3 Types of Gut-Healthy Snacks for Better Digestion

"Good digestive health is essential for the body in so many ways, which is why focusing on gut-healthy practices is important, starting with what you're eating," he says. That applies to everything you eat each day, including snacks.
With that in mind, here are three types of snacks that can keep your taste buds and your gut happy.
1. Probiotic-Rich Snacks
Probiotics are the live beneficial bacteria that are the foundation for a strong gut, says Adiana Castro, RDN, a registered dietitian specializing in gut health, and the owner of Compass Nutrition in New York City. These bacteria help balance the gut's community of microorganisms, says Dr. Farhadi.
- Greek yogurt
- Kefir
- Aged cheeses
- Kimchi
- Sauerkraut
- Fermented pickles
"Since heat kills beneficial bacteria, look for products that add the beneficial live bacteria after pasteurization, or that don't undergo pasteurization," Castro says. "For maximum benefit, eat probiotic-rich foods at cold or room temperature rather than cooking them to retain as much of the live bacteria as possible."
While you can also buy supplements that contain probiotics, it's better to get them from food, since then you'll also get the vitamins, minerals, fiber, and other nutrients that support gut health as well, Farhadi says.
2. Prebiotic-Rich Snacks
Some snacks that are naturally rich in prebiotics, says Castro, include:
3. Snacks With Polyphenols
Many of them are concentrated in the skin of fruits and vegetables, but you can get them from a breadth of other food sources as well, she says. Consider polyphenol-packed options like:
- Berries like raspberries, blueberries, blackberries, or strawberries
- Chickpeas
- Edamame
- Nuts like almonds and walnuts
- Dark chocolate
Gut-Healthy Snack Combinations
Using the three main categories above, it's easy to put together snacks that give your gut a boost. "In short, probiotics add to your microbiome, prebiotics feed them, and polyphenols protect them," says Castro. "They work as a team and they are all needed in optimizing and maintaining gut health."
Some ideas, says Castro, include:
- Smoothie with banana, chia seeds, raspberries, and kefir or Greek yogurt
- Overnight oats made with rolled oats, chia seeds, unsweetened cocoa powder, and peanut butter
- Avocado toast with sourdough bread, spinach, and drizzle of olive oil
- Hummus with unpeeled carrots and red bell peppers
- Apple slices with peanut butter
- Trail mix with dark chocolate, nuts, and unsweetened dried fruit
If you're new to adding prebiotics, polyphenols, and probiotics to your eating plan, increase them gradually to let your gut microbes adjust, says Castro. Too much at once could lead to gas and bloating if your body isn’t used to them.
The Takeaway
- Supporting gut health is important for a range of physical and mental functions, particularly for digestive health.
- Snacks rich in probiotics, prebiotics, or polyphenols can help guide your snacking decisions for better gut function.
- Adding these snacks gradually is helpful for preventing bloating or gas that might occur as your gut microbes adjust to these foods.
