Posted - 08/15/2005 : 08:18:17 Just found this article on the BBC website about the possibility of growing meat in a lab for consumption. I would be really interested to hear what everyones views were on this?
Personally it really creeps me out.
Putting the issues of cloning and genetic modification of foodstuffs aside for a second I have a Question for the Vegies on this board.
Do you think you could ever eat manufactured meat knowing that its based on a single animal even if it didn't suffer in the process? Say for example the cells to be cloned in the final product () were taken without harming the animal in any way.
I imagine that if manufactured meat was ever to become the norm the human race would eventually detach itself from what it actually is.
Soylent Green anyone?

Scientists aim for lab-grown meat
Pork cuts could come fresh from the lab An international research team has proposed new techniques that may lead to the mass production of meat reared not on the farm, but in the laboratory.
Developments in tissue engineering mean that cells taken from animals could be grown directly into meat in a laboratory, the researchers say.
Scientists believe the technology already exists to directly grow processed meat like a chicken nugget.
The technology could benefit both humans and the environment.
"With a single cell, you could theoretically produce the world's annual meat supply. And you could do it in a way that's better for the environment and human health.
"In the long term, this is a very feasible idea," said Jason Matheny of the University of Maryland, part of the team whose research has been published in the Tissue Engineering journal.
Growing the meat without the animal could reduce the need to keep millions of animals in cramped conditions and would lessen the damage caused by the meat production to the environment.
Laboratory-grown meat could also be healthier, proponents say.
Eating 'mush'
Tissue engineering techniques were first developed for medical use and small amounts of edible fish tissue have been grown in research conducted by Nasa.
Concerns have been raised about eating meat from cloned animals. To industrialise the process, researchers suggest the cells could be grown on large sheets that would need to be stretched to provide the 'exercise' for the growing muscles.
"If you didn't stretch them, it would be like eating mush," said Mr Methany.
Whilst the technology to produce processed meat is here now, producing a steak or chicken breast is still quite a way off, the researchers say.
Questions
The new techniques could also provide a dilemma for vegetarians.
Some may feel able to eat meat that has been grown without an animal being harmed.
Others feel that question marks remain about the way the cells would be taken from animals.
"It won't appeal to someone who gave up meat because they think it's morally wrong to eat flesh or someone who doesn't want to eat anything unnatural," Kerry Bennett of the UK Vegetarian Society told the Guardian newspaper.
How regulators might react is also unclear.
The US Food and Drug Administration has asked companies not to market any products that involve cloned animals until their safety has been evaluated.

That's the point! You wouldn't want to live to that age if you were an unhealthy mess! But according to Dr. Walker, in his old age he felt like he was still 30. Here's a quote: "I can truthfully say that I am never conscious of my age. Since I reached maturity, I have never been aware of being any older, and I can say, without equivocation or mental reservation, that I feel more alive, alert, and full of enthusiasm today than I did when I was 30 years old. I still feel my best years are ahead of me. I never think of birthdays, nor do I celebrate them. Today I can truthfully say that I am enjoying vibrant health, I don't mind telling people how old I am: I AM AGELESS!"
Darwin, are you sure the oldest person ever was 122? There's a women in my town who is well into her 100's (I want to think 110, but I'm not positive at the moment). And I've read in a book about a man meeting someone in Germany who was supposedly 143 years old (obviously his age couldn't be proven, so it might not necessarily be correct).
I'm not positive that Dr. Walker was 118 exactly. He was definitely well into his 100s without a doubt, but I don't think anyone knows EXACTLY how old, but I've read from many sources that he was 118 when he died.
ˇViva los Católicos! http://adrianfoster.dmusic.com/
I'm not sure what the oldest age is, but somewhere on the always reliable internet 122 was given.
On Dr. Walker, I did see one page that claimed that it use to be said that he lived to his 130s. And, the page also claims that the Social Security Death Index has no record for a Walker dying the year he died that was as old as 118. So, some people are skeptical. |

Well, I would say using sloppy language (being anthropomorphic by saying atoms or enzymes are dead, or enzymes contain 'life principle') is sloppy science.
Also, color me a skeptic but I don't believe the guy lived for 118 years. The oldest modern person ever may have been about 122 years, but documentation is sketchy and that was a woman. I don't have any evidence to refute the claim, but I don't believe it.
I've also found a number of sites that refute this live enzyme idea, but I don't think I can claim that they are unbiased or more scientific.

Posted - 08/16/2005 : 11:37:49 ...and you're giggling because I said "dead."
Anyways, yes, he has been dead a while, I don't believe there's any more recent research that contradicts anything he's said (unless the 20 amino acids thing is a very recent development) and yes, there are at least three people here who know a HEEEEEELLLLL of a lot more about science than I do (I nearly failed high school biology), but I'm sorry, I don't see anything that you or anyone else here has written that contradicts anything Dr. Walker or other proponents of a raw-food diet have written. I don't blindly put faith into what food dr.'s, gurus, and faddists write. I believe what makes the most sense. When I read, for example, Dr. Walker's books, I see information about how our digestive system works and how the food we eat affects it that couldn't be more clear, and I see a guy that researched this for 70 years (which is far more than you or I or anyone here has researched it) and lived to be 118 YEARS OLD on this diet, which is a clear enough indication that it WORKS, and I see (and know personally) many, many people who are following these same guidelines for their diets and achieving the same amazing results, and I have evidence from MY OWN LIFE, that when I cut meat out of my diet and do my best to avoid processed and cooked foods (and I'm not very good at avoiding them, but when I do...) and drink freshly extracted vegetable juices each day, I have enormous vigor, no fatigue, no sickness, and extraordinary health.

