The thing is, there have been healthy, thriving vegetarians and vegans for as long as there have been humans. Some were so do to moral or ethical concerns, others due resource utilization issues, others due to cultural taboos. All other factors being equal, the veg(etari)ans have thrived, and continue to do so.

For some more recent historical examples of vegans, we can look at Pythagoras, the “Pythagoreans” (as vegans were called for the following 1300 years). Buddhists, Jainists, et al., have been doing grand as veg(etari)ans since around the 6th century BCE. There are many more examples, but the point is as it effect this conversation is that vegans have not and do not suffer greater occurrences of edge case conditions such as depicted in this article any more than the rest of the population, and it’s just silly to suggest otherwise.

But then, this story is sourced from Fox “News”, so I suppose we shouldn’t expect much in the way of academic or scientific rigor in the reporting, eh?
