Chestnuts are small, and have a round, oval, to slightly ovate shape with one flat side. The nuts taper to a point at one end and have a thin, dark mahogany skin showcasing a glossy sheen. The surface also features textured striations extending the length of the nut with a light brown, semi-rough cap. Beneath the skin, the flesh ranges in color from beige to white and has a meaty, chewy, and starchy consistency. Chestnuts are nutritionally dense with relatively low-fat content. The nuts contain high amounts of dietary fiber and are a decent source of protein, a significant source of selenium, and contain vitamin C, vitamin b6, manganese, potassium, and copper.
