UPDATE
Before I start, I'd like to thank everyone for the support, advice, and general love that you've thrown our way. I really appreciate it and it's helped me feel confident that I'm not as crazy as the dietitian thinks I am.
After talking to my wife yesterday evening, I was livid. The nutritionist (a different one that the one we initially saw, I think it was her assistant?) came in and lectured my wife for OVER AN HOUR about how she was harming the babies if she deviated even a single point from their macronutrient profile. She also contradicted herself numerous times, told her that moderate salt intake was fine "our guidelines do not limit sodium intake, so don't worry about it", and continually hounded her even after she left the exam room (and she did all of this while my wife was getting an ultrasound, so she didn't get to pay attention or ask any questions about that).
The lady told my wife to not research diet, 'because you can find evidence to support anything on the internet', and to instead just trust the experts. She used an her mother's cancer diagnosis as an example citing that she just trusted the doctors and now her mom is cancer free. Well my wife's mother had cancer, and if my wife hadn't done her own research and been so damn stubborn/insistent about things her mom would be dead now (because the doctor failed to even test/biopsy the ever growing lump in 3 consecutive visits.)
My wife left in tears, with badly swollen legs (she sat on the exam table for over an hour), and last night at 9:30 pm (6 hours after getting home) her blood pressure was 145/90, which is about the highest its been since leaving the hospital (I'm afraid to guess what it was while in the office).
I am scheduling an appointment to meet with the doctor who operates the practice later today. In person, not by phone, so I can express my concerns and make him aware of what happened.
That aside, I've decided that we are off the 'diet' and I've put my wife back onto whole--real-- foods, plenty of fats, and low/moderate carbs (from healthy sources). After dinner last night her blood sugar was 97. Every time she has broken with their advice her blood sugar has been below 100. In fact, the only readings she has that are over 100 (a 140 and a 115) are after strictly following the 'recommended' breakfast model. (Insert my shockedface.jpd)
I am going to clear with the doctor to move her to a different diet. We will continue to monitor her glucose levels and blood pressure, knowing that her blood/urine are checked at least once a week and that the babies' sizes will be checked every other week, and should things got out of hand we'll consult a different nutritionist.
The diet will be built around a macro profile of 20:30:50 (C:P:F), per http://diabetes.diabetesjournals.org/content/53/9/2375.full, and food selection will be a combination of paleo and the guidelines found at http://www.blueribbonbaby.org/ifyouarepregnant/daily-pregnancy-nutrition-checklist/ and http://www.blueribbonbaby.org/ifyouarepregnant/what-is-a-good-nutritious-balanced-diet/
(She has no celiac, lactose, or casein issues, so I'm OKing cheerios/oatmeal in the morning, because she likes them and her glucose levels don't get all crazy). The above will, of course, serve only as a guide line. If she is full she doesn't have to eat everything, if she hungry she can eat more. Fruit (limited) and fatty (whole food) snacks will be available to her (versus packaged processed garbage). We will, however, continue with the meal spacing (3 meals, 3 snacks, 2-3 hours apart) as my wife felt it would make glucose monitoring easier.
Does this meal plan look fine?
