What is the Gut-Brain Connection?
The gut-brain connection or gut-brain axis are the names used to describe the communication network that connects your gut and brain.
How does the Gut-Brain Connection work?
The Vagus nerve plays an essential role in the gut-brain connection because it sends information about the state of the inner organs to the brain via afferent fibers.
Our body’s central nervous system has cells called neurons which are also found in our brain and they tell our body how to behave. There are approximately 100 billion neurons in the brain while in the gut we have 500 million neurons that are connected to the brain through nerves in the nervous system.
The gut and brain are connected through chemicals called neurotransmitters. These chemicals produced in the brain control our feelings and emotions
Food That Helps The Gut-Brain Connection
Omega-3 fat found in oily fish such as Tuna can increase good bacteria in the gut and reduce risk of brain disorders.
High-Fiber food such as whole grains, nuts, seeds, fruit and vegetables all contain prebiotic fiber that are good for your gut bacteria. Also prebiotics can reduce stress hormones.
Polyphenol-rich food such as cocoa, green tea, olive oil and coffee all contain polyphenols which are plant chemicals that are digested by your gut bacteria. Polyphenols increase healthy gut bacteria and may improve cognition.
