Hi David,
I'm an ex vegetarian of sorts as I did eat eggs, milk products and occasional fish. That's probably why I survived. Their fantasies about b12 and so on were very detrimental. I could feel the differences of no meat the very first day. The explanation I was given over and over was "toxins" leaving my system. Yup, toxins like l-carnitine and b12. Now I know it was vitality and health leaking out of my system.
Of course vegetarians feel mb12 and adb12 strongly, they are very deficient. Then they misinterpret the startup symptoms and become frightened of them.

hi Freddd, I read through the long vegetarian post of post 355 (
http://www.veganforum.com/forums/showthread.php?t=169) and the only concerning issue that i see is the supposed increased cancer rates with high b12 and chronic myelogenous leukemia. I have heard about the cancer issue before. However, some of the information quoted in the threade is blatantly incorrect and misleading. The cause and effect of the b12 is not made clear. "b12 higher in patients with.... " could imply in truth that the cancer is causing liver dysfunction, for example, and a release of b12 into the serum, or that b12 is not being absorbed by the tissues. They also do not specify the type of b12 used in the case studies.
My other point about this veggie thread is that several of the posters try b12 and then back off due to dizziness, nausea, etc. Startup symptoms that I had when starting on the b12 program. It is sad, that most of the people are b12 deficient and they don't recognize it.
1. For example,
"Cases of increased cancer production in animals receiving high levels of B12 have been published. A group of French investigators reported a series of cases suggesting that B12 may stimulate multiplication of cancer cells and aggravate the disease. Patients with rheumatoid arthritis present serum B12 levels significantly higher than normal subjects. It is also known to be higher in patients with ulcerative colitis, leukemia and other serious illnesses. Breast-fed infants get only a tiny fraction of a microgram of B12 per day, even if their mothers are on a high intake. Yet, they can build neurological tissue, convert their hemoglobin from F to A type, and do other complex functions dependent on B12. Iron deficiency interferes with absorption of B12."
2. Some other quotes by the Admn of the site:
"And, to stick to the topic of the thread: I know of several people who have had cancer. In my past/naivity I suggested for these people to check their B12 levels and take supplements, after having heard that B12 overdose is never a problem, and that too little B12 was associated with various health risks, including some cancer types. When these people discussed taking B12 supplements with their doctors and their hospitals, they response was much more negative than positive. I'm not saying that we should trust most doctors or most hospitals, but these people seemed to be informed about the possible link between too much B12 and exaggerated/rapid cancer cell growth/division."
3. and
"Is B12 part of it? After all, B12 is about growth and cell division, among other things; it is necessary for the rapid synthesis of DNA during cell division. Cancer = abnormal and uncontrolled cell division."
4. and again, here no specific causal effect is given. Meat also has a lot of protein, so does protein cause cancer?
"We have another thread about cancer, but since B12 is THE nutrient that we know there is more of in meat than in plants, and high meat intake is associated with increased cancer risk, I'm posting a few more links about the meat/cancer link:

Eating Lots of Meat Can Increase
Cancer Risk"
5.and this one...
"In animals studies, there have been cases of increased cancer production in animals receiving high levels of B-12. It has been noted that the animals have an increased production of white blood cells such as occurs in chronic myelogenous leukemia. A case has been reported of acute myeloblastic leukemia resulting from B-12 overdose in the treatment of pernicious anemia."
6. Once again cause and effect are backwards on this one. b12 has been released by the liver due to damage, not b12 causing whatever....
"High levels of Vit B12 in the system also have been found to result in increased methyl mercury concentrations in the liver and brain(51). Methyl mercury is 10 times more potent in causing genetic damage than any other known chemical (Ramel, in(35)), and also crosses the blood-brain barrier readily. "
