Repeated dose oral toxicological evaluation of concentrated barley β-glucan in CD-1 mice including a recovery phase

The cholesterol-lowering effect observed following consumption of oats and barley is attributable to the β-glucan component of the soluble fiber fraction of these cereal grains. β-Glucan has also been reported to modulate immune activity, however, few studies have evaluated the hematological effects of β-glucan following oral exposure. In the...

Evaluation of the toxicity of concentrated barley β-glucan in a 28-day feeding study in Wistar rats

β-Glucans are water-soluble cell-wall polysaccharides consisting of (1→3,1→4)-linked β-D-glucopyranosyl monomers that comprise a considerable proportion of soluble fiber from certain grains including oats and barley. Consumption of foods containing β-glucan or β-glucan-enriched fractions prepared from these grains lower serum cholesterol...

In vitro binding of estrogens by dietary fiber and the in vivo apparent digestibility tested in pigs

Within the framework of experiments related to the association between dietary fiber and breast cancer an in vitro test system was used to study the binding of estrogens to various fibers (e.g. cholestyramin, lignin and cellulose) and fiber sources (e.g. wheat bran, cereals, seeds and legumes). Furthermore, the in vivo apparent digestibility of...
