Some have called bananas “nature’s perfect snack,” and it’s easy to see why. The curvy yellow fruits come conveniently packaged, travel well in a lunch bag or purse and are incredibly versatile. They make a great smoothie mixer or a tasty topper on cereal or oatmeal and even have their very own category of (delicious!) muffins and bread.
“Absolutely,” says registered dietitian Elyse Homan, RD, LD. “They’re full of nutrients and easy on the gut. Very few people have problems digesting bananas.”
So, what are you eating when you peel and enjoy? A medium-sized ripe banana contains:
From vitamins to minerals to fiber, bananas are good for you, with lots of nutrition to offer. Plus, they’re easy to digest, reiterates Homan. Here’s a breakdown of banana’s most notable nutritional benefits:
With 3 grams (g) of fiber, a banana supplies nearly 10% of what you need in a day, based on a 2,000-calorie daily diet, according to the U.S. Department of Agriculture (USDA) dietary guidelines.
You hear “fiber” and probably automatically think of digestion. It’s true — fiber is great for your gut. It helps keep things moving in your intestines, and most of us probably need to eat more.
But fiber also impacts your health in other ways. Researchers who looked at data from nearly 200 studies found that people who ate 25 to 29 g of fiber a day had up to a 30% decreased risk of:
Vitamin C (ascorbic acid) is a nutrient that helps your body absorb iron and boosts your immune system’s ability to fight illness. Adults need 75 to 90 milligrams (mg) per day. A banana delivers about 10 mg of vitamin C.
Vitamin C is one of many antioxidants you can get from food. Antioxidants are important because they cancel out free radicals in your body. Free radicals can build up and damage your cells, leading to disease. But antioxidants like vitamin C keep free radicals in check.
Your body needs vitamin B6 for:
“One banana will give you one-quarter to one-third of the vitamin B6 you need in a day,” says Homan.
The USDA recommended daily intake of potassium for adults is 4,700 to 5,000 mg. A banana supplies you with about 422 mg, or a little less than 10% of what you need per day.
Potassium, a mineral, does a lot for your body. It’s essential for the proper function of your:
Getting enough potassium also keeps your blood pressure in a healthy range. Potassium, which lowers blood pressure, balances out sodium, which raises blood pressure.
Homan says potassium also benefits your vascular system — the network of blood vessels and lymph vessels that run through your body’s tissues and organs — and reduces your risk of:
A single medium-sized banana offers about 32 mg of the mineral magnesium, which fulfills around 8% to 10% of your daily magnesium requirement.
Magnesium is involved in many processes in your body, including:
Green, or unripe, bananas are high in resistant starch. “Your body can’t digest resistant starch,” notes Homan. “Instead, it’s a prebiotic that promotes the growth of good bacteria in your colon.” Prebiotics improve digestive health and can be helpful if you’re experiencing diarrhea.
“I often hear patients say they avoid bananas since they’ve heard the fruit is too high in sugar,” says Homan. As bananas ripen, much of the resistant starch changes to sugar. But the health benefits of antioxidants and fiber outweigh the naturally occurring sugar. For those worried about blood sugar levels, pair bananas with a protein source such as peanut butter or a cheese stick for better control.
A small word of warning about unripe bananas: “If you’re not used to eating resistant starch, start slowly to let your body get used to it. Some people can experience constipation, gas and bloating at first,” adds Homan.
Another plus of this fruit? In addition to all the health benefits of bananas, they’re less expensive than many other fruits.



If you suffer from back pain, you’ve probably heard that strengthening your core can bring you some relief. But is this always true? And if so, how do you do it? We spoke with Cleveland Clinic physical therapist Patti Mariano, DPT, to find out.
When most people think about the core of the body they think of the abdominal or six-pack area just below the ribs. While the abdominal muscles are an important part of the core, we consider other areas important, too.
Your core includes:
Your core also includes the diaphragm and muscles of the pelvic floor. I also consider the gluteal muscles as core muscles.
Theoretically, if your muscles around the low back are weak, your body will rely more on passive structures, including ligaments — the tissue that connects bone to bone — as well as the spinal bones or discs, which lie between the spinal bones, for stability, which can cause pain.
But some studies have shown that specific core exercises are not any more beneficial than general exercise for low back pain. What we know is that exercise in general can help, and focusing on core muscles may provide some additional benefit.
Here are my top five:
For the plank exercises, start by holding them for 15 seconds to 30 seconds. For bird dog and scissors, try three sets of eight or 10 repetitions. For upward dog, do one set of 10 repetitions.
Any exercise performed incorrectly, whether it is core-strengthening or otherwise, has the potential to cause discomfort.
Twisting exercises or even incorrectly completing the exercises cited above can cause pain in the low back. But it’s highly unlikely that one repetition of an exercise will seriously harm your body, unless it’s an exercise using a very heavy weight.
The best way to keep your body safe is to listen to body cues such as pain during and immediately after an exercise, and the next day after exercising.
If any of the following is going on you should consult with your doctor:
Physical therapists train as musculoskeletal experts — they are the experts on muscles, bones and human movement. These professionals are the most qualified, aside from an orthopedic doctor, to assess back problems.
Since there are many factors that impact low back pain and many types of low back pain, it is a good idea to visit at least one time with a physical therapist for an evaluation and subsequent plan of care. This will give you an individually tailored plan with exercises that progress safely.
The idea of core strengthening, while beneficial, is just one piece of the low back pain puzzle.
