Meaning and resource of selenium in human nutrition
KRATOCHVÍLOVÁ, Zuzana
Bachelor's thesis concentrates on functions of selenium in human nutrition. Selenium is an essential trace element of importance to human health. Its availability depends on the concentration of selenium in the soil. The average income of selenium in the Czech population are usually 36 g/day per individuals. Excess or insufficient selenium intakes can result in adverse effects on human health. The most important sources of selenium in the diets of most people are meat, fish, eggs, milk, cereals and nuts. Selenium plays an important role in a number of metabolic functions including antioxidant systems, thyroid hormone metabolism, immune function and reproduction. Low selenium status are associated with increased risk of mortality, poor immune function, and cognitive decline, while high selenium status cause garlic breath, hair and nail loss, disorders of the nervous system and skink and poor dental health. Amount of selenium and its need changes during life. Recommended doses of selenium for women are 55 g/day and for men 70 g/day. Pregnant and lactating women require an average of 65-75 g selenium/day. Selenium deficiency in women causes problems with pregnancy, fetal malformations or postnatal complications. Newborn baby receives in breast milk about 10 g selenium/day. The recommended doses for children are in the range of 20-30 g selenium/day. The lack of selenium in seniors causes loss of muscle mass and strenght. Conversely sufficient doses of selenium can prevent the development of osteoporosis and various health complications. During sport aktivity, in the body there arise a large amount of free radicals and that is why it is necessary to suply the body of a sufficient amount of selenim, which helps prevent with its antioxidant effect oxidative damage of the muscles. The population exposed to low levels of selenium, the lack can be increased by use of dietary supplements with selenium.

Chemical hazards of contamination of foodstuffs and dishes
MARŠÁLKOVÁ, Alena
The bachelor thesis deals with the risks of chemical contamination of food and possible health risks for the consumers. Firstly, there is a general outline of foreign substances including the additives, which are added to foods intentionally, and contaminants. The contaminants are viewed as undesirable substances which occasionally occur in foods. They develop directly in the foods or penetrate into them from the outside during the basic stages of agricultural production, in stores, during transportation or during processing for culinary purposes, or due to environmental pollution. Such substances can have negative effects on human health. The second part of the thesis focuses on concrete contaminants - nitrates, nitrites and acrylamide. Nitrates and nitrites are both contaminants and additives. Their use as food additives is motivated by their sensoric and protective effects. The sensoric function is to ensure a permanent pink colour of smoked meat and other meat products. The protective function consists in inhibiting the growth of the microorganisms Clostridium botulinum and thus preventing the origination of dangerous botulin. The nitrates exist as contaminants mainly in foods of vegetable origin, penetrating them from soil and water due to nitrogen cycle in the nature. The acrylamide is a newly discovered food contaminant. It is considered to be a very dangerous substance as regards possible peroral exposure. The danger consists in its neurotoxic, genotoxic and possible carcinogenic effects. It originates in foods with a higher content of reducing sugars during the process of production or culinary processing if the temperature is higher than 120° C. The thesis should provide information for the public as consumers or providers of different food-processing facilities. Its main objective is to pinpoint some risks connected with the consumption of various foods and meals, and to eliminate the risks as much as possible or to avoid them completely.
