If you could not taste your food, what would you eat? Would you even want to? Taste disorders are rare, but they can have devastating impacts on people's lives. They can also tell us a lot about our food.Emily Thomas meets a cookery writer who says she wanted to die after a car accident robbed her of taste. But as the sense slowly returned she became a more experimental cook.And a man who has not been able to taste anything for five years, explains how it has changed his social life, and how he has found innovative ways to enjoy his food.Plus, we hear calls for more research to develop treatments for these disorders, and how taste could be key in the early diagnosis of dementia.(Photo: A hand holding a black apple.
