Background. Numerous studies attest to the role that inappropriate food product groups in the human diet, including children and adolescents diet, leading to abnormal intakes of many important nutrients, such as minerals. Objectives. These studies were undertaken to assess the coverage of the recommended values for chosen minerals by 205 children and adolescents between the ages of 4 and 20 years, grown up in Krakow orphanages. Materials and Methods. Sodium, magnesium, zinc, iron, copper, calcium and potassium concentrations in 112 diets of children and adolescents from 7 selected orphanages in Krakow in every season of the year were performed using AAS method. Results obtained were compared to recommended standards in Poland. Results. Intakes of calcium and potassium were usually too low whilst adequate levels of dietary magnesium and calcium were seen only for the youngest children. Recommended dietary levels of zinc were met in all cases and mostly also for iron and copper. Sodium intakes were however excessive. Conclusions. The study demonstrates that regular a monitoring and adjusting of the diet is necessary for the assessed children and adolescents in order to correct dietary abnormalities.

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 studying a correlation between composition of nutrients in daily diet and plasma vitamin C levels in university students. Materials and methods. This study examined diet composition and the nutritional status of ascorbic acid in plasma of 120 university students in Szczecin, Poland. Ascorbic acid was determined in blood plasma using HPLC method. The information concerning diet composition was collected using the method of “7-days food record” prior to blood collection. Results. Plasma ascorbic acid deficiency (<40 μmol/L) was observed in 23% of women and 28% of men. The average plasma ascorbic acid concentration was 48.65 μmol/L in women and 45.61 μmol/L in men. The average intake of vitamin C in women with observed deficiency was average 46.55 mg/day, whereas in men it was 48.56 mg/day. Conclusions. The recommendation of dietary intake of vitamin C in Poland is low in comparison to other countries. Population- based studies are necessary to determine the actual demand for vitamin C in various population groups in Poland.

Ocena programu „Owoce w szkole” została przeprowadzona wśród uczniów klasy III (9 lat) z 58 losowo wybranych szkół podstawowych z 5 wybranych województw: pomorskiego, opolskiego, wielkopolskiego, podkarpackiego, mazowieckiego. Wybrane województwa były reprezentatywne dla regionów Polski, czyli północy, południa, centrum, wschodu i zachodu. Badanie przeprowadzono w szkołach przed rozpoczęciem dystrybucji owoców i warzyw (październik 2010 r.) oraz pod koniec dystrybucji owoców i warzyw (maj-czerwiec 2011 r.). Badanie przeprowadzono w 38 losowo wybranych szkołach podstawowych uczestniczących w programie „Owoce w szkole” (grupa interwencyjna) oraz w 20 losowo wybranych szkołach nieuczestniczących w programie (grupa kontrolna). Spożycie owoców i warzyw przez uczniów zostało ocenione metodą 3-dniowego zapisu w dzienniczku spożycia. Pod koniec programu „Owoce w szkole” spożycie owoców, warzyw oraz owoców i warzyw ogółem w dni szkolne oraz dni szkolne i weekendowe łącznie było istotnie wyższe w grupie badanej niż w grupie kontrolnej, ale wciąż poniżej zaleceń. Pod koniec programu całkowite spożycie owoców i warzyw w dni szkolne w grupie badanej było 21% wyższe w porównaniu z grupą kontrolną. Wnioski: Wyniki oceny wskazują, że program ma duży potencjał i jest odpowiednim narzędziem do pracy z dziećmi w celu poprawy w przyszłości ich nawyków żywieniowych, związanych z większym spożyciem owoców i warzyw.

Utilizing the results of the Household budget surveys covering the period of August 1989 — December 1990 and referring to the employees households the effect of the „marketisation" of food economy on the expenditure on food and food consumption was examined. It was shown that „marketisation", which began on August 1 1989 resulted in a dramatic increase in the expenditure on food in the households of employees. The expenditure was growing both in absolute and relative terms leading to an increase in the proportion of food expenditure in total expenditure. Although the of employees households were paying more and more for food they were at the same time forced to decrease its consumption, which resulted in a significant reduction in the energy and nutrient content of the household diet.

