How Diet Affects Gastrointestinal [GI] Health
Many people ask us how diet can affect the GI system. One important role of nutrients is to keep the GI lining strong. Bacteria are a major part of the microbiome that lives inside of the colon and rectum. Bacteria have both helpful and harmful functions. When you eat plant-based foods and whole grains, that maximizes growth of the helpful bacteria. These bacteria digest fiber to form helpful products that keep the colorectal lining strong. A strong lining has tight connections between the cells.
Some bacteria, on the other hand, produce harmful products. Weak connections between cells in the lining let harmful products leak in. This activates our immune cells. The secretions from the activated immune cells are meant to destroy the harmful bacterial products. However, if this keeps on happening over time, the immune cell secretions do result in damage to the cells lining the colon and rectum, and this increases the chances of cancerous changes happening.
