OBJECTIVE: The purpose of this research is to evaluate the nutritional adequacy of meals served and consumed by soldiers in a construction unit (army and civil employees) of the Brazilian Army Construction. METHODS: Body mass index, fat percentage (bioimpedance) and the physical activity level were evaluated. Furthermore, the nutritional evaluation of meals offered and consumed by soldiers was evaluated, in relation to the macronutrients, sodium, fibers and total energetic value. RESULTS: Through the results, we verified that 76% of the soldiers were eutrophic, and that the population's energetic requirement was approximately 3.600 kcal. We verified that the energetic consumption of this population was below the required value (3.200 kcal) and with inadequacy regarding the distribution of macronutrients: percentage of carbohydrates above the recommended one, percentage of lipid below the minimum value recommended and percentage of proteins within the recommendation. Moreover, the amount of fibers was in accordance to the standards; however, there was an excessive amount of sodium, which may put this population in danger. CONCLUSION: We concluded that it is necessary to improve the quality of the meals offered in relation to the nutritional aspect, by promoting the adequacy to the soldiers' needs. Other types of quality were not studied, but they are important when evaluating acceptability of meals.
