Foods That Support a Healthy Gut

1. Yogurt

Yogurt is widely recognized for its probiotic properties, making it a staple food for supporting gut health. Probiotics are live microorganisms that, when consumed in adequate amounts, confer health benefits by enriching the natural microbial community in the gut. The fermentation process used to make yogurt involves specific bacterial strains—most commonly Lactobacillus bulgaricus and Streptococcus thermophilus—which help break down lactose and enhance nutrient absorption. This process not only imparts yogurt’s characteristic tangy flavor but also populates it with beneficial bacteria that can aid digestion and bolster the immune system (source).

Compared to other fermented foods such as kefir, sauerkraut, and kimchi, yogurt is unique because it is both highly palatable and widely available. While kefir contains a greater diversity of probiotic strains, yogurt remains a convenient and familiar option for many people.

When choosing yogurt, opt for varieties labeled with “live and active cultures.” Avoid brands with excessive added sugars or artificial flavors, as these can counteract the benefits. Greek yogurt, in particular, offers a creamy, protein-rich option that maintains strong probiotic content. Look for ingredient lists that specify probiotic strains, ensuring maximum gut health benefits.

2. Kefir

Kefir is a fermented dairy beverage known for its pronounced probiotic content and unique fermentation process. Unlike yogurt, which is typically fermented with just two bacterial strains, kefir is made by adding kefir “grains”—a blend of bacteria and yeast—to milk. These grains initiate fermentation, resulting in a tangy, slightly effervescent drink packed with a diverse array of beneficial microorganisms, including Lactobacillus, Bifidobacterium, and various yeasts (source).

When compared to yogurt, kefir generally contains a broader spectrum of probiotic species, which may provide enhanced benefits for gut health. Its thinner consistency makes it more suitable as a drink, while yogurt is often eaten with a spoon. Additionally, kefir tends to be better tolerated by people with lactose intolerance due to the presence of specific enzymes that help break down lactose during fermentation.

Incorporating kefir into daily meals is easy and versatile. Try pouring kefir over granola or muesli for a probiotic-rich breakfast. It also blends seamlessly into smoothies, adding a creamy texture and a nutritional boost. For a simple snack, enjoy plain kefir with a drizzle of honey or a handful of fresh berries.

3. Sauerkraut

Sauerkraut is a traditional fermented food made from finely shredded cabbage and salt. Its fermentation process relies on naturally occurring lactic acid bacteria, which break down the sugars in cabbage and produce an acidic environment that encourages the growth of beneficial microbes. These probiotics help populate the gut microbiota, supporting digestion and potentially enhancing immune function (source). Regular consumption of sauerkraut can contribute to a diverse microbiome, which is associated with improved gut health and resilience against harmful bacteria.

In contrast, raw cabbage—while high in fiber, antioxidants, and vitamins—does not contain significant amounts of live probiotics. The fermentation process transforms cabbage into a gut-friendly superfood by introducing and multiplying beneficial bacteria. Although both raw and fermented cabbage offer health benefits, only sauerkraut provides the live cultures needed for optimal gut support.

When shopping for sauerkraut, it’s important to choose unpasteurized varieties. Pasteurization, a heat treatment used to extend shelf life, destroys most of the live probiotic cultures. Look for labels indicating “raw,” “unpasteurized,” or “contains live cultures.” These products are typically found in the refrigerated section and retain the active microorganisms essential for gut health.

4. Kimchi

Kimchi, a staple in Korean cuisine, is a fermented vegetable dish most commonly made from napa cabbage, radishes, and a variety of seasonings. Its fermentation process is driven by lactic acid bacteria, particularly Lactobacillus kimchii, Leuconostoc, and Weissella species (source). These probiotic strains help support a healthy gut by enhancing microbial diversity, improving digestion, and boosting immune function. Kimchi’s fermentation also produces bioactive compounds such as vitamins, antioxidants, and anti-inflammatory agents, all of which contribute to its health-promoting properties.

Compared to other Korean side dishes like pickled radishes (danmuji) or non-fermented salads, kimchi stands out due to its high probiotic content and complex flavor profile. While pickled foods may offer some benefits, only fermented dishes like kimchi provide live cultures that foster a thriving gut microbiome. Traditional Korean meals often include a variety of banchan (side dishes), but kimchi remains the most potent source of probiotics among them.

