There are many reasons why plantains are more expensive than bananas. First of all, plantains taste better, are chewier, and have higher nutritional value. They are rich in dietary fiber and water-soluble plant fiber. Regular consumption of plantains has a very good laxative effect. Secondly, the yield of plantain is lower than that of banana, the planting area is smaller, and the scarcity of the product makes it more expensive. Finally, there is a folk saying that rich people eat bananas and poor people eat bananas. The price of bananas is two or three times more expensive than bananas.
