Mapping the influence of the Mediterranean (kosher diet) and traditional Czech diet on the incidence of colorectal cancer
Ben-Perets, Diana Ester ; Sládková, Petra (advisor) ; Svěcená, Kateřina (referee)
This diploma thesis deals with mapping the influence of the Mediterranean (kosher) diet and the traditional Czech diet on the occurrence of colorectal cancer. The aim of the study was to identify differences between the eating habits of Israelis and Czechs and to assess their potential impact on the development of this type of cancer. The methodology included an analysis of the eating habits of both groups, epidemiological data and a literature review of relevant studies. The results of the study indicate that there are differences between the eating habits of Israelis and Czechs, with the Israeli diet, although influenced by westernization, showing positive tendencies compared to the traditional Czech diet. This observed difference may play a key role in the prevention of colorectal cancer. Despite the fact that Israelis are not strictly limited to the Mediterranean diet, the study highlights its positive effect on reducing the risk of this disease. On the contrary, the negative contribution of the traditional Czech diet underlines the need to improve eating habits in the Czech population. This work contributes to the literature regarding the influence of diet on health and offers a comprehensive view of the differences between the Mediterranean and Czech diets in relation to colorectal cancer....

Vliv změny stravovacího režimu na vybrané ukazatele mikrobiomu lidského trávicího traktu
Patloka, Ondřej
The literature review of this thesis discusses the intestinal microbiome of the human gastrointestinal tract. The main attention is paid to the chapters on the development of the intestinal microflora within the life stages of a person, the importance of the microbiota in terms of metabolism and influencing the health of the host, and the influence of the way of eating in terms of the intake of basic nutrients and specific food components of the diet, which can change the bacterial diversity and composition of the intestinal microflora. In the practical part, a microbiological analysis of the fecal microflora of six individuals (n=6) who underwent a weight reduction course was performed. During the experiment, 3 microbiological analyzes of the stool of the probands were performed within the monitored period, i.e. (at the beginning of the weight reduction course, at its end and in the period after the end of the weight reduction course). Microbiological analysis was performed by the plate method, where the number of KTJ/g stool of the probands was evaluated after cultivation. For each of the probands, one sample was analyzed in each phase of the experiment. For statistical evaluation, the averages of log KTJ/g from the stool of all probands within each phase of the experiment were used. At the same time, there was a detailed evaluation of the intake of basic nutrients and other food components of the diet from the dietary records of the probands within the individual periods of the experiment. At the end, a correlation analysis was performed between the observed parameters. During the experiment, there was a decrease in the intake of total carbohydrates, monoenoic and trans fatty acids (P<0.05). In the group of probands, a tendency to decrease total energy intake and increased fiber intake was also noted. As part of the reduction course, there was a decrease in the abundance of Bacteroides spp. and lactic acid bacteria (P<0.05). In contrast, the numbers of Lb were increased at the end of the reduction program. acidophilus and Lb. rhamnosus in the stool of probands (P<0.05). In addition, in the period after the end of the reduction course, there was an increase in the abundance of fecal Bifidobacterium spp. (P<0.05) and a reduction in the number of Enterococcus spp. in the proband group (P<0.05). Based on the detected changes in the abundance of the bacterial composition of the cultured taxa, a possible reduction in the body weight of the probands within the monitored experiment can be assumed.

Dietary habits of patients in the schizophrenic spectrum
Krůčková, Dominika ; Kalinová, Nelly (advisor) ; Pehr, Martin (referee)
The thesis deals with the dietary habits of schizophrenic patients and the effect of anti- inflammatory food on the levels of inflammatory markers in the blood. Patients suffering from schizophrenia are observed to have poorer eating habits compared to healthy controls. These patients are more likely to consume saturated and trans unsaturated fatty acids and less likely to include fruit and vegetables, unsaturated fatty acids or fibre in their diet. At the same time these patients have a higher consumption of foods involved in promoting chronic inflammation and thus possibly worsening the symptoms of the disease. The aim of this study is to evaluate the dietary habits of schizophrenic patients using a semi-quantitative frequency questionnaire and to compare them with a control group without a psychiatric diagnosis. Furthermore, based on the findings from the DII to select foods from the questionnaire that contain components of or are themselves included in the anti-inflammatory food index and to determine whether the frequency of consumption of these foods correlates with blood levels of inflammatory markers. According to the results of this work the diet of schizophrenic patients can be considered less healthy compared to the control group due to lower consumption of fresh fruits and vegetables,...

NUTRITION TRENDS AND EATING HABITS OF INFANT AND TODDLERS
Bayerová, Michaela ; Starnovská, Tamara (advisor) ; Fornůsek, František (referee)
This bachelor thesis deals with the issue of nutrition of children from birth to 3 years. The theoretical part is dedicated to general characteristics and official recommendations in the field of infant and toddler nutrition, in particular the introduction of complementary foods and the eating behaviour that the child adopts at this age and carries over into adulthood. In view of the growing trend towards alternative diets of young children, part of this thesis has also focused on this issue, as the possible withdrawal of certain nutrients can have fatal consequences for the developing organism. The practical part focused on mapping these trends. The research was carried out quantitatively by means of a questionnaire survey, which was mainly directed at the child's general approach to nutrition and eating habits. The questionnaire was disseminated through Facebook groups that bring together parents of young children. The aim is to determine the current perception of nutrition of parents of young children, whether they follow official recommendations in terms of introducing complementary foods and what are the current nutritional habits of young children.

Incidence of obesity in young school-age children
Balcarová, Kateřina ; Kytnarová, Jitka (advisor) ; Frühauf, Pavel (referee)
This master's thesis investigates the incidence of obesity in young school-age children, in two groups aged 6-8 and 10-12 years. Firstly, it summarises the current state of literature about obesity in children, secondly, the young school-age children are characterised and thirdly, it informs about healthy lifestyle in primary school lessons. The aim of this study is to determine the incidence of obesity in young school-age children, to assess their eating and exercise habits and to find out if they are guided towards a healthy lifestyle during lessons. The test group included 214 participants (132 girls and 82 boys). Data collection was divided into two parts: the first part included anthropometric measurements (height, weight and waist circumference) and the second part questioned children's eating and exercise habits by a survey. The results show a lower incidence of obesity in the examined group compared to the literature. However, a higher incidence of obesity in older children corresponds with existing literature. Regularity of having breakfast and consuming sweet drinks was significantly connected to the BMI Z-score value. Conversely, the association of BMI Z-score value with the distribution of physical exercise lessons (PE classes) per week was not significant. Education including healthy lifestyle...
