“The contributions of microbes to multiple aspects of human physiology and neurobiology in health and disease have up until now not been fully appreciated.“
Many people have said the human gut is like a “second brain.” With trillions of microbes, the digestive tract of the human gut can influence many things such as your metabolism, nutrition, immune function, and even your happiness. New research continues to show links between the brain and the health of the gut.
For example, a study from Lund University found that “unhealthy intestinal flora can accelerate the development of Alzheimer’s disease.” Alzheimer’s disease is an extremely common form of dementia or memory loss. It is caused by the death of many brain cells, which progressively decreases the size of the brain and the number nerve cells and connections. This study showed that mice with Alzheimer’s have a different bacterial profile in their guts than mice without this disease. Dr. Frida Fak Hallenius said that “Alzheimer’s is a preventable disease and in the near future we will likely be able to give advice on what to eat to prevent it. Take care of your gut bacteria, by eating lots of whole-grains, fruits and vegetables.”
After these discoveries, researchers are looking deeper into how bacteria can affect brain pathology. One of their ideas is that the bacteria may affect T-cells in the gut, which controls inflammatory processes both in the gut and brain. Therefore, if we can find a way to increase the health of the gut, we can reduce inflammation and brain damage. Alzheimer’s, while it is one of the most feared diseases, is preventable to in extent and if not preventable, there are several ways to delay it. The human gut microbiome has a huge impact on your health and your brain’s health. If scientists can continue to discover how to make your gut as healthy as possible, Alzheimer’s could soon be a thing of the past.
