"Scientists studying kidney-stone diseases have stumbled across evidence that humans may be genetically more suited to vegetarianism than meat eating.<br><br><br><br>
The discovery was made when the placement of an enzyme known as AGT, which is linked to the rare kidney-stone disease PH1, was found in one area of the liver in herbivores and another in carnivores, Professor Chris Danpure, of University College London, said yesterday.<br><br><br><br>
Evolutionary science indicated that about 10 million years ago the distribution of the enzyme in human ancestors appeared to change from favouring a omnivorous diet to plant eating.<br><br><br><br>
Humans began eating meat only in the past 100,000 years, a habit which has increased dramatically in recent times.<br><br><br><br>
"It would appear that the diet we have now is incompatible with the distribution of this enzyme, which was designed for a herbivore diet, not meat eating," he said.<br><br><br><br>
The human placement of the enzyme was the same as in rabbits, sheep and horses.<br><br><br><br>
"One of the consequences of this could be the high frequency of kidney stones in humans, especially in western societies."<br><br><br><br>
Danpure, who is a guest speaker at the annual Queenstown Molecular Biology Meeting this week, said if the link was proven it had potential for identifying people susceptible to kidney-stone diseases.<br><br><br><br>
More than 300 leading scientists from New Zealand and overseas are attending the conference this week, which was opened by Research, Science and Technology Minister Steve Maharey on Tuesday night.<br><br><br><br>
Molecular biology was helping transform the New Zealand economy and a recent survey found that biotechnology income to New Zealand companies in 2005 was $855 million, he told delegates. "

Maybe it the eggs, and dairy?

Or simply the fact that being vegetarian reduces your chances of kidney stones, but does not guarentee that you will not get kidney stones. Also, kidney stones probably don't have a single cause.

Yup, there are multiple causes of kidney stones. Eating meat is just one. Genetics (such as a disease caused cystinuria) can be another cause.

Humans have only been humans - Homo sapiens sapiens - for about 130,000 years, so we've been omnivores for as about as long as we've been humans. Evidence suggests we've had a much harder time adapting to the civilized diet (high in grains, only about 10,000 years) than the non-civilized (and omnivorous) diet of the hunter-gatherer (which is usually mostly plants, btw).

Also our teeth say alot as well, they are not made to rip flesh they are fashioned to crush nuts, seeds, and plantlife. Also the cholesterol thing, our bodies cannot handle cholesterol at all, it is like we were not made to consume it.

Yeah, in my case, I think it's probably genetics because my non-veg Dad has a big problem with kidney stones. My doc says that he doesn't see any difference between veg/non-veg and getting the stones. We need more evidence...

Yeah, there definately could be other causes of kidney stones, including genetics. I know that both dehydration (a co-worker of mine used to get kidney stones when he was doing weight control for wrestling), and caffene intake (which could be related to dehydration) can cause kidney stones.

I think that humans as they are today were probably designed to be omnivores. I know the biggest defense you hear from the omnis is " I have canine teeth, etc" I don't think that genetics are much of an excuse for eating meat. I feel like humans are intelligent enough to choose to do what's best for themselves and the world.
