Michelle Berriedale-Johnson is an expert on food allergies and intolerances. She has spent all her career in the food business, first as a caterer then as a journalist and food writer. She became interested in special diets over 20 years ago when her son was diagnosed as being dairy intolerant. She set up a food company, Berrydales, specialising in additive free, dairy free, gluten free and egg free foods and a quarterly magazine, The Inside Story, about dietary problems. In 2000 The Inside Story, was re-named Foods Matter, and became a subscription magazine supporting anyone with a food allergy, food intolerance or living on a free-from diet. Foods Matter has now become an online magazine and portal www.foodsmatter.com. Michelle is also the author of Cooking Gluten, Wheat and Dairy Free and Diabetic Cooking for One and Two (also published by Grub Street).
