Opis:
The Mediterranean diet is characterized by abundance of plant foods, such as vegetables, fruit, bread and cereal products, legumes, nuts and seeds, as well as olive oil, herbs and spices. Moreover, moderate intakes of dairy products, fish, poultry and wine, and low consumption of red meat are recommended. This diet is low in saturated fat (<7% of energy) with total fat within the range of 25-35% of energy. To assess dietary compliance cardiovascular diseases with the recommendations of the Mediterranean diet a variety of indicators are used, of which the most common are: 9-point scale of alternate Mediterranean Diet Score (aMED) and 14-item Questionnaire of Mediterranean diet adherence (MDA). The results of the epidemiological research indicate that the nutrition model based on the assumptions of the Mediterranean diet is a crucial component of primary and secondary prevention of 25-35% of energy.

Opis:
Background. Macrofungal β-glucans are mainly represented by compounds with β-1,3- and β-1,6 glycosidic bonds. They have been shown to have immunomodulatory, anticancer, and antioxidant properties. Although there are many reports on the bioactivity and structure of fungal glucans, studies on the quantitative assessment of these compounds are sparse. Objective. The aim of the study was to determine total β-glucans and 1,3-1,6-β-D-glucan contents in selected species of wild-growing edible Polish mushrooms. Material and methods. Eight species of wild-growing edible mushrooms Boletus pinophilus, Hydnum repandum, Craterellus cornucopioides, Suillus variegatus, Suillus granulatus, Gyroporus cyanescens, Tricholomopsis rutilans, and Auricularia auricula-judae and one species of cultivated mushroom for comparison purposes Agaricus bisporus, were analyzed. Quantitative analysis of 1,3-1,6-β-D-glucans was done using a colorimetric method in accordance with Nitschke et al. Result. Mean total β-glucan content varied from 13.5 g/100 g dry mass in A. bisporus (portobello variety) to 40.9 g/100 g dry mass in T. rutilans. Mean 1,3-1,6-β-D-glucan content in the analyzed fruiting bodies ranged from 3.9 g/100 g dry mass in Agaricus bisporus (cremini) to 16.8 g/100 g dry mass in Auricularia auricula-judae (wood ear). The following mushrooms demonstrated the greatest percentage of 1,3-1,6-β-D-glucan contents in relation to the total β-glucan content: Gyroporus cyanescens (54%), Suillus granulatus (49.8%), Auricularia auricula-judae (47.9%), and Suillus variegatus (40.6%). Conclusions. Among the analyzed species, wild-growing mushrooms had a generally higher average 1,3-1,6-β-Dglucan content compared with cultivated mushrooms such as A. bisporus. The highest average content of these polysaccharides was observed in medicinal mushroom Auricularia auricula-judae. Comparable 1,3-1,6-β-D-glucan content, in relation to this mushroom species, was found in Gyroporus cyanescens, Suillus granulatus and Suillus variegatus, which points to the possibility of the use of these species of mushrooms as medicinal foods.
Wprowadzenie. β-glukany grzybów wielkoowocnikowych występują głównie w postaci związków o wiązaniach β-1,3 oraz β-1,6 glikozydowych. Wykazano, że posiadają one właściwości immunomodulacyjne, przeciwnowotworowe i przeciwutleniające. Pomimo, że istnieje wiele doniesień na temat bioaktywności i struktury glukanów grzybowych, badania dotyczące ilościowej oceny tych związków są rzadkie. Cel. Celem badań była ocena i oznaczenie całkowitej zawartości β-glukanów oraz 1,3-1,6-β-D-glukanów w wybranych jadalnych gatunkach polskich grzybów dziko rosnących. Materiał i metody. Przebadano osiem gatunków grzybów jadalnych dziko rosnących: borowika sosnowego (Boletus pinophilus), kolczaka obłączastego (Hydnum repandum) lejkowca dętego (Craterellus cornucopioides) maślaka pstrego (Suillus variegatus) maślaka ziarnistego (Suillus granulatus) piaskowca modrzaka (Gyroporus cyanescens), rycerzyka czerwonozłotego (Tricholomopsis rutilans) i uszka bzowego (Auricularia auricula-judae) oraz jeden uprawny – pieczarkę dwuzarodnikową (Agaricus bisporus) w celach porównawczych. Ilościową ocenę 1,3-1,6-β-Dglukanów przeprowadzono metodą kolorymetryczną według Nitschke i wsp. Wyniki. Średnia całkowita zawartość β-glukanów wahała się od 13,5 g/100 g suchej masy w pieczarce dwuzarodnikowej (A. bisporus, odmiany portobello) do 40,9 g/100 g suchej masy w rycerzyku czerwonozłotym (T. rutilans). Średnia zawartość 1,3-1,6-β-D-glukanów w analizowanych owocnikach grzybów wynosiła od 3.9 g/100 g s.m. w pieczarce dwuzarodnikowej (A. bisporus odmiany cremini) do 16,8 g /100 g s.m. w uszaku bzowym (Auricularia auricula-judae). Największy udział 1,3-1,6-β-D-glukanów w stosunku do całkowitej zawartości β-glukanów wykazywały następujące gatunki grzybów: piaskowiec modrzak (Gyroporus cyanescens) (54%), maślak ziarnisty (Suillus granulatus) (49,8%), uszak bzowy (Auricularia auricula-judae) (47,9%) oraz maślak pstry (Suillus variegatus) (40,6%). Wnioski. Pośród analizowanych grzybów, gatunki dziko rosnące charakteryzowały się wyższą średnią zawartością 1,3-1,6-β-D-glukanów w porównaniu do uprawnych – pieczarki dwuzarodnikowej (A. bisporus). Najwyższą średnią zawartość tych polisacharydów stwierdzono w owocnikach grzybów leczniczych – uszak bzowy (Auricularia auricula- judae). Porównywalną zawartość 1,3-1,6-β-D-glukanów, w stosunku do uszaka bzowego, stwierdzono w owocnikach piaskowca modrzaka, maślaka ziarnistego oraz maślaka pstrego, co wskazuje na możliwość wykorzystania tych gatunków grzybów jako żywności funkcjonalnej.

