Food is one of life's necessities and also one of its great joys.
Unless, as often happens with people undergoing chemotherapy, you have no sense of taste.
After caring for his mother through her cancer, food writer Ryan Riley decided to set up Life Kitchen, a free UK-wide cookery class initiative to help people living with cancer focused on taste and flavour.
He speaks to Bryan Crump about the project, the classes, the support he's received and some of his ideas to make food a joy again.
