AIN-93 purified diets for laboratory rodents: final report of the American Institute of Nutrition ad hoc writing committee on the reformulation of the AIN-76A rodent diet.
TLDR
Two new diets may prove to be a better choice than AIN-76A for long-term as well as short-term studies with laboratory rodents because of a better balance of essential nutrients. Expand
Selected indigestible oligosaccharides affect large bowel mass, cecal and fecal short-chain fatty acids, pH and microflora in rats.
TLDR
Dietary incorporation of fermentable, indigestible oligosaccharides, by providing SCFA, lowering pH, and increasing bifidobacteria, may be beneficial in improving gastrointestinal health. Expand
Nutritional Responses to the Presence of Inulin and Oligofructose in the Diets of Domesticated Animals: A Review
TLDR
An extensive review of the effects of these oligosaccharides on gastrointestinal characteristics and systemic metabolism of carbohydrates, nitrogen, lipids, and minerals in dogs, cats, horses, calves, pigs, poultry, and rabbits and the possible substitution of antibiotics with fructans in animal diets is presented. Expand
Supplemental fructooligosaccharides and mannanoligosaccharides influence immune function, ileal and total tract nutrient digestibilities, microbial populations and concentrations of protein…
TLDR
It is suggested that dietary supplementation of FOS and MOS may have beneficial effects on colonic health and immune status of dogs. Expand
Phylogenetic Characterization of Fecal Microbial Communities of Dogs Fed Diets with or without Supplemental Dietary Fiber Using 454 Pyrosequencing
TLDR
The data are among the first to characterize the healthy canine gut microbiome using pyrosequencing and provide a basis for studies focused on devising dietary interventions for microbiome-associated diseases. Expand
Phylogenetic and gene-centric metagenomics of the canine intestinal microbiome reveals similarities with humans and mice
TLDR
This study is the first to use a metagenomics approach to characterize the phylogeny and functional capacity of the canine gastrointestinal microbiome and hierarchical clustering of several gastrointestinal metagenomes demonstrated phylogenetic and metabolic similarity between dogs, humans and mice. Expand
Evaluation of wet and dry distillers grains and wet and dry corn gluten feeds for ruminants
Fructooligosaccharides and Lactobacillus acidophilus modify gut microbial populations, total tract nutrient digestibilities and fecal protein catabolite concentrations in healthy adult dogs.
TLDR
Overall, FOS appeared to enhance indices of gut health by positively altering gut microbial ecology and fecal protein catabolites, whereas LAC was more effective when fed in combination with FOS rather than fed alone. Expand
Consumption of cereal fiber, mixtures of whole grains and bran, and whole grains and risk reduction in type 2 diabetes, obesity, and cardiovascular disease.
TLDR
It is found that consumption of foods rich in cereal fiber or mixtures of whole grains and bran is modestly associated with a reduced risk of obesity, T2D, and CVD. Expand
Viscosity as Related to Dietary Fiber: A Review
  • C. Dikeman, G. Fahey
  • Chemistry, Medicine
  • Critical reviews in food science and nutrition
  • 1 December 2006
TLDR
The following article provides a review of viscosity as related to dietary fiber including definitions and instrumentation, factors affecting viscosities of solutions, and effects of viscous polysaccharides on glycemic response, blood lipid attenuation, intestinal enzymatic activity, digestibility, and laxation.
