Phosphates containing food and their implications for osteoporosis
Šobáň, Jan ; Rambousková, Jolana (advisor) ; Černá, Milena (referee)
Phosphates containing food and their implications for osteoporosis Phosphates are salts of phosphoric acid resulting from the secession of three acidic hydrogen from it. Phosphates are found in natural foods such as nuts, legumes, cereals, meat and offal. Phosphorus is also being added to foods industrially for its' various chemical properties. From more than 1 500 "E's" I found 16 that contain phosphates and thus significantly increase the supply of phosphorus in the body. Usual daily intake of phosphorus is about 1 g. Increased intake of phosphorus forms an acidic environment in the kidney and calcium phosphate complexes, and thus leads to calcium removing from the body and bone demineralization. "E's" containing phosphates are frequently found in meat products, processed cheese, confectionery, bakery products, cola beverages, frozen and instant foods. Most commonly used additive is E-338 phosphoric acid. Osteoporosis is a systemic skeletal disease characterized by a small amount of bone mass and de- terioration of bone micro-architecture resulting in increased fragility and fracture risk. The Czech Republic declares to have 600 000 patients treated for osteoporosis.

Probiotics and prebiotics in the
Šrámková, Kateřina ; Rambousková, Jolana (advisor)
Words probiotics and prebiotics ( derived from the Greek " Bios " meaning life ) was recently tem of unknown. Today, however, regards the concepts increasingly often as professionals and the general public. Probiotics and prebiotics They have a wide scope and their use in medicine grows . Their great advantage is that the so-called " substances in the body own " , so they are a natural part of a healthy human organism. Recently, more and more attention is paid to physiological intestinal microflora. The effort is primarily the influence of the optimal composition. The first attempts to date back to the early 20th century, when the 1908 Nobel Nobel Russian scientist Ilya Mechnikov published a theory that consumption of fermented dairy foods containing lactobacilli , contributes to longevity . The term " probiotic " was first used in 1965 , as the opposite of the term " antibiotic " . What is the effect of the probiotic bacteria ? Benefits can be found in large numbers. Generally, the Probiotics promote the growth of physiological intestinal microflora * flora and prevent the growth of pathogenic organisms . In so učasné underway a number of clinical studies , investigating the possibility of therapeutic use of probiotics in clinical practice. Along with prebiotics can be successfully used them in the...

Sources and Importance of Natural Antioxidants for Human Health
Frühaufová, Lenka ; Rambousková, Jolana (advisor)
Existence of free radicals as participants in biological processes, scientists expected at the beginning of the 20th century . Given the characteristics of these substances, their instability and very short half-life , however, was their exploring challenging to impossible , and therefore a deeper learning to occur with the development of relevant research methods. Hand in hand with uncovering secrets and patterns of oxidative damage to biological macromolecules occurred to focus attention also to a system that is capable of this action prevent and maintain a balance in the cell , the antioxidant system . It is formed diverse group of substances of enzymes catalyzing redox reactions through plasma proteins to substances that the human body is not capable of self- produce and must be obtained from food . The subject of the research are now interaction of both systems and applications, primarily acquired knowledge into practice. What is the role of free radicals in the pathogenesis of disease states such as cardiovascular disease or malignancy ? How to participate in prenatal damage to the fetus ? They are involved in the aging process ? Together with obtaining answers to these and many other questions are logically appears another : we can use substances having antioxidant effects in preventing or treating...
