Slow down the banana from ripening
Bananas are delicious fruits in many ways. Because of their potassium, they are suitable for the heart. They are already naturally sugary, so they contribute to that as well. It is a reality. Another reality is that they ripen very quickly.

You have to wrap a piece of plastic wrap in the black end of the bananas. This section of bananas contains a chemical that makes them ripe, so keeping it isolated prevents the chemical from spreading to the rest of the fruit. How interesting is that?
