The Banana stem is really not a stem at all; it is the flower stalk of the banana plant. The thick stalks grow up from the ground and form the backbone of the herbaceous plant. Banana stem has a crisp texture and a mild flavor, both somewhat sweet and tart with a slightly bitter after taste.
Banana stem is a rich source of fibre and helps in weight loss. Its high fibre content creates a feeling of satiation and hence, reduces the intake of food. It also helps ease constipation. Banana stem is rich in potassium and vitamin B6 just like the fruit.
