Leaky gut, autoimmunity, and mental health – What are the links?

The gut (a.k.a. digestive tract) is not just a tube that absorbs nutrients and gets rid of waste – it’s a complex alive system that’s a huge foundation of health. And not just gut health, but the overall health of our bodies and minds. We know how important it is to get all of our essential nutrients from food – and this is a big part of what our digestive tract does. But, there is way more to the story than just that.

When the gut is not working properly, symptoms can appear. Yes, typical gut and abdominal symptoms, but also other seemingly unrelated symptoms. Did you know that things like allergies, autoimmunity, and mental health have been linked with gut problems?

Let’s look at one gut problem in particular (you may have heard about this lately) – leaky gut. This literally involves tiny “leaks” in our gut lining that can allow more than just needed nutrients and water into our bodies. Researchers are looking at this, and I want to share the latest with you, as well as give you some helpful strategies to optimize your gut health, for overall health!

What is “leaky gut” linked with?

Gut structure – Three layers of our gut lining

Leaky gut and our gut microbes

Leaky gut, allergies, and autoimmunity

Leaky gut and mental health

What you can do about leaky gut


Leaky gut, or “intestinal permeability” is linked with many conditions of the gut, the body, and the mind. While research is still figuring out exactly how this happens and what comes first, there are definitely steps you can take today to help optimize your health.

Eat more whole, unprocessed foods, and ditch ultra-processed foods. Reduce alcohol consumption and consider probiotics. And, if you think you may have a food intolerance, be sure to speak with your healthcare professional.
