 Dietary fibre is suspected to effect the faecal concentration and excretion of bile acids by binding the bile acids and by increasing the faecal mass. Bile acids, especially the secondary bile acids, are potential risk factors for colorectal cancer. A high bile acid-binding ability of fibre could lead to lower blood cholesterol concentrations by interrupting the enterohepatic circulation. There is evidence that the consumption of lupin kernel fibre, containing both soluble and insoluble fibre fractions, may beneficially modify bowel health.
