A recent study from Southampton University indicates that vegetarians have an average IQ that is 5 points higher than that of meat eaters, based on childhood IQ scores. However, the study does not establish a direct cause-and-effect relationship between diet and intelligence. Critics argue that the findings are misleading, as the IQ scores for both groups fall within the average range, and many self-identified vegetarians may consume fish or chicken. Furthermore, the study raises questions about environmental factors and demographics influencing dietary choices and IQ. Overall, the discussion highlights skepticism about the significance and implications of the study's results.

That shouldn't be very surprising. It's much easier to be vegetarian in open-minded and intellectual environments, where smart people often end up. I'd like to see this done with more control for environment.

I think tiger may be right on this one. Good observation :wink:

edit: if this is true, it would mean meat-eaters in the same environment would score just as high

How do we explain why vegans scored an average 10 points lower than average on IQ tests?

You can't be very smart to choose a completely vegan diet? :biggrin:

That's because Vegans are idiots. Your standard vegetarian probably has a good idea of what is being given up and how it should be replaced. Carbs from pasta, protein from beans, fats are everywhere, most vegetables count as fibre, most vegetables contain vitamins, milk has lots of good stuff in it. Completely balanced. To become a vegan you need to throw common sense out the window and decide that you would rather get your calcium from a bunch of pills instead of drinking a glass of milk. Or in some cases, not at all. Do a google search for "osteoporosis vegans".

Thanks, dude.
W is Cree, from near Lloyd, and you should see her gnaw through a rack of ribs. She gets those dentures going like a buzz-saw. I'm pretty sure that she actually has a rotary joint in her jaw, but it moves too fast for me to prove it.

Speaking of corn fed and the connection to E. coli.

http://www.sciencemag.org/cgi/content/abstract/281/5383/1666

The gastric stomach of humans is a barrier to food-borne pathogens, but Escherichia coli can survive at pH 2.0 if it is grown under mildly acidic conditions. Cattle are a natural reservoir for pathogenic E. coli, and cattle fed mostly grain had lower colonic pH and more acid-resistant E. coli than cattle fed only hay. On the basis of numbers and survival after acid shock, cattle that were fed grain had 106-fold more acid-resistant E. coli than cattle fed hay, but a brief period of hay feeding decreased the acid-resistant count substantially.

So because of the greed of the cattle industry, and the ignorance of the average meat eater, we all must suffer.

Here is a study of corn fed -vs- barley.

http://www.ncbi.nlm.nih.gov/entrez/...ve&db=PubMed&list_uids=15083716&dopt=Abstract

There is a petition by the UCS to the USDA, asking that they raise the standard for grass fed beef from 80% to 99%.

Here is another good article about grain fed cattle and the acid resistant E. coli.

http://www.sciencedaily.com/releases/1998/09/980911075347.htm

In studies performed at Cornell, beef cattle fed grain-based rations typical of commercial feedlots had 1 million acid-resistant E. coli, per gram of feces, and dairy cattle fed only 60 percent grain also had high numbers of acid-resistant bacteria. In each case, the high counts could be explained by grain fermentation in the intestines.

By comparison, cattle fed hay or grass had only acid-sensitive E. coli, and these bacteria were destroyed by an "acid shock" that mimicked the human stomach, the microbiologists report in Science.
And then how about the cows themselves.

http://www.foodrevolution.org/grassfedbeef.htm

Author and small-scale cattleman Michael Pollan wrote recently in the New York Times about what happens to cows when they are taken off of pastures and put into feedlots and fed grain:

"Perhaps the most serious thing that can go wrong with a ruminant on corn is feedlot bloat. The rumen is always producing copious amounts of gas, which is normally expelled by belching during rumination. But when the diet contains too much starch and too little roughage, rumination all but stops, and a layer of foamy slime that can trap gas forms in the rumen. The rumen inflates like a balloon, pressing against the animal's lungs. Unless action is promptly taken to relieve the pressure (usually by forcing a hose down the animal's esophagus), the cow suffocates.

