Dietary supplements and iodine supplementation for children 11-12 years in the Czech Republic
HALÁSZOVÁ, Monika
Bachelor Thesis called "Dietary supplements and iodine supplementation for children 11-12 years in the Czech Republic" deal with the intake of dietary supplements containing iodine and intake of other significant dietary sources of iodine in relationship to saturation with iodine in the monitored group of 300 children aged 11-12 years . The thesis is divided into theoretical and practical part. Theoretical part deal with established issues in light of current situation and uses the knowledge of specialized literature in these areas: iodine and his dietary sources, influence of deficient or excessive intake of iodine on thyroid gland and its function, and also the solution to iodine deficit in Czech Republic. The thesis also deals with dietary supplements and nutrition of school-aged children. Practical part is focused on quantitative research. This research was done on selected group of children who had low level of ioduria (iodine in urine) according to State health institution. Statistical file included 300 children of both gender in age from 11 to 12 who live in Czech Republic. The reason why children of this age were chosen is because of importance of optimal intake of iodine in period of physical and sexual evolution. The children were divided into two groups. One group had ioduria up to 300ug/l and the second group had ioduria over 300u/l. Data were collected through questionnaire. Because of age of respondents, the questionnaire was filled in presence of at least parent. The questionnaire should have also served to parents as information about iodine importance for their children. The individual evaluation of ioduria and questionnaire was given to parents upon their request. Collected data were evaluated in Microsoft Excel. In practical part, two main goals and two research questions are set. Their task is to determine the rate of usage of dietary supplements with iodine and to find out what significant sources of iodine the children with ioduria over 300u/l take in. The milk and milk products, salt with iodine, salted delicacies, sea products and dietary supplements with iodine were observed as probable main sources of iodine intake. The first goal was to find out the amount of iodine intake from dietary supplements for previously mentioned group of children. The second goal was to find out if the dietary supplements with iodine (or any other combination of food rich on iodine) are used by observed individuals with ioduria over 300u/l. The results of research show if the respondent's level of ioduria is affected by in taking the dietary supplements or food with significantly higher content of iodine. My own research proved relatively frequent (but irregular) intake of dietary supplements with iodine by whole examined population. On the other hand, usage of dietary supplements with iodine is probably not correlated with usage of table salt without iodine or with thyroid gland illness by individual respondent or in his family. The milk and milk products and table salt with iodine proved to be the main source of iodine. According to research, children with excessive ioduria consume sources of iodine as frequent as other children. Deeper insight into results shows that reason for excessive saturation with iodine is combination of intake of dietary supplements as well as other significant food sources of iodine, especially milk and its products. By several respondents, the higher level of ioduria can be caused by higher consummation of sea products or by usage of dietary supplements with iodine in last two days. The need for better awareness about suitable rate of iodine dietary supplements intake as well as medical importance for lowering the amount of (iodine) table salt in food was discovered by research. The optimal supply of iodine by higher percent of observed population could be also achieved by optimizing the content of iodine in milk.

Vavrečka, Jan ; Švarc, Zbyněk (advisor) ; Boháček, Martin (referee) ; Jakl, Ladislav (referee)
The thesis is focused on theoretical principles of demarcation of products with health effects in the EU law and on the reflection of these issues in the application and administrative practice in commercial law. The thesis developed yet been brought judicial interpretation with the scientific interpretation of certain key and decisive problems that separate from each other law-regimes of regulation: medicinal product for human use, foods, cosmetics products, medical devices and biocides. Correct law-regime for a particular product is determinating of the general legal basis in the EU internal market. It is therefore a important problem not only in EU law, but also in EU economic. Thesis results are highly critical of current practice in the local markets of EU member states, especially Czech Republic, and in many instances documented sub-optimal application of this law in general practice.

Sources and methods of saturation of the organism with antioxidants
NOVOTNÁ, Nikola
The aim of the thesis is to characterize sources of antioxidants and inquire the depth of knowledge about antioxidants among students of secondary school. The theoretical part of the thesis describes and divides important antioxidants for human health. The main sources of antioxidants in human diet are there divided, described and compared as well. The practical part of the thesis includes the inquiry which evaluates the theoretical interest in antioxidants and dietary intake of antioxidant supplements among 17-19 years-old secondary school students. The results are analyzed and graphically displayed. Research shows that more than a half of the respondents know the term antioxidants and consume these substances in the diet. However, it is important to increase knowledge of antioxidants already among young people and ensure the intake of these essential substances from a varied diet.
