5 unexpected foods that are good for your gut

Your gut microbes thrive on a variety of foods—and some aren’t what you’d expect. These five surprising picks deliver fiber, probiotics, and other gut-loving nutrients to support digestion and microbial diversity.

Cooked and cooled potatoes pack “resistant starch,” a type of fiber that avoids digestion in your small intestine, making it fuel for gut bacteria and helping regulate digestion.

You probably think of yogurt when you think gut health—but sauerkraut and onions also feed healthy gut bacteria. They're rich in probiotics and prebiotic fibers that support digestion.

Whole-grain bread isn't just convenient—it's rich in fiber, which helps maintain healthy bowel movements and supports beneficial gut flora over the long term.

Fermented staples like miso or — believe it or not — certain cheeses bring beneficial bacteria to your gut without the typical stereotypes.

Fruits you might overlook—like apples, raspberries, or even bananas—are great sources of fiber. They feed your microbiome and keep your digestive system on track.
