I had an allergy test early this year, when I had a routine medical MOT, and I don't have any allergies. Not to wine, bread, chocolate, or anything. This cannot be a coincidence - it has to be to do with my diet. I always have five or six portions of fruit and veg a day, meat only twice a week, and litres of water. I have to confess that I do start the day with hot water and lemon, but I always end it with a convivial bottle of wine.
