I ordered this book in January 2020, and a new version is coming in May. I wanted something to guide me from the beginning of my pregnancy (I'm 8 weeks) so I figured the older version would do. WRONG. It was published in 2005 and so many changes have been made to nutritional guidelines and health knowledge that this thing is a dinosaur. Doesn't even have the word "avocado" or "coconut oil" in the index - foods known to be very beneficial during pregnancy.
If you can wait til May, I'm sure the updates will be great. But this edition is a no go.
