Study Links Higher IQ to Vegetarianism

Posted on Dec 14, 2006

A study emerging from Britain claims the IQs of kids who grew up to become vegetarians were an average of five points higher. There was no difference measured between full-blown vegetarians and those who ate chicken or fish (does that even count as vegetarianism?).


The study of 8,179 was reported in the British Medical Journal.

Twenty years after the IQ tests were carried out in 1970, 366 of the participants said they were vegetarian - although more than 100 reported eating either fish or chicken.

Men who were vegetarian has an IQ score of 106, compared to non-vegetarians with 101, while female vegetarians averaged 104, compared to 99 for non-vegetarians.

There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but who reported eating fish or chicken.

Researchers said the findings were partly related to better education and higher occupational social class, but it remained statistically significant after adjusting for these factors.

The study is merely a reiteration of the simple medical fact: The more meat you eat, the stupider you become! I mean, if you consider yourself anything above a total moron or a retard, then you should readily see that meat eating era is OVER!!! Get it? it’s over! Eating dead animals for food is about as outdated and idiotic as wrapping a dead animal fur around your loin for warmth!! Hello, this is 2007, do I need to say more? or has eating all that dead flesh decayed your brain beyond repair!!

Well, according to tests, i have a high IQ. And yes, i´ve been a vegetarian in the past, and i know i will switch to full time vegetarian sometime in the future… This is the first time i hear there´s a correlation.

My depression disappears when i follow a veggie diet. my bad temper, sugar cravings, chocolate cravings… i feel at peace.

When you read all the “miracle” diet books that promise you to be not only thinner, but younger, healthier, smarter, etc. the bottom lines is: Vegetarian diet. Of course they wont say it directly because it will show that they had not discovered “anything new or grounbreaking” really

The thing is, i stopped being a veggie for two reasons:

1)My aggressivity levels fall down to zero.

2)My sexual drive falls down to almost zero

Sadly, I need the aggressivity factor to live in a city, just to cope and survive.

the sex drive thing, i guess when i get older, i will care less about it, and concentrate on other things, like meditation. Same thing with the aggressivity thing, I guess…

When i was doing the veggie diet, i was also trying meditation and really, if you want to meditate effectively is essential to follow a veggie diet, nothing else will do.

My conclusion is that right now, i can´t follow a veggie diet as such, but at some point in my future I will.

Ah, could simply be that of those tested those with the higher IQ scores chose to be vegetarian.

Could be, “smart” people see the benefits of healthy eating habits. Duh.

Sadly, they’re all still within the “average” IQ range, in which a 5 point difference is really pretty meaningless.

Re: #42246, by chartoo
    The diet so rich in bullshit that adults feed kids does them decidedly more harm than a little beef.

I have been an ovo-lacto(eggs, milk products, along with whole grains, beans, vegetables and fruits)vegetarian since 1996, when my husband could no longer eat meat.  So when people who eat chicken or fish are considered vegetarian; there’s something wrong with the definition.  Obviously, a study comparing humans who restrict meat choices to chicken and fish and not other choices and people who follow a more stricter vegetarian is a study in other than nutrition.  While valuable, let’s consider what is being studied.

Voila!  Men are smarter than women.  This stupid ass “study” proves it!  As a Dr. Dr. who has done thousands of “studies” in my lifetime, I can attest: you can get any stupid ass study to prove anything you want to prove.  Even more striking, you can convince just about everyone to buy the results.  After I’m appointed God, I’m going to have it written into my Bible that “studies” are a mortal sin and send people who do them straight to Hell.

It gives an all-new meaning to the familiar saw: “Where’s the beef?”  Not in your brains, evidently ...
