Ксило-Олигозахариди (XOS)
Ксило-Олигозахаридите (XOS) са пребиотични фибри, намиращи се в естествени източници, но в недостатъчна концентрация за всички пребиотични ефекти [1][2]. НАТВИ Хелткеър използва Ксило-Олигозахариди (XOS) в своите продукти, произведени чрез ензимен биосинтез на ксилан от царевичен кочан, позволявайки максималната концентрация от най-малко 95%.
IMO са въглехидрати, които са класифицирани като несмилаеми Олигозахариди (NDO) [3]. NDOs представляват една от най-важните съставки в храните, осигурявайки не само важна хранителна стойност и органолептично качество, но и функционални свойства, полезни за човешкото здраве и благополучие [4].
Ксило-Олигозахаридите (XOS) не се усвояват от човешките ензими, а се ферментират от пробиотиците в дебелото черво, като селективно поддържат растежа предимно на Lactobacillus и Bifidobacterium [5][37][38]. Допълнителни положителни ефекти са увеличаване количеството на полезните бактерии като Faecalibacterium prausnitzii и Akkermansia muciniphila, както и потискане растежа на патогенните Helicobacter pylori, Clostridium difficile, Clostridium perfringens, Escherichia coli, Listeria, Bacteroides, Campylobacter и Actinomyces [38][39][40][41][42][43][44]. Ферментацията на XOS води до множество метаболити, от които основната група са късоверижните мастни киселини (SCFA) и най-вече повишено производство на ацетат, пропионат и бутират [48]. SCFAs играят решаваща роля за човешкото здраве [7].
Ползи от XOS:
Модулиране на стомашно-чревната микробиота, стимулиране на пробиотичния растеж [8][38]
Намалено чревно рН [9][38]
Увеличаване нивата на SCFA [9]
Инхибиране на патогени в чревната микрофлора [10] [11] [12] [13][38]
Намаляване на кръвната глюкоза, серумните липиди и холестерола [49]
Подобрено усвояване на минерали и витамини [10] [11][14] [49]
Подобряване на имунната функция и имунологичните свойства, с имуномодулиращ ефект [38][45]
Антитуморни ефекти [38]
Антиоксидантни ефекти [38]
Подобрява функцията на червата [45]
Противовъзпалително и антиалергично действие [45]
Ефект при възстановяването и заздравяването на чревната лигавица, и подобряване на симптомите на дебелото черво при улцерозен колит (UC), и възпалителните заболявания на червата (IBD) [47]
Редуцира натрупването на мазнини в черния дроб, адипогенеза и липогенеза на мезентериалната мастна тъкан, и метаболитна дисрегулация [50]
Повлияване при наднормено тегло чрез намаляване на генната експресия на маркери за адипогенеза и синтез на мазнини, намалява висцералните мазнини [50]
