As previously mentioned, the GI system hosts about 100 trillion bacteria, so a diverse gut microbiome is important for a proper digestion and nutrient absorption. Each bacteria species possess a special job, depending on their unique characteristic and metabolic pathways. GI bacteria break down organic matters to smaller compounds, making essential vitamins and regulating the nutrients absorptions. A poor GI system and lack of diversity leading to digestive problems and nutri

Gut bacteria plays a role in cancer development, progression, and treatment response. Gut bacteria imbalance can lead to inflammation, which can trigger diseases like colorectal cancer. Some bacteria like ETBF, a pathogenic strain of bacteroides fragilis can trigger an inflammatory that accelerates the formation of cancerous tumors in the colon that called tumorigenesis. Cancer Progression The gut bacteria can affect the progression of cancer by interacting with the immune sy

A community of 100 trillion bacteria and over 5,000 different species of bacteria, as well as viruses, fungi, and parasites are the permanent residents of the human GI system. The number of bacteria in the GI system is larger than the number of stars in the Milky Way galaxy. The number of stars in the Milky Way is between 100 and 400 billion. The gut bacteria or gut microbiota contain a significant portion of the immune system, about 70 to 80 percent of the body immune cells

The gut and liver are connected through the gut-liver-axis. Gut bacteria metabolize nutrients and break down the fiber into short chain fatty acids (SCFAs) which have anti-inflammatory Properties. SCFAs can improve the insulin sensitivity which prevents fatty liver. Chronic insulin resistance can cause nonalcoholic fatty liver disease, since the body is less responsive to insulin that increases the fat accumulation in the liver. Gut bacteria can break down complex carbohydrat
