Effect of pectin, guar gum, and wheat fibre on serum-cholesterol.

36 G of wheat fibre, pectin, or guar gum was given over 2-week periods to healthy volunteers taking normal diet. Mean serum-cholesterol levels fell significantly while the volunteers were taking guar and pectin by 36-3 and 29-2 mg, per 100. respectively, but rose slightly after wheat fibre by 6-7, mg per 100., Attention should be focused on fruit and vegetable gels rather than wheat fibre in the search of natural hypocholesterolaemic agents.
