Any diet to one extreme, Carnivore or Vegan, is not healthy in the long run. After my kidney transplant, they told me the diet I should stick to is a balanced, sensible one. My monthly blood tests, which I am going for today, show my electrolytes, etc. all in the normal range along with my vitals. The only dietary restriction I have are NO grapefruit or pomegranate EVER again as those interfere with the activation of the anti-rejection meds in the liver.
