I have a theory about why people are getting fat.
you know, the minerals in the soil were deposited for the most part from the grinding of stones under glaciers from the last ice age right?
After years and years and years of repeated plantings on the same ground, those trace minerals are depleted. Modern agriculture does not replace them. Just the commercial fertilizer is added, for the most part.
So, when the body needs these minerals, and can't find them in the foods like now, the body keeps demanding that we eat, and eat, searching for the things it needs.
The more we grow on ground that is depleted, the less nutrition is in the foods.
You can add back some of these minerals with rock dust or stone flour that you can sometimes get from a stone mason, like where they make tombstones and things.
also, I think biochar is very helpful for the soil.
If you want to feed the body, you have to start with the soil. It's by far, the most important thing.
