Gut health<\/a> is the gift the internet keeps on giving. Attention to it peaked in the 2010s and never faded. But what does \u201cgut health\u201d even mean?<\/p>\n

\u201cGut health refers to how well the digestive system performs its many jobs, including digesting and absorbing nutrients, moving food through the intestines, maintaining a protective intestinal barrier and supporting a functioning community of gut microorganisms,\u201d explains Johannah Katz, RD<\/a>, a registered dietitian.<\/p>\n

When you have \u201cgood gut health,\u201d Katz says you\u2019ll generally have comfortable digestion and reasonably regular poops. You won\u2019t experience frequent pain, severe bloating<\/a>, constipation<\/a> or diarrhea. But achieving a healthy digestive system is a bit of a personalized endeavor.<\/p>\n

\u201cThere is no single \u2018perfect\u2019 gut microbiome because microbiomes vary considerably<\/a> among healthy people,\u201d she explains.<\/p>\n

So, while your feed is likely full of foods and supplements that reportedly support your digestive system, Katz notes that diet is not one-size-fits-all. Plus, in a world of supplements, understanding the effects of whole foods like bananas<\/a> on your gut health is vital.<\/p>\n

\u201cWhat we eat can influence bowel regularity, digestive symptoms, the intestinal barrier and the activity of the microorganisms living in the gut,\u201d she says. \u201cUnderstanding these effects can help people identify foods that support comfortable digestion while recognizing that the same food may affect two people differently.\u201d<\/p>\n

With that in mind, you may wonder, \u201cDo bananas belong in my gut-friendly diet?\u201d It\u2019s not too black-and-white (or green-and-yellow).<\/p>\n

\u201cOne person may find bananas helpful for regularity, while someone with a sensitive digestive system may experience gas or bloating,\u201d Katz says.<\/p>\n

Katz and two other registered dietitians shared exactly what happens to your gut health when you eat bananas, and why it varies from person to person. Scroll on to learn whether you should go bananas with bananas for gut health. <\/p>\n

Are Bananas Good for Gut Health?<\/p>\n

Three registered dietitians agree that bananas are a great addition to a gut-healthy diet for many people. But you\u2019ll notice the most benefits if you eat bananas daily (or many times weekly) for several months or years.<\/p>\n

\u201cDietary changes can alter the gut microbiome within days, although long-term eating patterns are more important than any single meal or food,\u201d Katz explains.<\/p>\n

Still, your digestive system may give you some near instant gratification after just one banana. Within hours of eating a banana, you may notice less heartburn. \u201cEating bananas aids in mucus production, which can protect your stomach lining,\u201d says Julia\u00a0Zumpano, RD<\/a>, a registered dietitian with Cleveland Clinic.<\/p>\n

Also, you may quickly notice that your poop problems (constipation or loose stools) start to improve, but it depends on the ripeness.<\/p>\n

\u201cWhen unripe, resistant starch in bananas helps bind stools and slows their movement through the digestive tract,\u201d says Malina Malkani, MS, RDN, CDN, LDN<\/a>, a nutrition expert and the owner of\u00a0Malina Malkani Nutrition<\/a> and the author of\u00a0Safe and Simple Food Allergy Prevention<\/a>. <\/p>\n

This benefit can make unripe bananas useful for diarrhea. On the other hand, Malkani explains that the soluble fiber<\/a> in ripe bananas absorbs water, softening stools so they can move through the intestines, potentially soothing constipation.<\/p>\n

Both unripe and ripe bananas contain a type of prebiotic fiber called pectin (green\/unripe bananas have more<\/a>). Your body actually cannot digest prebiotic fiber, so she says it fuels friendly bacteria <\/a>in the gut and can promote feelings of fullness, so you may experience fewer cravings (in a day or a couple of weeks of consistently eating bananas) and weight loss or maintenance (over several weeks or more).<\/p>\n

