Each of these foods starts off as bitter, bland or simply indigestible, but is transformed by microbes into something delicious.

In certain foods like sourdough, soya, yoghurt and miso, these microbes add an additional health kick. “Fermentation removes some toxins from foods, increases B-vitamins, and generates other unique nutritive compounds. But the most profound benefit comes from the bacteria themselves, which are alive and intact in cultured foods,” says Sandor Katz, writer and fermentation revivalist. A good example is the yoghurt we make at home: it’s made by heating milk to kill unhealthy bacteria, then a dollop of existing yoghurt with live culture is added and the mix is allowed to ferment for a few hours. This becomes an all-you-can-eat buffet for the healthy bacteria that do things like consume the milk’s hard-to-digest lactose, transforming it into lactic acid, a by-product of digestion-aiding enzymes.
