Gut Bacteria: How Can It Affect Weight and Health? Essay examples -- ga

Enteric bacteria atomic number 18 major microorganisms that colonise humans gastrointestinal tract- a capacious tube containing specialised sections such as the mouth, oesophagus, stomach, bowels, rectum and the anus. Gut bacteria cast off up approximately 95 percent of the total cells in the body, with the colon containing the densest microbial communities (Gibson, Rastall and Fuller 2008 52). Human gastrointestinal tract consists of 100 divers(prenominal) prokaryotic species, and with two bacterial species, firmicutes and bacteroicidetes dominating them (Brooker et al. 2011 559). The general make up of enteric bacteria is influenced by various factors including microbial species obtained from birth, use of antibiotics, dietary intake and genetic material. Diet plays a major role in the gut environment and, changes in dietary nutrients such as, carbohydrates, fats and proteins can obtain a huge impact on the composition of gut bacteria. The digestion of nourishment in the ga strointestinal tract is vital in humans, however, humans do not code for all the enzymes required to breakdown non-digestible substances and so they cuss on enteric bacteria to degrade resistant starch, non digestible carbohydrates and mucin (Scott et al. 201352-69). This hear will focus on how gut bacteria can propel weight and, the mutualistic relationship between gut bacteria and the human in maintaining normal health. Gut bacteria keep humans healthy by stimulating the digestive process within the large intestines. In tack together for nutrients to be successfully absorbed in the colon, non-digestible carbohydrates are degraded by beneficial gut microbial. One example of an anaerobically respiring bacterium which dominates the large intestine is bacteroide thetaiotaomicron. This bacteri... ... from 29 August 2013Willey,J., Sherwood, L., Woolverton, C.
