The human gut and brain are primarily connected by the vagus nerve, which allows for bidirectional communication between your brain and your gut. This connection means the brain can control your gut's digestion, inflammatory responses, etc. Meanwhile, your gut can influence your brain by responding to gastrointestinal stress with depression, mood swings, anxiety, etc.
The gut affects our brain this is clear now, however, the reasoning behind it is a combination of factors. The ability of our gut to affect anxiety, depression, and general mood swings is due to the fact that 90% of the body's serotonin receptors are located within the gut. In addition to this things like our diet are what can cause problems, a diet without all the proper nutrients the gut needs to maintain stability will cause problems for your gut health and therefore cause problems with your mood regulation.
An unhealthy gut can cause depression, increased stress, and even memory problems.
While it is obvious that there is a multitude of benefits to maintaining a healthy gut, recent studies suggest taking care of your gut health can also help reduce the likeliness of certain chronic diseases, such as:
Multiple Sclerosis (MS)
Irritable Bowel Syndrome (IBS)
There are a plethora of things you can do to maintain a healthy gut, but some of the best ways include exercising, drinking plenty of water, meditation, and of course having a healthy diet.
The term 'healthy' diet can be subjective depending on the goal or the specific health afflictions being aimed at improving, however, for overall improvement of your gut health the following foods are great additions to your diet.

Fermented Foods are also great for your gut health as they can help reduce inflammation and improve your intestinal health.
Whole grains are also helpful as they add a bit of fiber to your diet and help out lots of the microbes in your gut.
