Martin318is said:How about instead of going the route we are, and presenting false informatino such as randomness of B12 ingestion, we try and actually talk about the question - how can a vegan diet provide sufficient B12 for an ordinary person without supplementation?
Polyarmour said:Plant eating animals get their B12 from ingesting bacteria that live in the soil. That is, when they eat plant matter they take in a small amount of soil with it which contains the B12 producing bacteria. That's where it comes from, it doesn't just magically appear in animal flesh. If humans ate unwashed vegetables and plants it would have the same effect. But we don't do that anymore. We sterilise the hell out of it before ingesting it. So supplements are required to make up for the lack of dirt on our food.
Rip:30 said:Totally incorrect.
Ruminants get most their B12 from their gut bacteria. Washing veggies has no effect.
Polyarmour said:There was a study on vegan Hindus who do not suffer from B12 deficiency that concluded they obtained their B12 from small insects, larvae, faeces, residue left on the plant food they consumed.
BroDeal said:Oh, yeah. That will convince a lot of people to become vegans. You cannot eat animals but
small insects, larvae, and faeces are a-okay.
durianrider said:When people say 'you cant be a vegan cos you get a b12 deficiency' its like saying 'you cant ride a bicycle cos you will get a flat tyre so you should drive a car, truck or catch a bus like everyone else!'.
Cos ONLY bicycles get flat tyres right?
Cos ONLY vegans have b12 issues right?
Ive been a 'tour guide' for the last 7 January's in Adelaide during Tour Down Under and in recent years Ive asked various riders, team doctors, team assistants etc if they use B12 injections and 100% of those asked, said 'yes, this is normal'.
So what is peoples reply to this then? If b12 deficiency is ONLY found in vegans, how come your heroes on wheels are taking them? How come when one browses on running/bodybuilding forums and types 'b12' into the search function, it comes up with pages of stuff? Even at 'getbig.com' they rate b12 injections. http://www.getbig.com/articles/faq-vit1.htm How come bodybuiders eat so much animal stuff yet they also use the most b12/protein/zinc supps of any demographic group? Dont believe me, go ask the 6ft bicep standing in the corner of your local gym.
How come? Cos 39% of the US has a b12 deficiency. http://www.ars.usda.gov/is/pr/2000/000802.htm
Japan has a minimum cut off of 550. In Australia/US its around 150. So you can be 'ok' at home but if you live in Japan, you are 'chronically deficient'. Brings a new term to the meaning 'Ive got enough b12 cos the doc said so'.
Read the book 'could it be B12' by Sally Pacholok and I challenge anyone not to be concerned about your current b12 levels REGARDLESS of what you eat.
Hey, Im riding the fastest of my life. Rode a 14:06 up Norton Summit. Been vegan 10 years last week and also ran the fastest half marathon of my life. Guess who is in 8th.http://www.sarrc.asn.au/images/event_results/Clare Final Results11.pdf
My b12 level hovers between 800-1400. My homocysteine is around 6-8. My haemoglobin is around 147-155. What levels do others have here? Google 'vegan blood tests' if you want to see em on youtube.
How do you know your diet is working if your blood tests and drug free performances aint supporting it? Thats something to think about.
I gave a health & fitness talk to 160 people recently in Melbourne. Here is a brief vid.

Congratulations, Flash. I've got ten years on you and I can run the same time...fueled by dead animals.Been vegan 10 years last week and also ran the fastest half marathon of my life. Guess who is in 8th.![]()

lostintime said:The verbal mas-debation goes on and on .....
Some don't want to believe they can be eating animal foods and still be deficient in B12.
Some don't want to believe they can be vegan and be deficient in B12.
The bottom line is there is no ultimate ... definitive answer to the B12 question. It all comes down to beliefs. Choose whatever you wish. . . . but don't think you're somehow superior because you eat animal stuff or not. We're all beings having a human experience. Nobody really knows jack ...... and that's for sure![]()
Rip:30 said:Belief has nothing to do with B12 deficiencies. Saying nobody really knows is completely ridiculous, there's decades of peer reviewed literature out there. As I keep stating, there are several causes of B12 deficiency--not eating any B12 is one of them (ig vegan diet). It's not that confusing.
No one's saying you can't be vegan, just pointing out the fact that vegan diets lack an essential nutrient, unless you include feces. Obviously you can easily overcome this with supplements. My original reason for making this point was to highlight that humans did not evolve on a vegan diet, as someone tried to suggest.
