This is begining to sound like the C&R threads. Eat what you want, stay physicaly fit, and be happy. If anything these foods take the years at the end of your life. The years when your a babling, drooling, diaper wearer.
Eat what you want is all about choice, and i'm all for that. I like to know as much as possible about what I put into my body. My choice! What is so wrong about requiring them to state that a product has been irradiated?
From the way it sounds, there are many that will purchase a product for that very reason (irradiation).

Although, there will be some like myself, that will choose the products that hasn't been treated with the irradiation procedure.

Just as saccarin, aspartane, hydrogenated Oil and many other additives and treatments are labeled, why not irradiation? People can still buy their irradiated, hydrogenated, saccarin flavored foods, if the public is let in on what they are purchasing. No one's going to stop them (especially the FDA) from consuming stuff that is proven to harm us if it gets in the way of the bottom line$$$$. Asbestos was once considered safe, until we realized it was a cause of lung disease. Want be long before we all will have to carry a personal Geiger Counter in case a few particulates find there way to the dinner table and our plate.
It seems some people could care less about how food is processed, because as J7 so eloquently put it, "it will only harm us when we are old and babling, wearing diapers, drooling." Same way that Cigarette smoking already impacts our lives (smokers & Non smokers) is exacted by J7's C&R summation regarding food choice and our health. We can smoke for a few decades (if we are lucky) before the lung cancer, the diaper, the drooling, the babbling, etc., set in.
If this is beginning to look like the C&R thread, then I would assume that to side for the non labeling of products that are irradiated, mean that one is for the personal Bonking of themselves.

To support labeling of irradiated foods would be to personally C&R yourself.

I'm a bonified C&R kind of guy, in fishy situations such as this. BTW, self bonking is legal and supported by the FDA, possibly as a way of solving the over population problems.
