I tried this low-starch diet for my Ulcerative Colitis but it didn't quite do enough to fix my horrible symptoms. Low-starch is just the beginning for me. I also found, by keeping a food journal and paying incredibly close attention to my gut, that other foods needed to be removed as well.
My "bad" list: grains (all kinds not just glutens), most dairy, all sugars including most fruits and juices, all starchy foods including potatoes, winter squash.
What has reduced my UC symptoms 90%=high protein meat/fish/nuts (no soy), lots of non-starchy veggies and low sugar.
Sounds a lot like the Paleo Diet but I came by mine the hard way, kind of what Carol the author did, by finding the foods my gut liked vs. hated.
UC and related diseases like Crohn's and AS seem to be very individual and the food that works for me may not work for the next girl/guy.
Thank God for almond flour and honey so I can make yummy desserts, that's my gut and yours may be different.
I salute Carol for her book but suggest to people who try it and don't quite get their cure to keep tinkering with your diet, listen really hard to YOUR gut, keep a food journal and you WILL find your own personal cure. Doctors and drug companies will not help you do this, there's no money in it. They want a lifelong customer who comes back month after month year after year.
Discover your own cure, no one else is going to do it.
The book I recommend: Life Without Bread-no recipes but a scientific explanation why carbohydrate are bad for our bodies
