Nowadays, a great attention is paid to the biological activity of plant polyphenols and their potential importance for the human health. Therefore knowledge regarding the dietary intake of polyphenols and their particular subclasses has gained interest. In this report, the results of a pilot study evaluating the average polyphenol content in the Czech diet have been presented. Knowledge of the average intake of plant polyphenols is an important contribution to the evaluation of the dietary pattern from the aspect of its health impact. An annual average consumption of the main foods of plant origin (a total of 80 commodities) was estimated, using data from the Czech annual statistical report, in the entire Czech population in 2013. These values (kg/y) were multiplied with the contents of plant polyphenols in the same items as presented in the in the database Phenol Explorer. The average intake of plant polyphenols was 426 mg/d. The prevailing polyphenols were chlorogenic acid, 82 mg/d (most important sources were potatoes, coffee, plums), followed by apigeninfl avone, 79 mg/d (wheat), heneicosylresorcinol, 38 mg/d (wheat), ferrulic acid, 17 mg/d (wheat) and anthocyanin malvidin, 13 mg/d (red wine). These values are below the intake of polyphenols in the most EU countries. These differences reflect – interalia – the fact that beer having low content of polyphenols is a dominant commodity in Czech dietary pattern while fruit and vegetables as well as teas and coffee consumption is relatively low.
Background. Polycystic ovary syndrome (PCOS) manifests itself with various symptoms, therefore it interests representatives of many medical specializations: general practitioners, gynecologists, endocrinologists, dermatologists, cardiologists and those who deal with metabolic disorders, such as dieticians. Objective. The aim of this study was perform the qualitative assessment of components of diets of women with PCOS as one of the major factor contributing to the disease. Material and Methods. The study was performed on 54 women of childbearing age with PCOS diagnosed according to on the Rotterdam criteria. Qualitative assessment of the diets on the basis of 216 menus was performed based on the analysis of 3-day food diaries and food records taken from the last 24-hour dietary interview. Diets quality assessment was made using three types of point tests: Szewczyński’s Diets’ classification (SDC), Bielińska’s Test with Kulesza’s modification (BTK), Healthy Diet Indicator (HDI). Results. Average waist-hip ratio (WHR) and body mass index (BMI) was above the standard 0.91± 0.08 and 29.16 ± 5.8 kg/m2. Qualitative analysis performed with point tests SDC, BT-K and HDI revealed that the majority of the diets were composed inappropriately, containing many mistakes. Statistically significant correlations (Pearson’s) were determined between HDI test and the body weight and BMI. When analyzing the type of the meals also the correlations (Spearman’s) between BMI and BMI category in BT-K test. Conclusions. Mistakes in diets of women with PCOS are the cause of metabolic disorders related to improper function of ovaries. Native test BT-K seems to be a better method then test SDC and probably HDI of assessing diet in women with PCOS from Poland.
Using the method of food frequency questionnaire, energy intake and that of selected nutrients was studied in two groups of children with coeliac disease kept on gluten-free diet or on traditional diet containing gluten. The recommended dietary allowances for energy, basic nutrients, phosphorus, magnesium, potassium, vitamins A, E, C and B-vitamins (thiamin, riboflavin and niacin) were generally sufficiently covered. In both groups of children the intake of energy and fat was particularly high, the intake of cholesterol and sodium was also too high. The mean intake of calcium, iron, zinc and copper was below the recommended values. No statistically significant differences were found between these groups in the intake of energy and nutrients. In about one-fourth of children with coeliac disease on gluten-free diet or on the traditional one the intake of protein, magnesium, vitamin E, vitamin C, thiamin and riboflavin was below the recommended level, and at least half these children had calcium, iron, zinc, copper and niacin intake below the recommended values.
Background. Running causes that people become more and more willing to engage in physical activity. It is an valid exercise that significantly decreases postprandial glycemia. The higher the training load, the more important it is to complement nutrients necessary for organism regeneration. Modern food industry provides many products that can help in resynthesis of muscle glycogen. The study presents a mutual correlation between consuming high-carbohydrate products with and without having exercise afterwards and the shape of the blood glucose curve. Material and methods. Nine healthy and hard training male adult athletes participated in 2-part (P1 and P2) research: P1 with, and P2 without run. After the run, the athletes had a specified meal, after which capillary blood glucose test was taken for P1 before the run and for both groups 2-3 min, at 30, 60, 90 and 120 min after the meal. Results. The comparison of the area under the curve (AUC ) at rest and after 1 hr run showed statistically significant variations after every 30 minutes period and in the overall AUC . The smallest AUC occurred after consuming chips and spinach pasta and the highest after potatoes, white and brown rice. Conclusions. Physical activity does not change the way glucose is released into the blood, but it lowers postprandial glycemia, especially after 30-90 minutes after training completion. This study indicates that consuming potatoes and rice leads to the highest rate of muscle glucose uptake and further faster glycogen re-synthesis after the run. Accordingly, these products can be a good choice for athletes having a short break between training bouts.
