Gut health affects far more than just digestion — it influences immune function, mental health via the gut-brain axis, energy levels, and even skin health. The gut microbiome contains trillions of bacteria that perform essential functions.
The most evidence-based ways to improve gut health: eat more fibre. Most people eat 15g daily when the target is 25-30g. Fibre feeds beneficial gut bacteria. Aim for 30 different plant foods per week — this is easier than it sounds when you count spices and herbs.
Fermented foods introduce beneficial bacteria: yoghurt with live cultures, kefir, kimchi, sauerkraut, and kombucha. Even a small daily serving helps. These are especially useful after antibiotics, which can wipe out gut bacteria.
Avoid unnecessary antibiotics. Reduce ultra-processed food consumption — emulsifiers and artificial sweeteners appear to negatively affect the microbiome. Manage stress, which directly impacts gut motility and bacterial composition via the gut-brain axis.
