title: Sterol and nutrient excretion in ileostomists on prudent diets.
abstract: Nine ileostomists eating three diets (STAND, RESAT and EXFIB) were investigated in order to quantify the changes in sterol and nutrient excretion when shifting between a standard Western diet and two prudent diets. The RESAT diet had a moderate reduction in fat content to 30 per cent of energy, mainly through a reduction in saturated fat. The EXFIB diet had the same fat modification but in addition the dietary fibre content was raised to 3g/MJ according to current Swedish nutrition recommendations. The RESAT diet resulted in a lowered excretion of fat, but the excretion of nitrogen, energy, cholesterol and bile acids did not change compared with the STAND diet. The EXFIB diet resulted in a higher excretion of fat, nitrogen, energy and cholesterol compared with both the STAND and the RESAT diets (P less than 0.01). Bile acids showed no consistent excretion changes. Thus, a prudent diet, with moderate restricted total and saturated fat content, and a moderate increase in dietary fibre from natural food items, increased the excretion of cholesterol and fat from the small bowel when given to healthy ileostomists. A solely fat-modified prudent diet did not significantly change the pattern of excretion compared with a standard diet.
