About Chestnut
Chestnuts are the edible nuts of trees from the Castanea genus, commonly grown in regions such as Europe, Asia, and North America. Known for their mildly sweet flavor and starchy texture, chestnuts are often used in roasted forms, purees, or as additions to soups and desserts. They are nutritionally distinct from other nuts due to their lower fat and higher carbohydrate content. A 100-gram serving provides approximately 206 calories, 2 grams of protein, 45 grams of carbohydrates, 2 grams of fat, and 3 grams of fiber. Chestnuts are also a good source of vitamin C, providing approximately 24 mg per serving, along with smaller amounts of calcium (18 mg) and iron (0.9 mg). Their profile makes them a popular food in festive cuisines and a nutritious addition to diets across various cultures.
