Good morning NJ -
I think there's a big difference between "detectable amount" and a coating of pesticide on produce. Further, many of the pesticides used are KNOWN toxins / carcinogens. Further, many of those compounds can cause substantial environmental and ecological damage.
In our household, we rank produce like this: locally produced and organic, locally produced, organic but not locally produced, and "conventional" and not locally produced. This takes into consideration environmental and ecological impacts as well as health impacts and "how good does it taste!?" We also shy away from big grocery stores and shop much much more at our local food co-operative.
In regards to food, we have realized that buying that beautiful little container of blueberries is about the same cost as buying some processed junk food.... or a cupcake or two... And so, we have drastically reduced the amount of processed food we buy and increased the amount of "expensive" produce items... and our overall food bill really has not changed that much. Yes - it is a little bit higher... but really, not that much.
I think these questions are important to examine. And I'm glad you posted on this.
Also, organic does not mean no pesticides, but it does restrict the pesticides that can be used.
Also, there are many many people that do not want to see organic foods take a strong hold.
So, when I read studies like the one you cite, I often wonder who's sponsored the research etc....
At the end of the day, we should eat mostly plants... and very little processed food. This we know very clearly. So, any step that makes that easier for a person to do should be taken! And... food should be YUMMY! And I've gotta say, that little container of locally and organically produced blueberries .... YUMMY!
Hope everyone has a great day.
