First: rule out medical causes

If you have ongoing digestive symptoms, speak to your GP before trying to fix them yourself. Food supplements are not a treatment for medical conditions.

Step 1: feed your gut bacteria

Fibre from a wide range of plants is the single most useful thing for most people. Build up slowly.

Step 2: add friendly bacteria

Fermented foods or a probiotic supplement can add friendly bacteria to your diet.

Step 3: reduce what works against your gut

Highly processed foods, excess alcohol, smoking and poor sleep can all affect your gut. Only take antibiotics when prescribed – read about gut health after antibiotics.

Step 4: support digestion

Eat slowly, chew well and try not to eat late at night.

Step 5: be consistent

Your gut changes over weeks, not days. Pick habits you can keep.
