Background: With environmental pollution increasing, interest in organic farming and organic foodstuffs has been growing all over the world. Data on organic food consumption by Lithuanian athletes is not yet available. This lack of data determined the aim of this study: to identify the particulars of organic foodstuff consumption among athletes. Methods: In September–November 2012, we polled 158 of the best-performing athletes of the Olympic sports team through direct interviews. An approved questionnaire was used to identify the specifics of organic foodstuff consumption among athletes. Results: The survey results showed that 97% of athletes consume organic foodstuffs, and 80% of athletes highlighted the positive impact of organic food on health. Nevertheless, a slim majority of athletes (51.7%) consume organic foodstuffs seldomly, 2–3 times per week. The range of organic foodstuffs consumed depends on the gender of athletes, and the consumption of some products depends on monthly incomes. Conclusions: Survey results confirm the need for the production and expansion of the variety of organic foodstuffs. In the course of the development of the organic food market, it should be beneficial for manufacturers to target high-performance athletes and physically active people.

Background: Both pleiotropic and ubiquitous, microRNAs (miRNAs) exert control over a wide range of cellular functions. They have been detected in virtually every extracellular fluid in the mammalian body, and many circulate substantial anatomical distances in plasma. Thus, secreted miRNAs are valuable not only as diagnostic tools but also may serve as novel biological effectors that can be transmitted between source and recipient tissue. Design: This review will discuss the possibility of delivering functional miRNAs from exogenously derived dietary sources. We will examine prior research interrogating the existence and relevance of such a mechanism. Findings: Recent findings have reported cross-kingdom transfer of specific plant-derived miRNAs to mammalian tissue following consumption of plant-based foods. These exogenous miRNAs were reported to be active in the recipient organisms, directing changes in gene expression at distant organ sites. In spite of this, subsequent studies have been unable to find evidence of substantial exogenous diet-derived miRNAs in mammalian circulation or tissues, regardless of diet. Conclusion: Further examination of diet-derived miRNA uptake is ongoing, but it does not appear that horizontal delivery of miRNAs via normal dietary intake is a generalizable or frequent process to maintain robust expression of these miRNAs in most higher-order animal organisms.

Nowadays, because of irregular lifestyle, high level of stress dietary supplements (DS) are becoming more popular as a source of needful nutrients among millions of people all over the world. The main purpose of present study was to estimate prevalence of dietary supplement consumption in sport, motivation in DS usage and sources of information. Anonymous self-administered questionnaire was spread among students of medical faculty in the end of their fourth year of study. There were 218 students of the fourth year of the Medical Faculty, of which 60.1% were females and 39.9% were males. Males more often used or had been using dietary supplements than females. The most popular dietary supplement was whey protein. The most common aim among men was to build up muscle mass. It is possible to state conclusions that prevalence of using dietary supplement among students is similar to values reported previously in the literature. Males were definitely more often undertaking physical activity in the gym and that could be the reason why they were definitely more often using specific dietary supplements.

Celem pracy było przedstawienie dawnych oraz współczesnych świątecznych zwyczajów i tradycji żywieniowych w Polsce. Analizy dokonano na podstawie literatury i własnych badań ankietowych. Stwierdzono, że większość respondentów przystępuje do wieczerzy wigilijnej oraz śniadania wielkanocnego, zasiadając w gronie rodzinnym. Wśród najbardziej popularnych dań na wigilię wymieniano: barszcz z uszkami, kapustę z grzybami, pierogi z kapustą i grzybami, makowiec i piernik, smażonego karpia i śledzie w oleju oraz tradycyjny kompot z suszu. Ankietowani znali i rozumieli zwyczaje związane z wieczerzą wigilijną, jednak symbolika wigilijnych potraw była znana i rozumiana przez niewiele osób. Na wielkanocne śniadanie ankietowani spożywali: żurek, białą kiełbasę, ćwikłę, chrzan oraz babę. Znaczny odsetek respondentów znał symbolikę Świąt Wielkanocnych. Znajomość dań regionalnych wśród badanych jest lokalna i nieznana przez wielu respondentów. Podsumowując, żywieniowe tradycje świąteczne są nadal stosowane, za wyjątkiem niektórych dań i napojów, które dawniej stosowano często z powodów braku dostępu do innych surowców lub biedy.