A corn diet can also give a cow acidosis. Unlike that in our own highly acidic stomachs, the normal pH of a rumen is neutral. Corn makes it unnaturally acidic, however, causing a kind of bovine heartburn, which in some cases can kill the animal but usually just makes it sick. Acidotic animals go off their feed, pant and salivate excessively, paw at their bellies and eat dirt. The condition can lead to diarrhea, ulcers, bloat, liver disease and a general weakening of the immune system that leaves the animal vulnerable to everything from pneumonia to feedlot polio."
All this is not only unnatural and dangerous for the cows. It also has profound consequences for us. Feedlot beef as we know it today would be impossible if it weren't for the routine and continual feeding of antibiotics to these animals. This leads directly and inexorably to the development of antibiotic-resistant bacteria. These are the new "superbugs" that are increasingly rendering our "miracle drugs" ineffective.

So what is the produce industries plan to cope with the problem created by the cattle industry?

http://www.sfgate.com/cgi-bin/artic...N291V1.DTL&hw=glen+martin+coli&sn=001&sc=1000

The recent scares over deadly bacteria in California produce may hurt farm programs aimed at restoring wildlife habitat and cutting water pollution.

Such environmental programs could be at odds with "clean farming techniques" promoted by food processors. Those techniques encourage growers to remove grassy areas that are planted to reduce erosion and trap pesticides before they reach waterways. The practices also discourage habitat zones that might attract animals that carry bacteria like E. coli or salmonella.

I guess we need to sterilize the entire planet and only keep those species that we like to eat.

I think a better solution is to stop fighting nature and learn to live more harmoniously in the natural world.

That is easy. The first thing is to take the point in context. Your conclusion was just a matter of emphasis. Sometime sknown as "observer bias."

Among those who had taken vegetarianism to its logical conclusion (“gone the whole hog,” as it were) and become vegan (no animal products), mean IQ scores were lower.On average, vegans had a childhood IQ score that was nearly 10 points lower than other vegetarians: mean (SD) IQ score 95.1 (14.8) in vegans compared with 104.8 (14.1) in other vegetarians (P = 0.04), although this estimate must be viewed with caution as only nine participants were vegan.

See the difference in emphasis:

I know many vegans, most of them are quite intelligent professionals. They are learned on many subects and fascinating to talk to.

I also know many people that are are vegan for reasons of compassion who do not really have a clue.

Idiocy is not the realm of diet. If you wish to make such an offensive ad hominem attack you should provide some evidence to support your point.

Your standard vegetarian probably has a good idea of what is being given up and how it should be replaced. Carbs from pasta, protein from beans, fats are everywhere, most vegetables count as fibre, most vegetables contain vitamins, milk has lots of good stuff in it. Completely balanced. To become a vegan you need to throw common sense out the window and decide that you would rather get your calcium from a bunch of pills instead of drinking a glass of milk. Or in some cases, not at all. Do a google search for "osteoporosis vegans".

The rest of your statement just supports my suspicion that you are quite ignorant about nutrition.

To start with you do not get carbs from meat, so this point is meaningless.

Protein comes from many other sources than beans. The best sources, with the fewest side effects (heart disease, cancer, diabetes, etc.) are green leafy vegetables. Kale anyone?

You do not get vitamins from meat. The best source of vitamins are plants. Isn't it convenient for us that we have a digestive system specifically evolved to digest plants.

Milk does not have a lot of good things in it. More than half of it's calories come from saturated fats. It has some riboflavin, calcium, and vitamin A, however since 7 out of 10 people are lactose intolerant, I think we can get these nutrients from better (plant based) sources.

I took your google suggestion.

Here was the first hit.

When we eat beef, pork, lamb, chicken, or other foods from animals, our bodies take in proteins that may be rich in sulfur. That's unlike the proteins in plant foods—fruits, veggies, nuts, grains, or legumes like peas or dry beans. As we digest animal proteins, the sulfur in them forms acid. A slight, temporary acid overload—called acidosis—may result.


To regain our natural balance of acidity to alkalinity, or pH, in the bloodstream, our bodies must buffer the influx of acid. One possible buffer is calcium phosphate, which the body can
borrow from our bones—the body's main storage depot for this essential mineral.

From the same USDA study.

