I exchanged a few emails with you early last year in regards to a breathing problem I've had since my early teens (I'm 41 now) and thanks to your information on how to watch out for certain foods my life is MUCH improved. I have been weight training since my late teens and have picked up quite a bit of knowledge on nutrition along the way but looking deeper into foods containing preservatives, sulphites etc has opened my eyes to a whole different side of eating. As an ex-smoker I always put my problem down to that but limiting my intake of mince meat, prawns, pizza, processed meats etc. to a very small percentage of my diet has done more for me than giving away the cigarettes. – Richie, Vic
