UK front of package labelling (FOPL) informs consumers on the nutrient content of food. However, FOPL does not consider food processing, and with the UK government being urged to act on ultra-processed food (UPF), whether UPF should be added to FOPL is unclear. This study compared food and drink in the UK National Diet and Nutrition Survey (NDNS) Intake24 database based on FOPL, nutrient content and NOVA classification, to understand whether UPFs are covered by dietary recommendations for foods high in fat, salt, and sugar (HFSS). NDNS items were coded into minimally processed food (MPF), processed culinary ingredients (PCI), processed food (PF) and UPF according to the NOVA classification, and FOPL traffic lights. UPFs contained greater energy, fat, saturated fat (SF), total sugar (TS), and salt than MPF. UPFs had a greater odds of containing red FOPL and an unhealthier overall FOPL score (odds ratio (OR):4.59 [95%CI:3.79,5.57]; OR:7.0 [95%CI:6.1,8.2] respectively) and lower odds of containing green FOPL (OR:0.05 [95%CI:0.03,0.10]), compared with MPFs. For items with no red FOPL, UPFs still contained greater energy, fat, SF, TS and salt than MPFs. However, several UPFs have healthier FOPL scores. UPFs had an unhealthier nutritional profile and FOPL score than MPFs. For items with no red FOPL, UPFs still had an unhealthier profile than MPFs, with a higher energy density. Importantly, not all UPFs were unhealthy according to FOPL. These results indicate partial overlap between FOPLs, nutrient content and NOVA classification of UK food and drink products, with implications for UK food and drink labelling.
