Will recommended changes in fat and fibre intake affect cholesterol absorption and sterol excretion? An ileostomy study

Article Abstract:

Dietary modifications with less saturated fat and more dietary fibre will reduce cholesterol absorption in relation to plant sterol excretion in ileostomy patients within 48 hours on controlled diets. There will be a rise in net cholesterol excretion. An isolated cut in saturated fat, compensated with carbohydrates, appears to reduce fractional cholesterol absorption instead of increasing net cholesterol excretion. This research found negative links between fractional (and absolute) cholesterol absorption and plant sterol excretion.

Effects of low-fat milk and fermented low-fat milk on cholesterol absorption and excretion in ileostomy subjects

Article Abstract:

A study on the influence of low-fat milk and fermented low-fat milk on cholesterol absorption and excretion in ileostomy subjects to understand possible serum cholesterol-lowering mechanism of low-fat milk products revealed that absorption of cholesterol by micro organisms could be the reason for the reduced uptake of cholesterol with fermented milk. The reason for the increase in endogenous cholesterol excretion effected by low-fat milk doubtful.

Inulin and oligofructose do not influence the absorption of cholesterol, or the excretion of cholesterol, Ca, Mg, Zn, Fe, or bile acids but increases energy excretion in ileostomy subjects

Article Abstract:

The effects of inulin and oligofructose on cholesterol absorption and excretion of cholesterol, bile acids, energy, nitrogen and minerals in humans were studied in a metabolic kitchen with policlinic visits in Sahlgrenska Hospital, Goteborg, Sweden. Findings indicated that inulin and oligofructose are not digested in the small intestine. They do not affect mineral excretion and therefore hardly mineral absorption. They do not increase fat or nitrogen excretion from the small intestine.
