Healthy diet is one of the most important factors determining somatic and mental development of children. The reported study aimed to assess food intake and nutritional status of 600 children aged 11-14, pupils of primary schools in the city of Poznań. The 24-h recall was taken to evaluate the total intake of basic nutrients, i.e. proteins, fats and carbohydrates. The nutritional status of children was evaluated based on the measurements of basic anthropometric parameters, i.e. body weight and height, and body mass index (BMI). It has been found out that the daily food rations did not cover the daily demand for basic nutrients according to the recommended norms. Daily food rations (DFR) oversupplied calories (112-125% of the recommended norms) and fats (120-130%), with concomitant insufficient supply of proteins (95% of the recommended intake). Cholesterol and saccharose intakes were higher from recommendations and amounted to 124-150% and 174-194%, respectively (Table 1). Even more pronounced insufficient protein intake was reported in older children. The analysis of basic anthropometric parameters has, however, confirmed adequate physical development of most of the children from the studied population, i.e. 70-80% (Tables 4 and 5). Nevertheless, prolonged dietary deficiencies may predispose to various developmental abnormalities and diet-dependent disorders.
