ANSC 4650 Lecture Notes - Lecture 8: Dysbiosis, Enterocyte, Small Intestine
Document Summary
Key points: nutrition is a powerful tool for managing gi health and disease, fiber promotes intestinal health and helps manage intestinal conditions, benefits of fermentation, bacterial effects (fos/mos) Intestinal immune effects: probiotics offer an additional approach to enhance intestinal fermentation and produce beneficial scfa, fatty acids play a role in managing intestinal inflammation. Fibre: non-digestible, plant based, complex carbohydrate, variable composition, fermentability, and solubility. Intestinal cells designed for butyrate utilization and there for thrive on a diet that provides butyrate. Conclusions from the canine colonic microstructure study: dogs fed fermentable fiber had greater colon mass (per kg body weight, colonic surface area: mass ratio was increased in dogs fed fermentable fiber. Fos used as an energy source by good gut bacteria and not bad bacteria. Synbiotic: prebiotic with a probiotic, energy source used concurrently to increase survival of beneficial bacteria, fructooligosaccharides increase canine intestinal bifidobacteria and lactobacilli*
