Prachárová, Adriana ; Vysoká, Marie (referee) ; Márová, Ivana (advisor)
This bachelor thesis deals with properties of selected fruits and seeds of superfoods, the introduction of their biologically active substances and comparison of their nutritional properties. The theoretical part focuses on characterizing the fruit itself (pineapple, banana, blueberry, kiwi, raspberry and orange) and seeds (chia seeds, poppy seeds and almonds). It is focused on characterization of bioactive substances contained in them, such as polyphenols, flavonoids, antioxidant activity, vitamin C, vitamin E and fatty acids. Further, used methods are described. In the experimental part, the content of the antioxidant activity and biological effects in selected fruits and seeds was measured and concentrations was calculated per 1 g of dry matter. Finally, a sensory analysis consisting of eighteen fruit and seed combinations is introduced. The aim of the thesis was to find out which of tested combinations are nutritionally high and, simultaneously, acceptable for consumer.

Ginger and broccoli as superfoods
Techlovská, Anežka ; Meisnerová, Eva (advisor) ; Ryšánková, Marie (referee)
The aim of the Bachelor's thesis is to investigate the infamous "superfoods" and to find out how nutrition therapists feel about this group of foods. The thesis is divided into a theoretical and a practical part. The theoretical part is based on scientific articles and studies and examines the characteristics of two specific representatives of "superfoods": ginger and broccoli. Each of these foods is looked at primarily in terms of chemical composition, the content of the most important substances and their potential effects on human health. The practical part is aimed at nutritionists and other food therapists. It took the form of a survey to find out whether professionals are familiar with 'superfoods' and their selected representatives, whether they recommend this group of foods in their practice and what their opinion of it is. The results showed that the vast majority of nutritionists consider ginger and broccoli to be superfoods and recommend both for consumption in their practice, but less than half recommend superfoods in general. A plurality of experts think that ginger is analgetic, antiemetic and antioxidant, while less than half think that it prevents the development of neuro-degenerative diseases, lowers LDL cholesterol and counteracts the development of malignant diseases.

Superfoods and their nutritional evaluation
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...

In the practical part I asked several questions related to the problematics of superfoods and with the use of sent out questionnaires investigated whether people know superfoods, what is their opinion on them, if they buy them and whether they think about their origin and deeper problematics of the import of exotic crops.

Whole 40 percent of people were somewhat sceptical of these foods and only 18,5 percent expressed full trust in them. Almost 73 percent of respondents buy superfoods at least once a week, which reflects their more frequent consumption, while the...

Consumers are aware that flaxseeds are beneficial to health, but they could not list the specific effects. It was further found that consumers do not know the composition of the bread they buy. Based on the data and information gathered, possible solutions that could lead to increased consumption of selected functional foods were proposed.
