Re: The evolutionary role of cooking

I learned from the article that cooking "denatures proteins." I happen to be very allergic to all raw produce except grapes, apples, onions, lettuce, and spinach. Everything else needs to be cooked. No crudités or fresh orange juice for me. People look at me funny and ask why cooking would make a difference. I say, "I dunno, but it must break down my allergy molecules so that I don't react to them." Then they (idiots…

So you're allergic to folded proteins? That seems unlikely since even those few raw things you can eat have trace amounts of different proteins in them. If I were very allergic to so many different foods, I'd want a real explanation for my own sake at least, and not just try to snow people with scientific jargon.

I would love a real explanation. But believe you me, allergy science is just getting started. (So is a heck of a lot of other medical knowledge.) "Allergists" didn't even exist until a few decades ago. "Allergy and immunology" is a pretty new specialty.

My pediatrician switched his practice to "allergy and asthma" in 1970. He told my mom he did so because he wanted to try to help whatever the heck is wrong with me. Well, I can't read his mind for motives, but that's what my mom reported.

I astound and baffle allergists when their tests reveal the huge numbers of foods--and varieties of foods--I'm allergic to. (Note to self: I am not going into my other allergy foods here.) Their first reaction is to blurt out, "What do you eat?! How do you live?! It's a wonder you're alive!" After that, their reactions and attempts to help vary considerably. The closest I've gotten to an explanation from a live doctor is hearing one mutter something about "volatile oils" into his Dragon Naturally Speaking before walking off and leaving his nurse distressed for my sake.

I do get strange satisfaction knowing that food allergies have gotten much more prevalent in the past decade or so. This means more researchers take more interest in it, the FDA changes its food labeling laws, the general populace has a little more knowledge, etc. When I'm feeling grandiose, I tell myself that my strange body (and that of a guy I spoke to on the phone who is a guinea pig at the Mayo because he's allergic to all foods) are the vanguard or cassandras or whatever for something new and weird going on in the world. But perhaps I read too many Greg Bear novels. ;-)

I subscribe to an allergy research newsletter from South Africa, which contains a lot of fascinating, nerdly stuff I never hear from live doctors. And when I do try to mention research, I get, "That means you don't need me except to prescribe Epipens." But I got away from reading it a few years ago. I think I'll head back to doing so. Thank you for indirectly putting the bee in my bonnet. http://www.allallergy.net/abstracts/index.cfm

Ah! A quick glance reveals an article called "The importance of nasal provocation test in the diagnosis of natural rubber latex allergy." This just might pertain to me even though I have a banana allergy, not a latex allergy... But I think I'll leave it for a few days. This whole topic is getting way too heavy today. Bye, folks. I'm logging out.

Someone I know is highly allergic to pineapple; eating more than a few bites could easily cause her to suffocate to death without intervention. She didn't realize this for years because she only ate canned pineapple, which doesn't affect her at all. One day she had dried (but not cooked) pineapple and went to bed; fortunately she didn't like the taste and only had a bite or two because she woke up swollen and having a hard time breathing. After that, she was still able to eat canned pineapple without any problems. Whatever it is that causes the reaction must be broken down for good by heating the pineapple to canning temperatures.
