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

Enteric bacterium are major microorganisms that colonise military mans gastrointestinal tract- a long tube containing specialised sections such as the mouth, oesophagus, stomach, intestines, rectum and the anus. Gut bacteria apply up 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 c different 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 authority in the gut environment and, changes in dietary nutrients such as, carbohydrates, fats and proteins croupe have a huge impact on the composition of gut bacteria. The digestion of food in the gastrointestinal tr act is vital in humanness, however, humans do not code for all the enzymes required to breakdown non- light substances and so they rely on enteric bacteria to degrade resistant starch, non digestible carbohydrates and mucin (Scott et al. 201352-69). This essay will focus on how gut bacteria back tooth affect weight and, the mutualistic relationship between gut bacteria and the human in maintaining normal health. Gut bacteria keep humans bouncing by stimulating the digestive process within the tumescent intestines. In order for nutrients to be successfully absorbed in the colon, non-digestible carbohydrates are truehearted 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.
