General gut health
The everyday foundations of a happy gut — fibre variety, the microbiome and lifestyle.
Feed your microbiome variety
Your gut is home to trillions of microbes that thrive on variety. A well-known target is around 30 different plant foods a week — and that counts fruit, veg, wholegrains, legumes, nuts, seeds, herbs and spices. Fermented foods like yoghurt, kefir and kimchi can add to the mix. It's about diversity, not restriction.
It's not just food
The gut and brain are closely connected, so sleep, movement, stress and hydration all shape how your gut feels. Regular meals, staying active and managing stress often help as much as any single food.
Myth-busting
"Detoxes", cleanses and most gut supplements promise a lot and deliver little — a varied, mostly whole-food diet does the real work, and your liver and kidneys handle the actual "detoxing". If you're considering a supplement, check with your doctor or dietitian first.
