According to Healthline, the high fiber content in bananas helps create a lasting feeling of fullness, reducing the urge to snack. Research on pre-diabetic individuals found that eating up to two bananas per day, when paired with a balanced diet, does not cause a significant spike in blood sugar.
Bananas also support weight management by reducing overall calorie intake.
However, people with kidney failure or those who need to limit potassium intake should exercise caution. Eating too many bananas on an empty stomach may cause discomfort, especially for those with ulcers or high stomach acid.
The recommended amount is 1–2 ripe bananas per day for optimal nutrient absorption and health benefits.
