This bachelor thesis focuses on the intake of the added sugars among the population of young adults, particularly among the adults in the group of 30 to 45 years of age. The theoretical part of this thesis provides a brief overview of the saccharides based on their chemical composition and elementary classification. The sugars and the natural as well as the synthetic sweeteners and their use in the food industry are then discussed in detail. The concepts of naturally occurring and added sugars are described including the related legislative requirements for food labeling and nutritional recommendations issued by the international and national institutions. The special attention is devoted to the role of sugars in nutrition and to the health risks arising from an excessive sugar intake. The research part of the thesis includes a survey carried out in the form of a questionnaire aiming to investigate, in particular, the consumption of the sweetened soft beverages, the fruit products and the breakfast cereals and to defend the hypothesis that the chosen group of the population consumes the added sugars in an excessive amount. The practical part embodies also an analysis of the weekly diet of eight persons of the given age category focused on the amount of the total sugar intake. Although the excessive...

The nutritional importance of legumes in human diet
Chalánková, Veronika ; Bušová, Milena (advisor) ; Dostálová, Jana (referee)
This Bachelor's thesis is focused on the nutritional importance of different kinds of legumes, their favorable and unfavorable nutritional properties and their effects on the human organism. Legumes (or pulses) are a very valuable food because of the content of many nutritionally important substances and are clearly a part of healthy diet. They are the most important plant source of protein and fiber and are classified as foods with a low glycemic index. Consumption of legumes is not too high among ordinary population. Doubts about legumes can be caused by the content of so-called antinutrients, which, for example, reduce the use of nutrients and may cause digestive problems. However, these substances can be eliminated by appropriate treatment. In addition, they are biologically active substances that also exhibit positive effects on human health, especially antioxidant and anti-carcinogenic, and thus can play a role in the prevention of both tumor and metabolic diseases. Nowadays they are still the subject of research. The practical part of this thesis includes a field survey of the offer of legumes and products with their contents in stores. The range of these products is very rich nowadays and greatly simplifies including legumes into diet. However, the consumers must be careful about the...

Development of problems of area planning from the point of view public health protection authority
Dostalová, Jana ; Švarcová, Jaroslava (advisor) ; Rödlová, Sylva (referee)
In my thesis I have decided to perform an analysis of issues relevant to the development of zoning and territorial planning from the perspective of a public health protection authority. I think it is important to point out that the legally established approach used to define "supervision" was different in 2000, when the relevant legislation applicable to health protection regulated specific areas of supervision than Act No. 258/2000 Coll., which is currently in force and which determines health risk evaluation process. A part of my work explains the relationship between the evaluation of impacts on sustainable development of the relevant area, the assessment of environmental impacts and assessment of impacts on public health, which are principles that need to be taken into consideration when performing zoning and territorial planning. The current legislative amendment enforced by the Building Act together with the health risk assessment principle (and related evaluation of impacts on public health), provides consistent protection of public interests during zoning and territorial planning. These are activities and measures necessary for the creation and protection of healthy living conditions. The approach of public health authorities towards the implementation of opinions and ideas in terms of...

The trans-fatty acids in subcutaneous fat and in fat content of breast milk as an indicator of their nutritional intake
Dlouhý, Pavel ; Anděl, Michal (advisor) ; Dostálová, Jana (referee) ; Hrubý, Stanislav (referee) ; Zadák, Zdeněk (referee)
Trans fatty acids (TFA) are unsaturated fatty acids, which have one or more double bonds in the trans configuration. Their main dietary sources are partially hardened fats and food products containing partially hardened fats (margarines, shortenings, bakery products, and fast foods). TFA are thought to increase the risk of coronary heart disease and type 2 diabetes. These fatty acids have adverse effects on blood lipid levels, increasing LDL-cholesterol while decreasing HDL-cholesterol. Consumption of TFA can also impair insulin sensitivity. High intake of TFA is associated with systemic inflammation, activation of immune functions and endothelial dysfunction. Hypotheses also exist that TFA may have adverse effect on the metabolism of essential fatty acids and foetus development. The concentration of TFAs in subcutaneous fat is a very good indicator of dietary exposure of TFA. This concentration reflects long-term dietary intake of these fatty acids. Levels of TFA in human milk are more variable; however, it is quite simple to obtain a sample of human milk. The purpose of our studies was to determine (a) content of TFA in subcutaneous fat samples from persons with coronary atherosclerosis and from persons with no sign of coronary dinase and (b) the content of TFA in early human milk of breast-feeding women...
