Question
Chapter 24.11, Problem 1MQ
Summary Introduction
Microbial community dysbiosis (disturbance) is associated with the cause of many diseases. If there is a disturbance in the microbial diversity of intestine, it leads to inflammatory bowel disease (IBD) and obesity.
These diseases can be treated by the intake of microbial cultures which have the ability to improve the gut microbial community and therefore help to treat the disease. These beneficial microbial cultures are termed as probiotics and some plant nutrients termed as prebiotics are also used to enhance the gut microbial health.
