Fermented

No, Miso is not keto due to its koji mold content.

What You Need to Know

Miso is a fermented soybean paste that contains koji mold, which contributes to its carbohydrate content. The presence of koji mold makes it unsuitable for a keto diet, which typically restricts carbohydrate intake to maintain ketosis. While miso does offer some health benefits, its sugar and carb levels can hinder the goals of those following a strict ketogenic regimen.

For those on a keto diet, it's essential to avoid miso and opt for alternatives that are low in carbohydrates. Focus on using ingredients such as bone broth, coconut aminos, or other low-carb seasonings to add flavor to your dishes without compromising your dietary goals. Always check nutrition labels to ensure you're staying within your daily carb limits.
