It's actually not quite as easy, you do have to at least get a rough understanding of what you need and where to get it.

Especially for women, iron deficiency is a real problem. For some reason, they lose a bunch of iron every month and that needs to be replaced. A lot of women are running low on iron even with "conventional" diets, so dumping all the iron rich animal products can be a problem.

It's far from impossible, but you have to educate yourself a bit about your needs.
