There seems to be quite a bit of information around relating to gestational diabetes diets, but really it bears no difference to any other food regime. As with any diet, a gestational diabetes diet must cater to your personal. A number of pregnant ladies have raised sugar levels from just eating sugary foods, meanwhile others are affected by fruit sugars and others by carbohydrates or low releasing sugars.
During my first and third pregnancies I had to deal with gestational diabetes, but with each of those 2 pregnancies I suffered differently. With my first pregnancy it was only pure sugar that affected me, so I just eliminated it from my meals completely for the rest of my pregnancy and had no more problems. With my third pregnancy pure sugar didn't seem to affect me at all, but slow releasing sugars did.
Cutting slow releasing sugars out of your diet completely is hard enough, but this in conjunction with a pregnancy can cause excessive fatigue. Being that this was my 3rd pregnancy, I had two boys at the time aged 2 years old and three, so I needed all the energy I could get. I read a a mass of information in pregnancy books, but could not seem to find the information I was looking for regarding my specific gestational diabetes diet needs.
I spoke to my diabetes specialist, and she advised me to test out low carbohydrate alternatives, even if this raised my glucose levels for a couple of meals, it would be better in the long run. So I started testing and found a a vegetable spaghetti and brown rice kept me well within the correct glucose blood level. I eliminated all the other carbohydrates from my meals and there I had it a personal gestational diabetes diet.
In my experience, the answer is without a doubt, gestational diabetes diets do work, but you should ensure that they cater to your needs.