To add kimchi to your diet, try mixing it into rice bowls, serving it alongside grilled meats, or incorporating it into scrambled eggs for a savory twist. Its tangy, spicy flavor also pairs well with soups, stews, and sandwiches, offering both taste and gut health benefits.

5. Miso

Miso is a Japanese fermented soybean paste known for its savory umami flavor and positive effects on gut health. The fermentation process involves inoculating soybeans (and sometimes rice or barley) with the fungus Aspergillus oryzae, along with beneficial bacteria and yeasts. This lengthy fermentation, which can last from a few months to several years, generates a complex mixture of enzymes and live microorganisms that can help balance gut flora and enhance digestion (source). These probiotic cultures, especially the lactic acid bacteria, contribute to a diverse and resilient microbiome.

It is important to distinguish between traditional miso and instant miso soup packets. While fresh miso paste contains live cultures that benefit gut health, most commercial soup packets use pasteurized miso or add artificial flavorings, which destroy or omit these probiotics. As a result, instant miso soups typically do not provide the same gut-supporting benefits as fresh miso paste.

For optimal results, use unpasteurized miso paste found in the refrigerated section of grocery stores. Add the paste to warm (not boiling) water to preserve the live cultures. Miso can enhance soups, marinades, dressings, and sauces, introducing both flavor and probiotics to your meals.

6. Tempeh

Tempeh is a traditional Indonesian food made from fermented soybeans pressed into a firm, cake-like form. The fermentation process uses the mold Rhizopus oligosporus, which binds the soybeans together and breaks down compounds that can inhibit digestion. This not only enhances the nutritional value and digestibility of soybeans but also introduces beneficial microorganisms that can support a healthy gut microbiome (source). Additionally, tempeh is a rich source of protein, fiber, vitamins, and minerals, making it a nutritious plant-based option.

Compared to tofu, which is made by coagulating soy milk and lacks fermentation, tempeh offers greater benefits for gut health due to its live cultures and higher fiber content. While tofu has a milder taste and softer texture, tempeh is dense, nutty, and slightly earthy, thanks to the fermentation process. Tofu is generally easier to digest for some people, but tempeh’s probiotic content and whole-bean composition make it particularly valuable for gut support.

Tempeh is highly versatile in the kitchen. It can be sliced, marinated, and grilled, crumbled into stir-fries or salads, or pan-fried for a crisp texture. Try adding tempeh to sandwiches, Buddha bowls, or curries to enrich your meals with both flavor and probiotics.

7. Kombucha

Kombucha is a fizzy, tangy beverage made by fermenting sweetened tea with a symbiotic culture of bacteria and yeast, known as a SCOBY. This culture transforms sugar into organic acids, B vitamins, and a variety of probiotic strains, which can help promote the growth of beneficial gut microbes and potentially enhance digestive health (source). The resulting drink is rich in antioxidants and contains trace amounts of alcohol produced during fermentation.

There are differences between commercial and homemade kombucha. Commercial options often undergo pasteurization to prolong shelf life, which can reduce or eliminate the live probiotic content. Some brands add sweeteners, juices, or artificial flavorings, impacting both nutritional quality and gut health benefits. Homemade kombucha, in contrast, typically retains more live cultures due to the absence of pasteurization, but it must be prepared carefully to avoid contamination.

When selecting kombucha, look for raw, unpasteurized varieties that specify “live and active cultures” on the label. High-quality kombucha should be slightly cloudy, with natural sediment at the bottom—a sign of active fermentation. Avoid excessively sweet brands and choose those with simple, natural ingredients for the best probiotic potential.

8. Pickles (Fermented)

Fermented pickles are cucumbers preserved through the natural action of lactic acid bacteria, rather than by vinegar brining. During fermentation, salt and water create a brine in which beneficial bacteria thrive, converting sugars into lactic acid. This not only gives fermented pickles their distinctive tang but also populates them with probiotics that can enhance gut flora and aid digestion (source). In contrast, vinegar-brined pickles are made by soaking cucumbers in vinegar, which preserves them but prevents the growth of probiotic bacteria, offering none of the gut health benefits associated with fermentation.

