Can a Healthy Gut Support Your Immune System?

You may not immediately associate gut health with immunity, but when 70-80% of the immune system is housed in the gut, the two are more linked than what we initially think. In fact, it was suggested by Hippocrates (also known as the “founding father of modern medicine”) over two thousand years ago that all disease begins in the gut. Of course, that’s quite a vast statement to suggest that all diseases start here, and we know now that it’s not strictly true.

However, over the years, medical research has certainly shown that the gut and immune system are closely linked, but exactly how are the two related? Today, we’re looking at the relationship between the immune system and gut health, along with a few tips as to how you can keep yours running smoothly at the same time!

Healthy Gut, Healthy You? 

So, we all know that the gut microbiome is the term for the collection of bacteria and other microscopic organisms found in our intestines, and it actually starts doing it’s important work from the moment we’re born. As we grow, it will contain more and more species of microbes, also known as “diversifying,” and the more diverse our microbiome, the better it is for our gut health. Not surprisingly, the diversity of our microbiome is affected by what we eat, illustrating why a healthy diet is important for our digestive health. 

The microbiome in our gut is responsible for a number of different functions, including breaking down fibre and absorbing nutrients, but it’s also responsible for controlling our immune system and how our bodies respond to infection. The two essentially work together to support one another throughout our lifespan - the immune system supports the growth of bacteria, while the bacteria contributes towards the development of healthy immunity cells and how they respond to infection.

Naturally, there are certain factors that can upset the balance of good bacteria in the gut which can then start to negatively affect our immune system, as well as causing other symptoms such as constipation, bloating and diarrhoea. According to Healthline, things that can upset your gut bacteria include: 

  • Junk food and a lack of prebiotics in the diet
  • Alcohol
  • Smoking
  • Stress 

Antibiotics have also been known to harm the good bacteria in the gut. While they’re there to treat common illnesses caused by bacteria, they actually affect all bacteria, good and bad, which will affect the diversity of our gut flora. 

Probiotics & Prebiotics

One way to support your gut health and immunity can be through probiotics and prebiotics, which will help to ensure the correct balance of bacteria. Probiotics are live “good” bacteria and can be found in live yoghurt and fermented foods such as sauerkraut, and are a great way to give your gut flora a boost. Prebiotics on the other hand, promote the growth of good bacteria in the gut and can be found in certain fruits and vegetables, as well as our delicious range of Troo products
