Kidney stones

There is a dietary connection between the development of kidney stones and consumption of animal based protein that was researched over 50 years ago by Dr. W G Robertson.

Chart 10.4 shows one part of his findings, that a small increase of animal protein from around 21 grams per day to 25 grams per day (a mere 4 gram increase) increased incidence of urinary calculi by 50%. He found by simply getting patients to shift from animal protein to all plant protein their kidney stone problems resolved.

Chart 10.5 shows how the excretion of calcium and oxalates in the urine dramatically increase when any excess of animal protein is consumed.

A further factor has also been shown to be involved, free radicals can trigger stone formation in the kidneys, as has been pointed out before free radicals are mopped up by antioxidants found only in to any significant extent in a plant diet.