Posted - 08/16/2005 : 11:33:25 Just a quick note on amino acids. The only amino acids found in proteins and enzymes are a-amino acids, of which there are twenty. This website gives a nice representation of them, what's essential etc http://www.johnkyrk.com/aminoacid.html
There are also amino acids called D-amino acids which are, I think, of the opposite handedness to alpha amino acids. These have been found in nature in the occasional polypeptide, but not in proteins or enzymes. Search google for more info, but there are far more than three.

Posted - 08/16/2005 : 11:17:17 Dr Walker and yourself have both said that breaking down proteins is a waste of energy, so it follows that we should not break them down and use them as they are. You've said that dead enzymes (sorry I can't write that without giggling, it's tickled me) are gained when you cook food and dead enzymes are no good, which again follows the thought that enzymes are used as is.
I've just googled Dr Walker and it seems he's been dead 20 odd years, I really don't mean to be rude but things and understanding of things has moved on since then.
A good number of people put a lot of faith into these food Dr's and it depresses me to see people believe it absolutely. Carbs are bad for your body, meat will kill you, I'm fat because it's in my genes... it's just another thing to believe and isn't always right. I'm not accusing you of this, but you've got three science bods here telling you it's hokey, I'm not sure we've got seventy years of understanding between us but we do have *current* understanding, which is different. It's been a while since I looked into metabolism but I can see the basics from these quotes are well off. In thinking terms, as soon as you use the word life or alive or live to describe enzymes you've stepped into the regions of weird and wrong.
Think of it like this, you know those lego kits you got as a kid? you could use all the blocks of lego to make a spaceship, you'd zoom it around and play with it like a spaceship. If you gave the spaceship to your kid sister she probably wouldn't want a spaceship so she'd take it apart and make a house. Enzymes is the same, the function as they are until not wanted and then are broken down to the building blocks (amino acids) and reformed into something that is wanted. There is no live or dead, an enzyme when it's not active is like a spaceship thats being taken apart, it could still be the spaceship if it wants to be or it could be a house if thats better.
I hope that doesn't sound weird??

I don't know Dr Walker but I know something iffy when I read it, and thats damned iffy. If people were truly interested in the science of what they eat and how it used it wouldn't do them harm to have a look at a few metabolic pathways and see what goes where and does what. This, to my eye, is another cashing in on the obsession of food with scientific groundings that are at best wobbly.
It could be more scientific by being right, that Atkins guy was a Dr too and an absolute disaster his science turned out to be.

I don't see how it could possibly be any more scientific. What Llama just said confirmed what I said, that enzymes are functional ("alive," I'm sorry if that term isn't scientific enough for you) until they become denatured, which is caused by too much heat--to be exact, heat above 122 degrees Farenheight (and I'm sure, as you said, this is slightly different for some enzymes and some enzymes are resistent to heat. I'm not denying this.) But bottom-line, Dr. Walker's findings are VERY MUCH scientific and NOT a bunch of new age phooey.

No, he never said that. He said the "life-principle," or enzymes, die.
quote: The importance of VITALITY in the atoms composing the amino acids can best be appreciated by realizing that within 6 minutes after life leaves the body all the atoms in the body cease to be live, organic atoms, and their function and activity consequently comes to a stop. So long as life is present in the body, the live atoms therein have the vital spark of life which enables them to carry on their work.
He did say that atoms die.
Being functional is not interchangeable with being alive. Enzymes are not alive, they are functional, until they are denatured.
Honestly, the whole use of the phrases 'life force' and 'life principle' is wholly misguided. He could have called it the 'sandwich' and it would have made more sense

Unless you're going to stop quoting food gurus at me and start looking at the science of this we're not going to get anywhere. I'm serious, enzymes are proteins that act as catalysts to make reactions go facster. If human beings, as with all living things, did not produce enzymes they would never exist in the first place. We can not use enzymes ingested directly from food in the state that they are in because they are incompatible with out metabolic processes so we break them down to the constituent components, as in the amino acids, to reform enzymes that are present in our normal pathways. It matter not a bit if you eat food raw or cooked in terms of enzymes because chances are they get broken down anyway. If you've ever worked with enzymes you can watch activation using colormetric photospec assays, you heat inactivate proteins but that does not mean you kill off everything that makes an enzyme, it means you unfold it and in it's unfolded state they can not work, but if you were to re-fold it it would work exactly the same way as it did before it was inactivated. Also, there are enzymes that are not heat inactivated there are some that are remakably resistant to this found in hot springs and volcano mouths so to generalise like that is innapropriate.
Could you explain this "life principle" to me then, because I can't see any sense in it.
But please, none of the DEAD stuff, I'm horribly giggly as it is.
