Are chestnuts low-carb?

No — chestnuts are the carb-rich exception in the nut family. That is exactly why they energize and warm in winter. If you are following a strict low-carb protocol, they belong with grains, not with almonds or walnuts.

Can I eat chestnuts raw?

No. Raw chestnuts carry tannins and are difficult to digest — always roast or boil. Scoring the shell in a cross before roasting prevents them from bursting.

Are chestnut flour and chestnuts safe on a gluten-free diet?

Yes. Chestnut is naturally gluten-free and one of the classical winter starches for coeliac and gluten-sensitive kitchens.

Are horse chestnuts the same thing?

No. Sweet chestnut (Castanea sativa) is edible and delicious; horse chestnut (Aesculus hippocastanum) is a different tree entirely and is toxic.
