Your OB will be the best person to ask regarding pregnancy and fetal nutrition wellness, as she has your records including your test results (like glucose test). She can give you the list of foods to avoid as well as those that you need to eat more during this period.
My birth doula (https://www.facebook.com/velvetbirth/) also gave me some food and juice recommendations, as well as different exercises as I was aiming for normal spontaneous delivery.
