Plantains are a type of starchy fruit that is commonly eaten as a carbohydrate source in many parts of the world. They are a close relative of bananas, but unlike bananas, they are typically cooked before eating. Plantains are a popular ingredient in many cuisines, including Latin American, Caribbean, and West African cuisine.

As a carbohydrate source, plantains provide a significant amount of dietary fiber, vitamins, and minerals. One cup of sliced plantains (about 148 grams) contains approximately 200 calories, 50 grams of carbohydrates, 3 grams of fiber, and 2 grams of protein. While plantains do contain some protein, they are not considered a significant source of protein.

It is important to note that while plantains can be a nutritious part of a balanced diet, they are also relatively high in carbohydrates and calories, so they should be consumed in moderation as part of a balanced diet. Additionally, people with certain health conditions, such as diabetes, may need to be mindful of their intake of carbohydrates and should speak with a healthcare professional for personalized dietary advice.
