Healthy Gut Starts With Fermentation
Your gut is home to trillions of bacteria, and what you eat can either feed them or throw them off balance completely. Fermented foods offer a natural way to nourish your microbiome while packing in surprising flavors. These gut-friendly staples have been trusted in cultures around the world for generations. Make some of these swaps on your plate, and your digestion might just thank you.
