Wow, that's not true at all. Maybe you
should read the articles.
I am a "strict" vegan and know many vegans,
and none have the problems you describe. My step mom recently went
vegan and has been really excited about how much more energetic she
feels.
On the other hand, the USDA has done surveys that suggest the
majority of people have at least mild nutritional deficiencies. So
those eating the typical 'western diet' of meat, dairy, and refined 'white'
carbs are the ones that should be worried. Also, quickly googling
'western diet disease' brings up lost of info on all the chronic, common
diseases (heart disease, cancers, osteoporosis, diabetes) that the American
diet has caused to massively increase... whereas googling 'vegan diet
disease' shows results about
chronic disease prevention.
I'd agree that vegans should take a B12 (or
better yet, multivitamin) supplement, but so should meat eaters. All
the other nutrients you mentioned are far more plentiful in a veg
diet.
Also, there aren't really several versions of vegan,
but there are many types of vegetarians (lacto-, ovo-, and you, know, the
people that are ""vegetarian"" but eat fish, etc.)
And
here's a list of top notch veg athletes: http://www.veganathlete.com/vegan_vegetarian_athletes.phpBrendan
Brazier also just set up a new website all about the vegan diet that helped
him become a 2x ultramarathon champion:

I tried to keep it short but I can't help but respond to someone spreading
anti-veg myths...
Take
care,
