Dangers of Vegetarianism?

Not espousing one diet over another, but....

I have a friend who was an ovo/lacto/pesco vegetarian. Carefully ate organics, "free range" and the like. She still got breast cancer.
You can be as careful about your diet as you like, but sometimes there's no escaping genetics.

Vegetarian doesn't necessarily equal "healthful." French fries and Fritos are vegetarian -- doesn't make them healthful.

Humans throughout history have been omnivores. If you can make the effort, and eat a varied, healthful diet that eliminates animal products, more power to you.
