Students' Awareness about the Nutritional Value of Fats
Hlaváčková, Zuzana ; Marádová, Eva (advisor) ; Vodáková, Jitka (referee)
Bachelor theses is concerned with the fats in terms of nutrition, where fats are regarded as one of the basic nutrients in human nutrition. Specifically, is concerned with the characteristics of fats, chemical composition, technological processing and the importance of diet in humans. The first objective of this theses was to create a literary overview of the fats in the diet. The second objective of this theses was to clarify the extent to which selected high school students an overview of fats and chat they have the knowledge, which in turn can use in your everyday life when choosing foods and preparing meals. For this purpose was performed a questionnaire survey among selected students of secondary education and its results are discussed in the conclusion of this theses. Keywords Fats, nutrition, margarine, fatty acids, knowledge, education

Importance of nutrition, mainly proteins, in power sports.
Šesták, David ; Bláha, Pavel (advisor) ; Martinča, Jozef (referee)
Heavy athletics is a great stress for a human organism. This stress has to be compensated by proper nourishment and proper relaxation. Higher intake of all nutrients is always linked to heavy athletics. Some nutrients, such as omega-3 fatty acids, iron, zinc and proteins have a unique role in strength disciplines. Especially proteins are considered by both amateur and professional athletes as the most essential for muscle building. It is questionable how much protein is needed and how does its quality (directly linked to digestibility and absorbency) differ in animal and plant proteins, or even in supplementations proteins. The types of nourishment proteins that are combined together and what type of training is preferred matter significantly. Other agents of high significance are evidently, with direct or indirect influence, carbohydrates, dietary fiber, fats, vitamins, minerals and drinking habits.

Comparison of nutritional values of different edible insect species
Maňhal, Daniel ; Kouřimská, Lenka (advisor) ; Kulma, Martin (referee)
The worlds limited agricultural resources will soon no longer be able to continue to support its ever growing population. One way to alleviate this problem is to integrate insects into the human diet, which is an increasingly common practice in Asia, Africa and South America. This practice has proven to be beneficial in a number of ways. Insects have better feed-conversion efficiency, transforming organic matter into larger amount of edible body mass than traditional livestock. Comparing to the livestock, insects have much smaller ecological impact on the environment. On the other hand, allergic reactions to toxins produced by some insects represent a potential risk of entomophagy. Nutritional values of insects depend on many factors, such as type of insect, its developmental stage, sex, and consumed feed. Generally, insects are a rich source of nutrients comparable to or even higher than traditional sources of meat.
Nutritional values of farm raised field crickets (Gryllus assimilis), originating from the Czech Republic, were analyzed in the experimental section of this thesis. Specifically, contents of dry matter, crude protein, fat and fatty acid profile were the main focus. The dry matter content was determined using an infrared technique. The crude protein content was measured using the Kjeldahl method. The Soxhlet method was applied for fat extraction. Extracted fat was determined gravimetric. Using gas chromatography, a lipid profile was obtained. Measured values were compared to those found in the literature. Emphasis was put on the comparison with other types of potentially edible insects and on the nutritional values of wild and farmed insects. Finally, these nutritional values were compared to the corresponding nutritional values of conventional meat to illustrate the benefits of entomophagy.
The analyzes showed that insect originating from the Czech Republic had very similar qualitative composition to species from different geographical regions and its nutritional value is fully competitive with conventional meat.

System for the collection of oils and fats from population
Lebeda, Tomáš ; Altmann, Vlastimil (advisor) ; Mimra, Miroslav (referee)
The aim is to assess whether it would be appropriate and possible to extend the separate collection of waste by collecting used edible oil from households. The aim is to demonstrate that the intention is not too costly initial investment and does not require permanent financial subsidy. It is designed recovered system with regard to the lowest possible cost. The main tasks was to identify potential recovered population, determine the recovered system with regard to legislative procedures to determine appropriate waste collection containers and pick-up technique and the assessment of the project in terms of economy. In the Literary sources are given the mechanisms used for logistics of waste management. In your own work experience has been established and the existing system is extended and elaborated on the specific properties of oils. The project is completed economic evaluation with regard to population density collection sites and recommendations are made for practice. Finally, it is a discussion of the proposed system and has been operated by way of collection in some areas.

