Does Disease Begin with Gut Health?

Updated: Mar 12, 2022

3 Steps to Prevent Disease

What is gut health?

There has been lots of talk about what has become known as "gut health". The Johns Hopkins Medical Center website, one of the most well-respected hospitals and Medical Schools in the United States, says there is a good reason for this. Hidden within the walls of your digestive system is what is known as "your second brain" and this "brain in your gut" is changing the way that we look at the links between mood, digestion, health and even the way your think.

Does Disease Begin with Gut Health?

The answer is NO. Not all the diseases start in the gut. For an example, it doesn't apply to the genetic or inherited diseases. But, there are evidences that lots of chronic metabolic diseases do. They begin in the gut. We can prevent these diseases by following some easy steps.

Step 1: Know What the Second Brain is and Why Does it Matter

This "little brain" is called the "enteric nervous system" or ENS and it comprises of two thin layers of over 100 million nerve cells that line your GI tract from your esophagus to your rectum. The role of the ENS is to control digestion, including swallowing to releasing the enzymes that help break food down, to the control of blood flow, which aids with both nutrient absorption and elimination. The ENS communicates with our brain with significant results.

When you have an unhealthy gut, the symptoms of that can manifest themselves in other parts of your body. It's your body trying to tell you that something is wrong or out of balance. Studies have found that increasing your gut health can lead to improvement in:

  • Immune function - 80% of our immune system is located in our gut

  • Brain function

  • Symptoms of anger, sadness, and depression

  • Obesity

  • Toxin levels in the body

  • Irritable Bowl Syndrome (IBS)

  • Allergies

  • Chronic Fatigue Syndrome

What Results? How is this even Possible?

The ENS may sense things that our cerebral brain cannot. Evidence has been found that when the GI tract is irritated, it sends signals to the central nervous system (CNS), which can trigger our mood and ultimately affect it. When you consider that between 30-40% of the population has bowel problems of some kind, and that a higher percentage of these individuals develop depression and/or anxiety, it's easy to see how there could be a connection.

Our bodies are filled with bacteria - good and bad. There are more bacteria in a human body than there are cells, and there are an estimated 100 trillion microorganisms living in our bowels alone. The key here is to have more good than bad bacteria in your gut - the fancy name for good microorganisms is probiotics. Probiotics help us do things like:

  • Digest food

  • Absorb nutrients

  • Break down medications, and

  • Kill some of the bad bacteria that lead to infection

Step 2: Get More Probiotics

There are quite a few ways to get probiotics, but one of the easiest is to take a supplement called a probiotic. You will find many different kinds under different brand names and it would be a good idea to talk to your physician or pharmacist to see which is the brand that they recommend.

There are foods that are also high in probiotics. Unfortunately, many of them are not widely available or thought very high of in America. These foods include:

  • Unpasteurized cheese - Gouda, Cheddar, Provolone, and Gruyere are some examples

  • Buttermilk

  • Kefir

  • Miso

  • Sauerkraut

  • Apple Cider Vinegar (ACV)

  • Yogurt - be sure to read the labels on the different yogurts

Getting more probiotics into your system is one of the best ways that you can improve your gut health.

More Probiotics, What Else?

The ones we hate. The ones that your grandmother and mother told you. Stress Less. Laugh More.

Stress, especially long-term stress, not only affects our gut bacteria, but it also affects the production of hormones and neurochemicals that communicate with our brain. When it is long-term stress, these chemicals and hormones can change permanently (unless you specifically work to change them back). Long-term stress may also lead to gastroesophageal reflux disease (GERD), stomach ulcers, IBD, IBS, and potentially food allergies.

Laughter really is the best medicine. It helps to reduce stress and floods your body with the happy hormones and chemicals that make the good overtake the bad. There was even a study conducted (link below) where researchers studied healthy people, as well as those with atopic dermatitis - a disease that is often associated with imbalances in gut bacteria. The researchers had the participants watch funny movies daily for one week. In only one week, the patients' gut flora had changed and resembled the healthy participants.

Step 3: Play in the Dirt!

This is true both literally and figuratively. Gardening is good for you because it gets you outside, gives you exercise, and putting your hands in soil introduces your body to the microorganisms that are found on the plants and in the ground. In a more figurative way, stop killing all the bacteria. They have recently stopped putting anti-bacterial agents in things because humans are killing all the bacteria, the good and the bad. And what is happening? The bad bacteria are getting stronger and the good bacteria is dying.

Studies have shown that kids who grow up with a dog have both a lower risk of allergies and a healthier immune system. Dogs are associated with a type of house dust that actually exposes us to important strains of bacteria. Dogs also work somewhat like a probiotic, helping develop healthy bacteria that boost your immune system, stopping you from getting ill, and possibly reducing allergies. Dogs also help you, or in some cases force you, to exercise more and help relieve stress in your life.


It may well be that a large part of maintaining good health is maintaining good gut health. There are many ways you can do this, including exercise, and learning to listen to your body; however, some of the easiest changes that you can make are to:

  • Get plenty of probiotics - through supplements and food

  • Laugh

  • Manage your stress better

  • Don't over sterilize or try and kill all bacteria
