Abstract: An object of the present invention is to provide an agent for suppressing elevation of blood alcohol concentration and a method for suppressing elevation of blood alcohol concentration, the agent and the method enabling prevention of an intoxication state upon drinking and further prevention of hepatic dysfunctions due to drinking such as fatty liver. Provided are an agent for suppressing elevation of blood alcohol concentration, comprising a dextrin as an active ingredient, and a method for suppressing elevation of blood alcohol concentration, comprising, when alcohol is ingested, ingesting 0.5 parts by mass or more of a digestible dextrin and/or an indigestible dextrin relative to 1 part by mass of the ingested alcohol.

Abstract: Provided is a novel IgA secretion promoter useful as a mucosal immunity stimulation agent and a method of promoting IgA secretion in a body of animal to stimulate mucosal immunity. A significant action of promoting IgA secretion was observed in oral administration of indigestible dextrin.

Abstract: The present invention relates to a process for improving mineral absorption in a subject comprising administering to the subject a mineral-absorption promoter comprising indigestible dextrin or a derivative thereof as an effective component together with a mineral-containing diet or supplement.

Abstract: The present invention relates to a mineral-absorption promoter comprising hardly digestible dextrin or a derivative thereof, as well as food and feed containing the same. The mineral-absorption promoter of the invention can easily be applied to food, has resistance to digestive enzymes secreted by mammals and a function of promoting the absorption of minerals through intestinal or digestive tracts.