Many other vegetables, such as carrots, beets, and green beans, can also be fermented using a similar brining method. While all pickled vegetables provide flavor and crunch, only those that undergo natural fermentation offer live bacterial cultures. Vinegar-based pickled products, though tasty and shelf-stable, do not support gut health in the same way as their fermented counterparts.

When sourcing fermented pickles, seek out products labeled “naturally fermented,” “raw,” or “contains live cultures.” These are usually found in the refrigerated section rather than on regular grocery shelves. Homemade versions are also an option, allowing you to control ingredients and maximize probiotic content.

9. Sourdough Bread

Sourdough bread is made using a natural fermentation process involving wild yeast and lactic acid bacteria, which develop from a starter of flour and water. This fermentation breaks down gluten and phytic acid, making nutrients more available and the bread easier to digest. The lactic acid bacteria produce organic acids that give sourdough its signature tangy flavor and contribute beneficial compounds that may support gut health (source). While most of the live cultures are lost during baking, their fermentation byproducts and prebiotic fibers can still encourage the growth of healthy gut bacteria.

In contrast, regular commercial bread is typically made with baker’s yeast and lacks the extended fermentation that enriches sourdough with unique flavors and nutrients. Standard breads can also contain additives and preservatives that may not be as gut-friendly. Sourdough’s slow fermentation process, however, produces a more wholesome loaf with complex carbohydrates that are less likely to cause digestive discomfort.

When selecting sourdough bread, look for loaves made with minimal ingredients: flour, water, salt, and starter. Artisanal or bakery sourdoughs are more likely to be traditionally fermented, whereas some supermarket “sourdough” breads may simply use flavoring agents. Always check labels for authenticity and quality.

10. Natto

Natto is a traditional Japanese food made by fermenting soybeans with the bacterium Bacillus subtilis var. natto. This unique fermentation process yields a sticky, stringy texture and a strong, distinctive aroma. Natto is renowned for its exceptionally high probiotic content, particularly the Bacillus subtilis strain, which can survive the harsh environment of the digestive tract and colonize the gut, promoting a balanced microbiome and improved digestion (source). Additionally, natto contains nattokinase, an enzyme associated with heart health and anti-inflammatory benefits.

Compared to other soy products like tofu and edamame, natto stands out for its fermentation and probiotic density. Tofu is made by coagulating soy milk and does not undergo fermentation, while edamame are simply boiled soybeans. Neither tofu nor edamame provides the live cultures found in natto, making natto a superior choice for gut health among soy-based foods.

For beginners, natto’s strong flavor and texture can be an acquired taste. To ease into it, try mixing natto with a small amount of soy sauce, mustard, or green onions. Serve it over steamed rice, blend it into sushi rolls, or add it to salads for a unique, probiotic-rich meal.

11. Bananas

Bananas are a widely consumed fruit that serve as an excellent source of prebiotics—non-digestible fibers that nourish beneficial gut bacteria. Bananas, particularly when slightly underripe, are rich in resistant starch and inulin, which pass through the digestive tract intact and become food for probiotic organisms in the colon (source). Supporting the growth of healthy microbiota, these prebiotics can improve gut motility, nutrient absorption, and overall digestive comfort.

Compared to other fruits, bananas possess a higher concentration of prebiotic fibers, especially when compared to ripe bananas or fruits like apples and oranges. While many fruits provide dietary fiber and antioxidants, bananas stand out for their specific prebiotic profile. Other fruits such as kiwifruit and berries also offer some prebiotic benefits, but bananas are particularly convenient and affordable for daily consumption.

Integrating bananas into snacks is simple and versatile. Enjoy them sliced on whole-grain toast with nut butter, blended into smoothies, or as a topping for oatmeal and yogurt. For a grab-and-go option, bananas pair well with a handful of nuts or dark chocolate. Frozen banana slices also make a creamy base for homemade “nice cream” desserts.

