Yes, your points are all well made, and I can't disagree. Of course mineral-rich food is going to contribute to good health, as you mentioned with the remote cultures. But I would look at the larger picture where those people's good health is concerned.

I will repeat myself: there is a type of "organic farmer" who does not use anything artificial - and not anything natural, either. They just keep using their soil till it can't grow anything any more. These people either have some land sitting around and decide to mine it for all it's worth for as long as they can - as the Europeans did when they came to America - or they just don't think about mineral content of the food they are growing. We had a neighbour who wanted to be an "organic farmer" and he added no fertilizers whatsoever.

The mineral content of the food they grow is poor because, while they aren't using any chemicals that inhibit mineral absorption, neither are they adding any fresh minerals to the soil which the plants can use. All the while considering themselves "organic farmers".

When I first began "organic gardening" about 25 years ago, I was as ignorant as some of those farmers. I discovered, very quickly, that I had to resort to using pesticides (organically "acceptable" ones) because, I now suspect, the plants were weak from their poor mineral content. Live & learn, huh?
