A single large banana (136 grams) contains 1.5 grams of protein. This amounts to approximately 3 percent of the average daily value. It's important to remember that daily values may be higher or lower depending on individual nutritional needs.
While they are sometimes criticized by nutritionists for being high in sugar and calories, bananas contain healthy soluble fibers and a large dose of potassium, which helps to balance the body's fluids. They are considered a good addition to the diet of any age group, from babies to adults, and are often used to improve the health of malnourished children and boost the performance of professional athletes.
