Here's an example:  celery. I'm sure many of you in the room have eaten celery, you've enjoyed it, it's been nice, but there's a nice story about celery.  The ladies who used to pack up celery for sale in the supermarket would take the celery and cut it up in pieces so it would fit nicely into the package.  And in doing so, they used to get the celery juice on their skin, on the skin of their hands.  And many realized that they were getting a surface dermatitis as a result of this.  And some of them even got a skin cancer as a result of this.  And of course they started wearing gloves immediately.  Why did it happen?  It happened because of this compound:  5/8-Methoxypsoralen.  This is something that celery uses to stop bugs from eating it so that the bugs die.  There are many different plants that we use as food that also have this compound in them.  This is a potent carcinogen, a very dangerous carcinogen.  But the amounts in the plant are extremely small.  It might cause a little damage to one or two cells, but your body is able to repair these because we have very good repair mechanisms.  So for us, it really isn't a problem, but if celery was a GMO, you would not be allowed to sell it, we wouldn't be allowed to eat it, it wouldn't be in the supermarkets.  And this is where it gets to be ridiculous.  This is why the product is important.  It doesn't matter that maybe it's got some of these compounds in it if it's still safe to eat, then it's safe to grow and safe to sell.
