Diabetic versus eating in public establishments (candy store) - production of ice cream for diabetics.
KRČMÁŘOVÁ, Lucie
In my bachelor thesis I deal with one of the most common diseases of civilization, diabetes mellitus. The theoretical part contains historical facts, information about anatomy of the pankreas, epidemiological characteristics and types of diabetes, as well as diagnosis, treatment and complications of this disease. In the part dealing with nutrition, I deal with macronutrients and micronutrients found in diabetic nutrition, glycemic index, recommendations for diabetics and the main topic of my bachelor thesis, sweeteners. In the practical part I deal with the production of two types of fruit sorbets (strawberry and raspberry) with the addition of artificial sweetener - sucralose. This ice cream is tested on five healthy volunteers and five volunteers with 1. and 2,. type of diabetes compared to strawberry and raspberry sorbet with sugar. The result of the research is to found out how individual types of the ice cream affect the glycemic curve of healthy volunteers and volunteers with diabetes.

Vliv vybraných potravin na hladinu glykémie
Habánová, Veronika
The thesis deals with the measurement of glucose levels at regular intervals in a selected group of volunteers after the consumption of breakfast cereals in combination with milk products. The theoretical part is devoted to the basic components of the diet and their digestion and metabolism. It also deals with the regulation of blood glucose level, methods for measuring glycemia, disorders related to metabolism of carbohydrates and the concepts of the glycemic index, glycemic load. The aim of the practical part was to find out how your chosen breakfast cereal in combination with dairy products have an effect on blood glucose levels in a selected group of volunteers. 16 students of the Mendel university in Brno were attended the experimental measurements. The students measured on the InBody, in order to determine composition of the human body. The level of blood glucose was always measured in time 0 (fasting), 60, 90 and 120 minutes from the beginning of the consumption of the food. Statistically significant difference was shown from measured values of blood glucose in 60. and 90. minute between the glucose solution, and breakfast cereals (P < 0.05).

Glycaemic index of food and its determination
Špiláčková, Aneta ; Kouřimská, Lenka (advisor) ; Monika, Monika (referee)
The purpose of this thesis was to elaborate a literature recherche on a given theme with focus on analytical methods to estimate the glycaemic index of food.
This bachelor thesis is divided into three main chapters. First chapter describes general characteristics of glycaemic index of foods and influencing factors. In this chapter states the influence of high and low glycaemic index foods on health, wellbeing and glycaemia in humans. Subsequent part of this chapter is dealing with many other factors that influence the absolute amount of glucose in blood in 2 hour interval after meal.
Chapter two initiates into conventional and continual methods of glycaemia measurement.It highlights the advantages and limitations of each of these methods.
Third, the most extensive chapter is dealing with methods of glycaemic index assessment. This chapter is broken down into two parts. First part specifies clinical methods that are also called in vivo, and the second part is focusing on in vitro methods. Clinical methods require blood glycaemia measurement in healthy volunteers after consuming a test meal. With this method we are able to reliably state the glycaemic index of certain foods.
The limiting factor of this method is that it is rather time-consuming and it requires higher financial means. These measurements take place under a strict control, according to guidelines and only with the approval of ethical committee.
Analytical methods are based on simulation of human digestion. In vitro methods use hydrolysis index to obtain the glycaemic index. The final values are only an assessment of glycaemic index of given food. Other method that is described is measurement of fast and slowly available glucose and starch in given test foods. It is based on measurement of released glucose from the test food with HPLC method, time incubation and standardized conditions. Last method includes partitioning of a test food, and subsequent HPLC analysis of carbohydrates and sugar alcohols. The HPLC results are processed in artificial neural network to reveal glycaemic index values.
The advantages and disadvantages of each mentioned method are stated in conclusion of this work. I compared and contrasted reliability, elaborateness, budget demands
of analytical methods with clinical assessment methods.

