Your gut is home to trillions of bacteria that affect digestion, immunity, and even mood. Keeping that balance in check is key, and probiotics—live, beneficial bacteria—help keep your microbiome thriving.

While supplements are an option, the best way to get probiotics is through food. From tangy ferments to creamy dairy, these delicious probiotic-rich options can support your gut health naturally.

Here are 18 foods that nutritionists swear by for a happy, balanced digestive system.

1. Greek Yogurt

Greek yogurt is one of the most well-known probiotic foods, packed with live cultures that help balance gut bacteria. It’s also rich in protein, calcium, and vitamins, making it a nutritious addition to your diet.

Choose plain, unsweetened varieties to avoid excess sugar, and look for labels that say “live and active cultures” to ensure you’re getting the good stuff.

2. Kefir

Kefir is a fermented milk drink that’s even more potent than yogurt when it comes to probiotics. It contains a diverse mix of bacteria and yeast, making it a powerhouse for gut health.

Kefir is slightly tangy, creamy, and easy to blend into smoothies or enjoy on its own. Plus, it’s often tolerated better by those who are lactose-sensitive.

This crunchy, tangy fermented cabbage is a classic probiotic food. Loaded with gut-friendly bacteria, sauerkraut also provides fiber, vitamin C, and antioxidants.

To get the probiotic benefits, choose raw, unpasteurized sauerkraut from the refrigerated section, as pasteurization kills the beneficial bacteria.

4. Kimchi

Kimchi, Korea’s famous fermented cabbage dish, is packed with probiotics, vitamins, and spicy goodness. Made with chili, garlic, ginger, and other seasonings, it supports digestion while adding bold flavor to meals.

It also contains prebiotics, which feed the beneficial bacteria in your gut, making it a double win for gut health.

5. Miso

A staple in Japanese cuisine, miso is a fermented soybean paste used in soups, dressings, and marinades. It’s loaded with probiotics, enzymes, and essential nutrients like B vitamins and antioxidants.

Since heat can destroy probiotics, adding miso to warm (not boiling) water preserves its gut-boosting benefits.

8. Pickles (Fermented)
