Vegans who start the diet as B12 sufficient adults can go up to 20 y before showing B12 deficiency symptoms due to enteric recycling of endogenous B12. In the meantime you can develop subclinical B12 insufficiency and do damage to your nervous system without knowing what is happening. Years ago I tried vegan eating without taking B12 and it didn't serve me well at all, I believe it was one of the reasons I didn't sustain it then, so since I resumed vegan eating almost 4 years ago, I've never wanted to take that risk and have taken fortified foods and supplements the whole time.

In our opinion, vitamin B12 in supplements is "full natty" since it is all derived from microbial fermentation, which is the ONLY natural source of B12 in the world (animals don't produce B12, they all get it from microbes). All B12 in supplements and fortified foods is from cultivated microbes. If cultivating microbes for B12 is "unnatural" then all of our cultivated food is "unnatural" and except for those few remaining hunter-gatherers who eat only wild foods, none of us is fully natural regardless of whether we use B12 supplements or not. I have a blog post about this: http://donmatesz.blogspot.com/2011/12/vitamin-b12-and-human-nutritional.html

We use fortified soy milk and nutritional yeast throughout the week, and on weekends take a liquid B12 supplement we get from Sprouts Markets (house brand).

 B12 is unusually sensitive to microwave heating.  B12 can be lost from foods when juices are lost from the food, but ordinary cooking methods do not actually damage it.  In contrast, microwaves actually inactivate B12.  http://www.ncbi.nlm.nih.gov/pubmed/10554220

As for ordinary cooking, we don't have good evidence one way or the other.  Some people speculate that cooking may damage B12 and this may contribute to B12 deficiency in omnivores, but I am not aware of any evidence supporting this idea.  Cooking foods however can lead to losses of B12 if there is a loss of juices from the food during the cooking.

Here is Jack Norris's take on this:  http://jacknorrisrd.com/cooking-b12/

Not surprised this happened in Ohio, the State there is pretty heavy handed on several fronts, very tight with "professions" claiming to "protect" the public from....innovators who threaten the entrenched cronies.  Good luck!

The war on cash is a war on privacy, individuality, and freedom.  The governments want to track your every move, watch every thing you do and purchase, by making it illegal to trade in cash so that you have to use electronically trackable "money."

The claim "fruit is necessary" has no scientific basis.  A person can eat starches, beans, nuts, seeds, and greens without fruits and meet all nutrient needs without eating any fruit.  If you eat a raw foods diet, you need to meet all essential nutrient needs; it is very unlikely you will meet the minimum calcium requirement for humans (about 600 mg per day) eating only fruit.  

There is no non-human primate that lives exclusively on sweet fruits.  ALL of them eat greens in large amounts, and they also eat nuts and seeds whenever possible.  There is no evolutionary or nutritional reason to believe that humans are adapted to a 100% sweet fruit only diet.

It is totally irresponsible to promote a 100% fruit diet for the majority of the population.  No educated nutritionist would endorse this position.  Dr. Michael Greger would never endorse that position, nor would Ginny Messina R.D. nor Jack Norris R.D. at VeganHealth.org.   And definitely, most people would find it harder to stop eating ripe mangos than to stop eating steamed greens.  It absolutely is important to stop the spread of this misinformation that will get many people in trouble and only cause trouble for the vegan movement when someone gets very, very sick from following irresponsible advice spread by someone who has no science-based training in nutrition.

McDougall sites studies that shows when eating antiacids with meat increased bone mass as where eating without antiacids decreased bone mass.

According to cronometer, I have consumed 2.3g of lysine (over 100% daily value) and 1722mg of calcium from eating 2000g of watermelon (1.2g of lysine), 20 small tangerines, 15 dates, 3 cups of almond milk, and 3 tbsp of chia seeds. So you are right, one cannot just eat fruit for the complete spectrum of nutrients. You would have to include some seeds and greens if you didn't know exactly what to eat for required nutrients.

Calories aren't really relevant unless you're talking about calories from fat, but that's another discussion.

Funny skits!  But totally serious subject.  Because of the variation in humans, there may be a very small percentage of people who can survive on fruit only, just like there are a few very short people, and some very tall 7' +.  That doesn't mean that everyone can do so.  Before you start making diet recommendations to people you better make damn sure your recommendations really do meet the needs of everyone you are speaking to, BECAUSE IT IS YOUR MORAL RESPONSIBILITY TO DO SO!  There is nothing 'vegan' about shirking this responsibility.   Your own private experience for some months or even years is not enough to make you an expert on human nutritional needs.  Nor is the echo chamber of the raw food community a reliable resource for nutrition facts.  There are people who live in different conditions, there are women of childbearing age, there are pregnant women, etc. etc.  When I see videos like Carr's I feel quite angry.  This person has no evidence or logic or qualifications for making such pronouncements that will influence other poorly informed people.  It is just irresponsible.  Period. And this kind of pseudo-scientific irresponsible stuff would kill the vegan movement if it weren't for rational responders like you two and of course Dr. Greger, Campbell, etc, etc.
