A new article has come out, entitled "Is eating vegan while pregnant as bad ask smoking, drinking?" The title alone is enough to make anyone angry, and many did. It is inaccurate, unproven, and just poor journalism. This should not be allowed to be printed or posted.
The author, Chad Skelton, cited a study linking a deficiency in B12 in pregnant women to birth defects in their babies. Skelton made a noticeable error when he assumed all vegans are B12 deficient, thus are negligent parents like a smoker or alcoholic. Many vegans responded in anger to his inaccuracy.
A search on WikiAnswers revealed that meat and dairy don't contain B12 naturally. "Vitamin B12 is a microbe -- a bacteria -- which is produced by microorganisms." Soy milk with added B12 or a B12 supplement is no different than cultured yogurt, milk, or meat. Therefore, meat and dairy are not necessary to obtain B12. To say a vegan gets less B12 is inaccurate.
I posted an article recently that claimed the opposite. Careful planning is important with any diet when pregnant and being vegan does not change that.
