Immune System:
How the gut microbiome affects your immune system
Snapshot
Your gut microbiome significantly shapes your immune system. A balanced microbiome provides a robust immune foundation, helping prevent allergies, autoimmune disorders, and infections. Our microbiome test gives you clear, personalised insights and practical nutritional advice to strengthen your immune system from within.
How your microbiome affects your immune system
Your gut hosts trillions of microorganisms—including beneficial bacteria, viruses, and fungi—that actively influence your immune health. When your microbiome is balanced, it helps your body fight infections, allergies, and autoimmune conditions more effectively. However, an imbalance (dysbiosis) weakens your immune defences, making you more susceptible to illness, allergies, and inflammation.
The Gut-Immune Connection Explained
Around 70% of your immune system lives in your gut, highlighting how vital gut health is for immunity. Your microbiome directly influences immune responses, inflammation, and even allergic reactions. A healthy microbiome means a stronger, better-functioning immune system that can efficiently protect against infections and disease.
Strengthening your gut to boost immunity
Yes—improving your gut microbiome really does strengthen your immune system! Restoring balance in your gut flora helps your immune system work optimally. The following steps are especially effective:
​
Incorporate probiotic foods
Probiotics are foods containing live, beneficial bacteria that enhance gut balance and support immunity naturally. Great examples include yoghurt, kefir, kombucha, and fermented foods like sauerkraut or kimchi.
​
Include prebiotic foods
Prebiotics are plant fibres that feed beneficial gut bacteria, promoting a healthy and diverse microbiome. Prebiotic-rich foods include oats, bananas, onions, garlic, asparagus, and Jerusalem artichokes.
​
A diet rich in plant-based fibres is essential because your gut bacteria thrive on these fibres, improving your microbiome and immune function.
