The aim of the research was to determine level and sources of dietary fiber (DF) in daily nutrition intake among teenage girls (16–18 age) from Szczecin. According to recommended level of DF, determined average level was much lower and comprised of 45.6% of daily requirements. Source and amount of DF in composite ration were as follows: cereal products 38% and vegetables with fruits 38%. Moreover, content of energy, proteins, carbohydrate, fat and cholesterol were additionally determined in order to compare with dietary guidelines. All stated above elements were present in insufficient quantity and did not correspond to current nutritional guidelines (mean percentage ranged form 54.2 to 80.4%).
