My message had nothing to do with support of meateating. It was about B12 and my suspected reasons why her nutritionist recommended meat to her.

Here is some information about plant and vegetable sources of B12.

"Plants & vegetable lack the vitamin B12 unless they have been contaminated by soil microorganisms..." Exerpted from Vol 110/No1/July 2001/Postgraduate Medicine

"...Any vitamin B12 found in plant foods could probably be traced to contamination with micro-organisms contained in manure or, in the case of legumes, to the presence of nitrogen-fixing bacteria in the plant root nodules..." Exerpted from Advanced Nutrition and Human Metabolism

"The only reliable unfortified sources of vitamin B12 are meat, dairy products and eggs. There has been considerable research into possible plant food sources of B12. Fermented soya products, seaweeds and algae have all been proposed as possible sources of B12. However, analysis of fermented soya products, including tempeh, miso, shoyu and tamari, found no significant B12.
Spirulina, an algae available as a dietary supplement in tablet form, and nori, a seaweed, have both appeared to contain significant amounts of B12 after analysis. However, it is thought that this is due to the presence of compounds structurally similar to B12, known as B12 analogues. These cannot be utilised to satisfy dietary needs. Assay methods used to detect B12 are unable to differentiate between B12 and it's analogues, Analysis of possible B12 sources may give false positive results due to the presence of these analogues.
Researchers have suggested that supposed B12 supplements such as spirulina may in fact increase the risk of B12 deficiency disease, as the B12 analogues can compete with B12 and inhibit metabolism.
The current nutritional consensus is that no plant foods can be relied on as a safe source of vitamin B12." Exerpted from Vegetarian Society


If you have credible sources that contradict this information, I would truly love to look at them. It would give me great pleasure to find some information that found plant derived B12 that is bioavailbe to our bodies.
