Here are the 3 best foods you can add to help out your gut.
1. Fermented Foods
The first type of foods are fermented foods where the microbes are still alive. These are foods like sauerkraut, miso, tempeh, or kombucha.

The biggest benefit comes from live cultures, so many processed store-bought varieties won't work the same.

2. Leafy Greens
The second type is leafy greens like lettuce, microgreens, or kale. These plants don't contain the living cultures, but they are high in prebiotic fibers and polyphenols which are both essentially food for your gut biome.

3. Legumes
The third foods are legumes like beans, lentils, or chickpeas. These are high in resistant starch and fermentable fiber which means your body will ferment these fibers for you inside the colon.

Fermented foods act like probiotics, while leafy greens and legumes act as prebiotics — together they support a healthy gut microbiome.
