Vegetarian Means Lousy Hunter
Frequently dismissed as cranks, their fussy eating habits tend to make them unpopular with dinner party hosts and guests alike.
… research showing vegetarians are more intelligent than their meat-eating friends.
A study of thousands of men and women revealed that those who stick to a vegetarian diet have IQs that are around five points higher than those who regularly eat meat.
…researchers say it isn't clear why veggies are brainier - but admit the fruit and veg-rich vegetarian diet could somehow boost brain power.
There actually may be something of value to the study, but like all scientific studies it is nothing more than the current understanding of a phenomenon based upon the accuracy and design of the study.
Of course, the next question is what is the significance of the IQ test, and does it actually measure anything of value to the human race? The human brain is phenomenal for humans, but it would be pretty stupid in the world of a snake or crocodile, which are 100% carnivores. I doubt a vegetarian snake or crocodile could be judged more intelligent than their carnivore brethren since the vegan reptiles would soon starve to death.
Humans evolved as omnivores so I doubt that totally giving up meat is likely to be the smartest move, despite the IQ advantages. You can’t eat an IQ level and a filet mignon still tastes mighty good. Medium rare please.
