Abstract

Rad donosi pregled o najnovijim dostignućima potencijalne promocije zdravlja β-glukana iz zobi. Ovo topljivo prehrambeno vlakno ima sposobnost snižavanja postprandijalne razine glukoze u krvi te inzulinskog odgovora, snižava ukupni kolesterol u krvi i lipoprotein male gustoće (LDL), poboljšava nivo lipoproteina visoke gustoće (HDL), ukupnih lipida u krvi te pomaže u održavanju tjelesne mase. Prema tome, β-glukan iz zobi je koristan u prevenciji, liječenju i kontroli dijabetesa i kardiovaskularnih bolesti. Nadalje, β-glukan iz zobi stimulira imunološke funkcije tako što aktivira monocite/makrofage i povećava količinu imunoglobulina, NK stanica, T-stanice ubojice i druge, što poboljšava otpornost na pojavu karcinoma, infektivnih i parazitskih bolesti. Također, ima blagotvorno djelovanje na kožu. Sve navedene zdravstvene koristi β-glukana iz zobi mogu se objasniti s obzirom na njegove fizikalne osobine (kao što su viskoznost, molekulska masa) koje utječu na metodu ekstrakcije i ponašanje u gastrointestinalnom traktu.

Abstract (english)

This work presents an overview of the recent advances into the health promoting potentials of oat β-glucan. This soluble oat fiber is able to attenuate blood postprandial glycemic and insulinemic responses, to lower blood total cholesterol and low-density lipoprotein (LDL) cholesterol, and to improve high-density lipoprotein (HDL) cholesterol, blood lipid profiles and is able to maintain body weight. Thus, oat β-glucan intake is beneficial in the prevention, treatment, and control of diabetes and cardiovascular diseases. In addition, oat β-glucan can stimulate immune functions by activating monocytes/macrophages and increasing the amounts of immunoglobulin, NK cells, killer T-cells, and so on, which will improve resistance to cancer and infectious and parasitic diseases. Also, it has a beneficial effect on skin. All these health benefits of oat β-glucan may be explained by its physicochemical properties (such as viscosity, molecular weight) which can be affected by extraction methods and its behavior in gastrointestinal tract.
