No — Pure Butter Shortbread by Walkers is not ultra-processed, so it is not a UPF (ultra-processed food). The product only contains basic culinary ingredients (wheat flour with minerals and vitamins, butter, sugar, and salt). These are minimally processed foods or simple fortification ingredients, with no industrial additives like emulsifiers, artificial sweeteners, flavor enhancers, or industrial sugar syrups. Therefore it is not classified as ultra-processed under NOVA.
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.
