Rat jejunal disaccharidases were measured after feeding high fat fibre-free, high fat pectin, high fat cellulose, high fat galactomannan and high fat tannin diets for 27 weeks. Compared with the high fat fibre-free diet, pectin lowered both lactase and sucrase levels (p < 0.025). Galactomannan and tannin lowered only the lactase level (p < 0.05), while cellulose had no significant effect on disaccharidase levels. These data suggest that dietary fibre components have individual and specific effects on jejunal disaccharidase levels, in the presence of a high fat diet.
