Yes — kefir rhubarb fermented yoghurt by Yeo Valley is ultra-processed, so it counts as a UPF (ultra-processed food). The product is classified as ultra-processed because it contains at least one ultra-processed ingredient according to the NOVA system: natural flavouring. All other ingredients are minimally processed or basic culinary ingredients, but the presence of natural flavouring (an industrially produced additive used to modify taste) is sufficient to categorize the whole product as UPF.
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.