Background. In recent years, changes to adolescent life style and nutrition are becoming increasingly apparent. One of the ways in which this can be observed, is in an unbalanced daily intake of dietary minerals, where some intakes are in excess whilst others are deficient. Normal growth and development can thereby become adversely affected. Objective. To determine daily dietary intake levels of calcium, magnesium, phosphorus, sodium, potassium, iron, zinc and copper together from their various foodstuff sources in the daily diet of a defined group of adolescents. Material and methods. Subjects were adolescents aged 16-19 years attending the technical college at the Polish town of Kamień Pomorski; being under the jurisdiction of the Western Pomeranian Province (voivodship). The study tool was a survey of food that had been consumed within the last 24 hours, from which the amounts of mineral elements in any given menu, so chosen, could thus be estimated. Results. Average daily potassium intakes were found to be generally low; less than 2350 mg and 1800 mg respectively for girls and boys compared to recommended values. This was coupled with high sodium intakes, where respectively, girls and boys exceeded recommended values by 2.1 and 2.8 times. Excess intakes of phosphorus, iron and copper were also observed in boys; respectively 500 mg, 4 mg and 2 mg. Some subjects showed insufficient intakes of calcium and magnesium i.e. 63%-80% below EAR (Estimated Average Requirements). The main source of calcium was found to be ripe cheeses, milk and fermented beverages. In both groups the main dietary sources of magnesium, sodium, iron and copper were bread. Girls diets showed that phosphorus and zinc mostly came from eating ripe cheeses and poultry, whereas potatoes were the main source of potassium. The boy’s daily dietary intakes demonstrated that phosphorus and zinc originated from eating bread and potatoes. Significantly lower amounts of phosphorus, sodium, iron and zinc were however consumed by girls compared to boys. Conclusions. The mineral content of the subjects’ daily diet was found to be substantially unbalanced.

The purpose of the research was to develop the optimal palm oil/rapeseed oil blend for shallow and deep frying for household and commercial use as seen from the nutritional and technological points of view. In piloting experiment, fatty acids composition by GLC, oxidative stability by Rancimat1200C as well as several other indicators (e.g. IV, PV, FFA) were measured. It was found that 1:1 rapeseed/palm olein blend improves both nutritional (due to rapeseed oil) and physico-chemical indicators (due to palm olein) in the final product. Oxidative stability of the blend was improved up to 60% in comparison to rapeseed oil. Rapeseed oil, palm olein IV62 and their blend (1:1) were used in potato slices frying. Sensory assessment as well as PV determination showed an improved quality of chips fried in the prepared blend.

The aim of the study was to assess the frequency of consumption of selected groups of foodstuffs with varying energy value by patients of the „Dom Zdrojowy" sanatorium in Ciechocinek (Poland). The survey included 100 persons, out of which 80% were obese individuals (OB), while the others were patients with cardiovascular diseases (CVD). Products with lowered energy value, especially cottage cheese, milk, "light" yoghurt, as well as tea and coffee without sugar were on average consumed rather frequently. Obese patients, from among women constituted 80%, paid attention to fat content in their daily diet.

Quantity and quality of fat in every day diet influence human health. Recently particular attention is payed to trans fatty acids composition in ingested food. Modern, no time consuming, convenient food is widely used now. Seventeen chosen products like dry soups or sauces mixes from the market in Poland were analysed to estimate fat concentration and fatty acids composition including trans fatty acids. The products contained different amount of fat, from about 3g/100g to 24g/100g of product. The fat concentration as well as fatty acids composition varied dependently on the kind of product and producer too. The dominated group of fatty acids in all analysed samples were saturated fatty acids (up to 50%). Monounsaturated fatty acids occured in the range from 15 to 40%, while polyansaturated from 2 to 6%. Four trans fatty acids were identified: 18:1, 6-trans, 18:1, 9-trans, 18:1, 12-trans, and 18:2, cis-9, trans-12. Only 18:1, 9-trans.

The products of plant origin are a rich source of biologically active substances, both nutritive and referred as anti-nutritive. A large group of these compounds are substances with antioxidant activity that fights against free radicals. In the family of Brassicaceae vegetables, Brassica, is the largest and most widely consumed a group of plants in Europe and all over the world. They are characterized by different levels of nutrients. However because of their large and frequent consumption, they may become a significant source of nutrients and bioactive compounds in the daily diet. The beneficial effects of Brassica vegetables on human health have been somewhat linked to phytochemicals. They prevent oxidative stress, induce detoxification enzymes, stimulate immune system, decrease the risk of cancers, inhibit malignant transformation and carcinogenic mutations, as well as, reduce proliferation of cancer cells. Brassica vegetables contain a lot of valuable metabolites, which are effective in chemoprevention of cancer, what has been already documented by numerous studies. Due to the presence of vitamins C and E, carotenoids and antioxidant enzymes such as catalase, superoxide dismutase (SOD) and peroxidase, these vegetables are considerable source of antioxidants, and due to the presence of polyphenols and the sulfur-organic compounds exert also antimutagenic action. Moreover, these vegetables are also rich in glucosinolates, which are unstable compounds and undergo degradation into biologically active indoles and isothiocyanates under the influence of enzyme presented in plant tissues- myrosynase. These substances through the induction of enzymatic systems I and II phase of xenobiotics metabolism may affect the elimination or neutralization of carcinogenic and mutagenic factors, and consequently inhibit DNA methylation and cancer development. Despite many healthy benefits upon eating of cruciferous vegetables, it has been also seen a negative impact of their certain ingredients on the human body.
