Avaliação nutricional de dietas de trabalhadores em relação a proteínas, lipídeos, carboidratos, fibras alimentares e vitaminas
The analysis of food consumed by a large part of the population is important to establish the nutritional composition of diets to verify if diets are adequate regarding essential nutrients. In the present study, diet analysis results of steel industry workers´ dietary consumption are presented. Workers from 19 to 56 years old were selected and their diets were collected by a duplicate portion technique, including all the meals and beverages consumed over 3 consecutive days. The content of lipids, proteins, carbohydrates, ash, humidity, fiber, vitamins B1 and B2 and piridoxine were determined in 24 diet samples. Comparing the results with the values set by the new dietary recommendation dietary intakes (DRIs), it was observed that the workers´ diets were 100% adequate in carbohydrates and 96% in proteins and lipids. However, dietetic fiber content of the diets was considered inadequate (only 4.2% of adequacy). All the diets were adequate in B1 and B2 vitamins, while 58% of the diets were inadequate in terms of piridoxine.
