The increasing requirement for energy and nutrients as a child grows older may result in nutritional deficiencies. The research was to assess the intake level of essential amino acids in the daily diet of children and adolescents living in rural areas. The research was conducted using a questionnaire that analysed food products consumed every day. The questionnaires were completed with the help of the researcher over a period of 7 d. Anthropometric measurements were carried out on every research participant. The participants' financial situation was calculated using a 5-degree scale, where 5 meant very good and 1 very bad. Insufficient body mass was recorded in the study group in 11.1% of boys and 14.7% of girls. Excessive body mass occurred more often among the girls (31%) than the boys (27.9%). Among boys aged 7-15 y old, protein provided 12.8% of the calorie requirement, while for the girls the figure was 13.6%. Among pupils aged 16-18 y old, the figures were 14.06% for boys and 14.33% for girls. Analysis of the results showed that irrespective of age or gender, no insufficient intake of amino acids was recorded among the study participants. In the study group of children and adolescents from rural areas, every third study participant suffered from excess body weight. Due to the fact that the intake of essential amino acids exceeded recommended RDA, it is vital that educational programmes are implemented on how to maintain a correctly balanced diet.