Less Bone Formed


But two findings were unexpected. First, bone resorption—in which calcium is taken away from bones via the bloodstream—was the same for omnivore women as for vegan women.


"The current model predicts increased bone resorption for people who consume large amounts of animal protein, so it was somewhat surprising that bone resorption was the same for both groups of our volunteers," Van Loan notes.


Second, bone formation was significantly less in omnivore women than in vegan women. This happened even though the omnivore women had a higher calcium intake than did the vegan volunteers. (The volunteers did not differ in their intake of other nutrients that affect bone health, such as magnesium.)


Using the model as a basis, "one would not have predicted a significantly greater amount of bone formation for vegan volunteers than for omnivore volunteers," Van Loan adds.


The implication for people who eat high amounts of animal protein may be important: Specifically, over time, the net effect of a lower amount of bone formation would likely be a decrease in bone density. Explains Van Loan, "If you have less bone formation, the result is the same as if you had an increase in bone resorption. So, even though bone resorption was the same in both groups of volunteers, the lower amount of bone formation in the omnivore women could lead to a decrease in their bone density."

Since bone is metabolically more active than muscle, I think that physical activity may play a more important role than diet. Vegans are generally more active, especially in their later years than meat eaters.

I found the study to be quite silly. I don't mind the teasing, it gives me the opportunity to share some of the knowledge and information I acquired during my journey to becoming vegan.

BTW the healthiest diet is one where 10% or less of ones calories are derived from animal foods. You mentioned to me once that you eat meat only occasionally. I think you are probably destined for a long and healthy life. :smile:

The problem most unhealthy vegans have is:

1) Access to convenient healthy vegan food.

2) The same problem that most meat eaters have, ignorance of nutrition in general.

[edit]As to the teasing, I actually started it with the OP. So turnabout is fair play. [/edit]

Some people stop eating meat, because of cholesterol. That doesn't neccessarily make a person smarter than meat eaters, but it might make a person live longer. Some might rather die than live without meat. Some have more important reasons to live.

We evolved as omnivores and our bodies are optimized for a hunter-gatherer diet. Before agrarian societies developed, and some people stayed tied to the land, with facilities for storing food (granaries, etc), the availability of vegetables and grain as food was not very reliable. Anybody who would not eat mammals, fish, birds, amphibians and insects, as well as the eggs and larvae of such would probably not have survived. At the least, their need for protein and some minerals and other nutrients would not have been met, putting them a disadvantage.

The Inuit have survived for many generations on a diet that is predominantly meat, fat, and fish, with blueberries and other vegetable additions as available. Until recently, with the introduction of foods from our western/temperate diet, they had a very low incidence of arteriosclerosis and other diseases we usually associate with a high-fat diet. Depending on where they live and what is available as prey, they may eat mostly fish or mostly marine mammals, caribou, etc. The common factor in their diet is that until recently, vegetables were very scarce and only available seasonally.

Also, don't forget that meat obtained from hunting wild animals is often much leaner than that obtained from farm-raised animals, so if you're eating what you hunt, you can avoid a lot of the problems that come from eating very fat, farm-raised animals. Of course, the farm-raised animals are bred that way because that's what the consumer prefers. In some animals, like pigs, more demand for leaner meats have spurred on a shift in the breeding practices to produce leaner animals (though, there's also still plenty of a market for the fatty versions). It's not meat, per se, that's the problem, but overconsumption of the fat in the meat (and overconsumption of food in general).

I don't really like the need to apply a label to oneself. People seem to take great pride in the fact that they eat absolutely ZERO meat or ZERO animal-derived products, and that ANY meat-eating is bad.

I personally don't eat red meat more than once a month (mostly because I'm not a big fan of the taste/texture), and I probably eat poultry/fish 1-2 times per week. I think this is a rather healthy balance, yet it doesn't really fall under any specific dietary category. My diet is better than the average person's diet, and less things die because of my infrequent meat-eating; however, since I can't really label myself as a "vegetarian," I'm lumped in with my fellow carnivores. There's just so much pride in these sorts of lifestyle choices that people champion the label to make themselves feel righteous.
