Chestnuts have the lowest fat and calories, chestnuts are rich in starchy carbs and fibre, and in their raw form are a good source of vitamin C. They’re lower in protein than other nuts but make a useful contribution of B vitamins including B6. Ground chestnut flour can be used as a gluten-free flour for cakes and bakes, or buy fresh and roast for a tasty snack.
