Description

<p>　Soluble dietary fiber (SDF) from the red alga Pyropia yezoensis (nori) is expected to alleviate lifestyle-related diseases. In this study, we investigated the effects of SDF from nori on the lipid profile of Wistar rats determined by the oral lipid tolerance test. After 60 min of administration of a lipid bolus, serum triglyceride was significantly lower in the SDF group than in the control group. Also, the administration of gum arabic with lipid inhibited lipid absorption. These results suggest that SDF from nori and gum arabic may alleviate hyperlipidemia. We suggest that the inhibition of lipid absorption is due to emulsion stability and inhibition of lipase.</p>
