Dear Jeremy, I am a mother of two, and was a vegetarian during each of my pregnancies- Oops. I am sorry to say that due to the effects my diet had on my uterus and sacrum (and yes I can prove this), I endured a C-section with each of my children. I also suffered severe swelling, extreme fatigue, polyhydramnios, sciatica, and many more complications and such during my pregnancies. Though a longtime vegetarian, I craved buffalo meat like mad. Protein is absolutely essential during pregnancy, 80 mg daily. Conditions such as pre-eclampsia and the dreaded toxemia are attributed to protein deficiency. B-12 (available only in animal ingredients: meat, eggs, milk), folate, iron, calcium and vitamin C are others whose deficiency can cause tremendous problems for the pregnant woman, or worse, can damage the baby. Dairy products, especially those containing traces of hormones (BGH) can cause painful menstrual cramps, and possibly worsen pain with contractions. Soy is especially harmful to the fetus, and I have the child with autistic tendencies who proves that. When I eat grains, it causes problems with my joints (some people get arthritis) and if the pelvic and sacral joints are not functioning optimally, the baby will have problems getting through. While this organization does not speak of paleolithic diet, I do recommend that you check out http://www.bradleybirth.org for info. on prenatal nutritional requirements and, if you're interested, natural childbirth. Please do not confuse Bradley with Lamaze, they couldn't be more different and I personally do NOT recommend Lamaze or, worse, something wich claims to be a combination thereof. Your baby's mother should begin paying attention to her diet now if you plan to conceive in the next few months. Best wishes, Stacie http://facelink.com/stacietolen
