I don't think we are being duped. I do think some regular fruit and veggies are better than others though. And the trouble is as well that fruit and veggies don't come with ingredients added, but some should! Considering the chemicals that are added to them. I can say that I personally have very little access to organic foods financially. I usually spend more to buy organic corn because that's available at the supermarket and snow peas sometimes too, but the rest isn't. And looked at from a traditional point of view my diet over the past few months has been crap, all over the place, missing meals days without food, sometimes not long enough even to get into ketosis, so no doubt I should have been susceptable to some kind of malnutrition if my actual intake while I was eating wasn't sufficient. In earlier attempts at fasting when I was younger I became quite pale after doing shorter fasts and breaking them not so well as I do now. I've been watching for that paleness, a sure sign of aneamia, and there has been none. I have no doubt that the raw food I've been eating has enough nutrients for me to live on. After all it's a huge variety we have, much more than would be available in nature.
If I had the money I wouldn't hesitate to buy organic almost exclusively. Alas I do not though so I live on what I can afford.
