Low-Sugar Fermented Foods, Gradually Increased

Add 1 to 4 servings per day of refrigerated, live-culture fermented foods such as kimchi, sauerkraut, kefir, natto, or plain yogurt, and increase intake gradually if you are not used to them. The emphasis is on low-sugar, minimally processed versions rather than shelf-stable or heat-killed products. This pattern is used to boost gut microbiome diversity and support lower inflammation, with possible downstream benefits for gut barrier function and serotonin production.

“So really important to take these fermented foods in addition to fiber.”
