Dietary Protein Supplementation Increases Peak Bone Mass Acquisition in Energy-Restricted Growing Rats
Peak bone mass is a major determinant of osteoporosis pathogenesis during aging. Respective influences of energy and protein supplies on skeletal growth remains unclear. We investigated the effect of a 5-mo di...

Comparison of native or reformulated chicory fructans, or non-purified chicory, on rat cecal fermentation and mineral metabolism
Chicory inulin has been identified as an effective prebiotic to promote active fermentation and lactobacilli proliferation in the large intestine, and to enhance calcium (Ca) digestive absorption and depositio...

Influence of High and Low Protein Intakes on Age-Related Bone Loss in Rats Submitted to Adequate or Restricted Energy Conditions
Low energy and protein intake has been suggested to contribute to the increased incidence of osteoporosis in the elderly. The impact of dietary protein on bone health is still a matter of debate. Therefore, we...

Organic potassium salts or fibers effects on mineral balance and digestive fermentations in rats adapted to an acidogenic diet
Fibers and potassium (K) organic salts in plant foods are liable to affect Ca and Mg balance at digestive and renal levels, respectively. K organic salts could counteract the acidifying effects of western diet...

Mice chronically fed a westernized experimental diet as a model of obesity, metabolic syndrome and osteoporosis
Most studies in animals use diets with several features (for example low-fat, rich in micronutriments), likely to be strongly protective against chronic diseases.

Effect of carrot intake on cholesterol metabolism and on antioxidant status in cholesterol-fed rat
Vegetables are major dietary sources of fibers and antioxidants such as carotenoids, polyphenols and vitamin C which contribute to explain their protective effects against cardiovascular diseases.

Cholesterol-lowering effects of guar gum: Changes in bile acid pools and intestinal reabsorption
Soluble fibers such as guar gum (GG) may exert cholesterol-lowering effects. It is generally accepted that bile acid (BA) reabsorption in portal blood is reduced, thus limiting the capacity of BA to down-regul...

The cholesterol-lowering effect of guar gum in rats is not accompanied by an interruption of bile acid cycling
A viscous hydrocolloid (guar gum, GG; 2.5% of the diet) or a steroid sequestrant (cholestyramine; 0.5% of the diet) was included in semipurified diets containing 0.2% cholesterol to compare the cholesterol-low...

The cholesterol-lowering effect of guar gum is not the result of a simple diversion of bile acids toward fecal excretion
The effects of partially hydrolyzed, nonviscous, guar gum (PHGG) on cholesterol metabolism and digestive balance have been compared with those of native guar gum (GUAR) in rats adapted to 0.4% cholesterol diet...

Effectiveness of resistant starch, compared to guar gum, in depressing plasma cholesterol and enhancing fecal steroid excretion
Amylase-resistant starch (RS) represents a substrate that can be administered in substantial amounts in the diet, in contrast to gel-forming polysaccharides, such as guar gum (GG). The aim of this work was thu...

Resistant starch is more effective than cholestyramine as a lipid-lowering agent in the rat
Amylase-resistant starch (RS) represents a substrate for the bacterial flora of the colon, and the question arises as whether RS shares with soluble fibers common mechanisms for their lipid-lowering effects. I...
