The author of the article isn't a nutritionist or doctor, and says many things that contradict mainstream dietetic orgs. They say it's okay to have a well-planned vegan diet:"Well-planned vegan and other types of vegetarian diets are appropriate for all stages of the life cycle, including during pregnancy, lactation, infancy, childhood and adolescence."from:http://www.eatright.org/cps/rde/xchg/ada/hs.xsl/advocacy_933_ENU_HTML.htmI try to eat mostly vegan, and although I understand it sounds extreme, I think there is a lot of unnecessary suffering and killing in the egg and dairy industries. I've even heard people involved in animal agriculture say that the egg industry is the worst of them all. So I think for people that give up eating meat for ethical reasons, it makes sense to also give up eggs and dairy. Here's a typical egg facility:http://www.mercyforanimals.org/ohiofresheggs/video_gallery.asp
Jeff: Thanks for your comment, and for the links. It's good to get a perspective from a vegan on this, but it doesn't change my mind. I once ate a whole dinner that a vegan would approve, but I was just as hungry afterwards as if I'd eaten nothing.
If the reason some people are vegan to prevent animal cruelty, I think eating organic, cage free, free range eggs, chicken etc can be considered as a viable alternative. Granted it will be costly than factory farm products, but a) cruetly is avoided except of course they die, but then death is bound to happen in the natural world anyway b) antibiotics and other chemicals and unhygienically grown animal products are avoided.
