Background. It is well known that high-energy diet, rich in fat and carbohydrates, increases the risk of obesity. Preschool age is an important period to acquire the eating habits continued later in adulthood. Therefore, evaluation of child nutrition in kindergartens is especially important in the prevention of future obesity. Objectives. To determine the energy value and energy density of meals consumed...
Background. Antioxidant vitamins such as alpha-tocopherol (vitamin E), ascorbic acid (vitamin C), and beta-carotene (provitamin A), play a significant role in protecting the body from an excess of free radicals. The vitamin content of the diet is thus very important. Objective. To assess whether the dietary intake of vitamins A, C and E is adequate in a selected group of adolescents living in Warsaw...
Background. Since arsenic compounds have an affinity to thiol groups their greatest amounts can then be found in the tissues containing sulphur - rich proteins, like beta- keratin in skin, hair and nails. Accumulation of arsenic also depends on the macronutrient content in daily food ration. The deficiency and excess of both the protein and fat may contribute to a higher content of arsenic in the...
Background. Researchers suspect that the accepted adequate ascorbic acid plasma concentration is not being met even after dietary intake of the recommended amount of vitamin C. Current dietary intake recommendation in Poland is 60 mg per day for women and 75 mg per day for man (EAR), while in Western Europe and North America is higher and amounts to 75-90 mg per day. Objective. The paper aimed at...
Background. Food less frequently used to provide the necessary nutrients for the survival and the body begins to play a role, which it is not able to cope with, leading to a dysfunctional its use. In an era of obesity, excessive interest in his appearance and lean silhouette assigning too much significance relates to a growing number of young women. Young women due to a period of their procreative...
Introduction. A rich and natural source of readily assimilated dietary protein together with invaluable vitamins and minerals are fish, particularly the saltwater species. The quality of any given foodstuff is determined by its nutritional value, which in turn depends on the food type and methods used for manufacture, processing and storage. Many fish products contain fewer water soluble vitamins...
Flavonoids are a group of bioactive compounds that are extensively found in foodstuffs of plant origin. Their regular consumption is associated with reduced risk of a number of chronic diseases, including cancer, cardiovascular disease (CVD) and neurodegenerative disorders. Flavonoids are classified into subgroups based on their chemical structure: flavanones, flavones, flavonols, flavan-3-ols, anthocyanins...
Background. Diet is generally defined as a set of behaviors, on the choice of certain foods, their consumption, and it is conditioned by various factors. Each model is shaped feeding in a given place and time by repeated regularly eating and dietary habits. Polish migration to Greece contributed not only to change their place of residence, but also forced them to adapt to a new country. In the literature,...
Seafood is an excellent provider of protein with high biological values. Fish, shellfish and other aquatic organisms are appropriate for food and have world-wide importance. They‟re wonderful sources of high quality proteins, superior to those in red meat and poultry foods. The human dietary amendments that characterize the “nutrition transition” include every quantitative and qualitative change in...
Background. Balanced meals eaten by toddlers at nursery school play an important nutritional role in satisfying a child’s daily demand for energy and nutrients as well in preventing any dietary deficiencies or excesses from occurring. Objective. To evaluate the energy and nutritional value of children’s diets at nursery schools in Lodz, Poland. Materials and methods. Analyses were performed at 30...
The results of studies conducted so far in the field of supplementing Se deficiency in cow and goat diets demonstrate unequivocally the positive influence of supplements used on the improvement of the health status of animals and an important increase in the concentration of this microelement in the obtained milk. The positive influence on health is reflected in the increased antioxidative status...
A total of 150 one-day-old male broiler chicks (Ross 308) and 120 one-day-old female Muscovy ducklings were distributed over 15 and 12 pens, respectively. All birds received the same diet during the first period of life. Throughout the second period (36-56 days for broiler chickens and 43-69 days for Muscovy ducks) different source plant extracts were supplemented to the basal diet for each species;...
Introduction. Nitrates and nitrites commonly occur throughout nature as well as in foodstuffs. Their excess consumption can however pose health risks, for example, arising from methaemoglobinaemia or from the formation of N-nitrosamines. Objectives. To determine whether the levels of domestic nitrate and nitrite consumption are safe in Polish households during 2006-2012. Material and methods. Appropriate...
There is no doubt that cancer is not only a genetic disease but that it can also occur due to epigenetic abnormalities. Diet and environmental factors can alter the scope of epigenetic regulation. The results of recent studies suggest that O-GlcNAcylation, which involves the addition of N-acetylglucosamine on the serine or threonine residues of proteins, may play a key role in the regulation of the...
Background. Fish and marine animals fat is a source of unique long chain polyunsaturated fatty acids (LC-PUFA): eicosa- pentaenoic (EPA), docosahexaenoic (DHA) and dipicolinic (DPA). These compounds have a beneficial influence on blood lipid profile and they reduce the risk of cardiovascular diseases, atherosclerosis and disorders of central nervous system. The proper ratio of n-6/n-3 fatty acids...
