Are fermented foods allowed on keto?

Fermented keto foods are an excellent choice for gut health [1]. You can eat raw fermented foods such as sauerkraut, kombucha, kimchi, dairy or coconut kefir, and raw, full-fat plain yogurt. However, be very careful with store-bought ‘healthy’ foods as they still often sneak in the sugars. Fermented foods are all pretty easy to make at home and require minimal supervision – make them up and then let them ferment. it's pretty simple.

Fermented foods are getting an excellent reputation for supporting various aspects of your immune and digestive system and even reduce sugar addiction and improve your mood [23]. Fermented cod liver oil is also rich in vitamins such as fat-soluble A, D, E, and K, and omega-3 fatty acids.
