They are also healthy as they are high in Vitamins B1, B2,B5, B6 & Vitamins C and in Potassium and Magnesium.
For me they are the taste of autumn and Christmas!
Be aware, these are spiky little buggers! Most trees will release the nuts from their thorny shell! One of our trees keeps them in the outer shell. You need tough leather gloves to release them. This is the tree with the biggest chestnuts I have ever seen...off course! You can also put the closed spiky shelled ones in a basket in a warm place for 24h, they will open and it will be a little easer to retrieve the nuts. But you will still need good thick leather gloves.
