Nutritional status and dietary habits of patients with inflammatory bowel disease in comparison with patients with irritable bowel sindrom

Upalne bolesti crijeva (IBD) su heterogena skupina bolesti (Crohnova bolest, ulcerozni kolitis), a očituju se kroničnom aktivacijom imunosnog odgovora i upalom na različitim mjestima uzduž probavnog sustava. Sindrom iritabilnog crijeva (IBS) je kronični funkcionalni poremećaj probavnog sustava kojeg karakterizira bol u trbušnoj šupljini i poremećaj funkcije crijeva, ali bez strukturnih ili biokemijskih abnormalnosti. Cilj ovoga rada je bio procijeniti prehrambene navike, nutritivni status i kvalitetu života obaju navedenih skupina, što je provedeno antropometrijskim, dijetetičkim i laboratorijskim ispitivanjima. U istraživanje su uključeni ambulantni pacijenti Kliničkog bolničkog centra Zagreb – Rebro, pri čemu je 28 pacijenata dobi od 19 do 61 godine činilo eksperimentalnu skupinu s dijagnozom IBD-a, dok su preostala 34 pacijenta dobi od 21 do 55 godina s dijagnozom IBS-a predstavljala kontrolnu skupinu. Antropometrija je uključivala mjerenje tjelesne visine i mase te izračun indeksa tjelesne mase, a dijetetičke metode NRS2002 i IBDQ obrasce te dnevnik prehrane. Laboratorijska mjerenja su uključivala praćenje statusa vitamina (D, B12, folna kiselina), željeza, feritina, kalprotektina, CRP-a te fibrinogena. Iako obje skupine u prosjeku imaju normalnu tjelesnu masu i nizak nutritivni rizik, pokazalo se kako IBD skupina ima prosječno veće vrijednosti ITM – a, a prema IBDQ obrascu, i veću kvalitetu života od IBS skupine. U IBD skupini zabilježen je nedostatan unos vitamina A, D, E, magnezija i cinka, dok IBS skupina unosi nedovoljno vitamina A, C, D, E, K, cinka, magnezija te željeza. Laboratorijskim se ispitivanjima utvrdilo kako IBD skupina ima značajno više vrijednosti kalprotektina, fibrinogena i folne kiseline, a značajno niže vrijednosti željeza, što ukazuje na upalni karakter bolesti i veću učestalost problema apsorpcije koji se susreću kod IBD-a.Inflammatory bowel disease (IBD) is a heteregenous group of disease (Crohn disease, ulcerative colitis) characterized by chronic activation of immune system and inflammation along gastrointestinal tract. Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder specific by abdominal pain and gut function disorder, without any structural or biochemical abnormalities. The aim of this study was to evaluate dietary habits, nutritional status and quality of life for both mentioned groups, what was performed with antropometric and dietetic methods and laboratory testing. The research included ambulant patients from University Hospital Centre Zagreb – Rebro. While 28 patients at age range from 19 to 61 with an IBD diagnose made an experimental group, the remaining 34 patient at age range from 21 to 55 with an IBS diagnose were representing control group. Antropometry included measuring of height, body mass, calculation of body mass index and dietetic methods consisting of dietary diary, NRS2002 and IBDQ forms. Laboratory measurements included vitamins (D, B12, folic acid), iron, ferritin, calprotectin, CRP and fibrinogen status. Both groups have normal body mass and have low risk of malnutrition, however, IBD group has higher BMI values and, according to IBDQ form, better quality of life. IBD group also reports vitamins A, D, E, magnesium and zinc deficiency, while IBS group being deficient in vitamins A, C, D, E, K, zinc, magnesium and iron. Laboratory testing found significantly higher levels of calprotectin, fibrinogen, folic acid and significantly lower levels of iron in IBD group. This indicates that character of disease is inflammatory and also explains frequent problems with apsorption in patients with IBD

