Your gut is home to a bustling world of bacteria, fungi and even viruses - collectively known as the microbiome. It’s a delicate ecosystem that affects everything from your digestion and immunity to your mood and metabolism.

What is the microbiome?

The human microbiome is made up of trillions of microbes living on and inside your body - most of which reside in your large intestine. In fact, you’re made up of more bacterial cells than human ones. These microbes play vital roles in keeping you healthy by supporting digestion, nutrient absorption and immune function.

Why it matters

Often called the “forgotten organ”, your microbiome influences far more than gut health. It helps produce essential vitamins like B and K, regulates inflammation, supports brain health, and even affects weight balance and heart function. From birth, your gut bacteria begin shaping your immune system and overall wellbeing.

How to nurture a healthy microbiome

A diverse diet rich in plant-based, fermented and fibre-filled foods can help your gut thrive. Try adding:

  • Fermented foods such as kimchi, kefir or sauerkraut
  • Whole fruits, vegetables and legumes for natural prebiotics
  • Probiotic-rich foods to top up beneficial bacteria
  • Fewer artificial sweeteners and processed foods

These small changes can support digestion, lower cholesterol and stabilise blood sugar.

Apple cider vinegar and the microbiome

Raw, unfiltered apple cider vinegar - especially when it contains the live ‘Mother’ - is naturally rich in probiotics. The acetic acid it contains aids digestion, encourages good bacteria to flourish and may help balance your body’s pH. At Willy’s, our organic ACV is alive with the Mother, meaning every drop is teeming with beneficial microbes.

Simple ways to enjoy ACV daily

  • Mix 1–2 tablespoons in a glass of water before meals
  • Whisk into olive oil for a quick salad dressing
  • Add a dash to your morning smoothie
  • Stir a spoonful into warm water with honey for a soothing tonic

Other gut-friendly favourites

Yoghurt, almonds, sourdough, kombucha, garlic, ginger, bananas and even Brussels sprouts all feed the microbiome and keep things balanced.
