Chestnuts are the only low-fat nuts, with a fraction of the calories of other types of nuts. They contain just 1 gram of fat and a little less than 70 calories per 30 grams of dried or roasted nuts.
The downside is they're lower in vitamins and minerals. But they're still relatively nutritious and provide some carbohydrate.
They radically increase their caloric intake once they're boiled.
Of all the different types of nuts, chestnuts are the only nuts that contain vitamin C. Just 100 grams of chestnuts supply 45% of the RDA of this vital antioxidant nutrient.