The purpose of the article was to show former and present feeding festival traditions in Poland. The analyses were made on the basis of literature and own surveys. It was found that the majority of respondents acceded to Christmas Eve and Easter breakfast, sitting in the family circle. Among the most popular dishes on the Christmas Eve there were mentioned: beetroot soup with dumplings, cabbage with mushrooms, dumplings filled with sauerkraut and mushrooms, poppy seed cake, gingerbread, fried carp, herring in oil and a traditional compote of dried fruits. Respondents recognized and understood customs associated with Christmas Eve supper, but the symbolism of Christmas Eve dishes was known and understood by very few people. On Easter breakfast respondents ate: sour soup, white sausage, red-beet-and-horseradish sauce, horseradish and an Easter cake. Knowledge of regional dishes among respondents is local and unknown by many interviewees. In conclusion, feeding festival traditions are still observed, except in certain foods and beverages, which formerly were often used for reasons of lack of access to other components or because of poverty. This is the research article.

Climbing is becoming more and more popular. During 2020 Olympic Games this discipline will be competed for the first time. Individualized diet plays a significant role among representatives of all sport disciplines. The aim of this research was to evaluate the correlation between the level of advancement of sport climbers, selected anthropometric indicators and diet composition. The study involved 36 women and 65 men practicing sport climbing who completed the food record and the survey on the most difficult climbing routes completed. Anthropometric measurements were collected. In the group of men statistically significant, positive correlation between the climbing level and the diet content of fiber, vitamin E, potassium, iron, zinc, and copper, was observed. In the group of women, a statistically significant positive correlation between the climbing level and the participation of vitamin C, potassium, magnesium and copper in the diet was observed. There was a positive correlation of protein, vitamin B2, B6, B12, D, phosphorus, magnesium, iron and copper content, and negative correlation between SFA content per 1,000 kcal of the diet and the climbing level of study participants. No statistical correlation was found between anthropometric parameters and advancement level.

The article analyses the conditions of stay and moral attitude of the interned Ukrainian soldiers in Wadowice camp (Poland). It was proved that Ukrainian interned soldiers’ everyday life was connected with a lot of difficulties that were caused by the overpopulation of the camp and quite rough regime of the interns’ stay. Furthermore, indisposed, malevolent and even hostile attitude towards the Ukrainian interned soldiers took place, particularly from the officials at the camp. Consequently, it caused the demoralization of the Ukrainian warriors who did not have national patriotic feelings. These conditions led to the necessity of strengthening the moral spirit of camp dwellers. Cultural and educational departments of the division, camp theatre and other cultural and art centers were responsible for this mission along with the humanitarian aid from the camp affiliate YMCA.

Background: Nutrition influence on cystic fibrosis (CF) patients survival is well documented and dietary therapy is one of basic elements of their treatment. Prolonged survival of CF patients might yet emerge comorbidities, which include bone mineral disease. The aim: The assessment of the dietary pattern and its relationship between bone density in boys and girls with cystic fibrosis. Material and methods: 89 patients aged 10-18 years from 3 Polish CF Centres were included into the study. To obtain a knowledge about quality of diet, a 3-day food record was assessed and percent of recommended for CF patients intake of energy, protein, carbohydrates, fat, vitamin D3, calcium, phosphorus was counted. Bone mineral density (BMD) in lumbar spine (L1-L4) was measured and expressed as a Z-score. To assess nutritional status, anthropometric measurements was evaluated (body weight, height and BMI). Descriptive methods, Mann-Whitney test, T-Student test, Spearman correlation and one-way ANOVA were used for statistical analyses. Results: The patients with cystic fibrosis did not meet specific for CF nutritional guidelines. A deficiency in recommended intake was observed in energy (88%), protein (82%), calcium (78%) and vitamin D3 (71%). The intake of phosphorus was higher than recommended (142%). A nutritional status was significantly reduced, as compared with the reference group (p<0.001). Boys characterized significantly lower body weight (p=0.019) and height (p=0.036) than girls as well as worse caloric (p=0.023) and carbohydrates intake (p=0.005). However, girls had reduced vitamin D3 content in their diet (p<0.001). The bone mineral density in the whole group was reduced and Z-score amounted to -0.95±1.17. Tendency to decreasing of BMD with age was observed. BMI showed important correlation with bone mineral density both in girls (p<0.001) and in boys (p=0.020). Conclusion: CF patients do not follow specific for them dietary recommendations and essential differences were observed between girls and boys. Nutritional status (BMI) showed correlation with bone mineral density in CF patients. Therefore intensive nutritional therapy according to recommendations is needed.

