This thesis deals with the importance of milk as a natural source of iodine in human nutrition. The thesis provides a data of the consumption of milk and milk products and their contribution to the protection needs iodine for students and employees of the University of South Bohemia in Ceske Budejovice. The experiment includes a total of 60 people (20 men and 40 women). Empirical data wasobtained within the grant project named GAJU 011/2013/Z and NAZV QH 81105. Data of consumption of milk and milk products were obtained through questionnaires. For men, average weekly consumption of milk was 826.5? 835.1 ml (118.1 ml per day) and for women 912.4? 783.9 ml (130.3 ml per day). Average consumption of yogurt for men was 361.0? 401.4 g per week (51.6 g per day), for woman 428.4? 338.8 g per week (61.2 g per day) and average consuption of cheese was for men 263.0? 240.5 g per week (37.6 g per day) and for woman was 260.2? 226.5 per week (37.2 g per day). Through the milk and milk products tested, men average 81.6 g of iodine per day, woman adopted 93.4 g. According to the results, the amout of consumed milk and milk products was lower than the nationwide average, but still covered more than half of daily iodine needs. The thesis presents the data of the iodine concentration in urine for students and employees of the University of South Bohemia in Ceske Budejovice (n=62) as an indicator of iodine supply to the organism. The average iodine content in urine of all subjects (men and women) was 230.4? 171.3 gl-1, for men (n=21) reached 244.6? 195.2 gl-1, for women was 223.2? 159.8 gl-1. Results of the average iodine content in urine reflected the physiological range, i.e. for the students and employees of the University of South Bohemia was supply of iodine in organism sufficient. The thesis also provides information about the amount of iodine in asamples of cow´s milk on a selected farm (n=50) of the Jihocesky region, the Plzensky region and Vysocina during the years 2011 - 2013. Samples of cow´s milk were obtained in collaboration with the Central Laboratory of dairy Madeta a.s in Ceske Budejovice and Veterinary Centre s.r.o Susice. In 2011, the average concentration of iodine was 321,0? 337.8 gl-1, in 2012 was concentration of iodine 298.8? 290.8 gl-1 and in 2013 was 234.7? 116.1 gl-1 also otherwise: in all years was it was determined that there was an abundance of iodine. The highest values (315.6? 305.1 gl-1) of iodine was in the Jihocesky region. In Vysocina a lower average level of the iodine was detected (9.5 %), as well as in the Plzensky region where the amount of iodine in milk was lower by 53.7 %, compared to the South Bohemia region and 48.8 % compared to the Vysocina region.
