Wyndahoi saidKeep in mind that blueberries have much higher pesticide residues than cabbage does. Buying all organic is expensive, but it's probably a good idea to avoid the foods that are higher in pesticides.
I may have missed something, but blueberries weren't mentioned in that link, were they? My husband grows all his own cooking herbs, about as organic as you can get. No pesticides, although they can be subject to iquana predation. For which we use an iquana repellent, totally natural, from garlic, cinammon oil, and other natural and non-toxic ingredients. Doesn't always work, though.
And aside from pesticides, I've read that vegetables grown on a large scale tend to have fewer beneficial nutrients than those grown in your own garden. Some of it has to do with selective breeding, that favors plants that grow faster & larger. Not to mention GMOs.
So I really don't know anymore. You try to do the right thing, but that's a moving target that changes almost from day to day.
