Bajaníková, Viera ; Dostálová, Jana (advisor) ; Svačina, Štěpán (referee)
Superfoods have become a huge trend in the fields of wellness and nutrition, but their nutritional value is often overestimated. The information surrounding this type of food is often inaccurate and misleading, however that does not mean that people can not benefit from adding superfoods to their diets - they can provide not only nutritional value, but the sensory one as well. The aim of this bachelor thesis was to examine what the sample of participants thinks of superfoods: whether they are a part of their diet, why, if they perceive any health risks, how much they know about this type of foods and how they asses their price adequacy. The result was that the participants have the knowledge of the the term "superfoods" and they eat superfoods mostly in order to enrich their diet with additional nutrients and because these suit their taste preferences. Most participants do not consider superfoods risky in any way. They are generally not sufficiently educated when it comes to specific superfoods and they find them overpriced, but worth the money (because of perceived health benefits). I have also compared vegetarians/vegans to the other participants and healthcare workers/students of health-related fields to the other participants. Both vegetarians/vegans and healthcare workers/students of...

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...
