Food & Gut Health: How What You Eat Shapes How You Feel

Your gut is often called your “second brain” and there is a good reason for that. Around 90% of your serotonin (your mood‑regulating chemical) is produced in the gut. When your gut is inflamed, unbalanced, or stressed, your mood and energy suffer.

If you have ever experienced IBS, bloating, fatigue, or mood swings after certain foods, you have felt this connection first-hand. I have experienced this myself, and for me it was often linked to overconsumption of certain foods, like coffee and gluten, rather than a true allergy. Small adjustments made a noticeable difference.

The Gut–Brain Link

The gut and brain communicate through the vagus nerve. When your gut is healthy, signals are calm and balanced. When it is irritated, the brain receives stress signals, which can increase anxiety, irritability, and low mood.

Simple Gut‑Friendly Adjustments

• Increase fibre gradually. 

  Fibre feeds your good gut bacteria, improving digestion and mood.

  
  

• Reduce trigger foods. 

  For many people this includes gluten, dairy, or ultra‑processed foods, but it is individual.

  
  

• Eat fermented foods. 

  Yogurt, kefir, kimchi, sauerkraut, and kombucha support gut diversity.

  
  

• Stay hydrated. 

  Water helps digestion and reduces bloating.

  
  

• Eat slowly. 

  Digestion begins in the mouth. Slow eating reduces IBS symptoms and improves nutrient absorption.

  
  

• Add variety. 

  Aim for 20–30 different plant foods per week. Diversity = a stronger gut microbiome.

  
  

Small changes can transform your energy, mood, and overall wellbeing.
