Yes — Fast action bread yeast by Hovis is ultra-processed, so it counts as a UPF (ultra-processed food). The product contains industrial additives including an emulsifier (sorbitan monostearate) and a stabiliser (calcium sulphate). These extracted and synthesized additives classify the yeast as an ultra-processed food under NOVA, even though the main ingredient is dried yeast.
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.
