The medium-term effect of natural or extractive dietary fibres on plasma amino acids and lipids in type 1 diabetics

Abstract We evaluated the effect of a diet rich in natural (NF) or extractive fibres (guar gum) on 12 male IDD (insulin-dependent diabetes) out-patients. The treatment lasted for 2 months. During the first month the patients were on an isocaloric diet containing 30 g of fibres and then they were randomly subdivided into two groups. One group followed an isocaloric diet rich in fibres (70 g/day), the second group an isocaloric diet enriched by guar (9 g of guar added to 30 g of natural fibres/day). Reduced serum levels of HbA 1 c and several amino acids showed that metabolic control significantly improved under each dietary regimen.
