Obviously you aren’t. There is presumably something in your physiology that is interfering with the way they test for blood potassium levels. If you literally had no potassium you would be dead instantly. And I mean instantly.
I’ll say this. I was living alone at the time (and did so for a while after that) and when I read that, I went and purchased several bottles of orange juice (and started eating fruits as well).
My niece’s young toddler son was living with his young father and the father’s girlfriend for many months, until they unceremoniously dumped him on his grandmother’s door and simply said they could no longer care for him.
He was skinny and had sores on his skin and mouth ulcers, apparently they could not afford formula so fed him mostly cow’s milk(he should have been weaned mostly by that point) or were just neglecting him who knows. A doctor pronounced him to be vitamin deficient.
I assume there are many similar cases due to neglect or poverty.
Western medicine (not to sound like a new ager) has been far too slow in recognizing the importance of subclinical deficiencies. Even the claim that a balanced diet is sufficient arrogantly presumes that we understand all of the biochemistry involved in normal, healthy metabolism when clearly we do not.
My claim doesn’t make that assumption, because to me a balanced diet is *defined *as one that provides everything necessary without an excess of anything.
We certainly are a long way form knowing what a balanced diet actually is, though we have some very good ideas about what it isn’t.