Wprowadzenie: Wpływ żywienia na długość życia chorych z mukowiscydozą (ang. Cystic Fibrosis − CF) jest dobrze udokumentowany, a postępowanie dietetyczne jest jednym z podstawowych elementów leczenia pacjentów z CF. Systematyczne wydłużanie się wieku przeżycia chorych może powodować ujawienie się niedoborów żywieniowych prowadzących do chorób towarzyszących, jakimi są m.in. zaburzenia w gospodarce mineralnej kości. Cel: Celem pracy była ocena sposobu żywienia dziewcząt i chłopców z mukowiscydozą i jego związku z gęstością mineralną kości. Materiał imetody: Do badania włączono 89 pacjentów wwieku 10-18 lat. Wcelu ustalenia jakości diety, oceniono sposób żywienia za pomocą zapisu 3-dniowych jadłospisów, obliczając procent realizacji zapotrzebowania zgodnie z rekomendacjami opracowanymi dla pacjentów z mukowiscydozą. Dotyczyło to pokrycia zapotrzebowania kalorycznego, białka, tłuszczu, węglowodanów, witaminy D3, wapnia i fosforu. Oceniono gęstość mineralną kości (Bone Mineral Density − BMD) w odcinku lędźwiowym (L1-L4). Wynik wyrażono, jako wartość standaryzowaną Z-score. W celu określenia stanu odżywienia dokonano pomiarów antropometrycznych (masa i wysokość ciała oraz BMI). Wykonano następujące obliczenia statystyczne: analizy opisowe, test Manna-Whitneya, test t-Studenta, korelację Spearmana, oraz jednoczynnikową analizę wariancji ANOVA. Wyniki: Badani pacjenci nie spełniali opracowanych dla chorych na mukowiscydozę zaleceń żywieniowych. W diecie zaobserwowano niedobory energii (88% normy), białka (82%), wapnia (78%) oraz witaminy D3 (71%). Wykazano nadmierne spożycie fosforu (142%). Stan odżywienia (parametry antropometryczne) badanej grupy był obniżony i w sposób statystycznie istotny różnił się od grupy referencyjnej (p<0,001). Chłopcy charakteryzowali się znacznie niższą masą ciała (p=0,019) iwysokością (p=0,036) niż dziewczęta, a także niższą kalorycznością diety (p=0,023) oraz zawartością węglowodanów (p=0,005). Dietę dziewcząt cechowała mniejsza zawartość witaminy D3 w diecie (p<0,001) w porównaniu do chłopców. Średnia wartość gęstości mineralnej kości w całej grupie była obniżona i wynosiła -0,95±1,17. Zaobserwowano tendencję do obniżania się BMD wraz z wiekiem. Stan odżywienia wyrażony jako BMI wykazał statystycznie istotną korelację z gęstością mineralną kości, zarówno u dziewcząt (p<0,001), jak i u chłopców (p=0,020). Wnioski: Pacjenci z CF nie przestrzegali opracowanych dla nich zaleceń dietetycznych. Zaobserwowano istotne różnice między dziewczętami i chłopcami. Stan odżywienia (BMI), wykazał korelację z gęstością mineralną kości (BMD), co wymaga intensywnej terapii żywieniowej, zgodnie z opracowanymi rekomendacjami.