12. Onions

Onions are a potent prebiotic food due to their high content of inulin, a type of soluble fiber that nourishes beneficial gut bacteria. Inulin passes through the digestive tract without being absorbed, serving as a food source for probiotics, which in turn help maintain a balanced gut microbiome and support immune function (source). The natural sulfur compounds in onions also contribute to their health-promoting properties, including antioxidant effects and the potential to reduce inflammation.

The prebiotic value of onions is present in both raw and cooked forms, but raw onions tend to retain higher levels of inulin and certain antioxidants. Cooking onions softens their flavor and makes them easier to digest for some people, though it can slightly decrease their inulin content. Both forms, however, still offer notable gut health benefits, so variety in preparation is encouraged.

To incorporate onions for gut health, add raw slices to salads, salsas, or sandwiches. Cooked onions can be sautéed as a flavorful base for soups, stews, and stir-fries, or caramelized and added to grain bowls, omelets, or roasted vegetables. Including onions regularly in meals is an easy and tasty way to boost prebiotic intake.

13. Garlic

Garlic is celebrated for its rich content of prebiotic compounds, particularly inulin and fructooligosaccharides (FOS), which selectively nourish beneficial gut bacteria such as Bifidobacteria and Lactobacilli. These prebiotic fibers pass through the digestive system undigested, reaching the colon where they stimulate the growth and activity of health-promoting microbes (source). Additionally, garlic contains sulfur-based compounds like allicin, which provide antioxidant and antimicrobial benefits, further supporting gut and immune health.

While garlic supplements are available and may offer some health benefits, they often lack the full spectrum of prebiotic fibers and bioactive compounds present in fresh garlic. Many supplements are standardized for allicin but contain little or no inulin, diminishing their gut-nourishing effects. Consuming whole garlic ensures a more comprehensive intake of both prebiotic and antioxidant components.

To maximize garlic’s gut health benefits, use it raw or lightly cooked. Crushing or chopping garlic cloves and allowing them to sit for 10 minutes before use enhances the formation of beneficial allicin. Add raw garlic to salad dressings, dips, or salsas, or stir into cooked dishes just before serving to preserve its beneficial compounds and prebiotic content.

14. Asparagus

Asparagus is a nutrient-dense vegetable and an excellent source of prebiotics, particularly inulin. Inulin is a type of dietary fiber that passes through the digestive system undigested and serves as nourishment for beneficial gut bacteria. By promoting the growth of probiotics such as Bifidobacteria, asparagus helps support digestive health, improve nutrient absorption, and enhance immune function (source). Additionally, asparagus is rich in antioxidants, vitamins A, C, and K, and folate, contributing to overall wellness.

Both raw and cooked asparagus offer prebiotic benefits, though raw asparagus contains slightly higher levels of inulin. Cooking asparagus, whether by steaming, roasting, or grilling, softens the stalks and makes them more palatable and digestible for most people. While some of the heat-sensitive nutrients may be reduced during cooking, the prebiotic fiber remains intact, ensuring continued support for gut microbiota.

Adding asparagus to meals is simple and versatile. Chop raw asparagus spears and toss them into salads for a crunchy, fresh addition. Lightly roast or grill asparagus as a side dish, include it in stir-fries, pasta, or risotto, or blend cooked asparagus into soups for a creamy, fiber-rich boost to your diet.

15. Leeks

Leeks are a member of the allium family, closely related to onions and garlic, and are valued for their high prebiotic fiber content, particularly inulin. This fiber passes undigested into the colon, where it selectively feeds beneficial gut bacteria such as Bifidobacteria and Lactobacilli, helping to enhance microbial diversity and overall gut health (source). Regular consumption of leeks may contribute to improved digestion, increased nutrient absorption, and a stronger immune system.

While both leeks and onions offer prebiotic benefits, leeks tend to have a milder, sweeter flavor and a more tender texture. They are less pungent than raw onions, making them ideal for a wider range of palates and culinary applications. Leeks also contain a slightly higher concentration of inulin compared to onions, making them a particularly potent source of prebiotics within the allium family.

Leeks can be incorporated into various recipes to boost gut health. Add sliced leeks to soups, stews, or broths for a mellow, savory base. Try sautéing leeks with olive oil and herbs as a side dish, mixing them into quiches, or roasting them alongside other root vegetables. Their subtle flavor blends seamlessly with many dishes.