Opis:
Purpose: To assess the knowledge of young adults (students of dietetics) of the health benefits of the Mediterranean diet (MedDiet) and the practical application of the principles of this diet. Materials and methods: The study was performed on 97 women, students of dietetics. Research on general information about the respondents and knowledge about the MedDiet was carried out using a questionnaire with 29 questions. To assess the nutritional value of the diet, a 3-day nutritional diary and computer programme Diet 5.0 were used. Adherence to the MedDiet was appraised according to the 9-point scale of aMED (alternate Mediterranean Diet Score). Results: The most students responded that they have high knowledge of the MedDiet, but do not use the MedDiet recommendations in their daily nutrition. Better adherence to MedDiet was significantly associated with the lower waist circumference of the women, higher intake of mono- and polyunsaturated fatty acids, omega3 fatty acids, fiber, vitamin C, folate, vitamin B1, vitamin E and magnesium, and the knowledge of participants of the diet and nutritional value of foods. Conclusions: The adherence to the MedDiet is significantly associated with the participants' knowledge about the diet, the higher nutritional value of the daily diet and lower waist circumference

Opis:
The term metabolic syndrome (MetS) defines the cooccurrence of the related risk factors of metabolic origin that promote the development of cardiovascular diseases with atherosclerotic background and type 2 diabetes. The diagnostic criteria of MetS have undergone modifications for years. Until now no clear definition of MetS has been established. The latest diagnostic criteria of MetS published in 2009 by a group of IDF (International Diabetes Federation) and AHA/NHLBI (American Heart Association/ National Heart, Lung and Blood Institute) experts discern three out of five risk factors: abdominal obesity (taking into consideration population differences), elevated level of triglycerides, reduced HDL cholesterol, hypertension and fasting hyperglycemia. Genetic predispositions and environmental factors, such as lack of physical activity and improper diet are considered to be responsible for MetS development. Therefore, prevention and treatment of MetS should be based first of all on a change in modifiable lifestyle factors, among which proper diet is of essential importance.

Opis:
We studied the effect of differential phosphorus (P) supply on the development of oat seedlings (Avena sativa L. ‘Arab’) as well as localization and activity of acid phosphatases in tissues and root exudates. Plants were grown for 1–3 weeks on nutrient media with inorganic phosphate (+P, control), reduced Pi (0.1 P), phytic acid (PA) as organic P source, and without P addition (−P), in standard conditions or in a split-root culture system. Phosphate starvation reduced shoot growth but increased root elongation and root/shoot ratio, whereas 0.1 P and PA oat plants had similar growth parameters to +P plants. The growth on −P medium significantly decreased Pi content in all tissues, but only a slight Pi decrease was observed in plants grown on 0.1 P and PA media or various split-root system conditions. Pi starvation led to an increase in acid phosphatase (APase) activity in root exudates when compared to +P, 0.1 P, and PA plant samples. APase activity was especially intensive in root cross sections in rhizodermis and around/in vascular tissues of −P plants. For plants grown on 0.1 P medium and on phytic acid, APase activity did not change when compared to the control. Three major isoforms of APases were detected in plant tissues (similar in all studied conditions, with a higher activity of one isoform under Pi deficit). Generally, lowered Pi content (0.1 P) was not stressful to oat plants for up to 3 weeks of culture. Oat plants grew equally well on nutrient media with Pi and on media with phytate, although phytate was considered not available for other plants. The oat plants activated mainly extracellular APases, but also intracellular enzymes, rather via nonlocal signals, to acquire Pi from external/ internal sources under Pi deficiency.

Opis:
Purpose: The present study evaluates antioxidant activity, as well as polyphenol and flavonoid contents in common sprouts, available on the Polish market. The aim of this study was to extend our already published food databases. Materials and methods: Ten seed species from four plant families were analysed. Total polyphenol content of sprout extracts was determined using the Folin-Ciocalteau method. Total flavonoid content was assessed by the aluminium chloride colorimetric method. Total antioxidant status was measured using FRAP and ABTS methods. Results: The FRAP antioxidant potential was 0.60- 2.53 mmol TE (trolox equivalents)/100 g FM (fresh mass), and arranged in descending order it was: white mustard>cress>radish>broccoli>chickpea> sunflower>mung bean>wheat>green lentil>alfalfa), while the ABTS potential was 3.92-16.19 mmol TE/100 g FM (according to decreasing value: white mustard>green lentil>chickpea>sunflower>mung bean>cress> alfalfa>wheat> broccoli> radish). The polyphenol content was 160-774 mg GAE (gallic acid equivalents)/100 g FM, and flavonoid content 15-53 mg QE (quercetin equivalents)/100 g FM. Conclusion: Our results suggest that sprouts in comparison to other foods, despite small weight can be powerful sources of antioxidants. Special attention in human nutrition should be paid to white mustard sprouts as they are excellent source of polyphenol and flavonoid and are characterized by tremendous antioxidant activity.