The purpose of this study was to evaluate the energy, macronutrient an selected micronutrient intake of second league Rugby Union players and to assess the anthropometric characteristic of this group. Players (n = 44) were divided into forwards (n = 20) and backs (n = 24), who differed significantly in weight (92.6 vs 80.8 kg), BMI (28.6 vs 24.5 kg/m2) and percentage of body fat (22.0 vs 13.3%). The dietary intake was assessed using 3-day dietary recalls. There were no significant differences in dietary intake related to player position. Athletes reported a mean daily energy intake of 3613.4 ±942.6 kcal (carbohydrates 41.4%, protein 17.8%, fats 39.3%). The mean intake of carbohydrates and protein were on a level of 4.8 and 1.9 g/kg of body weight/day, respectively. Although the mean daily intake of minerals and vitamins met recommendations, some players did not reach the requirements, especially for potassium (61.4%) and vitamin C (22.7%). The differences in body compositions of the players suggest differences in the type of training and the specificity of the player’s position. These improper proportions of dietary nutrients within the study group may decrease opportunities to achieve optimum results during matches.

The aim of the investigation was to review experimental articles and patents referring to corn-based nutritional products for sportspeople published in the period 1970–2019. Publications were searched in the ISI Web of Science and Scopus databases, as well as the Google Scholar and Google Patents internet search engines. Factorial combinations of the keywords (“Zea mays” or “maize” or “corn”) and (“athlete” or “sport”) were applied. Most papers and patents were published in the period 2010–2019 by researchers affiliated to the USA and China – the two largest global producers of corn. Altogether, 65 patents and 16 articles were recorded. Inventors patented food supplements based on corn-derived saccharides and proteins. Empirical articles were devoted to the impact of corn-based food products on health of sportspeople, evaluation of the impact of length of consumption on the metabolism and performance of athletes, as well the frequency of use and acceptance of nutritional products based on corn by sportspeople. Despite growing interest in the application of corn constituents in nutritional products for sportspeople, further investigations are strongly desirable.

Adolescence is a period between age 10 and 19. Intensive changes associated with the development of the organism influence the nutritional needs during this period. Young swimmers’ training is characterized by large volume, so their diet can play an important role in their results and future career. The energy intake of a developing athlete should be determined individually based on gender, anthropometric measurement, character, and number of workouts per day. The frequent presence of drowsiness and fatigue during training may indicate insufficient dietary energy supply. Dehydration exceeding 2% of body weight should be prevented. Isotonic drinks should only be consumed during training longer than 75 minutes. Young swimmers should consume adequate amounts of carbohydrates to restore glycogen reserves before another training unit. Carbohydrates with a high glycemic index of 1-1.2 g/kg b.w./h should be delivered during the post-training period. Immediately following training, a meal containing a complete protein should be consumed to accelerate post-exercise recovery. The total protein supply should be at least 1.2 g/kg b.w./h. The minimum intake of fat in the diet of a young swimmer should be 2 g/kg lean b.w. It is recommended to limit products containing large amounts of saturated fatty acids.

Introduction: In the world, the inflammatory bowel disease affects an increasing number of younger and younger patients, and in some of them parenteral nutrition is an alternative to high-risk surgical intervention due to advancement of the disease and malnutrition. Aim: The aim of the study was to assess the results of home parenteral nutrition in patients with severe bowel inflammatory disease, in whom surgical treatment is associated with high risk of complications. Materials and methods: A retrospective analysis was conducted on 46 patients, who received home parenteral nutrition instead of another surgical intervention. The inclusion criteria included home parenteral nutrition and diagnosis of Crohn’s disease or ulcerative colitis. Results: Mean number of complications requiring hospital admission per patient was 1.76, the BMI increased by 4.3 on average [kg/m2]. During parenteral nutrition, the percentage of patients, in whom anti-inflammatory or immunosuppressant drugs were completely discontinued, was 17.4%. In the whole group, at least one immunosuppressive drug was discontinued in onefifth of patients. Mean albumin level increased by 2.4 g/L, lymphocyte count dropped by 474 lymphocytes/mm3, and leukocyte count increased by 747.6/mm3. The patients described their condition as good in 87%, and 7.4% of patients were able to work. Conclusions: Home parenteral nutrition positively affects patient’s general condition by increasing BMI and normalizing biochemical test results. The results indicate the need to consider this method as an alternative to surgical intervention in severe bowel inflammatory disease with high perioperative risk, which could reduce the complication rate.

