were tapioca flan (pudim de tapioca) and banana pie (torta de banana) from the northern region; hominy porridge (mungunzá) and corn cake (bolo de milho verde) from the northeast region; goianian pie (empadão goiano) and cassava cake (mané pelado) from the central west region; tropeiro beans (feijão tropeiro) and spiced chicken with rice (galinhada) from the southeast region; and carreteiro rice (arroz carreteiro) and ground corn with pork ribs 229 230 V. C. Ginani et al. (quirera lapiana) from the southern region. The preparations were submitted to a chemical composition analysis for humidity, protein, ashes, and total lipid content according to official methods of the Association of Analytical Chemists (AOAC, 1998) in duplicate. After the average nutrient content was determined, sensorial analysis was performed in order to investigate the acceptance rate of each preparation. The results were analyzed according to the hedonic scale of 7 points considering good acceptance those rates higher than 70%. Additionally, for statistical analysis the test F was applied, determining whether the samples were accepted significantly different to a level of 95% confidence. Some recipes had main ingredients with characteristically high lipid content, thus, in order to keep the regional characteristics of the preparation, those ingredients were not changed. Also, according to sensorial analysis, although there were some differences between the standard and modified samples, the recipes obtained similar acceptance rates (p > 0.05), except for carreteiro rice and banana pie recipes. In the case of the carreteiro rice, the acceptance of the modified recipe was greater than the standard and for the banana pie the inverse occurred, although the final acceptance of the modified recipe was greater than 70%. The results show that it is possible to conciliate healthy food and alimentary culture, once the adequate preparation technique is used, in particular those concerning the nutritional composition of the main ingredients (respecting the recipe characterization) and healthier methods of cooking. Moreover, those techniques can be applied for any regional/typical recipes in order to facilitate the patient's adherence to the prescribed diet plans or even for major actions concerning public health matters.
