How Banana Helps In Providing The Right Nutrition

Banana is a simple looking fruit but is a veritable storehouse of nutrition. It grows in warm regions like tropical islands and South East Asia, but is consumed almost all over the world. There are many different varieties of bananas; you can get them in different shades of green and yellow, and some are even reddish in color – and of course, different sizes. The textures also differ, as does the taste.

This is the average nutrient content in a single banana of 100 grams (there may be slight differences according to the variety)

Bananas are an excellent source of carbohydrates; in unripe bananas, they are present as starch, and in ripe ones, as sugars. That is, the composition of the carbs undergoes a transformation when the bananas ripen; fully ripe bananas may contain only 1% of starch, and around 16% sugars. The glycemic index is very low – about 42 to 58, based on how ripe they are. This index shows how soon the carbohydrates n your food enters your bloodstream and elevate blood glucose levels. The GI of bananas is low because they contain plenty of fiber and resistant starch.


Unripe bananas contain huge amounts of resistant starch; this means it doesn’t get digested easily, and passes through your intestine as is. When it reaches the large intestine, bacteria ferment this starch to form a short-chain fatty acid called butyrate, which is beneficial for your intestinal health. They also contain pectin – another fiber; some of this is soluble in water, and it increases when the bananas ripen. Resistant starch and pectin help to regulate the spike in blood sugar levels after eating food.