16. Jerusalem Artichoke

Jerusalem artichoke, also known as sunchoke, is a knobby root vegetable celebrated for its exceptionally high inulin content. Inulin is a type of prebiotic fiber that bypasses digestion in the upper gastrointestinal tract, reaching the colon where it feeds beneficial bacteria such as Bifidobacteria (source). This process supports a balanced gut microbiome, improves mineral absorption, and may enhance digestive regularity. Jerusalem artichokes are also rich in potassium, iron, and vitamin C, making them a nutrient-dense addition to the diet.

Compared to other root vegetables like potatoes, carrots, or beets, Jerusalem artichokes stand out for their inulin content. While most root vegetables provide dietary fiber and antioxidants, few deliver prebiotics in such concentrated amounts. This makes Jerusalem artichoke one of the most effective vegetables for specifically nurturing gut health.

Jerusalem artichokes can be enjoyed raw or cooked. When raw, they have a crisp texture and a mildly nutty, sweet flavor—try slicing them thin and adding to salads or slaws. When cooked, they become tender and creamy; roast, sauté, or blend them into soups and purees. Scrub thoroughly before using, as their skin is edible and contains fiber.

17. Chicory Root

Chicory root is renowned for its exceptionally high inulin content, a soluble prebiotic fiber that can make up to 65% of its weight. Inulin from chicory root passes undigested through the stomach and small intestine, reaching the colon where it stimulates the growth of beneficial gut bacteria such as Bifidobacteria and Lactobacilli (source). Regular consumption of chicory root can help improve digestive health, enhance mineral absorption, and contribute to a feeling of fullness that supports weight management.

Chicory root is commonly used as a coffee substitute due to its robust, slightly bitter flavor and caffeine-free profile. Unlike regular coffee, which does not offer prebiotic benefits, chicory root beverages can support gut health while providing a similar taste experience. Other coffee alternatives, such as roasted barley or dandelion root, may also offer prebiotics, but chicory root remains the highest in inulin.

Chicory root can be utilized in several ways in the kitchen. Brew ground chicory root to make a hot drink on its own or blended with coffee. Add roasted chicory root to baked goods or homemade granola for extra fiber. It is also available as an inulin powder that can be stirred into smoothies or yogurt for a gut-friendly boost.

18. Apples

Apples are an excellent source of pectin, a type of soluble fiber with notable prebiotic properties. Pectin serves as food for beneficial gut bacteria, helping to increase the production of short-chain fatty acids like butyrate, which support colon health and reduce inflammation (source). Regular apple consumption is associated with improved digestion, enhanced microbiome diversity, and greater overall gut resilience. Apples also offer antioxidants and vitamins that further contribute to digestive and general health.

Compared to pears, which also contain soluble fiber and prebiotic compounds, apples tend to have slightly higher concentrations of pectin, especially in the peel. While both fruits are valuable for gut health, apples’ unique fiber profile and widespread availability make them a particularly convenient prebiotic source. Pears, on the other hand, provide more sorbitol, a sugar alcohol that can aid bowel regularity, but may cause discomfort in sensitive individuals.

For gut health, it is best to consume apples with the skin on, as much of the fiber and nutrients are concentrated there. Varieties such as Granny Smith, Fuji, and Braeburn are especially rich in fiber. Include apple slices in salads, oatmeal, or yogurt, or simply enjoy them as a portable, gut-friendly snack.

19. Oats

Oats are a highly nutritious whole grain known for their abundance of beta-glucan, a type of soluble fiber with powerful prebiotic effects. Beta-glucan helps feed beneficial gut bacteria, promoting the production of short-chain fatty acids like butyrate, which support intestinal health and reduce inflammation (source). Regular consumption of oats may contribute to improved digestion, lower cholesterol, and enhanced immune function, making them a staple for those seeking to support their gut microbiota.

It’s important to differentiate between whole or steel-cut oats and instant oats. Whole and steel-cut oats are less processed, retain more of their fiber and nutrients, and provide a slower, more sustained energy release. Instant oats, on the other hand, are pre-cooked, often flavored, and may contain added sugars or preservatives, resulting in diminished prebiotic and nutritional value. For optimal gut health, choose minimally processed oats.