Background. Irritable Bowel Syndrome (IBS) is one of the most frequent digestive system diseases, of various medical signs. It is assumed that proper life style, including appropriate, rational diet is a factor helpful for treating such a disorder. Objective. The purpose of this paper was to assess the selected dietary habits, and to evaluate the nutritional value of daily food rations for patients with a mixed type of Irritable Bowel Syndrome. Material and Methods. The questionnaire survey involved a group of 32 women suffering from a mixed type of Irritable Bowel Syndrome (The Rome III Diagnostic Criteria were used to diagnose the disease). The control group was comprised of 32 healthy women. The methods used to assess the diet were divided into quantitative and qualitative ones. Results. The most frequent dietary mistakes among patients with IBS were associated with snacking sweets (83.0% of the subjects) and fruit (17.0% of the subjects) between the meals. A higher intake of sucrose was found amongst women with IBS, than in the case of the control group (p=0.0169). The analysis of the results demonstrated a significantly higher intake of water (derived from drinks and foods) amongst patients with IBS, than in the case of women of the control group (p=0.0267). An insufficient intake of plant proteins and polyunsaturated fatty acids was recorded in both groups. The supply of protein in general, animal protein, fat in general, saturated fatty acids and sodium, exceeded the recommended norm, both amongst women with IBS and women of the control group. Conclusions. The obtained examination results showed that there are significant dietary improprieties in the diet of women suffering from IBS. In order to eliminate these mistakes in the future, it seems justified to extend the knowledge on rational nutrition amongst patients with IBS.

Background. Nutrition plays an important role in the elderly stage of life. A proper proportion of the individual nutritional ingredients in a diet may positively impact the ageing body. This positive influence consists in slowing down the undesired and unfavourable physiological alterations leading inevitably to the general weakness of the body. Objective. The aim of the paper was to perform a qualitative analysis with the Starzyńska scoring system for diets, the daily food rations (DFR), among students of the University of the Third Age at the Koszalin University of Technology (Poland). Material and methods. The studied materials consisted of the 7-day current records made by 79 students (16 males and 63 females) of the University of the Third Age at the Koszalin University of Technology and the measurements of body weight, height and waistline. The records were qualitatively evaluated with Starzyńska’s test. Results. It was found that approximately half of the students were overweight or obese. The majority consumed the recommended number of meals. About 44% of the students consumed animal protein with all meals. Milk and cheese were ingested daily with at least two meals by approximately 11% of the students. Fruit and vegetables are eaten on a daily basis by about 60% of the students. Almost 40% ate wholegrain bread, groats, and dried legumes. The statistical analysis of the means for the points of individual indicators did not reveal any statistically significant difference between women and men (p>0.05). Conclusions. Approximately ¾ of the evaluated diets were inaccurately formulated and required radical modification. The low frequency of animal protein, milk and cheese, wholegrain bread, groats and dried legume consumption may result in deficiencies in certain nutrients. Nutritional education is recommended, focusing on the correct way to formulate meals. The recorded level of overweight and obesity in the students indicates a need for a quantitative assessment of consumption considering, among others, the energy input in their diets.

Meat quality of fattening pigs fed yellow lupin-based diets. The 30 crossbred pigs [(Landrace x Yorkshire) x Duroc] were fattened in 3. phase fattening period. In their nutrition as a source of protein was used soybean meal (Group C) or soybean meal and seeds of yellow lupine in the amount of 7.5% (Group E1) and 15% (Group E2). After achieving body weight of about 117.5 kg animals were slaughtered. The samples of Musculus longissimus lumborum collected from all slaughtered pigs. Significant differences were found in drip loss percentage between groups C and E1 (P ≤0.05). As regards the fatty acids, there were lower proportions of C18:2 in group E1 vs C (P ≤0.05) and of C18:2 and C20:4 in group E2 vs C (P ≤0.01). Differences in PUFA percentage, PUFA/SFA ratio, and proportion of n-6 fatty acids were significant, with lower values of the traits in group E1 vs C (P ≤0.05) and in group E2 vs C (P ≤0.01), which shows that the dietetic value of pork has slightly deteriorated. The chemical composition and the physical parameters of the meat samples were normal and at a similar level in all the groups.
The aim of this study was to determine the impact of diet on the fatty acids profile in European catfish meat. The study material was comprised of fish reared in earthen ponds and fed with natural food and fish fed intensively with artificial feed in a recirculating system. The quality of the fatty acids profile in the meat of the two groups differed. A total of twenty-eight acids were identified in the catfish reared on natural food. The fish fed artificial feed contained an additional two acids – 22:1n-9 and 16:4, which were also detected in the artificial feed. The combined total share of saturated acids, MUFA, and PUFA was similar. However, the share of most of the fatty acids from these groups, including total PUFA n-6 and n-3 and HUFA n-3 and n-6, differed significantly. The catfish fed on artificial feed contained more n-3 acids and fewer n-6 acids. Above all, this was caused by the greater share of 20:5n-3 (eicosapentaenoic, EPA), 22:6n-3 (docosahexaenoic, DHA), and 20:3n-3 and 20:4n-3 acids and the lesser share of 18:3n-3 (a-linolenic, ALA) acid. The meat of the fish from this group also contained fewer 20:4n-6 (arachidonic, AA), 20:3n-6, and 22:5n-6 acids. Additionally, the n-3/n-6 acid ratio was significantly different at 2.31 (pond culture) and 3.93 (intensive culture on artificial feed).
