Include foods rich in probiotics, such as yoghurt/curd, kefir, sauerkraut, tempeh, kimchi, miso, kombucha, buttermilk, natto, and cheese. Eat fibre-rich foods like brown rice, baked potato, berries, cereal, oatmeal, and vegetables to promote digestion. Eat small meals at regular intervals so that your stomach does not have to work as hard or as long.
