So now we learn that the Paleo Diet may not be all it is cracked up to be. Or so says Yet Another Diet Study.
Kenneth Roberts decided to study the popular diets back in his day (pre 1945 for "An Inquiry into Diets", which the linked post cites):
…every diet, in the opinion of one or more diet experts, is either based on the erroneous ideas of a faddist, or is downright dangerous.
Hitherto, in consulting references on any given subject, I have usually been able to discard the majority as inaccurate, biased, unreliable, or untruthful … Diet books are different. Most of them are written by medical experts who have studied for years to find out exactly what happens to seven cents’ worth of liver when it meets a Welch’s bacillus in the upper colon of a sedentary worker aged forty-five.
Whatever the popular diet, wait a few years and new YADS will disparage it.
