Biodostupnost vitamínu C z různých zdrojů
Gabrhelová, Lucie
Vitamin C is classified as a hydrophilic vitamin and performs several functions in the human body. It is necessary to obtain it from food, because people have lost the ability to create it due to evolution. Fruits and vegetables are the most important food sources. It is a relatively unstable vitamin and its losses can occur during food processing. Therefore, there are gentler methods of adjustment by which it is possible to limit the given losses. In order to increase stability and thus bioavailability, other methods are also used, most often different types of encapsulation. In addition to food, vitamin C can also be obtained from dietary supplements. These are available on the market in several forms, which differ not only in price or appearance, but above all in the bioavailability of vitamin C itself. The most effective form is liposomal vitamin C, which is in this form able to ensure high bioavailability of vitamin C.

Women with diagnosed endometriosis, which were part of the observed sample were not even half informed about influence of nutritional factors on this illness. There has not been proven significant statistical dependence between awerness about influence of nutritional...

Nesnidalova, Andrea ; Vágnerová, Tereza (advisor) ; Bárta, Michal (referee)
Seniors often buy inappropriate combinations of dietary supplements based on advertising or peer recommendations, but often to a lesser extent on the recommendation of a professional. It is important for seniors to pay attention to the quality and variety of their diet in order to maintain good health. The bachelor thesis is divided into theoretical and practical parts. In the theoretical part, the first chapter describes the individual vitamins and minerals. The next chapters deal not only with their deficiency and need in the elderly population but also with their correct consumption with regard to further pharmacotherapy. In particular, a chapter dealing with the reasons leading to insufficient food intake in the elderly is described. For the practical part, three main objectives have been set. The research was conducted by questionnaire survey to which a total of 67 respondents aged 65-90 years answered. The first objective was to find out what dietary habits seniors have in their home environment and what vitamins and minerals they are deficient in. A sub-objective of this question was to determine whether current supplementation is justified in this population given the results of the questionnaire survey. The second objective builds on dietary diversity and explores the principles of good...

The issue of vitamin D in elite sport
Káchová, Nikola ; Dostal, Jiří (advisor) ; Kalendová, Barbora (referee)
Vitamin D is a fat-soluble vitamin that can be synthesized in the skin after exposure to sunlight or obtained through food or supplements. The aim of this study was to investigate the effect of 14 days of sun exposure in an area with higher levels of UV radiation (Dubai, United Arab Emirates) on vitamin D concentrations in a selected group of water slalom athletes and to further evaluate the changes in concentrations after a further 14 and 30 days after return. Data for the study were obtained by using four blood draws and comparing the average vitamin D concentration between the blood draws. Eleven elite athletes aged 18-35 years who were not taking vitamin D supplements participated in the study. The results showed that before the intervention, the athletes had average vitamin D levels lower (69.4 nmol/l) than the lower reference limit set at 75 nmol/l. Exposure to sunlight for 14 days resulted in a significant increase in vitamin D concentration, with an average increase of 10.8 nmol/l in the study group. Upon return to the Czech Republic, the vitamin D level increased slightly by an average of 0.7 nmol/l for 14 days, but this increase was not statistically significant compared to the previous sampling. After 30 days of stay, the vitamin D level decreased on average by 1.3 nmol/l. This result...
