Kenneth George Haig MRCS LRCP (20 February 1879 – 1958) was an English physician and writer, best known for promoting the uric-acid free diet.
On this diet all meat, fish, fowl, egg yolks, beans, lentils, peas, oatmeal, mushrooms, wheat meal, cocoa, coffee and tea are forbidden.
[5] Haig wrote that beans, lentils and peas contain large quantities of purines and are poisonous because they produce uric acid.
A reviewer in the Journal of the American Medical Association disputed this as "common people have been consuming such substances for ages without showing any ill effects.
"[7] In contrast, it was positively reviewed in the Nature journal for "approach[ing] the subject with such wholehearted enthusiasm that he equals, if not excels, that of his father, whose work he continues and extends.
