Lathosterol and other non-cholesterol sterols during treatment of hypercholesterolaemia with beta-glucan-rich oat bran

Article Abstract:

Treatment with beta-glucan-rich oat bran can lead to a reduction in serum cholesterol levels in patients with hypercholesterolaemia. This effect cannot be attributed to an inhibition of endogenous cholesterol synthesis, as oat bran treatment prompts almost no changes in the cholesterol precursors in serum reflecting endogenous cholesterol synthesis. A high serum level of cholestanol is associated with high efficiency of intestinal sterol absorption, and is therefore inversely linked with endogenous cholesterol synthesis and fecal excretion of neutral sterols.

Mode of action of oat bran in the gastrointestinal tract

Article Abstract:

A study of the effect of oat brans on digestion and absorption in the small and large intestines finds that the starch digestibility in the small intestine is unaffected by oat bran, and the digestibility in the large intestine increases with resisting digestion. In oats, degradation of dietary fiber polysaccharide, beta-glucan take place in the distal part of the small intestine. This beta-glucan generates a large amount of butyrate with oat bran.

A comparison of commercial fibre sources: barley, bran, corn bran, orange fibre and sugar beet fibre

Article Abstract:

Commercially available fibre sources include barley bran, corn bran, orange fibre and sugar beet fibre. Seasonal changes, batch-to-batch variations, and methodological variations influence the variations in total dietary fibre content. The importance of chemical analysis in quality control of characterization of fibre sources is discussed.
