I was chatting with the midwife I hope to use on my next birth and we were discussing ruptures. She said the two most important things when you are a VBAC hopeful to avoid a rupture is increasing your proteins immensely and to make sure you do NOT let your iron levels dip. She suggested that even if I don't have GD next time that I should try to follow that diet anyway because it promotes higher protein intake and also take an Iron supplement no matter what. I'm sure the combination of protein and Iron won't be great for my colon but I'd probably keep taking a probiotic to help combat that.
I just thought I'd share..... It's not something I've run across in my research before. She said a lot of midwives push these things, but dr's don't.
I just remembered the only other place I have ever heard this before. There was a live chat here on pg.org with a midwife a couple months ago. I was asking her questions and she also brought up that protein and Iron were very important to help retain strength in the scar tissue throughout pregnancy.
