As a more-or-less normal human being who has evolved to eat meat a well as vegetables, let me recommend the following book for a more balanced view of this issue.

Catching Fire: How Cooking Made Us Human by Richard Wrangham

With care and modern technology, a person can survive or thrive on a strictly vegetarian diet, but the doctor's approval is not the same as an endorsement.

And, as that book notes, going to the extreme of eating only raw food could be a threat to a woman's reproductive health, which suggests it is also a threat to her pregnancy.
