Really? Nebraska isn't in Canada?

This exhange caught my eye for some reason
"Surgipedian #2, feeling outdone: "I think it's something about having not
enough oxygen in your blood!"
Surgipedian #1: "Can you cite a source for that?"
Surgipedian #2: "My aunt Thelma had something like that and I wrote a paper
about it for my biology class at school!"

Sorry, where I was raised anyone using "my relation/friend/neighbour is an
expert so I know about this" would be subject to severe ridicule. It's much
easier than providing evidence and difficult for others to verify the
veracity.
I never claimed to. I only entered this thread when you posted
"Valuable nutrients? In sugarcane juice? Can you name some?"
Which seemed to imply there weren't any nutrients.
There are some nutrients in anything, if only from the fingerprints on
the surface.
This discussion, like all good discussions, circles back to
electronics. Looking at the physics, the classical electromagnetics
and the quantum mechanics, every signal, every voltage, and every
magnetic field couples into every circuit in your box, or in the whole
universe. The "engineering problem" then becomes to catagorize every
coupling into one of three catagories: too small to matter, big
trouble, and needs more analysis. Since the number of couplings in
even a small circuit is astronomical, it's crucial to quickly assign
as many as possible to the "too small to matter" category, which
sometimes takes active design decisions to make happen, like using a
ground plane on a circuit board.
Experience, if you have it, is usually enough to dismiss most
problems; a ribbon cable that drives relay coils won't have enough
crosstalk to glitch the loads. When experience fails, a rough mental
or back-of-the envelope calculation is often enough to show that some
hazard is orders of magnitude safe, so can be ignored. That leaves a
few cases that need serious, quantitative math or, lacking the tools,
equivalent experimenting.
As an engineer, I figure that getting 0.1% of my required potassium
intake from brown sugar is effectively zero. So I'll buy the sugar
that tastes best. The argument that vital nutrients have been refined
out of (or into) the sugar is qualitatively true but *quantitative*
nonsense. If you want potassium, eat a banana.
