Yes — Plain Instant Mashed Potato is ultra-processed.
Ultra-processed: convenient, but not ideal for everyday eating.
This product is ultra-processed because it contains palm oil, which is a highly processed and refined oil, as well as flavourings (containing milk), an industrial flavouring additive. Antioxidant (rosemary extract) is also a pre-identified UPF ingredient and contributes to the classification. Instant mashed potato is additionally a ready-to-eat processed food formulation. The other ingredients, such as potato, milk ingredients, salt, pepper, and colours, do not alter the classification.

Yes — Plain Instant Mashed Potato by Tesco is ultra-processed, so it counts as a UPF (ultra-processed food). This product is ultra-processed because it contains palm oil, which is a highly processed and refined oil, as well as flavourings (containing milk), an industrial flavouring additive. Antioxidant (rosemary extract) is also a pre-identified UPF ingredient and contributes to the classification. Instant mashed potato is additionally a ready-to-eat processed food formulation. The other ingredients, such as potato, milk ingredients, salt, pepper, and colours, do not alter the classification.
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.
