Resistant starch exerts a lowering effect on plasma urea by enhancing urea N transfer into the large intestine
H Younes, C Demigné, S Behr, C Rémésy - Nutrition Research, 1995 - Elsevier
Fermentable polysaccharides may have interesting effects in the large intestine, on urea N
disposal and N fecal excretion. To further investigate this domain, rats were adapted to diets
containing only digestible starch (DS) or in which a part of the starch was replaced by
resistant starch (RS)(crude potato starch, 250g/Kg), the dietary protein level being either 130
or 260g casein/Kg. Feeding RS led to an hypertrophy of the cecum and a high concentration
of short-chain fatty acids (SCFA) at acidic pH. 25% RS in the diet resulted in an elevated rate …
