Meat, Proper Diet, Cancer

Posted by Confused on September 30, 2003 at 11:06:54:

Hi Dr. Stoll,

I am really getting confused on what the optimum diet is for a human being. I found the article below on meat. Now, with everything I have read I believe that the best diet is high in leafy vegetables, low in root vegetables, beans, fruit, no grains, no "red" meats, or dairy products and moderate in fish, poultry and eggs.

What do you think? Would the above diet provide enough vitamins, minerals, enzymes, etc.?

Molecule Found in Meat, Milk and Tumors - Study
Mon Sep 29, 5:22 PM ET Add Top Stories - Reuters to My Yahoo!

By Maggie Fox, Health and Science Correspondent

WASHINGTON (Reuters) - A non-human molecule found in red meat and milk makes its way into the human system when eaten -- and seems to build up especially in tumors, U.S. researchers reported on Monday.

The compound, called sialic acid, is found on the surfaces of animal cells but is not found in people, and may be one reason why animal-to-human organ and tissue transplants do not work well. Animals have a version called Neu5Gc, while humans carry Neu5Ac.


But researchers at the University of California San Diego found it does show up in the human body, and showed it can be absorbed from eating red meat and milk.


They also showed that the body produces an immune response against the molecule.


Dr. Ajit Varki and colleagues, reporting in the Proceedings of the National Academy of Sciences (news - web sites), say it is too soon to make any recommendations based on their findings.


"Of course, there are already existing recommendations that people should not consume too much food containing saturated fats, such as dairy products and red meats," Varki said in a statement.


"The highest amount (of Neu5Gc) was found in lamb, pork, and beef (so-called 'red meat')," the researchers wrote. Levels were very low or undetectable in poultry and fish, vegetables and hen's eggs.


Varki, who is not a vegetarian, noted that many studies have linked a diet rich in meat and milk with cancer, heart disease and other diseases.


AUTOIMMUNE DISEASE


"The small amounts of Neu5Gc in normal tissues also raise the possibility that anti-Neu5Gc antibodies are involved in autoimmunity," the researchers said.


Autoimmune disease occur when the body mistakenly attacks healthy tissue and include type-1 or juvenile diabetes and some types of arthritis. "In this regard, it is interesting that vegetarian diet has been suggested to improve rheumatoid arthritis," they wrote.


But much research has focused on the fat content of animal fat or byproducts of cooking meat as the cause of disease.


Varki's collaborator Dr. Elaine Muchmore developed an antibody -- an immune system targeting protein -- that would hook onto Neu5Gc. The team found Neu5Gc in human tumor samples and to a much lower degree in healthy tissue.


More tests showed that most people had made their own antibodies that recognized Neu5Gc, and thus could potentially initiate an inflammatory immune response.


Varki and two colleagues drank Neu5Gc purified from pork sources, and the molecule showed up in their urine, blood, hair and saliva.


"We need to find out if there is any association between the presence of Neu5Gc and/or the anti-Neu5Gc antibodies with any disease," Varki said. "This will require large-scale population studies."


In some cases the human immune response was similar to that seen when people are exposed to another animal molecule, this one a cell surface molecule called alpha galactose.

Varki noted that the molecule is almost certainly not immediately toxic to people.

"Meat eating has certainly been a feature of human ancestors for many hundreds of thousands of years," he said.

"Thus, it is indeed possible that humans have developed some kind of tolerance or indifference to Neu5Gc. However, most humans are continuing to make antibodies against Neu5Gc."

It could be that the damage only builds up over years -- and that as people live longer, the consequences make themselves felt.

"However, we are now living longer and the question arises whether the gradual accumulation of Neu5Gc and the simultaneous presence of antibodies against could be involved in some diseases of later life," he said.

Confused, Were all different..You have to find what works best for you..For me I find I do better on how I combine foods as opposed to what I eat..Silver Fox!

You are confused because there is no proper diet for a human being. The proper diet is different for every individual.

This is why you hear a certain group swearing by Atkins and yet another group swearing by a vegetarian diet. This is why some people seem to do great on any given diet and others do not.

The optimum diet for you is whatever your metabolism dictates. This is generally believed to be a result of where your ancestors lived and what they ate.

Look up metabolic diet here on this site, and/or go to the link below for other dietary theories...

Think about this quote:
"A non-human molecule found in red meat and milk makes its way into the human system when eaten"

First off, of course! Only cannibals eat human molecules!
Secondly, think about this quote:

"The compound, called sialic acid, is found on the surfaces of animal cells but is not found in people"

But... they DID find this molecule in people!

Consider this: Vitamin C is not found in humans UNLESS we eat food that has Vitamin C already in it. Some animals can manufacture vitamin c in their own bodies, but humans cannot.

Some of the other comments in the article give cause for thought, but my point is that this is an incredibly early finding that raises more questions than it answers.



Confusing, yes! It seems there is so much conflicting info. out there.

Try reading the book by Sally Fallon, Nourishing Traditions. It debunks a lot of what was in that article. It does seem that different diets works for different people. Wouldn't it be nice if it were easy to figure out?! I think about the only thing I think I've figured out so far is that refined anything and sugar products are not good for any human body.

Hi, Confused.

You might look up a book through your lending library "Are You Confused" by Dr. Paavo Airola, published by Health Plus in 1971 with multiple printings thereafter.

Personally I still think that finding the correct diet for any individual has to involve the individual's personal laboratory (their bodymind) to discover what works. I would start with the WFD and then go from there to specific diets that include this basic dietary approach.

Listen to Carol D, Lincoln, Labrat and Steve.

Hope this helps.

Walt

BOttom line is a diet including red meat and milk could possibly cause cancer but it also supplies other vital nutrients. You may end up being defficient in some vitamins and minerals if you cut those foods out. It all depends on your specific body chemistry/metabolism.

Almost all foods can be found to cause some kind of problem but you have to weigh the pros and cons.

Yes. And we have detoxification mechanisms to deal with those. Plants, for example, are well known to have lots of toxins, but anti-meaters don't seem to talk about them.

Thanks, Lincoln.

The part that confused me was that they find a high level of this molecule in tumors, indicating that it is a toxin that your body can't detox and contains it in a tumor cell.

Thanks, everyone for yor replies.

I have to say that I am eating whole foods only and lean towards a diet heavy in red meat right now. I eat a lot of New Zealand beef, more so than poultry and I hate fish. I eat bacon and eggs for breakfast a lot of the time, sometimes sausage, sometimes steak. I get non nitrate/nitrite, non sugar bacon and sausage. Although I don't eat large portions most of the time, I am still eating it every day. So that article concerned me a bit. I was trying the Atkins way of eating and I really love it. My appetite has really been under control and I feel good too.
