The aim of the study was to assess the effect of cultivation intensity on the Ca, Mg, Zn and Fe contents in winter wheat grain, flakes and bran. The initial material for the study comprised grain, flakes and bran of two winter wheat cultivars Kobiera and Bogatka. These cultivars were from two strain testing stations located in Lower Silesia, Zybiszów and Tomaszów Bolesławiecki in the years 2007-2008. The cultivation was conducted on two intensity levels: lower and higher The mineral content was determined by the flame atomic absorption spectrometry (FAAS). The investigation showed that the level of cultivation had no significant effect on the content of all minerals analyzed in grain, flakes and bran. The Ca content in wheat grain, flakes and bran was stable, regardless of varieties, weather conditions, tillage intensity and cultivation place, furthermore soil conditions significantly affect Fe content in wheat grain, flakes and bran.


Intake of fruit and vegetable among 50-year-old population of Wroclaw and the impact of education level on the consumption of fruits and vegetables was assessed. The study group was 50-year-old, 1520 inhabitants of Wroclaw (879 women and 641 men), who participated in 2008 in the Cardiovascular Diseases Prevention Program organized by the Health Division of the Municipal Office in Wroclaw. To assess fruit and vegetable intake Food Frequency Questionnaire (FFQ) was used. The mean daily intake of vegetables and fruit was 289,4 g for women and 209,1 g for men. Women consumed significantly more vegetables, fruits, and the amounts of fruits and vegetables compared with men. The impact of educational level on fruit and vegetable consumption in the study group was found.

Low sociodemographic status positively correlates with the risk of lung cancer. Nutritional status assessed during diagnosis of cancer may be a useful predictive factor for response to therapy and influences the quality of life and life expectancy after oncological therapy. The aim of this study was to assess the sociodemographic and nutritional status of patients. Lower Silesian Centre of Lung Diseases, diagnosed with lung cancer. 81 cases and 125 subjects formed the control group were included in this study. The questionnaire about sociodemographic status was performed among all respondents as well as MNA questionnaire and anthropometric measurements for evaluating nutritional status. Lower level of education, lower employment status and more frequent tobacco addiction was found in patient group then in control individuals. Nutritional status of patients was worse than the control group, which has been demonstrated mainly through a MNA questionnaire and arm circumference measurements. The risk of malnutrition or diagnosed malnutrition found in most patients assessed by MNA test may increase the likelihood of complications during treatment.


Beverages especially mineral waters are considered as one of the best nutritional sources of silicon. The aim of this work was to determine the silicon content in bottled mineral and spring waters, as well as in orange, apple, grapefruit and mixed fruit juices available on the market. The electrothermal atomic absorption spectrometry (GF-AAS) was used for the silicon determination. The silicon levels in mineral waters ranged from 3.33 - 30.05 mg Si/dm3, in spring waters ranged from 3.66- 11.23 mg/dm3, and in fruit juices ranged from 0.21- 1.93 mg/100g.

The risk of interaction between dietary supplements, herbal drugs and synthetic drugs increases when patients are treated chronically, e.g. due to impairment of central nervous system (CNS) - depression, psychotic disorders, Parkinson's and Alzheimer's diseases. On the basis of scientific literature, there was shown that simultaneous intake of antidepressants, antipsychotic drugs and herbal drugs or dietary supplements containing: St. John's wort, valerian root, ginkgo biloba leaf, hops, and food ingredients: dietary fiber or folic acid, may lead to interactions. Dietary fiber supplementation should be applied carefully during treatment of Parkinson's disease and in case of Alzheimer disease treatment - supplements containing ginkgo biloba leaf can increase the risk of interaction. Knowledge of these interactions is essential in effective treatment of this illness. However this area of science should be verified constantly due to growing number of new products registered as a supplements - often with complex composition.


In 2006 morbidity from cancer in Poland was almost 126,000 new cases and there were about 91,500 deaths. Among women older than 65 years the most frequent cancer death was lung cancer. Among men death from lung cancer decreased, in connection with smoking cessation. Smoking cessation is the most important point of first prevention in lung cancer disease. Nutritional habits are also key points of prevention. It was claimed that omega-3 fatty acids have a positive role in prevention of this type of cancer. There have been a lot of studies on isothiocyanates, and the protective role of this group of compounds was proved. In epidemiological and experimental studies it was confirmed that selenium had anticancer activity. Nutritional components supply which is compatible with demand can lead to decreased risk of lung cancer development, but only if it is connected with a healthy lifestyle.


An increasing pace of life and a lack of time for meals preparation at home, observed in many countries worldwide, have led to an increased consumption of convenient food products. This term refers to highly processed food products that are either ready-to-eat or may be consumed after short culinary processing. Convenience foods include: dinner courses, salads, cereals, creams, broths, pizzas, roasts, as well as frozen products ready-to-eat after short heat treatment. The aim of this study was to assess the fat content and fatty acids composition of frozen products belonging to convenience food. Material for analysis comprised of 30 following food products: fish and seafood products, pizza, casseroles and meat products. The fat content was determined using Folch method and the fatty acids composition using gas chromatography technique. The analyzed products contained from 1.2% to 26.9% of fat. The saturated fatty acids (SFA) content ranged from 8.7% to 53.2%, while the monounsaturated fatty acids (MUFA)--from 24.0% to 68.7% of total fatty acids. The polyunsaturated fatty acids (PUFA) percentage accounted for 8,1% to 48,8% and trans isomers--for 0.2% to 6.1% of total fatty acids. The fat and fatty acid contents showed large differences in products depending on their composition and preparation techniques declared by the producer. Most of the analyzed fish and seafood products were characterized by the fat content ranged from 11% to 14% with the high percentage of fatty acids favorable from nutritional point of view, MUFA and PUFA. The composition of fatty acids from pizza and casseroles was less favorable, due to high proportion of SFA and also trans isomers.
