The key nutrient in bananas is carbs, but the carb arrangement or quantity changes extremely during ripening.

Unripe bananas have high quantities of starch, and some of that starch is also resistant starch (c).


Since the starch in a banana is transformed to sugar throughout ripening, yellow bananas have much less resistant starch as compared to green ones. Due to which, the resistant starch composition of a fully ripe banana is less than 1% (c).

Resistant starch is a kind of dense carbohydrate that outflows digestion and functions similar fiber in the body.

It spreads the colon undigested, where it feeds pleasant gut bacteria (3Trusted Source, 4Trusted Source).

After the bacteria digest resistant starches, they produce gases and short-chain fatty acids (SCFA), which are vital for digestive health (5Trusted Source, 6Trusted Source).

About 95% of these SCFA is then quickly absorbed by the cells in the colon and consumed by the body for energy (5Trusted Source, 7Trusted Source, 8Trusted Source, 9Trusted Source, 10Trusted Source).

So though resistant starches will not yield as numerous calories as regular carbs throughout digestion, they may be changed into SCFA’s that provide calories later.

Therefore, green and yellow bananas might provide alike amounts of calories in the end.


Unripe bananas have high amounts of resistant starch. Resistant starch outflows digestion and feeds the welcoming bacteria in the gut, which consume it to create short-chain fatty acids.
