Bananas and plantains are similar, but they have a few key differences in flavor and usage. bananas are usually smaller than plantains, with thinner skin and softer, sweeter flesh. Plantains are bigger, with thicker skin and starchier fruit. Plantains are primarily eaten cooked, while bananas can be eaten raw or cooked. both fruits ripen from green to yellow to brown, and they are edible at every stage. However, green bananas can be bitter.
Plantains have a higher starch content than bananas, so they aren't quite as sweet, especially if eaten when still green. the less soft, slightly tough plantain fruit is best eaten cooked: sauteed, fried, baked, or even boiled! In many cuisines, plantains are about as likely to feature in savory dishes as in desserts. Plantains are commonly enjoyed in Caribbean, African, and South American cuisines.
In terms of nutrition, both bananas and plantains are good sources of several vitamins, including potassium, magnesium, and vitamin C. They're also good sources of fiber.
