Monitoring of Phytoestrogens Expression to the Milk and Milk Products
Watzková, Jarmila ; Rittich, Bohuslav (referee) ; Doležal, Petr (referee) ; Omelková, Jiřina (advisor)
Phytoestrogens are very intensively studied in recent years because they show different pharmacological effects on human health. For example, it was demonstrated that phytoestrogens reduce the risk of certain cancers (breast, prostate or colon), act as antioxidants in the body and affect the activity of certain enzymes. In addition, also it was demonstrated number of positive effects of soybean phytoestrogens on the health status of women in the menopause, such as reducing the risk of atherosclerotic cardiovascular disease or osteoporosis. Various technologically processed soy beans are important part of the feed rations mainly for high-lactating dairy cows, because they are a valuable source of the energy and high-quality protein, despite their negative effect on reproductive performance. Phytoestrogens consumed from the feed rations are hydrolyzed in the rumen of dairy cow and together with their metabolites are absorbed in the small intestine into the blood. They can be excreted from the body in urine or milk. From this perspective, cow's milk may become a source of phytoestrogens substances, especially equol in the human nutrition. On the other hand, some research results suggest possible potential risks associated with phytoestrogens intake in the diet on human health. At the some age (infants and young children) and group (vegetarians) categories may be dietary intake of phytoestrogens undiserable. According to most experts, a beneficial effect on human health prevail the potential risks. However, the risks associated with phytoestrogens intake in food can not be ignored and therefore phytoestrogens are still actual problem in the field of scientific research.

Milk and dairy products and their importance in nutrition
Šubertová, Hana ; Vítová, Eva (referee) ; Omelková, Jiřina (advisor)
This bachelor thesis is engaged in the analysis of the composition of the milk, its creation, origin and source and furthermore it is engaged in the evaluation of the beneficial and harmful properties of milk. Another aspect of this thesis is reasoning about why we should consume milk and whether it is even beneficial to health. In the following part of this work, the literature review is created about about how milk and different products affect human nutrition and the thesis is studying the problematics of milk consumption. The next part of my thesis describes the course of "milk route", which explains what is happening to milk as a raw material, then the technology of production and processing of milk, milk products and semi-finished products and also contains the comparison of my measured data with the standardized data, or the data on the packaging.

Rybárová, Petra ; Váchová, Alena (advisor) ; Kovaříková, Miroslava (referee)
This thesis is concerned on the theme Milk and dairy products in nutrition of pupils aged 11 to 15 years. The theoretical part is based on the chemical composition of milk of general aspect and there are characterized some chosen kinds of dairy products and their effects on human health. The practical part is concerned on the research of being some statistically significant differences in consumption of milk and dairy products of the point of view of gender, age and access to milk and diary products in the families. The research is further based on the finding of the levels of probands'knowledge about the composition and the influence of milk to the human organism. The research sample is formed by 240 pupils of Secondary school in Domažlice, Komenského 17. The results show neither the gender, age or access to milk and diary products in the families do not affect the consumption of milk and dairy products of individual probands. The education unit whose aim is to increase the knowledge about milk of second graders in elementary schools is proposed on basis of identified facts.

Milk food at school organizations in the Czech Republic and EU
KLUIBER, Petr
Milk and milk nutrition are an important part of the balanced diet for children. Milk contains proteins, which are easy to absorb and which are necessary for growth, development and the renewal of tissues. The fat contained in milk is a rich source of vitamins and carbohydrates, which are an easily available source of energy. What is more, milk also contains a number of minerals, out of which calcium is assigned the greatest importance. Because of the dangers caused by the insufficient intake of calcium, this fact is being taken in account in school catering. The impact of the school catering on the health and further development of children is considered largely important in all the EU coutries. However, the regulations of school catering are different in each country. These regulations range from non-biding governmental recom-mendations on the size of portions or meals offered to the full restrictions of certain products and the national system of standards, which are to be found for example in the Czech republic, where every school canteen has to follow the standards of the so called "basket of consumer goods". Apart from school catering, there are projects which support the consumption of milk and milk products. The most significant of these projects in the Czech republic is the project School milk. It has been implemented in 1996 and it is run by Laktea company, which restarted the supply of milk and milk products to children in cooperation with schools. The School milk project won the support of the Czech goverment in 1999 and, after joining the EU, the project has started develeping fully. The project School milk can be considered successful and desirable as it started with 426 participating school, but there are 3000 schools involved in it today. Similar projects are running in many other EU countries, where each member country can choose for themselves for which products from the EU list they will get the funding. They also have the opportunity to change their projects depending on their needs. Apart form this, the participating countries can support the project with other resources and can provide the milk for full price, partially subsidized or for free. Equallly, they have the right to change to containt of certain milk components, such as to lower the percentage of fat.

COWS MILK AS A NATURAL SOURCE OF IODINE IN HUMAN NUTRITION
VÍTKOVÁ, Lucie
This thesis deals with the importance of milk as a natural source of iodine in human nutrition. The thesis provides a data of the consumption of milk and milk products and their contribution to the protection needs iodine for students and employees of the University of South Bohemia in Ceske Budejovice. The experiment includes a total of 60 people (20 men and 40 women). Empirical data wasobtained within the grant project named GAJU 011/2013/Z and NAZV QH 81105. Data of consumption of milk and milk products were obtained through questionnaires. For men, average weekly consumption of milk was 826.5? 835.1 ml (118.1 ml per day) and for women 912.4? 783.9 ml (130.3 ml per day). Average consumption of yogurt for men was 361.0? 401.4 g per week (51.6 g per day), for woman 428.4? 338.8 g per week (61.2 g per day) and average consuption of cheese was for men 263.0? 240.5 g per week (37.6 g per day) and for woman was 260.2? 226.5 per week (37.2 g per day). Through the milk and milk products tested, men average 81.6 g of iodine per day, woman adopted 93.4 g. According to the results, the amout of consumed milk and milk products was lower than the nationwide average, but still covered more than half of daily iodine needs. The thesis presents the data of the iodine concentration in urine for students and employees of the University of South Bohemia in Ceske Budejovice (n=62) as an indicator of iodine supply to the organism. The average iodine content in urine of all subjects (men and women) was 230.4? 171.3 gl-1, for men (n=21) reached 244.6? 195.2 gl-1, for women was 223.2? 159.8 gl-1. Results of the average iodine content in urine reflected the physiological range, i.e. for the students and employees of the University of South Bohemia was supply of iodine in organism sufficient. The thesis also provides information about the amount of iodine in asamples of cow´s milk on a selected farm (n=50) of the Jihocesky region, the Plzensky region and Vysocina during the years 2011 - 2013. Samples of cow´s milk were obtained in collaboration with the Central Laboratory of dairy Madeta a.s in Ceske Budejovice and Veterinary Centre s.r.o Susice. In 2011, the average concentration of iodine was 321,0? 337.8 gl-1, in 2012 was concentration of iodine 298.8? 290.8 gl-1 and in 2013 was 234.7? 116.1 gl-1 also otherwise: in all years was it was determined that there was an abundance of iodine. The highest values (315.6? 305.1 gl-1) of iodine was in the Jihocesky region. In Vysocina a lower average level of the iodine was detected (9.5 %), as well as in the Plzensky region where the amount of iodine in milk was lower by 53.7 %, compared to the South Bohemia region and 48.8 % compared to the Vysocina region.