Vegan and vegetarian diets have become increasingly popular in developed countries. The aim of the research presented here is to review publications referring to the role of plants, algae, bacteria and fungi in the diet of vegan and vegetarian sportsmen published in the period 2000-2021. The review of the literature was based on peer-reviewed original full-text articles and patents using the ISI Web of Science database, as well as the Google Scholar and Google Patents search engines. Factorial combinations of the following keywords were applied: (‘plant’ or ‘alga’ or ‘fungus’ or ‘cyanobacteria’) and (‘athlete’ or ‘sport’) and (‘food’ or ‘nutrition’ or ‘diet’) and (‘vegan’ or ‘vegetarian’). The survey of the literature, carried out according to PRISMA statements, showed that many taxa canbe used in manufacturing products enhancing sport nutrition, athletic performance, mental alertness, physical health, preventing disorders and controlling body weight.Numerous authors found that the ingestion of plant constituents such as caffeine and proteins enhances muscle growth and recovery. Other investigations indicated the occurrence of beneficial effects, as well as imperfections, ofnon-animal diets. The performed investigations documented that acceptance of vegan and vegetarian diets flows from religious and ethical beliefs, as well as the advantages of sustainable eating practices.

Peak cognitive performance is of paramount importance for the sports and competitive activities that depend on a high level of cognitive performance, such as eSports. The popularity of eSports has increased rapidly in recent years and will probably continue to rise in the forthcoming years. Above all, eSports practitioners require higher levels of cognitive abilities and motor skills for optimal performance and may benefit from adequate body composition and proper nutrition, as happens with more traditional athletes. However, there is a noticeable shortage of scientific knowledge in this area, including in nutritional-related aspects. Therefore, the objective of this non-systematic review is to summarize the nutritional strategies that may enhance health, cognitive performance, decrease reaction time and minimize fatigue. This information may be relevant for eSports competitors and set a base for further investigations, which could ultimately lead to the establishment of nutritional recommendations specific for this competitive population.

An integral part of a reasonable, creative, valuable, and positive way of life is also personal responsibility for individual physical and psychical shape and good health: a sound state of body and soul, freedom from disease, bodily conditions, and a wish for health and happiness. In this context we are increasingly aware of the great importance of sport not only as a part of mass culture, but broadly understood, for individual and social health and well-being. Physical activity of people plays an increasingly more important role in scientific interest regarding the way of life of contemporary society, and it is a very important factor in the process of officiating the level of a healthy and active lifestyle, quality of life, and health in general. The indispensable role of physical activity in the course of human life is permanently and scientifically confirmed in the context of the prevention of obesity.The development of a sedentary life style is the result of a socialization process towards physical inactivity developed in youth and continued into adulthood. At the present we face in our cultural settings an apparent tendency: people are more and more individualized, losing the beneficial impacts of community activities, involved in passive way of life, and lacking proper level of physical activities and active sport. The phenomenon of physical activity has also been considered from the perspective of the EURO-PRE-VOB project: accenting built environmental as an aspect of way of life. The Czech Republic is, on the level of mass sport, strongly influenced by the existence of new development of the city structure, including fitness centres, bicycling paths, roller-skating stadiums, beach volleyball playing fields, and golf courses. The national support of sport is, nowadays, divided into the support of top sports, performance sports, and new waves in sports (e.g. sports for everyone - for all), sports for school, which are then on the regional level (and by the various sport organizations) subsidized from other sources and, moreover, not coordinately.

