1. According to Bonnie Bassler in the video TedTalk, the human body is considered 90% prokaryotic because there are ten times more bacterial cells than human cells on a human being. Humans have approximately 30,000 genes, but you actually have ten times more bacterial genes. Bassler considers humans about 90% bacterial. These bacterial cells literally almost do everything, from digesting our food, making our vitamins, keeping us healthy, etc. This is why we are considered 90% prokaryotic, due to the huge amount of bacterial cells within us (Bassler, 2009).

An experiment has been made by Dr. Nicholson on people who are obese. He uses Roux-en-Y, which is a procedure that basically reduces the amount of food the body can absorb. On 80% of his cases, the obesity condition vanishes. He decided to use this procedure on mice and he found that the Roux-en-Y caused the composition of the gut microbiome to change. Dr. Nicholson believes this explains the sudden disappearance of type 2 diabetes in people. He suspects that part of the web is regulated by the microbiome in a similar way to the formic acid role in the high blood pressure case. He concludes that the intestinal will bypass and disrupt the microbiome. This causes the signal to reset and the diabetes will eventually vanish (The Economist, 2012). There is a study that provides evidence on there being a linkage between metabolic diseases and bacterial populations in the gut. The study compared the differences between the composition of intestinal microbiota in people with type 2 diabetes and used non-diabetic people as the control. The study consisted of 36 male adults, with 18 of them having the diabetes. The results showed that the men with type 2 diabetes are associated with compositional changes in intestinal microbiota. When combining microbiota with metabolic diseases (obesity), the glucose level tolerance should be considered. This will broaden more ways to maintain metabolic diseases by modifying the gut microbiota (Larsen,
