The connection between the brain and the gut is undeniable. There are tons of neurons and good bacteria found in the walls of the gut that are responsible for more than just digestion. They keep our immune system healthy, as well as play a crucial role in our mental health. This is why people with celiac disease, an autoimmune disorder triggered by gluten consumption, or any kind of gluten intolerance may be prone to depression and anxiety as a result of eating gluten.

This Is Your Brain On Gluten

Research shows that people who eat gluten tend to have significantly increased symptoms of depression. People with celiac disease suffer from depression at much higher rates than others. The same goes for anyone with a gluten intolerance, mild or severe.

While the reason for the connection between gluten consumption and mental health is uncertain at this point, the fact that the gut and the brain are so clearly linked might have something to do with it. Another speculation is that the gluten is directly interacting with the brain somehow.

Why Am I Tired All The Time?

Studies also show a clear link between gluten consumption and tiredness. For some, it might just be the carbohydrates weighing them down. This is not a serious health issue, but it is still no good.

For others, gluten intolerance is to blame, as their immune reaction to eating gluten prevents nutrients from being absorbed. This, in turn, causes the brain, organs, and nervous system to miss out on necessary nourishment, hence the fatigue.

An Unlikely Culprit

While those with celiac disease have immediate physical symptoms that make their extreme gluten intolerance obvious, that is not the case with people who have non-celiac gluten intolerance. In fact, because some of the major symptoms of gluten intolerance are mental, such as fatigue and depression, it can be hard to tell if gluten is the cause.
If you think you might have a gluten intolerance based on unexplainable tiredness and depression, the best way to test it out is to cut gluten out of your diet for a while. If you notice these symptoms disappearing, you probably are gluten intolerant on some level. Your mental health and productivity will thank you for cutting gluten out of your diet, if not completely, then at least mostly.
