Knowledge of principles of healthy nutrition at pupils 13 - 16 years old

The bachelor thesis Knowledge of principles of healthy nutrition at pupils 13 - 16 years old consists of a practical part and a theoretical part. The theoretical part is focused on basic information on a rational nutrition and on basic nutrients needed for the organism development. It informs on the nutrition in the period of pubescence and on subsequent mistakes made by teenagers. It draws attention to the necessity of regular meals in the course of the day, which is in this period of life very important and which should not be underestimated. Instructions for a proper healthy diet can be prepared with the help of so called food pyramid. The practical part presents achieved results. I applied a quantitative method of the research in the bachelor thesis. The data collection was made by means of a questionnaire, which was given to the pupils at the age between 13 and 16. The research was made at the secondary schools in the Bohemian-Moravian Highlands. Five secondary schools were addressed. Totally, 229 questionnaires were distributed, 21 of them could not be used because of incorrect or insufficient completing of the data. The return was therefore 90,8 %. 208 questionnaires were used for the research, thereof 100 questionnaires were completed by girls and 108 by boys. The aim of the bachelor thesis was to determine the knowledge of principles of healthy nutrition at pupils 13 - 16 years old. Another objective besides charting the alimentation problem was also to confirm or refute three hypotheses. Hypothesis H1 supposed that pupils in the age between 13 and 16 years have a satisfactory knowledge of healthy nutrition. This hypothesis was confirmed. Hypothesis H2 supposed that most pupils follow the principles of healthy nutrition. The results did not confirm the hypothesis. Hypothesis H3 supposed that pupils have a possibility to eat according to principles of healthy nutrition, but most of them are satisfied with the current diet and would not change anything. The bachelor thesis can serve as a source of information on the healthy nutrition and correct eating of teenagers. It can be used by parents who have a possibility to influence the home menu significantly. Furthermore, teachers can warn pupils of the mistakes in the nutrition and so that they can lead them to a healthier diet
