Health Benefits of Bananas
Here are a few things you might experience when you eat a banana every day.
You May Increase Your Energy
Bananas are a good source of carbs—your body’s primary fuel for energy production, according to 2022 research published in theInternational Journal of Food Properties. Bananas also contain B vitamins, such as vitamins B1, B3 and B6, which are essential for your body’s energy production system to work, according to 2020 research published inNutrients.
Bananas can be part of a healthy meal or snack and are best utilized when paired withhealthy fatsand/or protein. This is because carbohydrates digest more quickly than protein or fat, so when eaten alone, they can send your blood sugar soaring—and subsequently crashing. Pairing a banana with a healthy fat or protein—such as a handful of almonds or a cup of Greek yogurt—will help prolong the energy the banana provides and keep your blood sugar more stable.
You May Maintain a Healthy Weight
When eaten as part of a balanced meal, bananas can help keep you satisfied longer. Feeling satisfied between meals reduces the likelihood that you’ll have cravings and exceed your daily caloric needs—which over time, can contribute to weight gain.
While there is no evidence that bananas directly contribute to weight loss, they are a convenient and readily available food option that can be easily incorporated into a nutritious eating pattern to lose weight.
You May Increase Your Fiber Intake
According to the2020-2025 Dietary Guidelines for Americans, more than 90% of women and 97% of men do not get the recommended daily amount of 28 g to 34 g of fiber per day.
Enter the banana.
Medium-sized bananas have about 3 g of fiber each, andfiber has many health benefits, including keeping you full longer.
Pectin, a specific type of fiber found in bananas, can help your body eliminate waste more effectively. As bananas ripen, they tend to lose some of their pectin content, so greener or slightly ripe bananas are a better source of fiber than overripe bananas, per a 2021 study published in the journalPLoS One.
Bananas also contain a type of dietary fiber called resistant starch, whichacts as a prebiotic, giving your beneficial gut bacteria something to nosh on. A healthy gut means lower inflammation, reduced disease risk and better overall health.
You May Improve Your Heart Health
Bananas are known for being a great source of potassium, with one medium banana coming in at 422 milligrams. That’s 9% of your daily recommended intake, per theFDA.
Potassium is found in all body tissues and is essential for normal cell function. It isimportant for a healthy heartas well.The DASH diet, a protocol commonly recommended for people diagnosed with—or at risk for—heart disease, recommends getting potassium from fruits and vegetables. Bananas are a great way to contribute to your daily potassium needs.
Getting enough potassium in your diet may also help lower blood pressure. High blood pressure is one of the leading causes of cardiovascular disease, so eating foods containing potassium each day is an important part of a healthy lifestyle. Fortunately, it’s easy toincorporate bananasinto foods like smoothies and overnight oats—which can also contain other fruits and whole grains that can promote heart health as well.
You May Reduce Your Risk for Chronic Disease
A lesser-known fact about bananas is that they are rich in compounds that have antioxidant properties, according to 2022 research in theInternational Journal of Food Properties.
According to 2022 research published inFood Science & Nutrition, bananas contain many antioxidants that may have anticancer potential, specifically for pancreatic cancer and triple-negative breast cancer.
Oxidative stress can cause inflammation and damage body tissues. If this continues as you age, it can lead tochronic inflammation—a known driver of diseases such as heart disease, diabetes, cancer and more.
Consuming fruits and vegetables high in antioxidants—like bananas—can help provide your body with the tools to help keep inflammation at bay.
According to theUSDA, one medium banana contains:
How Many Bananas Should You Eat per Day?
Now that you know bananas are nothing to fear, how many should you eat? While there’s no blanket rule, sticking to one to two bananas per day shouldn’t cause issues for most people. With that said, remember that they are relatively high in carbohydrates, so eating them along with protein or fat is also advisable to support stable energy levels.
People with chronic kidney disease should limit bananas and other foods that are high in potassium to protect their kidneys and heart from damage, according to theNational Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
Eating too many bananas orother high-potassium foodscan cause excess potassium in the body, also calledhyperkalemia. This can cause serious health problems, including heart issues. While most people wouldn’t be able to stomach the number of bananas necessary to cause this to happen, it’s something to be mindful of.
Bananas are best consumed in moderation and as part of a healthy, balanced eating pattern, much like other healthy foods.