Over time, you may also notice you get sicker less often and your risk for chronic illness, including some cancers, can go down. You can thank the gut-friendly bacteria. <\/p>\n

\u201cWhen the resistant starch [in unripe bananas] reaches the large intestine, it is fermented by friendly bacteria to produce butyrate, a short-chain fatty acid that promotes gut health<\/a>\u2026 such as helping to protect against disease<\/a>,\u201d Malkani says.<\/p>\n

One of the diseases bananas may help protect against is diabetes, and they may even help improve IBD if you have it.<\/p>\n

\u201cBoth the resistant starch and the pectin in green bananas support better blood sugar control<\/a>, which in turn helps reduce inflammation,\u201d she explains. \u201cWhen it comes to treating and improving digestive conditions like Inflammatory Bowel Disease, lowering inflammation<\/a> is key.\u201d<\/p>\n

If you do have IBD, unripe bananas are generally better tolerated. \u201cWhen unripe, green bananas are considered a low-FODMAP food that can help diversify low-FODMAP diets,\u201d Malkani explains. \u201cAs bananas ripen, the resistant starch is converted to FODMAP sugars.\u201d<\/p>\n

Generally, to see most of the above benefits, Zumpano says it\u2019s sufficient to eat one banana per day. <\/p>\n

Why Do Some Doctors Say Not To Eat Bananas?<\/p>\n

People with conditions like late-stage kidney disease or diabetes<\/a> will want to be mindful of how many, if any, bananas they eat. That being said, Malkani tells Parade that eating a banana per day is safe for most people, but you\u2019ll want to ensure your diet is balanced.<\/p>\n

\u201cHowever, diet diversity is a cornerstone of gut health,\u201d she explains. \u201cFriendly bacteria in the gut need a wide variety of fibers to thrive, and eating the same foods every day, (even generally health-promoting foods like bananas) can sometimes come at the expense of nutritional variety.\u201d<\/p>\n

Also, not everyone\u2019s guts will enjoy the bananas.<\/p>\n

\u201cThe fermentable carbohydrates and resistant starch in bananas may cause gas, bloating or abdominal discomfort in some people, particularly when several bananas or concentrated green-banana products are introduced quickly,\u201d Katz explains. <\/p>\n

Plus, research suggests<\/a> people\u2019s responses to the resistant starch in bananas can vary depending on how much they eat and their existing microbiome. However, you may be able to enjoy a banana at a different level of ripeness.<\/p>\n

\u201cWhen choosing bananas to consume, match the level of ripeness to your own digestive needs,\u201d Malkani suggests. \u201cIf backed up, select bananas that are more ripe. If you are experiencing looser stools, head for the unripe, green bananas.\u201d<\/p>\n

Expert-Backed Ways To Enjoy Bananas<\/p>\n

Since bananas are best consumed as part of a healthy overall diet, we asked registered dietitians to dish their personal favorite ways to enjoy bananas. Here are three ideas they love:<\/p>\n

Banana\u00a0with natural peanut butter. Zumpano is a big fan of this one. \u201cI love the combo of sweet and salty, healthy fat with complex carb,\u201d she raves. \u201cIt\u2019s great for blood sugar control and an energy boost. It\u2019s also a great source of potassium.\u201d<\/p>\n

Greek yogurt with banana, chia seeds<\/a> and walnuts<\/a>. Katz is a fan of the protein in Greek yogurt, which also often contains gut-friendly live cultures. \u201cThe banana and chia seeds provide different types of fiber, while walnuts add unsaturated fats and texture,\u201d she says.<\/p>\n

A smoothie with frozen banana, kefir, berries and spinach. Frozen banana adds sweetness and a creamy texture to a blend of protein and kefir with live cultures. \u201cBerries and spinach add more fiber and plant compounds, making the smoothie more nutritionally diverse than one made only with banana and protein powder,\u201d Katz reports.<\/p>\n
