Gut health is something that can benefit so many areas of your life.

How to Improve Your Gut Health to Benefit Your Mental Health 

Our gut health has a profound impact on our physical and mental health. When most people think about the gut, they usually think of the intestines and digestive issues. However, in reality the gut is much more powerful! 

The gut actually has an even larger impact on our mindset and mental health than most people  realize. You see, in the gut is where our bodies manufacture 90% of our serotonin, or our happy chemical.

This means that your gut health has an impact on your mood and how happy you feel. 

So, if you’ve ever heard the term you are what you eat, it might ring more true than you originally thought!

One of the great things about the impact of gut health on our mood, cognition, and sense of well being is that we can use this tool to our advantage. We can actively play a role in our mental health by taking care of our gut health. 

What creates a healthy gut? 

The gut likes colorful, whole foods from the earth. Our bodies are meant to get nutrients from foods that are naturally full of vitamins, minerals, fiber, and protein. 

In the Standard American Diet (often referred to as the SAD diet) we often resort to many packaged foods which are leached of nutrients and contain chemicals, toxins, and preservatives. These foods are more likely to have unhealthy oils and sweeteners that our body cannot use for energy, so they often get stored as fat. 

These types of ingredients are harmful to the gut and can create illness or disease. 

What happens if the gut is unhealthy? 

The gut can become unhealthy for many reasons. Food sensitivities, antibiotics, stress, toxins, chemicals, disease and daily diet are a few common culprits. When the gut lining gets small holes in it, food particles, toxins and chemicals are able to leak through the lining and into the bloodstream. This is known as leaky gut, which creates inflammation in the body. 

Inflammation in the gut is directly tied to inflammation in the brain. This means that you could be unfocused, anxious or depressed in reaction to what is going on in your intestines or digestive system. 

This is one of the reasons why gut health is key to our mental health. What we put into our body truly matters!

How Do We Achieve Gut Health

To have a healthy gut, we need to remove the bad and bring in the good. This is a simple start to a healthier gut. We have trillions of bacteria in our gut. We get into trouble when our gut environment, or microbiome, becomes imbalanced. We end up having more bad bacteria than good. We want to change that to have more of the good bacteria to create a healthy microbiome. 

A quick way to boost gut health is to cut out packaged and processed foods that do not come from the earth. These are often void of key nutrients and are packed with additives, many that are difficult to pronounce! This is a sign that they are not natural. 

We also need prebiotics and probiotics in our diet. Probiotics are healthy bacteria that nourish our gut. Prebiotics are the food that probiotics eat to flourish. 

You can find prebiotics in many fruits and vegetables from the earth such as apples, bananas, and asparagus. Probiotics are found in fermented foods such as homemade pickles, sauerkraut, kimchi and miso. You can also get probiotics in supplement form to aid in a healthy microbiome. 

Positive Benefits of a Healthy Gut 

As we discussed before, a healthy gut positively impacts both physical and mental health. When you improve your gut health, you often get these benefits: 

  • Weight loss 
  • Increased energy 
  • Improved focus 
  • Clearer skin
  • Positive mood
  • Decreased anxiety 

We get these mental health benefits because our gut is known as our second brain. We actually have more nerves that go from the gut to the brain than from the brain to our gut! This shows how big of an impact our gut has on our brain function. 

Research has shown that many neurological diseases including Parkinson’s have been shown to start in the gut rather than the brain. For years, we have believed that we have little control over these devastating neurological diseases. However, research shows that we do have control over our gut health which has a profound impact on our cognition and brain health. 

Thus, it is key for us to take care of our gut health as soon as we can. 

How Do We Start Taking Care of Our Gut Health Today

In summary, eating foods from the earth is a great, easy place to start. Ditch the packaged foods and go for naturally occurring fruits, veggies, legumes, lean meats and proteins. Next, skip the toxins. Try to eat organic produce when possible. There are many pesticides that create havoc on our hormones and harm our gut health. Next, add in prebiotic and probiotic foods. This will enrich your gut microbiome and allow healthy gut bacteria to flourish.
