Different soluble dietary fibers known to alter cholesterol metabolism were fed to golden Syrian hamsters, and their specific impact on lipoproteins, biliary bile acid profile, and fecal sterol excretion was evaluated. Semipurified diets containing 20% fat; 0.12% cholesterol; and 8% of psyllium (PSY); high (hePE) and low (lePE) esterified pectin; or high (hvGG) and low (lvGG) viscous guar gum were fed for 5 wk. Compared to control, PSY caused a significant reduction in plasma cholesterol (2.9±0… 
Increased fecal bile acid excretion and changes in the circulating bile acid pool are involved in the hypocholesterolemic and gallstone-preventive actions of psyllium in hamsters.
TLDR
Increased fecal bile acid excretion and alterations of the circulating bileacid pool by removal of dihydroxy bile acids appear to be main modulators of the hypocholesterolemic action of PSY by leading to an up-regulation of hepatic bile Acid synthesis.
Effects of different cereal fibers on cholesterol and bile acid metabolism in the Syrian golden hamster
ABSTRACT This study examined the effects of various cereal fibers and various amounts of β-glucan on cholesterol and bile acid metabolism. Hamsters were fed semisynthetic diets containing 0.12%
Hypocholesterolemic Effect of Dietary Psyllium in Female Rats
TLDR
The feeding of the cholesterol-enriched semipurified diets resulted in a progressive increase in plasma cholesterol levels in both groups during the 8 weeks of the experiment, and differences in total plasma cholesterol concentrations were predominantly reflected in differences in VLDL cholesterol.
Cholesterol-lowering effect of non-viscous soluble dietary fiber Nutriose6 in moderately hypercholesterolemic hamsters.
TLDR
Results suggest the use of NUTRIOSE6 as a new dietary cholesterol-lowering agent that should be tested in humans as treatment and evenly prevention of mild hypercholesterolemia.
Psyllium and fat in diets differentially affect the activities and expressions of colonic sphingomyelinases and caspase in mice.
TLDR
Colic sphingomyelin metabolism and apoptosis were affected by psyllium and fat in an opposite manner, and the results may have implications for colorectal tumourigenesis and inflammation.
Hepatic gene expression related to lower plasma cholesterol in hamsters fed high-fat diets supplemented with blueberry peels and peel extract.
TLDR
Analysis of plasma lipid profiles, genes related to cholesterol and bile acid metabolism, and inflammation in liver as well as adipose tissue from Syrian Golden hamsters fed high-fat diets supplemented with blueberry pomace byproducts suggest that hepatic modulation of bile Acid and cholesterol synthesis primarily contributes to the cholesterol-lowering effect of BB pomACE byproducts.
Examining the Effects of Diet Composition, Soluble Fiber, and Species on Total Fecal Excretion of Bile Acids: A Meta-Analysis
TLDR
The findings from this meta-analysis indicate that not only soluble fiber, but also increasing levels of dietary fat and protein may result in greater fecal excretion of BA, potentially altering taurine and/or glycine metabolism and affecting the need for diet delivery of these AA.
In vitro bile acid binding and short-chain fatty acid profile of flax fiber and ethanol co-products.
TLDR
In vitro fermentation and bile acid binding models were used to investigate the metabolic effects of lignaMax and oil-depleted flaxseed fractions and WIF/RIF (co-products from ethanol production) could be potential sources of dietary fiber in human nutrition.

The cholesterol-lowering effect of guar gum is not the result of a simple diversion of bile acids toward fecal excretion
TLDR
Even if PHGG does alter some parameters of the enterohepatic cycle of cholesterol and bile acids, its effects are not sufficient to elicit a significant cholesterol-lowering effect.
Distinct mechanisms of plasma LDL lowering by dietary fiber in the guinea pig: specific effects of pectin, guar gum, and psyllium.
TLDR
The results indicate that the distinctive reductions in hepatic cholesterol induced by PE, GG, and PSY associated with plasma cholesterol lowering result from different mechanisms specific to each fiber and that the levels of dietary cholesterol contribute to the different metabolic responses.
Cholesterol 7 alpha-hydroxylase activity is increased by dietary modification with psyllium hydrocolloid, pectin, cholesterol and cholestyramine in rats.
TLDR
Data support the hypothesis that the hypocholesterolemic effect of soluble fibers is modulated through increased synthesis and therefore pool size of bile acids.
Citrus pectin and cholesterol interact to regulate hepatic cholesterol homeostasis and lipoprotein metabolism: a dose-response study in guinea pigs.
TLDR
The most significant effects of CP on hepaticolesterol, enzymes of hepatic cholesterol homeostasis, and the apolipoprotein B/E receptor were in animals fed the HC diets, which partially explain the reduced plasma LDL of guinea pigs fed large amounts of CP.
Psyllium reduces plasma LDL in guinea pigs by altering hepatic cholesterol homeostasis.
TLDR
Results indicate that psyllium generates a negative cholesterol balance across the liver which results in induction of cholesterol 7 alpha-hydroxylase and HMG-CoA reductase and suppression of ACAT activities, upregulation of apoB/E receptors, and secretion of smaller VLDL particles, metabolic alterations that contribute to a lowering of plasma LDL cholesterol levels.
Psyllium husk. I: Effect on plasma lipoproteins, cholesterol metabolism, and atherosclerosis in African green monkeys.
TLDR
Psyllium's effects on plasma and lipoprotein cholesterol concentrations, cholesterol metabolism, and diet-induced atherosclerosis were studied in adult male African green monkeys, and cholesterol absorption, neutral steroid and fat excretion, HMGCoA reductase activity, and body weight were unrelated to psyllum's hypocholesterolemic effects.
Viscosity and fermentability as attributes of dietary fiber responsible for the hypocholesterolemic effect in hamsters.
TLDR
It is shown that greater viscosity of intestinal contents is strongly associated with cholesterol reduction, but that the contribution of fiber fermentation remains uncertain.
Lactose protects against estrogen-induced pigment gallstones in hamsters fed nutritionally adequate purified diets.
TLDR
P pigment gallstones were induced in less than 8 wk in hamsters fed estrogen-supplemented purified diets, apparently through its impact on large bowel metabolism and lactose feeding improved lipid metabolism and reduced gallstone formation.
