As a parent of a young woman with a severe peanut allergy, allow me to (hopefully ) make a few things a little clearer. It is true that nut allergies and peanut allergies in particular are on the increase. Atopy or the state of being sensitive to certain everyday items is now commoner than it ever was, almost cerainly down to uses of chemicals and changes in our environment. It has also been postulated that our obsession with hygiene may fail to expose babies and children to compounds at an earlier agewhen their immune systems are evolving (Gammaglobulins) - so called "clean dirt". Asthma was something that afflicted fat wheezy boys when I was at school 30 years ago. Now something like one in 5 kids have "asthma" and carry inhalers and they are by no means fat. Nut allergies have risen exponentially over the years and it was, until a few tragic cases made the headlines, extremely difficult for parents whose children were allergy free to understand the severity of these reactions. Nut allergy sufferers do not chose to have this affliction- nuts in one shape or form occur in a bewildering number of every day products and are not always obvious in their presence. Surely it is common sense for these materials to be excluded from the aircraft cabin for the duration of the flight as it would be for any other noxious material which had the potential to cause illness among passengers? Earlier posts mention Adrenaline Auto injectors. These vital pieces of equipment BUY TIME - the user should still go straight to an emergency dept as further medication in the form of more powerful steroids and further adrenaline is frequently needed. Anaphyllaxis in an enclosed aircraft cabin at FL370 over the Atlantic does not bear thinking about - especially if it`s your family member.
