The aim of this diploma thesis was to evaluate the eating habits of students at a grammar school. We directly monitored students of the first, third, fifth and seventh year of an eight-year grammar school in Trebon during the academic year 2010/2011. The research can be divided into several parts. The first part of this work consists of evaluating the nutritional quality of lunches of selected micronutrients and macronutrients and comparison with the standard requirements for the age brackets. The second part is focused on the diversity of diets in terms of representation of individual foods and meals. These data were compared with the recommended consumption basket. In the third part I monitored eating habits of students by using a questionnaire survey. In the fourth part there is a comparison of BMI values of individual pupils at the beginning and at the end of the school year, including the assignment of percentile. The hypothesis test was evaluated in the fifth part of this thesis. Regarding to the analysis of the various menus was found that annual energy intake from lunch of the students in the first and third year of a grammar school was less than the recommended values. By the contrast this is met by students in the fifth and seventh year of an eight-year grammar school. Annual protein intake from lunch in all classes reached the high value. Fat intake by the students in the first and the third year was in a range of the recommended standards. A slight increase of the macronutrients was found out in meal of students in the fifth and seventh year. The daily recommended intake of carbohydrate was in the average year-round directly lower; about 3,3% the first class, 3,6% the third class and 2,05% the seventh class. Lunch in the fifth year of an eight-year grammar school achieved the desired quantity. The analysis also shows that the intake of dietary fibre was at all four classes of students in sufficient quantities. The intake of calcium in all classes was lower than the recommended standard. The intake of magnesium was higher in all classes than is recommended. Lunch of students in all classes contains a sufficient representation of other minerals. The daily recommended intake of vitamin A in all classes was higher than the given recommended valueThe daily recommended dose of vitamin C was received in the amount of 108% in the first class, 117% in the third, 128,4% in the fifth, 125,6% in the seventh. According to the research vitamin B6 and B12 was received in excess. By comparing the diversity of menus was found that the consumption of yeast soup fails. Pulses soups were represented by the standard. This research also discovered the lack of meat-less/vegetarian meals, chicken and pulses meals. On the other hand fried, sweet meals and pork meat was chosen very often. It should be noted that diversity is influenced by the students themselves, by their choice at all. The survey shows that there is the same amount of students who have breakfast and the same amount of those who don´t. The eating of morning and afternoon snacks is likely rare. Student who took part in this survey also pointed out that they have lunch regularly in the school canteen. Nobody mention his/her distaste to daily consumption of fruit or vegetables. The fluid intake was inadequate in most cases. BMI for most students is in the norm. There is only a minimum of respondents with low weight, overweight or obese. Hypothesis testing has not shown that the missing breakfast causes higher BMI. The level of eating at the eight-year grammar school measured in the studied canteen corresponds to the most evaluated parameters to the nutritional requirements of children's ages. Consumer basket is filled, but the variety of the menu is influenced by the consumers themselves.
