Dr. Jackson explored the grains over 100 years ago.....
I know today that many farmed "Grains" are plagued with eggs--from moths and all sorts of bugs. Every grain can have a worm that hatches and eats the grain---oats especially.
Almost always it is not the grain and the outside of the grain that they say has the benefits.
Keeping in mind--every grain has zero root bark, therefor all minerals are going to be "inorganic" in "SIZE"-- too large!
Yet, the Jackson Method turned his old near dead body into a superman.