Nutrition of top bodybuilders
Knobová, Kateřina ; Hučko, Boris (advisor) ; Kodeš, Alois (referee)
This bachelor thesis outlines nutritional guidelines for top bodybuilders, including the bulk phase, drawing preparation and recovery period.
Bodybuilding consists of a number of mutually related and interdependent parts (training, recovery, nutrition, lifestyle, dietary regimen etc.) and neglecting one single of them may have a significant impact on final achievements.
Nutrition is one of the principal issues in bodybuilding.
The thesis describes the key nutritional attributes for the first year of the recommended diet, starting with the basic nutrients (proteins, carbohydrates and fats), supplementary components such as vitamins, minerals and dietary supplements, and including a list of recommended foods.
The thesis shows that top bodybuilders´ diet is very specific, although, interestingly enough, consisting largely of regular food items that are suitable for any humans. The most important attributes of the diet are quality and content of nutrients, as well as their amount and rate of absorption. The timing of the diet intake, drinking schedule, the use of selected supplements are also relevant. The thesis provides an overview of key supplements like vitamins and minerals, protein and carbohydrate concentrates, anabolic boosters and NO supplements, joint nutrition, BCAA (Branched Chain Amino Acids), fat burners, arginine, creatine, glutamine etc.
One of the unique attributes of bodybuilders' lifestyle and diet can be seen in alternating between phases of intensive training and regeneration, which is driven by their sheer will and dedication.

Vliv výživy matky na vývoj plodu
Vašková, Petra
This thesis deals with the importance of the diet of pregnant women during pregnancy on the developing fetus. Sufficient and proper nutrition before and during pregnancy is important to allow fetal growth, to mental and intellectual development of the full potential. Nutrition affects fetal health during childhood and adulthood, with possible impact on the next generation. It is emphasized the importance of essential nutrients, macroelements and microelements, which are important in pregnancy, along with diet recommendations. Unbalanced, inadequate or, conversely, excessive intake of individual food components, or consumption of risk aliment may lead, for example, to congenital malformations, low birth weight, in serious cases even to abortion. The main goal of this thesis is to describe the importance of the individual components of the diet in pregnancy, give current scientific information on the effects of maternal nutrition on fetal development, assess the risks, arising from the lack or excess of certain ingredients and propose a recommended daily dose of nutrients.

Dietary supplements with adaptogenic effects
Izraelová, Alexandra ; Vespalcová, Milena (referee) ; Souralová Popelková, Miriam (advisor)
The aim of this thesis was to design a recipe for the dietary supplements with adaptogenic effects, production, and subsequent analysis (proteins, lipids, carbohydrates), which led to the determination of the energetic value of preparation. Adaptogenic effects are the domain of plants and fungi, known as adaptogens. Adaptogens act non-specifically to the human body - improve the overall condition of the body, accelerate healing and regenerative processes, slow degenerative processes in the body and thus the aging process. As biogenic active stimulators, they affect not only in the physical but also in mental area. Dietary supplements have been designed in three different forms - capsules, syrup, drops. The analysis was also performed in tablets of Vietnamese origin supplied by supervizor, of which entry to our market is being considered. Protein content was determined by Kjeldahl method, lipids by Soxhlet extraction, saccharides by gravimetric method. Dietary supplements were analyzed for heavy metals (Pb, Cd, Hg), and in herbal drops ethanol content was determined.

Evaluation of selected dietary supplements - climacterium
Tobolková, Blanka ; Vránová, Dana (referee) ; Zemanová, Jana (advisor)
A dietary supplement is a product that contains nutrients (e.g. vitamins, minerals, herbs, amino acids or fatty acids) intended to supplement the diet. The aim of the diploma thesis was to suggest a prescription for preparation of three types of dietary supplements which are used to reduce of climacteric symptoms, their production and determination of energetic (nutrition) value on account of detected content of proteins, fats and saccharides in dietary supplements. A part of the diploma thesis was to suggest suitable wrapping and price of prepared dietary supplements. The three dietary supplements were used for analyses, namely capsules, herb syrup and herb drops. The content of proteins was determined by Kjeldahl´s method, total fats were determined by Soxhlet extraction and saccharides were determined by titration with potassium permanganate (Bertrand´s method). Dietary supplements in form of capsules were particular analysed on content of heavy metals (lead, cadmium and arsenal). In herbal drops was in addition determined alcohol content (ethanol). There was from the measured data found out, dietary supplement in form of capsules was chosen as the product with the lowest energetic (nutrition) value.
