Abstract

Namen diplomskega dela je bil predstaviti prehranske lastnosti piva. Pivo je alkoholna pijača, ki vsebuje pomembne prehranske snovi kot so vitamini (predvsem vitamini B kompleksa), minerali (magnezij, kalij in fosfor), nekaj topne prehranske vlaknine in antioksidante. Najpomembnejši antioksidanti v pivu so fenolne spojine, kjer jih 70 % izvira iz ječmenovega slada in 30 % iz hmelja. Sestava antioksidantov v različnih vrstah piva je odvisna predvsem od sestave osnovnih surovin in tehnološkega procesa. Pivo vsebuje tudi pomembne spojine iz hmelja: izohumolone, ki naj bi imeli pozitivno vlogo pri preprečevanju srčno žilnih bolezni, ksantohumol, ki kaže protirakavo delovanje in 8-prenilnaringenin, ki ima najmočnejšo estrogeno aktivnost med fitoestrogeni, kar naj bi vplivalo na zmanjševanje intenzitete simptomov menopavze. V drugem delu naloge smo pregledali literaturo povezano z različnimi učinki alkohola na zdravje ljudi. Nekatere študije kažejo, da ima lahko zmerno uživanje alkohola ugoden vpliv na zdravje ljudi, predvsem pri zaščiti pred srčno žilnimi boleznimi. Zloraba alkohola lahko negativno vpliva na človeško zdravje. Posledice prekomernega uživanja alkohola se manifestirajo kot povečano tveganje za razvoj različnih vrst raka, ciroze jeter, možganske kapi in zasvojenosti z alkoholom.

Secondary title: Nutritional properties of beer
Secondary abstract: The aim of the graduation thesis was to present the nutritional properties of beer. Beer is an alcoholic beverage that contains important nutrients such as vitamins (above all B complex vitamins), minerals (magnesium, potassium in phosphorus), some soluble dietary fiber and antioxidant. The most important antioxidants in beer are the phenolic compounds, where 70 % comes from barley malt and 30 % from hops. The composition of antioxidants in different types of beer depends on composition of raw materials and technological process. Beer also contains important hops compounds: isohumolones, which should perform a positive role in preventing cardiovascular disease, xanthohumol with anti-cancer activity, and 8-prenylnaringenin with the strongest estrogenic activity among phytoestrogens, which is expected to reduce the intensity of menopausal symptoms. In the second part of the thesis we reviewed the literature related to different effects of alcohol on human health. Some studies report that moderate alcohol consumption can have a beneficial effect on human health especially in regard with cardiovascular disease protection. Alcohol abuse can have a negative impact. The consequences of excessive alcohol consumption are increased risk of various cancers, cirrhosis, stroke and alcohol addiction
