Vokounová, Kateřina ; Zikán, Vít (advisor) ; Michalská, Dana (referee)
Introduction: Osteoporosis is a chronical systemic metabolic disease of bone tissue, which is manifested by a decrease in the amount of bone mass and/or a decrease in its quality and may result in a fracture. Fractures are also common for primary hyperparathyroidism due to increased parathyroid hormone secretion. Surgical treatment will help increase bone density in most cases, nevertheless emphasis is placed on reducing risk factors for osteoporosis and fractures. Objective: Purpose of this thesis is to map the nutrition condition with focus on calcium and protein intake of postmenopausal women after successful surgical intervention for primary hyperparathyroidism (PHPT group), and to evaluate the results in relation with osteoporosis and fractures. Methods: Nutritional status was assessed using questionnaires of eating habits and analysis of three-day menus. Intakes of energy, protein, fat, sugar, fiber, free sugar, vitamin C, sodium, calcium nad phosphorus intake were calculated using Nutriservis PROFI program (and other nutritional databases). The degree of vitamin D saturation was obtained from serum calcidiol concentrations. Body composition and bone mineral density parametres were measured using dual energy X-ray absorptiometry. Results: Nutritional analysis of diets showed no statically...

Health importance of phytochemicals in berries focused on weight-reducing diet
VOKOUNOVÁ, Kateřina
Bachelor´s thesis named "Health importance of phytochemicals in berries focused on weight-reducing diet" deals with the weight-reducing diet containing phytochemicals and its health effect on human heatlh. In theoretical part of the thesis, I focused on weight-reducing diet and bioactive substances, and I described phytochemicals and blueberries in detail. The formation of a two-week weight-reducing diet containing polyphenols correspondig with the amount of 120 ml natural blueberries a day was the goal of my thesis. The exploration of food products as fully-fledged sources of polyphenols was my next goal. For the processing of the research I have examined food products containing blueberries, which were made in the South Bohemian region, specifically through interviews with leaders and representatives of various companies and I found all the necessary information about each food products containing blueberries. The amount of polyphenols was determined by HPLC (High Performance Liquid Chromatography) which was conducted under the leadership of doc. MUDr. Petr Petr, Ph.D. I finished counting the amount of polyphenols in some food products from the initial analysis. I have included these products in the weight-reducing diet with any possible adjustments to meet the criteria of weight-reducing diet. I included natural blueberries in many meals in various modifications. The richest sources of natural polyphenols were frozen blueberries and beverages containing natual blueberries. There were natural blueberries refrigerated or frozen, Herbal tea with blueberries or dairy products containing blueberries the most appropriate for the weigt-reducing diet.
