Green bananas contain more fiber than riper fruits because the pulp has not yet been broken down into simple sugars. Before a banana has ripened, its fiber is a resistant starch that remains in the colon and is not dissolved by the small intestines. This gives a person the feeling of fullness, decreases the appetite and could help with weight loss efforts.
A banana contains about 14 grams of sugar and 1.3 grams of protein. One banana also provides 25 percent of the daily recommended value for vitamin B6.Learn more about Nutritional Content
