The 7 Best Probiotic Foods for Your Gut (That Aren’t Yogurt)

One of the most astonishing recent health discoveries is how much our gut microbiome impacts our health. But when it comes to growing good gut bacteria you have plenty of delicious probiotic foods to choose from.

Cold potatoes

Cold potatoes—that is, taters that have been washed, cooked, and cooled—are one of the best sources of resistant starch. Resistant starch is a prebiotic, a type of indigestible carbohydrate that acts like food for gut bacteria, encouraging the good bugs to grow and flourish. While resistant starch has many health benefits, one of its most promising aspects is its ability to increase insulin sensitivity, helping people reduce diabetes risk and even lose weight.

Kefir

Think of kefir as yogurt’s tangier but more powerful cousin. The drink is made by seeding milk with kefir “grains,” which are tiny bundles of yeast and bacteria, and letting it sit. Over time the grains ferment the milk, producing a tart drink full of probiotics, or healthy bacteria. A 2013 study found that kefir can help relieve gastrointestinal problems and allergies and may even have a positive effect on heart health. One caveat however: Many commercial kefir drinks contain very high amounts of added sugar, which feeds bad bacteria in your gut, so make sure you read the label and ingredient list. Find out everything you need to know about probiotic before you start taking them.

Green bananas

Most people go out of their way to avoid green bananas but there’s good news for people who just can’t wait until they’re fully ripe. Green bananas are a rich source of prebiotics, particularly resistant starch. They also have a healthy dose of both soluble and insoluble fiber, vitamins, and minerals. The combo provides a feast for good gut bacteria and helps protect your heart and bones. Can’t get past the taste? Try them boiled or fried or sub some green banana flour in place of regular flour.

Kimchi

Don’t let the name throw you—this Korean dish is not only tasty but a health superstar. Kimchi is made by fermenting vegetables with probiotic lactic acid bacteria, which gives it the same boost of healthy bacteria as other fermented foods, like yogurt. Plus, since it’s made from cruciferous veggies like bok choy and cabbage along with healthy spices like garlic and peppers, it provides a mega dose of vitamins, fiber, and antioxidants. One study found that kimchi helps protect against cancer, obesity, and constipation while lowering cholesterol, boosting brain and immune function, and even providing some anti-aging benefits.