Oats are incredibly versatile for breakfast. Enjoy them as classic oatmeal topped with fresh fruit, nuts, and seeds, or prepare overnight oats by soaking them in milk or yogurt with berries. Oats can also be added to smoothies, baked into muffins, or made into homemade granola for a tasty and gut-friendly start to the day.

20. Barley

Barley is a whole grain renowned for its high content of prebiotic fibers, particularly beta-glucan and arabinoxylan. These fibers pass through the digestive system undigested, serving as a food source for beneficial gut bacteria and promoting the production of short-chain fatty acids that support colon health and reduce inflammation (source). Regular inclusion of barley in the diet has been linked to improved digestion, enhanced microbiome diversity, and better blood sugar regulation.

Compared to wheat, barley offers a higher concentration of soluble prebiotic fibers, particularly in its whole grain and hulled forms. While wheat also contains dietary fiber, much of it is insoluble, and refined wheat products lose significant amounts of their fiber during processing. Barley’s beta-glucan content gives it a unique advantage for nurturing gut health and supporting heart health simultaneously.

Barley can be incorporated into meals in a variety of ways. Use pearl or hulled barley as a base for hearty soups and stews, add cooked barley to salads for a chewy texture, or substitute it for rice in grain bowls. Barley flour can also be used in baking breads, muffins, and crackers to increase the fiber content of homemade goods.

21. Lentils

Lentils are a nutrient-dense legume, celebrated for their rich content of soluble fiber, particularly prebiotic types such as resistant starch and oligosaccharides. These fibers travel through the digestive tract largely intact, providing nourishment for beneficial gut bacteria and supporting the production of short-chain fatty acids like butyrate, which help maintain a healthy colon and reduce inflammation (source). Lentils are also an excellent source of plant-based protein, iron, and folate, making them a valuable addition to a balanced diet.

When compared to beans, lentils have a slightly different fiber profile and tend to be easier to digest for many individuals. While beans such as black beans, kidney beans, and chickpeas also provide prebiotic fibers and nutrients, they often contain more insoluble fiber and can cause more digestive discomfort or bloating for some people. Lentils cook faster, have a milder flavor, and are less likely to cause gastrointestinal issues, making them a gentler option for those looking to boost gut health.

Lentils are versatile and easy to incorporate into everyday meals. Try them in soups, stews, or curries, toss cooked lentils into salads, or use them as a base for veggie burgers. Red, green, and brown lentils all offer gut-friendly benefits and adapt well to a variety of cuisines.

22. Beans

Beans, including varieties such as black beans, kidney beans, pinto beans, navy beans, and chickpeas, are excellent sources of both soluble and insoluble fiber. Their rich fiber content, including prebiotic oligosaccharides, passes through the digestive tract to feed beneficial gut bacteria, fostering increased microbial diversity and the production of short-chain fatty acids that help maintain a healthy colon and reduce inflammation (source). Beans also offer protein, iron, magnesium, and other nutrients, making them a staple food for overall health and digestion.

While both beans and lentils support gut flora, beans generally contain higher amounts of insoluble fiber and oligosaccharides, which can result in more digestive gas for some people. Lentils tend to be easier to digest and cook more quickly, but beans offer greater variety in flavor, color, and texture. Including a mix of both in the diet ensures a broader spectrum of gut-nourishing nutrients and fibers.

To maximize the gut health benefits of beans while minimizing digestive discomfort, soak dried beans overnight, discard the soaking water, and cook them thoroughly. Adding herbs such as bay leaves or cumin can help reduce gas. Use beans in chili, salads, burritos, or blended into dips like hummus for a versatile, fiber-rich boost.

23. Almonds

Almonds are a nutrient-dense nut that provides a unique combination of prebiotic fiber, healthy fats, and polyphenols—all of which support the growth of beneficial gut microbes. The skin of almonds is particularly rich in fiber and antioxidants, which serve as fuel for Bifidobacteria and Lactobacillus species in the colon, promoting increased microbial diversity and improved digestive health (source). Regular almond consumption has also been associated with enhanced gut barrier function and reduced markers of inflammation.

