Lesson 09 of 14

Letting microbes do part of your digestion for you.

Fermentation

For thousands of years, humans have used microbes to transform food — turning milk into yogurt, cabbage into sauerkraut, grapes into wine, soy into miso. Fermented foods often introduce live cultures and pre-digested compounds that many people find gentler on the gut.

Common ferments around the world

  • · Yogurt, kefir (dairy)
  • · Sauerkraut, kimchi (vegetable)
  • · Miso, soy sauce, tempeh (soy)
  • · Sourdough (grain)
  • · Kombucha (tea)
  • · Vinegar (many bases)

Something to investigate

Add one spoon of a fermented food to a meal you already like. What changes — flavor, digestion, both?
