The short, easy answer would be yes, IF you have access to high-quality milk, and if you normally have no trouble digesting it.
My long answer:
The first step I took towards traditional foods was when I came across the late Dr. Brewer's website, http://www.blueribbonbaby.org/
He claimed that none of his pregnant patients who followed his diet advice ever got preeclampsia.
Well, the first thing he recommended was a quart of milk every day! Previous to this, I had been off dairy for years (you can see my other posts about the disastrous health consequences that came of a low-fat near-vegetarian, heavy soy diet), but I had also come across articles about raw milk around this time. I have to admit I was a little scared, but decided to trust the new information. I started off slowly, maybe a cup of day, and built up to the quart during the middle of the first trimester. So I drank a quart of raw milk through the rest of my pregnancy! I felt pretty great following his diet recommendations, but I think YMMV.
The reason I had stopped drinking milk originally is because it left a heavy feeling in my stomach, and made me constipated. Well, raw milk gives me none of these problems.
