Purpose of the analysis. To investigate and to evaluate the influence of food products with increased biological value (“Tichė” mineral water and sour milk enriched with conjugated linoleic acid and probiotic cultures) on some laboratory blood test results of students who have attended the second year of Medicine studies at the Faculty of Medicine of Vilnius University in 2007/ 2008. Methods. Laboratory blood examinations were performed in the LDC of Vilnius University Hospital Santariškių Klinikos. In order to evaluate the possible effect of food products with increased biological value on digestive functions of the organism, questionnaires were distributed. In order to find out whether the additionally consumed food had any influence on biochemical blood indicators, actual student nutrition analyses based on standard 24-hour survey methodology were performed. Programs used for data processing and analysis were MICROSOFT EXCEL 2003, and SPSS 12 0. Results and conclusions. The ionized Ca concentration in the blood plasma of persons that were using “Tichė” mineral water increased reliably, while both ionized Ca and overall Ca concentrations were decreasing during a control test when only spring water was used. The examined medical students were sufficiently aware of the daily water amount that should be consumed and understand its significance to the physiological functions of the body. The majority of respondents (67.9 percent) were drinking tap water; however, if the water was bought from the shop, 81.8 percents of the respondents preferred its taste characteristics. Sour milk enriched with conjugated linoleic acid and probiotic cultures had a glucose-reducing effect. More significant cholesterol and glucose changes in the control group might have been determined by lower total fat concentration in the food including sour milk which did not contain the conjugated linoleic acid. The nutrition of the examined students was not balanced: too much fat and not enough fruit and vegetables were consumed. Vitamin C and fish or its products had some effect on the biochemical blood test results. |
