I saw upp in the daily mail and just finished reading the most interesting book. I have always been a gardener and grow lots of fruit and vegetables. I have been avoiding additives and sweeteners for a long time. I have always noticed the better taste in my food I grow, especially tomatoes.Mine is the only vegetable garden in this area. I'm a child of the fifties and then ,all the gardens here were vegetables. We need to renew that wartime strategy and all grow something. It's tastier and healthy. Thanks to Chris, I did manage to finish the book and learnt a lot about upf. We need him to advise our government. Jim Crellin
