This is a brilliant video. Germany and Russia have been using this intervention (in my view the most effective / speed to reverse many conditions) for decades. It would be great if the manual archives they have were "electrified", this would be a goldmine of relational information.
Due to the 2nd world war, the German research was ignored leaving the door open to persons such as Ancel Keys to come up with hypothesis'.
It is interesting as an aside that Germany has differing RDI's to the Americans.
