Yes — WAFER THIN OAK SMOKED HAM is ultra-processed.
Not a great choice for everyday eating.
This is ultra-processed because it contains stabilisers—potassium triphosphate, sodium triphosphate, and tetrapotassium diphosphate—which are industrial additives used to alter texture and retain moisture. It also contains the pre-identified UPF ingredient antioxidant (sodium ascorbate), plus sodium nitrite, an industrial preservative used in cured meats. The ham is therefore classified as UPF despite its high pork content.
