Irradiation doesn't kill just the pathogens, but also lots of nutrients, the same way microwaving destroys nutrients (if there are any nutrients left in microwave-able food-like substances).
Almond growers won to get their irradiated(aka, cooked) almonds labelled as "raw". They couldn't keep their almonds from getting contaminated with pathogens (do they pick up these pathogens on the trees and in the nuts, or later?), so they kill the pathogens and much of the good stuff in
"raw" almonds.
You can't get healthy taking supplements. They are meant to "supplement", not replace.
In the health care war, prevention for cost savings gets very little traction, although 100s of $Bs are wasted every year (vs. just $100B/year reform is supposed to cost) treating life-style, preventable, self-inflicted, corporate-inflicted diseases.
But, we must above all remain "free" to make ourselves irresponsibly sick, and let everybody else pick up the bill.
