How to incorporate fermented foods into your diet

Here are some simple ways to incorporate fermented foods into your daily routine.

4 ideas for incorporating fermented foods into your daily routine

1. Utilize fermented seasonings

Fermented seasonings such as miso, soy sauce, and vinegar are prime examples of easily incorporated fermented foods. Simply adding them to your everyday cooking can support your gut health. However, some are high in salt, so be sure to consume them in moderation.

2. Replace staple foods with ingredients that promote fermentation.

By choosing glutinous barley, brown rice, or whole-wheat bread and pasta instead of refined white rice and wheat flour, you can get plenty of dietary fiber that aids in gut fermentation. Combining these with fermented foods makes them even more effective for improving gut health.

3. Consume fermented foods in a balanced way.

Fermented foods such as natto, kimchi, pickles, and yogurt each contain different types of beneficial bacteria. By eating small amounts of each daily, you can introduce a variety of bacteria to your gut and improve your intestinal environment.

4. Incorporate amazake or shio koji into your cooking.

Amazake, sometimes called a "drinkable IV drip," is rich in vitamins and amino acids, making it perfect for a morning energy boost. Shio koji enhances the flavor of dishes, allowing you to utilize the power of fermentation while keeping salt content low. It's also recommended for dressings and pickles.
