I fully backup nearly all of what you said !

For those having trust issue and/or lack of insight,
I studied medicine, then Chinese medicine.

I have to add that for food, each body is different so generalization is impossible.
The only thing is most of food is poisoned (a way or another)
So keep it simple with quality unprocessed food.

The part I did not backup is the white salt.
Most of the time additives are put to make salt look white (because it sell better)
With the traditional harvest most of your salt is grayish and a few quantity is white (the better but much more expensive)

It is shown on this video

And keep in mind that with the global planet poisoning it will become harder and harder to eat unspoiled food.

Happy though though : Your body is a very well made and can adapt to many stress :)