When comparing raw and roasted almonds, both offer gut health benefits, but raw almonds tend to retain slightly higher levels of prebiotic fiber and heat-sensitive nutrients. Roasting can alter the flavor and texture, making almonds crunchier and more flavorful, but may reduce some antioxidant content. However, as long as they are unsalted and minimally processed, both raw and dry-roasted almonds are gut-friendly snacks. Avoid almonds with added sugars or excessive salt, as these can negate some health benefits.

Almonds are easy to incorporate into snacks and meals. Enjoy a handful on their own, mix into homemade trail mix, sprinkle sliced almonds over yogurt or oatmeal, or blend into smoothies. Almond butter is another versatile option, perfect as a spread or dip for fruit and vegetables.

24. Walnuts

Walnuts are distinguished among nuts for their high content of polyphenols, particularly ellagitannins, which are metabolized in the gut to produce beneficial compounds called urolithins. These polyphenols, along with walnut’s fiber and alpha-linolenic acid (a plant-based omega-3 fatty acid), have been shown to promote the growth of beneficial gut bacteria such as Lactobacillus and Bifidobacteria (source). Regular walnut consumption has been linked to greater microbial diversity, improved gut barrier function, and reduced inflammation throughout the digestive tract.

Compared to other nuts like almonds, cashews, or hazelnuts, walnuts provide a unique profile of polyunsaturated fats and polyphenols, making them particularly effective at modulating the gut microbiome. While all nuts contribute fiber and healthy fats, walnuts stand out for their ability to support both cardiovascular and gut health through their unique bioactive compounds.

To preserve the delicate fats and antioxidants in walnuts, store them in an airtight container in the refrigerator or freezer, especially after opening.

25. Flaxseeds

Flaxseeds are a powerful superfood for gut health, thanks to their high content of both soluble and insoluble fiber, as well as plant-based omega-3 fatty acids (alpha-linolenic acid). The fiber in flaxseeds acts as a prebiotic, fueling the growth of beneficial gut bacteria and promoting regular bowel movements (source). Additionally, the omega-3s in flaxseeds have anti-inflammatory properties that may help support gut barrier function and reduce the risk of digestive disorders.

When it comes to maximizing health benefits, ground flaxseeds are superior to whole seeds. The tough outer shell of whole flaxseeds is difficult for the body to break down, meaning most of their nutrients—including omega-3s and fiber—pass through undigested. Ground flaxseeds, on the other hand, offer greater bioavailability and allow the nutrients to be absorbed and utilized by the body.

For daily gut health support, add one to two tablespoons of ground flaxseeds to your diet. Stir them into oatmeal, yogurt, smoothies, or pancake batter, or sprinkle over salads and cereals. Store ground flaxseeds in the refrigerator in a sealed container to preserve their healthy fats and prevent rancidity.

26. Chia Seeds

Chia seeds are renowned for their impressive soluble fiber content, which enables them to absorb many times their weight in liquid and form a gel-like consistency. This gel formation slows digestion, promotes a feeling of fullness, and acts as a prebiotic by nourishing beneficial gut bacteria (source). The mucilaginous gel also helps to soften stool and support healthy bowel movements, making chia seeds an excellent addition to a gut-friendly diet. Chia seeds are also rich in plant-based omega-3 fatty acids, antioxidants, and essential minerals such as calcium and magnesium.

When compared to flaxseeds, chia seeds offer a similar nutrient profile, including fiber and omega-3s. However, the unique gel-forming property of chia makes it particularly beneficial for digestive health, as it can help regulate transit time and support a healthy gut environment. Unlike flaxseeds, chia seeds do not need to be ground for their nutrients to be absorbed, making them convenient to use whole.

Chia seeds are highly versatile in meals. Stir them into yogurt, oats, or smoothies, or use them to make chia pudding by soaking them in milk or plant-based alternatives. They can also be added to baked goods, sprinkled on salads, or used as a thickener in jams and sauces.

27. Kiwi

Kiwi is a nutrient-rich tropical fruit celebrated for its unique combination of dietary fiber and the enzyme actinidin. Actinidin aids in the breakdown of protein during digestion, supporting efficient nutrient absorption and promoting regular bowel movements (source).
