A method of the classification of natural mineral and spring waters and maximum admissible concentration (MAC) levels of metals present in such types of waters are regulated by Commission Directive 2003/40/EC, Directive 2009/54/EC of the European Parliament and of the Council and Ordinance of Minister of Health of 30 March 2011 on the natural mineral waters, spring waters and potable waters...
Background. Many studies demonstrate that the elderly consume a nutritionally inadequate diet that includes deficiencies in macro- and microelements; iron and zinc being significant examples of the former. Objectives. To assess the adequacy of dietary iron and zinc intakes in the elderly. Material and methods. The study was conducted on n=102 elderly persons, participating in the PolSenior Project,...
Background. Vegetarian diets, by definition, are rich in vegetables and so may have high levels of nitrates, that can elicit both positive or negative effects on the human body. Exposure to nitrates can thus be potentially higher for this population group. Objective. To estimate dietary nitrates intakes in Polish vegetarians and compare these with the Polish average. Material and methods. A sample...
Background. Numerous studies have demonstrated acrylamide to be both neurotoxic and carcinogenic. At present it is widely recognised that acrylamide is mainly formed through the Maillard reaction from free asparagine and reducing sugars. The major sources of dietary acrylamide are potato products, processed cereals and coffee. Objective. To optimise and validate an analytical method for determining...
Background. Some of the main nutritional reasons for recommending a Mediterranean diet is to prevent metabolic diseases arising through free radical formation. A key constituent compound is β-carotene which, amongst the carotenoids, displays the greatest provitamin A activity as well as possessing significant antioxidant properties. Objectives. Principally, to determine the relationship between serum...
Background. Within the medical facilities provided by state healthcare services, a universally applied technique for patient diagnosis and treatment relies on ionising radiation; for example in radiotherapy and X-ray (ie. examination). Human exposure to such radiation is not however entirely free of associated health risks. Objectives. To determine and estimate the numbers and types of X-ray based...
Phenolic compounds are a group of key plant metabolites found abundantly in fruit and vegetables. Because of their antioxidant properties, they play a significant role in preventing various degenerative illnesses, tumours or cardiovascular disease. In nature, they are present in foods mainly as esters, glycosides and polymers which need to undergo enzymatic hydrolysis in the digestive tract or by...
Background. Selenium belongs to important microelements. Numerous studies have revealed relationships between its deficiency and occurrence of diverse illnesses, but the question of the proper form and dose of Se-supplementation still remains unsolved. Objective. In the present study the influence of different selenium compounds on blood morphology and biochemistry as well as on phagocytic capacity...

Background. Being acquainted with nutritional recommendations does not necessarily imply that they are fully understood, nor on how they can be applied when correctly planning an adequate diet. Objective. To determine whether children can recognise single portion sizes of various foodstuffs and to test their ability for planning a daily menu in accordance to the guidelines from a Food and Nutrition...
Background. Evaluation of the biocidal activity of chemical disinfectants and antiseptics according to European Standards (EN) is based on determination of the reduction of the number of viable test microorganisms under defined conditions. Objective. The objective of this study was to investigate whether reducing the neutralization time required following declared product contact times for the tested...
Background. The formative years of adolescence are a crucial time for developing eating habits which, amongst other factors, are determined by personality traits. Objective. The aim of the study was to estimate eating behaviour in a group of middle school pupils according to gender and locus of control (LOC). Materials and methods. Subjects were n=200 boys and n=200 girls, aged 14-16 living in the...
