I tried to learn a little more about pyruvate, but no idea
showed up, how this idea shoul work.
Pyruvate is not only derived from carbs, but also an intermediate stage
in gluconeogenesis from 3 certain amino acids.

I may be (probable for me) that the pyruvate scheme just provides
a picture (or pattern or idea) to keep in mind, which may work
because it involves some other (not understood) mechanisms.

Like Hayes seperation may not work with because of the digestion acids
but because of other mechanisms. Like less mixing of species.
But works.

Banana, rice, potatoe?
Fine rich carb sources (all are producing pyruvate).
What comes to my mind, reading this:

These 3 (can) have sufficient thiamin - at least compared to all sweets.

In this way, Pennington's  "excess pyruvate" would be right again.
Because a lack of processing enzymes in a later stage of the
Citric acid cycle stops is at an earlier stage.
Pyruvate is a very early stage of the CAC and pyruvate could pile up
if the next processing enzymes are missing.
