Risks of vegan diet
Knotek, Filip ; Chrpová, Diana (advisor) ; Pánek, Jan (referee)
Veganism, in the last few years more and more popular way of eating, is sometimes presented by non-academic articles as "the best" and without risks. However, compete omission of all animal products doesn't have to be as safe as it seems at first sight. The aim of this thesis is to find out what is the knowledge of vegans about the risks of fully vegan diet and also what are their eating habits to eliminate those risks. The theoretical part is mostly focused on risks related to deficiency of essential nutrients. The practical part was focused on research, that was made by anonymous quantitative survey method. The questionnaire was composed of sixteen questions oriented mostly towards knowledge of risks of vegan diet as well as towards eating habits of respondents. A total of 187 respondents met the criteria necessary to be included in the research. The results showed that 80,7 % of vegans know that there are some risks connected to vegan diet. Those respondents had quite good knowledge about the risks summarised in theoretical part of this thesis. Mostly they underestimated the risks of deficiency of omega 3 fatty acids, vitamin D and generally the risk of mineral's deficiency. The eating habits of most respondents often reflected their knowledge about the deficiencies in vegan diet - on average...

Alternative nutrition - use and knowledge of PF JU students
DUNDOVÁ, Jana
The bachelor thesis deals with alternative nutrition and examines the knowledge and its use among students of the Faculty of Education of the University of South Bohemia. The theoretical part deals with basic information about alternative nutrition and discusses possible reasons leading to dietary change. It also describes in more detail the different alternative ways of eating. The most well-known dietary trends among students are vegetarianism and veganism, for which the pitfalls and possible deficiencies in the diet are discussed in detail. The practical part elaborates the students' knowledge and opinion on alternative diets, the relationship to healthy eating and the use of dietary supplements. In addition, it evaluates the representation of different alternative diets, the reasons leading to dietary changes, the perceived changes, or the ways for obtaining nutritional information. The results are based on a questionnaire survey with a total of 101 respondents. Of the total number of respondents, 10% of the students were vegetarian. Other alternative forms of nutrition are less represented. The Mediterranean diet fared best in terms of health benefits in the evaluation of alternative forms of nutrition. However, none of the students surveyed follow its recommendations.

Veganism and its possible impact on organism
MAZÁNKOVÁ, Andrea
This thesis is called Veganism and its Possible Impact on the Organism. People who opt for a vegan diet should have extensive knowledge of this diet, as ignorace could bring many health risks. In the theoretical part of my work, I deal with the concept of veganism, what a vegan diet entails, possible reasons for choosing this type of diet, and the characteristics of the food vegans consume. I then focus in more detail on nutrients that do not occur in the vegan diet, or they occur in significantly smaller amounts, and also where to find them in the diet. I deal with their recommended daily intake and describe the consequences of a deficiency of some of the nutrients. In the practical part of the thesis I set two goals, the first of which was to map the respondents' knowledge of potentially hazardous nutrients in the vegan diet, and the second goal was to evaluate whether the vegan diets of selected respondents meet their energy and nutritional needs. To complete the first goal, I used my questionnaire, which was filled out by 73 people over the age of 15 following a vegan diet. To meet the second goal, I randomly selected eight respondents from the questionnaire who recorded their diet for seven days for my research. Subsequently, I processed their daily menus in the Nutriservis Profi program and compared the resulting values of energy and macronutrients with their recommended daily intake. According to the results, respondents have certain knowledge of the vegan diet, but within the individual questions there are also some wrong answers. On average, the energy intake of selected respondents was lower than their recommendations. Furthermore, the composition of the diet did not match the daily recommendations, average protein values were higher in contrast to fast and carbohydrates, which were significantly lower.

Vegan nutrition and awareness of nutritional defenciencies and their compensation
LÁCHOVÁ, Aneta
In my bachelor's thesis on the topic of Vegan nutrition and awareness of possible nutritonal deficiencies and their compensation, I investigated whether vegans have sufficient knowledge about this diet to avoid possible nutritional deficiencies, which can bring with a number of health complications. In the theoretical part I characterize the concept of veganism and what can be the reasons for choosing a vegan diet. I also focus on more details on the vegan diet, especially on nutrients, which can an increased risk of insufficient intake on the vegan diet. I deal with their recommended daily intake and I also introduce in which plant food this nutrients can be found or if their intake must be supplied by using dietary supplements. For the practical part of my thesis, I set two objectives. The first objective was to map if respondents have the necessary information about a possible deficit of nutrients and if they know how to supplement it. The second objective was to find out if the vegan diet of each respondent is really corresponding to their energy needs. My research group was composed of 5 respondents, three women and two men. I obtained data from them through a semi-structured interview and from their dietary records. The results showed that respondents don't have all information about the vegan diet, which is important for providing all the nutrients and preventing health complications. The dietary analysis shows that the energy intake of each respondent is lower than recommended energy intake. Also the macronutrient ratio didn't completely match to the daily recommendation that was set.

Parents of vegan children and adolescents awareness about the main principles and risks of vegan diet
Šenkýřová, Hana ; Selingerová, Eliška (advisor) ; Heniková, Marina (referee)
Veganism is a way of life based on the effort to eliminate or reduce as much as possible any form of exploitation and abuse perpetrated on animals for human needs. From a dietary point of view, we use the term veganism to exclude all foods of animal origin from the diet. Plant-based diets bring indisputable health benefits, but there may also be certain risks that need to be avoided. In recent years, interest in this lifestyle has increased and we are increasingly encountering it among children, even the youngest, who are particularly prone to health problems resulting from dietary errors. This work is divided into theoretical and practical parts. The theoretical part contains information about the diet during pregnancy and lactation, in childhood and adolescence. Furthermore, attention is paid to veganism, especially from a nutritional point of view. The possible risks of plant diets in children and the recommendations and attitudes of health organizations are presented. The main goal of the practical part of the work was to map what awareness of the mentioned risks and recommendations parents of vegan-eating children and adolescents have and whether they also follow the recommendations in practice. I was also interested in whether and how communication on this topic between parents and...

Transfer of Vegetarian Value Model from Parents onto Their Childern
Vastlová, Markéta ; Cirklová, Jitka (advisor) ; Janas, Martin (referee)
This bachelor's thesis is, as the itself name indicates, concerned with the concept of education of children by their parents - vegetarians, possibly vegans. What is examined is whether they are trying to transfer their own model of values - vegetarianism or veganism onto the child, but also what aspects will influence their future value orientation the most during the course of their primary socialisation. The influence of the informing parent's partner as well as that of grandparents on both sides is considered, further on the influence of the educational institution the child attends is factored in. It is there where the child is confronted with different norms and values than those that the child can be familiar with from the home and parents are then have to resolve the arisen situation. The thesis itself is divided into three main sections which are the following: Theoretical Introduction, Methodology and Research.The first section is dedicated to the theoretical background enabling the confimation of data necessary for the analysis itself. Specifically it outlines the value basis of vegetarianism, explains the difference between vegetarianism and its more radical form veganism. It delineates the influence of family and educational institutions on the latter value orientation of the child....
