A high source in protein, all parts of the winged bean plant are edible, thus earning its nickname of a “one species supermarket”. Despite being more commonly cultivated for its beans, the other parts of the plant are also edible.
Its flowers are often used as a food colouring, and its taste has been famously compared to a mushroom. All parts of the winged bean are said to contain vitamin A, vitamin C, calcium, iron, and are a good source of natural minerals.
The roots of the winged bean can be in fact used as a substitute to the potato; besides its nutty flavor; the roots are also a much richer source in protein than potatoes.
