It has been reported that undigestible natural polysaccharides show a hypocholesterolemic effect when fed to rats and chicks fed a hypercholesterolemic diet.In the present paper, the influence of Konjac flour (crude Konjac mannan obtained from the tubers of Amorphophallus Konjac, K. Koch) on lipid metabolism other than cholesterol was compared with two other polysaccharides. Weight gain, levels of triglyceride and phospholipid in serum and liver, and fecal lipids were measured when rats were fed on the low and high fat diet containing 5% of polysaccharides to the rats.1) Serum triglyceride decreased significantly by the addition of Konjac flour in both low and high dietary fat levels. No hypotriglycedemic effect was seen by the addition of citrus pectin and Naalginate. It seems that the hypotriglycedemic phenomenon of the latter two polysaccharides seen in the high fat level is mainly due to the decrease in food intake.2) The increased fecal lipid excretion seen in the case of Konjac flour feeding indicates that Konjac flour inhibits fat absorption in the intestine in any way.3) No change was seen in both hepatic triglyceride and phospholipid levels when Konjac flour was added to the diet.4) The addition of undigestible polysaccharides to a high fat diet suggests the possibility of a more effective weight control.
