The chestnut season returns every autumn, bringing with it cooler evenings and the comforting smell of the nut that fills the air in markets and streets. Chestnuts are often enjoyed roasted and warm, offering a unique taste that many find appealing. They are also packed with nutrients, including fiber, complex carbohydrates, and various micronutrients, which make them interesting for those paying attention to their health. According to the restaurant City Wok, chestnuts are typically available on menus from October through December, making them a seasonal treat. The Spanish Foundation of Nutrition (FEN) reports that 100 grams of chestnuts contain about 209 calories, which is much less than the 500 calories or more found in the same quantity of other popular nuts like walnuts, pistachios, or almonds. Nutritionists often describe chestnuts as a unique type of fruit that grows in a shell, rich in complex carbohydrates and low in fats. This makes them almost like a small, edible starch wrapped in a shiny, protective shell. Claudia Miñana, a nutritionist, explains that chestnuts can serve as a sustainable energy source and help with feelings of fullness, digestion, and blood sugar control, especially for people at risk of developing type 2 diabetes. She notes that chestnuts are low in fat and high in complex carbohydrates, which provide a steady release of energy. In addition to their carbohydrate content, chestnuts are also a good source of dietary fiber, along with essential minerals such as potassium and iron, and they contain vitamin C. These nutrients contribute to overall health and support various bodily functions. Miñana emphasizes that chestnuts are not only filling but also offer a range of benefits that can support a balanced diet. As the season comes around each year, chestnuts continue to be a popular and nutritious choice for those looking to enjoy the flavors of autumn while maintaining a healthy lifestyle.
