Which Fermented Food is Best for Gut Health?

While there’s no single “best” fermented food for gut health, a variety of options can provide different strains of beneficial bacteria. This diversity can enhance the overall health of your gut microbiome. Keep reading to discover the top 10 fermented foods you can include in your diet.

Top 10 Fermented Foods for Gut Health:

Recipe: Homemade Kefir

Kefir is a versatile fermented dairy product that’s easy to make at home. Here’s a simple recipe using UK measurements:


  • 1-litre whole milk
  • 2 tablespoons kefir grains
  • A glass jar
  • Non-metal stirring utensil


  1. Place the kefir grains in a glass jar.
  2. Pour the whole milk into the jar.
  3. Stir gently with a non-metal utensil.
  4. Cover the jar with a clean cloth and secure it with a rubber band.
  5. Let the mixture sit at room temperature (around 18-25°C) for about 24-48 hours. The longer it ferments, the tangier it will become.
  6. After fermentation, strain out the kefir grains and transfer the liquid to another clean jar for storage.
  7. Refrigerate the kefir and enjoy it chilled.