A type 2 diabetes nutrition - recommendation and reality
MÍČKOVÁ, Veronika
The given bachelor thesis elaborates on the issue of type 2 diabetes and the approach of the patients, suitability of their education about the recommended diet and formation of potential risks as a result of this disease. Two main objectives were set for this study. The first objective consisted of a survey on education of the patients about the recommended diet and health risks if they fail its observance. The second objective analysed the survey which was conducted in order to reveal factual eating habits of these patients. The first and purely theoretical part. The second part focuses on qualitative research which was conducted by using a semi-structured interview as a data collection method. The focus group consisted of six respondents - two men and four women. The gathered facts reveal that the education and knowledge instructed by the doctor is more or less satisfactory. Four respondents out of six indicated to be satisfied with their doctor. Only one respondent was utterly unsatisfied and one assessment provided by a female respondent was considered as biased considering her old age and a long course of the illness. Her negative approach towards the doctor´s education was not taken into account either, due to the fact that the given patient must have changed several doctors during her lifetime. The results also demonstrate that the majority of respondents observe a recommended diabetes diet, eating at least five or six meals a day. According to their answers, most of them eat vegetables, lean meat and whole-grain bread and drink water, tea, or coffee. Five respondents out of six prioritise the recommended food preparation techniques, such as steaming, stir-frying and stewing. They all agree on types of food they try to avoid in majority sweets. Then the conducted survey points out situations during which the given diet is not observed. However, these situations are exceptional, so they should not be regarded as a non-observance of the diet provided that the answers given are truthful. Furthermore, the respondents observe, or try to observe, the diet recommendations, as evidenced by their regular doctor´s appointment and steady glycaemic index. Finally, the given research included two questions which were supposed to highlight the possibilities of the respondents depending on their place of residence. The first question should indicate the variation in size of the place and number of inhabitants. It was proved that the size did not have a remarkable influence on the diabetes education. The second question focused on assortment and price of diabetes food products. The bigger the agglomeration is, the cheaper and wider assortment of these products can be found. The final assessment based on interviews and results obtained was more or less positive and in comparison to other publications specifying the same recommended diet reached similar conclusions.

Vliv konzumace vybraných potravin sacharidové povahy na hladinu krevní glukózy
Langhammerová, Lucie
This thesis deals with the measurement of blood glucose levels after consumption of selected foods (glucose solution, milk chocolate, rice sandwiches with corn, fruit snacks with apricots and broken buckwheat multigrain bread) at regular intervals. The first part of this thesis is pursued to the literature review, which provides a comprehensive overview of the metabolism of carbohydrates, fats and proteins. It also discusses the differences in the carbohydrate metabolism of healthy people with diabetes type 1 and 2 It acquaints the reader with the concepts of blood glucose, glycemic index and glucose-tolerance test. The practical part includes the measurement of glucose in capillary blood and questionnaire survey concerning state of health, eating habits and the disease incidence in a selected group of volunteers. The experiment involved 12 students of Mendel University in Brno. Their blood glucose levels were measured at regular intervals (0, 30, 60, 90 and 120 minutes) after ingestion of the food. The glucose was chosen as a standard. From the measured values were calculated glycemic indices, which represented 100 for glucose, milk chocolate 40+-17,7, sandwiches, rice with corn 76+-25,8, fruit snacks with apricots 49+-17,9 and multigrain bread buckwheat 68+-21,3. The results were statistically processed and the effect of individual foods tested on blood glucose was evaluated.

Eating Habits of Type 1 Diabetes Mellitus Patients
KRÁLOVÁ, Kateřina
The topic of my bachelor work is Eating Habits of Type 1 Diabetes Mellitus Patients. The Diabetes mellitus is a chronic illness, which is for its high incidence in the population regarded as disease of civilization. There are approximately 15 000 000 people with diabetes type 1. according to the International Diabetes Federation, which is little over 7 % of the total number of diabetics. The aim of the bachelor work is to describe, through the research, eating habits found at patient type 1 diabetes and to map the reasons that lead to noncompliance of diabetic diet set by physician. So to answer the research questions: "What are the eating habits type 1 diabetic?" and "What are the reasons for patient to not follow recommended diet?" The research part is elaborated in the form of qualitative research using semi-structured interview. Total of seven diabetic patient in the age range from twenty-three to fifty years, provided the interview. The data were obtained from patients who were treated at diabetes physician MD Lenka Dohnalová in the diabetes clinic at a hospital in České Budějovice. Interviewing these patients was not purposely carried out in the presence of nurses or diabetologist in order to prevent degradation of the answers of interviewed persons. As result, the respondents were not afraid to tell the truth and the information obtained was as objective as possible. Patients were helpful and willing to give interviews. Respondents did not mention their names so the entire interview is anonymous. Everyone agreed to provide an interview and also agreed on being recorded. Two research questions were set and answered on the basis of anonymous interviews. Research Question No. 1: 1st What are the eating habits of type 1 diabetes patients? It is obvious that patients with diabetes were told that they should keep track of the number of carbohydrates eaten in the food. Six respondents use replaceable units to achieve it, 12 grams of carbohydrate equals 1 replaceable unit. One respondent does not recalculate the carbohydrates in the food on replaceable units, but is familiar with using the grams of carbohydrates. I was surprised by the answer on the special diet, a product formerly known as "dia," I did not expect that it consumes only one respondent. Beyond my original expectations is also surprising fact that neither of the respondents check the glycemic index in their food. Research Question No. 2: 2nd What are the reasons not to comply the recommended diet? It is obvious that patients try to comply the regime. None of the respondents currently have a problem with self-monitoring, application of insulin or consumption of food and beverages at school or at work. One respondent stated that she had these problems at work, and she is now on a disability pension. The results of the research are useful for health professionals who take care of diabetic patients. Intended use of the work in practice: Issuing this in diabetes clinics should support and enhance awareness of patients with diabetes about their disease.