Martin318is said:Got to admit, I am pretty disappointed that this is what you chose to come back with after all that time to think of a reply to the information that was posted. The article that was posted indicated that you personally had the lowest B12 level they had clinically tested.
The questions therefore - ignoring silly things like referencing bodybuilders etc - are:
1) how do you explain YOUR low B12? and
2) how does a vegan ensure they are keeping their own level of B12 sufficiently high - WIHTOUT supplementation?
lostintime said:I respect your opinion.... but don't agree at all. There are so many opinions .... and that's all a peer review is .... it makes the head spin.
Yes.. you can be a vegan and not be B12 deficient .. and not take supplements. Forward to the 6:00 minute mark ..... if you feel like it.
http://renegadehealth.com/blog/2010...ve-and-painful-teeth-with-dr-jameth-sheridan/
Even if one does take B12 supplements .... the benefits far outweigh any perceived hit to the ego.
Man has evolved .... we've evolved so far we no longer need to eat animal foods if we choose. Just because grandpa and some of his descendants ate animal foods doesn't mean I must. I think the world will continue to evolve just fine.
durianrider said:What are people doing here to ensure their b12 is high enough so they have sufficient red blood cell formation etc?
durianrider said:1. Well with my levels around 800-1400,I dont have any b12 issues anymore and how come Im the only one here with bloodtests on youtube proving so lol!?
What are people doing here to ensure their b12 is high enough so they have sufficient red blood cell formation etc? Anyone got any levels to share with me? What are people here doing to lower their homocysteine? Anyone?
2. Its the same question for ANYONE regardless of diet. Why? Well how do we explain the low levels in the tests like the Framingham study etc that showed meat eaters having low b12 serum levels and elevated homocysteine? Interesting. So thinking you can eat dead animals and be fine with your b12/homocysteine is like thinking because you wear a seatbelt that you wont have an accident.
Something to think about..
After that TV show I did more tests. Turns out I lack intrinsic factor. Turns out thats got nothing to do with a deficiency of dead animals on my plate. Turns out I could have died or had some serious issues if I didnt find this out. So yeah, being vegan has saved my life in a few clinical instances. Same for many others too.
Rip:30 said:Why do you guys keep posting links that don't support your position?
From the video you just posted: "I've never met a long time fruitarian who is healthy who didn't cheat". He then goes on to suggest bacterial sources of B12 supplements for vegans.
Also, you're confused about what the peer review process is, it's not just someone's opinion about how they feel--it's about fair treatment of experimental evidence. The answers aren't yes and no as you might hope, welcome to biology. It's about building evidence and assigning likelihoods to different hypotheses.
Also, man has not evolved different dietary needs in several generations, that's so wrong it's really hard to even respond to. What's changed is that now you can take a mulit-vitamin to fill in the nutritional deficiencies from your diet. Nobody's objecting to that, I feel there are some defensible reasons to not eat animals. But saying it's somehow better for you nutritionally or that we're evolved to only eat plants is just obvious non-sense.
lostintime said:I don't eat a fruitarian diet. Neither does DR btw. We all get B12 from somewhere ... outside of ourselves. Take your pick as to where.
Peer review .... your quote .... "It's about building evidence and assigning likelihoods to different hypotheses." that says nothing definitive , now does it ?
Yes ... man has evolved . I didn't say we all should be eating plants... or we've all evolved to .... but we can if we wish.
DR lacks and intrinsic factor for B12 ... did you miss that? . . . yet you still disparage him for taking B12 injections![]()
Rip:30 said:Look up the words likelihood and hypothesis. Obviously you don't get how science works.
You're talking belief/religion, which compared to science has not done well in the last few centuries in terms of making correct prediction as to how the world works.
durianrider said:Only Dave Zabriskie is a full time vegan.
durianrider said:Cadel, Lance, Basso, Contador, Hamilton eat vegan when they want to cut weight. You know when guys like this are doing it and dont give an f about the animals/planet that there is something in it.
M Sport said:In answer to the original question "Look at me, I am a Vegan! Can I persuade you to become one too?" my initial answer is no way, I love meat too much. My second part is I have always been too serious about sport to give up meat, I don't want my performance compromised by cutting out meat.
I don't entirely believe this. The last thing you want to do when dropping weight is cut out lean meat. They are probably just more selective about the cuts and types of meat they eat. I could see them cutting out dairy though.
