Document Summary
Colonic health benefits of butyrate: primary energy source for colonocytes, reduced inflammatory cytokines, maintenance of tight junctions, regulation of colon ph, promotes cell arrest and apoptosis in colon cancers. Prebiotics feed probiotics: prebiotics support and feed probiotics, prebiotics provide substrate for probiotic s metabolic byproducts (scfa) and therapeutic benefits to gut integrity, prebiotics are primarily soluble fiber and complex sugars. Insulin, oligosaccharides, lactulose, and insoluble fibers to a lesser extent: soluble fiber: benefiber, metamucil, citracel, oatmeal, beans, barley, bran, flaxseed meal, cheerios, avocados, carrots, apples, pears, etc, scfos: short chain, no residue soluble fiber found in nutraflora supplements. Probiotics: food sources of probiotics are generally preferred over supplements, many probiotic supplements fail quality testing, many probiotic bacteria are naturally sensitive to heat, so you want to refrigerate them. Antibiotics: vaccines vs. antibiotics, vaccines are 90% effective, resistant bacteria, overuse of antibiotics has led to over 70% of bacteria becoming resistant at least one antibiotic treatment, misuse and overuse.
