Yes — Cook's Belgian Dark Chocolate is ultra-processed.
This product is ultra-processed because it contains soya lecithin, an emulsifier and a pre-identified UPF ingredient. Sugar, cocoa mass, and cocoa butter are basic chocolate ingredients, but the added emulsifier leads to the UPF classification.
Other crisps, snacks & nuts Nomi has checked — these ones aren't ultra-processed.

Ultra-processed foods (UPFs) are industrial formulations made with ingredients and additives you wouldn't find in a home kitchen — such as emulsifiers, artificial flavourings, colourings and modified starches. The classification is based on the NOVA system used by researchers and dietitians worldwide.
