So-called probiotics or fermented foods are helpful to give our gut community a regular exposure to fresh live microbes. As well as eating good-quality cheese (ideally made with unpasteurised milk), consuming natural full-fat yoghurt regularly is healthy for most people. For an even more concentrated dose of multiple microbes, try fermented milk called kefir or fermented tea (kombucha) or add fermented vegetables like sauerkraut or kimchi.
