JD Wetherspoon is due to switch to a healthier cooking oil that contains virtually no trans fats in all its outlets by the end of this week. The pub operator will cook with a new type of oil from 30 March, which keeps the saturated fats level below the amount recommended by the World Health Organisation. Jameson Robonson, food development manager, said: “This is an important step by the company and highlights its commitment to preparing and serving healthy food to its customers.” The announcement comes after Orchid Group, the pub and restaurant operator, pledged to ban trans fats from its estate and change to a non-hydrogenated rapeseed-based oil earlier this year.