Celem niniejszej pracy jest przedstawienie i ocena zwyczajów żywieniowych populacji 12–17- latków z woj. zachodniopomorskiego i małopolskiego. Materiał i metodyka badań. Przeprowadzono 11 596 autorskich badań ankietowych oceniających model codziennego spożywania posiłków u dzieci i młodzieży w wieku 12–17 lat z województwa zachodniopomorskiego i małopolskiego (w tym 5879 dziewcząt i 5717 chłopców) ze środowiska miejskiego i wiejskiego. Technika badawczą był autorski kwestionariusz ankiety. W badaniach ankietowych uwzględniono: częstość spożywanych posiłków, status zatrudnienia rodziców, dojadanie między posiłkami, miejsce spożywania posiłków oraz zaburzenia w odżywianiu. Otrzymane wyniki poddano analizie statystycznej z wykorzystaniem testu Chi 2 Pearsona, V Cramera, R rang Spearman. Wyniki. W wyniku przeprowadzonych badań stwierdzono, iż niespełna 50% młodzieży spożywa codziennie I posiłek przed wyjściem do szkoły; II posiłek jest spożywany codziennie wyłącznie przez 47,91% badanych, obiad przez 84,90% (miejsce, w którym młodzież najczęściej spożywa obiad to dom rodzinny), a kolacja przez 72,27%. Ulubionymi produktami spożywanymi przez młodzież są: fast-foody, chipsy, słodycze oraz napoje gazowane. Niepokojący jest fakt podjadania między posiłkami (słodycze, chipsy). W populacji 12–17-latków zaobserwowano pierwsze oznaki zaburzeń w odżywianiu się: żarłoczność i poczucie braku kontroli nad jedzeniem (12,53%) oraz jadłowstręt (12,03%). Wnioski. Wśród badanych przeważają nieprawidłowe zachowania żywieniowe. Młodzież nie przywiązuje wagi do ilości spożywanych posiłków w ciągu dnia. Większość badanych spożywa produkty takie jak: fast-foody; chipsy czy słodycze. Znaczna grupa badanych dostrzega niepokojące objawy ze strony organizmu związane z nieprawidłowym odżywianiem.

Introduction. Sensible eating habits are considered – apart from physical activity – to be a major component of a healthy lifestyle. Many research results indicate numerous unhealthy dietary habits in a diet of schoolchildren and adolescents. Aim. This paper is aimed at presenting and assessing eating habits of 12–17-year-olds from Zachodniopomorskie and Małopolskie voivodships in Poland. Material and methods. 11 596 original surveys were carried out. The research was aimed at assessing the model of daily food consumption among children and adolescents aged 12–17 yrs. from West Pomeranian voivodship and Lesser Poland voivodship (including 5879 girls and 5717 boys) from urban and rural environments. The technique used was the original questionnaire. In the research (survey) the following factors were included: frequency of meals, job status of the parents, eating between meals, the place of food consumption and eating disorders. These results were subjected to statistical analysis, using Pearson’s Chi-square test, Cramer’s V and Spearman’s rank correlation coefficient. Results. The results indicated that almost 50% of subjects ate their 1st meal before school; the 2nd meal was consumed by 47.91% of subjects; dinner was eaten by 84.90% (mostly at home); and supper – by 72.27% of subjects. As their favorite food products, the subjects indicated fast-food meals, chips/crisps and fizzy drinks. Alarmingly, subjects tended to eat snacks between meals (sweets, chips/crisps). In the researched population of 12-17-year-olds, initial symptoms of dietary disorders were identified: gluttony and lack of control over eating (12.53%) and revulsion to eating (avoiding food) (12.03%). Conclusions. Unhealthy dietary habits were dominant amongst the subjects. Subjects attached little significance to the number of meals per day. Majority of subjects consumed fast food products, crisps/chips and sweets. A significant proportion of subjects noticed alarming symptoms in their bodies, related to unhealthy dietary habits.