Factors affecting consumers´ preferences for products from aquaculture

Fish is an essential component of a balanced and healthy diet and the present demand for fish cannot be sustained by capture fisheries. Consequently, aquaculture is currently the fastest growing food production industry in the world, contributing to more than half of the global fish production intended for human consumption. Although the image of aquaculture is not necessarily negative per se, consumers around the world still have a greater preference for wild fish. Therefore, the aim of this review is to critically evaluate some of the factors which may affect consumer preferences: socio-demographic characteristics of consumers, quality and safety perception of products from aquaculture, price of aquaculture products and socio-economic aspects of aquaculture, and concerns about the negative impact of aquaculture on the environment and about the sustainability of the production method. A literature review confirmed that age is the most influential sociodemographic variable. Being younger, female or having higher income and a higher education level can result in greater preference for aquaculture products. The image of farmed fish suffers from a perception of lower quality in terms of taste, health and nutritional value and, in some cases, even from low safety perceptions. On the other hand, farmed fish is believed to have lower prices and greater availability. Additionally, economic benefits are one of the main advantages of aquaculture. Mixed results emerge, however, with regard to the environmental impact of aquaculture, but sustainable production may compensate for possible environmental concerns and drive preference for farmed fish. Depending on how consumers weigh up the advantages and disadvantages of both aquaculture and its products, this will result in a preference for wild or farmed fish

Carob and poppy as sources of functional ingredients

Rogač (Ceratonia siliqua L.) je drvo mediteranskog područja, čiji se plod (mahuna) tradicionalno upotrebljava u kulinarstvu, a u današnje vrijeme posebno kao zamjena za kakaov prah. Iznimno je bogat polisaharidima, kao i polifenolima (posebice taninima), a zahvaljujući njihovim antioksidacijskim svojstvima, sve veću primjenu ima i u medicinske svrhe. Mak (Papaver somniferum L.) je začinska biljka mediteranskog područja, koja se najčešće koristi u konditorskoj i farmaceutskoj industriji. Bogat je alkaloidima (morfin, papaverin, noskapin, tebain i dr.), no, s druge strane, bioaktivni sastav maka još uvijek nije dovoljno istražen. Stoga, cilj ovog rada bio je odrediti bioaktivni sastav (ukupni polifenoli i flavonoidi, flavan-3-oli, hidroksicimentne kiseline, proantocijanidini, ukupni tanini, flavoni i flavonoli), antioksidacijski kapacitet te udjel topljivih polisaharida rogača i maka. Udjel polifenolnih spojeva, kao i antioksidacijski kapacitet ispitan reakcijama s radikalima 2,2′-azino-bis(3-etilbenzotiazolin-6-sulfonskom kiselinom) (ABTS) i 2,2′-difenil-1-pikrilhidrazilom (DPPH) te željezo(III)-tripiridiltriazinom (FRAP), određen je spektrofotometrijskim metodama. Definiran je i senzorski profil napitaka rogača i maka pripremljenih s vodom i mlijekom te je provedena senzorska analiza istih. Prema dobivenim rezultatima, u odnosu na mak, rogač se istaknuo kao bolji izvor bioaktivnih spojeva, izraženijih antioksidacijskih svojstava, kao i višeg udjela topljivih polisaharida. Udjel ukupnih polifenola u rogaču iznosio je 5,78±0,08 mg EGK/g, dok je u maku udjel istih iznosio 2,16±0,00 mg EGK/g. Napitci rogača su senzorski bolje ocijenjeni, posebice napitak s vodom, dok je kod maka prihvatljiviji bio napitak s mlijekom.Carob (Ceratonia siliqua L.) is a Mediterranean tree whose fruit (pod) is traditionally used in culinary, and nowdays especially as a cocoa substitute. It is very rich in polysaccharides, as well as in polyphenols (especially tannins), and due to their antioxidant properties, his usage in medicinal purposes is increasing. Poppy (Papaver somniferum L.) is a spicy herb of Mediterranean area, mostly used in confectionery and pharmeceutical industry. It is abundant in alkaloids (morphin, papaverin, noscapin, thebain etc.), but, on the other side, bioactive content of poppy has not been enough investigated. Therefore, the aim of this study was to define bioactive content (total polyphenols and flavonoids, flavan-3-ols, hydroxycinnamic acids, proanthocyanidins, total tannins, flavones and flavonols), antioxidant capacity and soluble polysaccharides content of carob and poppy. Polyphenolic compounds, and antioxidant capacity examined by reactions with 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals and ferric tripyridyltriazine complex (FRAP), were determined spectrophotometrically. As well, sensory profile of carob and poppy brews prepared with water and milk was defined, and their sensory analysis was performed. According to the obtained results, in comparison to poppy, carob was highlighted as a better source of bioactive compounds, with stronger antioxidant properties, and higher content of soluble polysaccharides. Total polyphenol content in carob was amounted to 5,78±0,08 mg GAE/g, while in poppy their content was 2,16±0,00 mg GAE/g. Carob brews, especially the one prepared with water, were sensory evaluated with higher scores, while among poppy brews more acceptable was brew prepared with milk
