Dietitians Back 1 Daily Banana, Citing 422 mg Potassium and Limited Drawbacks

Summary
One banana a day is generally healthy, dietitians said, with a large banana counting as 1 cup of fruit toward the USDA’s roughly 2-cup daily recommendation for adults.
A medium banana delivers 105 calories, 3 grams of fiber, 422 mg of potassium and 0.5 mg of vitamin B6, nutrients experts say support digestion, energy, fullness, blood pressure and mood.
Underripe bananas may further help gut health through resistant starch, while pairing bananas with protein or other fiber-rich foods can blunt blood sugar spikes and improve satiety.
The main cautions center on overdoing intake: 27 grams of carbohydrates may raise blood sugar, ripe bananas can trigger headaches in some people, and excess potassium may be risky for people with kidney issues.
Dietitians still recommend bananas as part of a varied plant-based diet, noting only 1 in 10 Americans eat enough fruits and vegetables each day.
