My mother carries “healthy” ideas to extremes. She once cut her salt back to the point that her electrolytes were so screwed up she ended up in the ER on an IV. This kind of stuff did not stop her from criticizing her father in law for eating bacon and eggs every morning. He was 93 and still riding a motorcycle.
I too had to go to emergency room for electrolytes imbalance, Spent 5 days on IV to get the sodium level back.
