"he thinks that cooking and other forms of preparing food are humanity’s “killer app" Am I the only one that thought killer app was only used in reference to web/technology platforms :)

Yeah, it's also used by journalists and bloggers who want to sound more clever than they really are when talking about subjects in which they have no formal training or practical experience.

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…

Yes, that's right. Most plants have a number of defense mechanisms to ward off insects, bacteria, fungus, etc. to avoid being devoured. (Plus other physical barriers, but that's not the problem here.) If a certain animal can eat a certain plant, it's usually because the animal has its own mechanisms for handling the defensive proteins, or hosts bacteria that can do it. You're probably missing some of these.

Heat makes a protein unfold; and unfolded protein still has the amino acids you can metabolize, but no structure, so it can't do anything.

And guess what? Cooking produce probably does help him because it denatures the proteins present in the food. Your post is nothing besides internet tough guy posturing, which I do find entertaining, if a bit annoying.

The more you know!

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.

Some lactose-intolerant people do better with cooked dairy products, like pizza. Biology isn't like computers; usually a small bug, like a protein the body can't process, is fine in trace amounts. Even a little strychnine is fine in trace amounts.

I apologize for implying that you are an idiot. I was being facetious after taking the news of "denatured proteins" in a happy, light-hearted manner.

As for the allergies, shall I come to your home for a demonstration? You can watch my lips and tongue swell up while I scratch my chin and neck something fierce and spend a couple hours wheezing. It's pretty frightening to watch, and it gets worse over the years. I'm glad I've needed to be hauled to an emergency room only once. I do keep an Epipens on me.

Someday when you are prescribed Epipens by bona fide allergist MDs, you will be handed several brochures. Some of them will comfort you with the statement that many people out there, commonly your most immediate family members, won't believe you and think you're (consciously or subconsciously) making this all up. And some of them are designed for other people to read so that they will take you seriously.

To be honest, living with dangerous allergies--especially a large number of bizarre, dangerous allergies--is mind-blowingly tough, physically, nutritionally, logistically, emotionally, socially, and professionally.

Enough with the heavy stuff. I shall end on what I hope is a more pleasant note. I find it amusing that when I make an occasional trip to a health food store and people ask me about my grocery needs, about 3/4 of them recommend some naturopath or other for some loony muscle test, and the rest are firmly convinced there's no such thing as allergy at all to anything "natural."

We live in a strange world. :-)

You're right, I've never heard of that, and I still think it's bullshit.

If you're allergic to fruit, vegetables, and nuts, you might just consider killing yourself to make the gene pool a little cleaner.

Unbelievable.

Hooray! Thanks for spotting "denaturation" in the Wikipedia article (an authoritative source, I know). I hadn't bothered to look for anything about allergies there in years.

Yes, my three allergists have all called it "oral allergy syndrome." One of them speculated my problem might have to do with "volatile oils," considering I'm also allergic to the smell of the raw produce. 19th and 20th century chemistry is amazing. Did you know that "flavors" for factory foods are food perfumes, top secret stuff concocted by perfume chemists? I learned that around ten years ago in a book called Mauve, about the history of fabric dying, of all things. (Some years earlier, I concluded the scent that remains long after slapping on some Polo is blueberry from old Betty Crocker blueberry muffin mix.)

So the thought of being allergic to volatile oils made pretty good sense to me. But as soon as I say "volatile oils" to people in combination with "cooking," they get all confused. Maybe they think I want to solve my problems by blowing up my kitchen or setting the building on fire or starting a heated argument. I'm happy to think that "denatured proteins" will sound a lot less volatile.

BTW, I'm a she, not a he. I also happen to be blondish and thin with a weak voice. I find that many people in real life, whom I shall not bother to classify here by occupation or sex, don't take me seriously. If you like, you can picture Julianne Moore in "Safe," a film which I find both uncomfortable and terribly funny.

I'll take it into consideration.
