I think this book offers a good approach for people who find themselves at odds with pregnancy limitations. Being scientifically minded, I was already reading NIH studies before I knew this book existed and I wanted to check it out to see if there was anything I was missing in my approach.
My primary concern was my fish intake, but the findings in this book were consistent with the suggested revised recommendations by the former head of the FDA's seafood division. So I'm good.
I read the alcohol section even though I had already decided that I wasn't going to drink while pregnant. One thing to consider is how the studies she uses are applicable to you as an individual. I get the Asian glow that's indicative of an inactive aldehyde dehydrogenase enzyme which would allow more of the toxic part alcohol breakdown to stay in my body. Studies based on European populations aren't going to be as helpful to me.
One thing that bothered me was that the bottom lines were phrased rather conclusively when I felt it should've been more like "the data suggests that in this population..." Other than that, I'm glad I'm not the only one that felt this way about pregnancy guidelines.
