Daten der WHO belegen fast weltweit eine Jodmangelversorgung der Bevölkerung. Auch Deutschland wird zu den Jodmangelgebieten gezählt. Um repräsentative Daten zur Jod-versorgung verschiedener Bevölkerungsgruppen in Deutschland nach der Wieder-ver-einigung zu erheben, wurde ein Jod-Monitoring durchgeführt. Das Jod-Monitoring besteht aus 4 Teilstudien. In dieser Arbeit wird die Teilstudie, in der die Jodversorgung junger Männer, in diesem Fall Wehrpflichtige einer bestimmten Alters-gruppe, untersucht wurde, detailliert dargestellt. Dazu wurde die Jodausscheidung und die Jod-zu-fuhr der Probanden ermittelt. Die Jodaus-scheidung wurde in Spontanurinproben gemes-sen. Die Jodzufuhr wurde nach den Angaben eines Fragebogen berechnet. Ergänzend wurde in den Regionen, in denen das Jod-Monitoring durchgeführt wurde, der Jodgehalt in Trinkwasserproben analysiert. Die statistische Auswertung erfolgte im Hinblick auf regionale Unterschiede (Vergleich Nord/Süd und neue/alte Bundesländer). Die Arbeit enthält eine systematische Analyse der erhobenen großen Datenmenge. Daraus lassen sich Erkenntnisse über das Ernährungsverhalten, den Wissensstand zum Thema Jod und über die regionale Ausprägung der Jodversorgung der Probanden gewinnen. Sie bildet somit eine geeignete Basis für spätere prospektive Erhebungen zur Jodversorgung der Bevölkerung in Deutschland. / Data published by WHO prove a world-wide lack of iodine intake by the population. Even Germany is known as area of nutritional iodine deficiency. An iodine monitoring study has recently been undertaken with the aim of collecting representative data from different sections of the German population following reunification. The iodine monitoring project comprised four partial studies. The present paper represents such a partial study, giving details of iodine intake of young men, in this particular case of persons liable to military service of a specific age group. Iodine excetion and iodine intake of the tested persons were determined. Iodine excretion was measured on the basis of spontaneous urinanalyses. Data on iodine supply were determined in accordance with a questionnaire. In addition, the iodine content of drinking water in the areas covered by the study was determined. Statistical evaluation of the data was performed in respect to regional variations (comparing nothern and southern areas and new/old Lands of the Federal Republic of Germany). The study includes a systematic analysis of the voluminous data set. It allows insights into the eating habits, the status of knowledge about the significance of iodine and on the regional state of iodine supply available for the tested persons. Summing up, this study offers itself as a basis for future prospective studies with respect to the iodine supply of the German population.

6 Abstract Basis: This master's thesis deals with the issue of foods affecting thyroid function. The thyroid gland is an important endocrine organ involved in many bodily processes, it is completely dependent on external iodine intake and at the same time it is susceptible to some naturally occurring antinutritive substances. The main subject of research were therefore the sources of iodine and strumigenic substances in the diet and their occurrence in the diet of adults. The main sources for this thesis include the monograph Thyroid Gland, organized by Zdeňka Límanová, websites of professional institutions of the Ministry of Health of the Czech Republic and the World Health Organization and of course current studies dealing with this issue available in world health databases. The topic was chosen by the author on the basis of finding current topics in the field of nutrition, that have not yet been reserched by other students in the Nutrition Specialist field of study in recent years. Aims: The primary goal of the master's thesis was to examine and process current issues of thyroid function, especially in connection with the consumption of foods that affect this function. For this purpose, a questionnaire was compiled to obtain sufficient base and data to determine the average consumption of iodine and...
