Nutrient content of key cuts of pork in the UK
Nutrition Bulletin
A new analytical survey on key cuts of pork sold in the UK has been undertaken to determine the current nutrient content of commonly consumed pork cuts and leaner cuts of pork that are becoming more popular. The last government analytical survey on pork for the UK food composition tables was carried out in 1992 and it has been suggested that production methods and feed have changed. Pork fillet medallions, loin medallions, loin steaks and leg joints were purchased from retail outlets to represent pork consumed in the UK and prepared for analysis between January and February 2019. Nutrient values for a wide range of compounds (proximates, inorganics and vitamins) were determined by accredited laboratories. A selection of the results, highlighting some of the main changes are presented. The most noticeable changes since 1992 can be seen in fat where levels have fallen in the lean component of fillet and loin medallions and loin steak. This has impacted the amount of fat found within a cut containing both lean and fat portions. Other changes in both the lean only portion and cuts as purchased are lower amounts of iodine and vitamin B12 and higher amounts of vitamin E and niacin. Even after these changes, 100g of cooked pork still provides a good proportion of an adult’s daily thiamin, niacin, selenium and vitamin B12 requirements with the lean portion being lower in fat. These results provide an insight into the changes made in pig production, including new breeds and changes in pig diet and supplementation. The results will be included in the next update of the UK Composition of Foods Integrated Dataset and incorporated into Public Health England’s nutrient databank which supports the National Diet and Nutrition Survey.
