Walkers Nonsuch has responded to healthy eating trends by cutting all hydrogenated vegetable oils from its toffees. These now carries no artificial colours, preservatives, or flavourings and no man-made trans-fats in the range.

Ian Walker, MD, admitted large amounts of confectionery were not good for people. "But since they are never going to give up eating sweets, it is best for people to know what is in them and then enjoy them in smaller portions," he said.
