Hi Mike,
It's been 2 years since my put down and like you, two months after my third surgery, I also experienced the great feeling of eating everything I love (including pizza, burgers, French fries, beans, etc., that I wasn't able to eat in about 3 years of a bad UC flare up). That wonderful "period of grace", last about six months. After that I was hospitalized for esophagitis and an obstruction on my J Pouch caused by liquid iron supplements that almost killed me. Since then, I developed lactose intolerance, but after a couple of months, I was able to eat pretty liberally again. My problem is that I love to eat (thank God my dad's genes made me tall and I can put some extra pounds with no big deal.
For the last year and most of 2016, I been dealing with a lot of Pouchitis episodes caused mainly by my excess on my eating habits. Right now I'm recovering after an aggressive Pouchitis that didn't stop with antibiotics. At this point I decided to eat with discipline and responsibility and noticed that reducing my carbs intake daily, is improving my health a lot. I'm trying right now to eat smaller meals and snacks (5 times a day), incorporating more fruits (apples, papayas) and proteins on my diet (grilled chicken, lean pork) and a not more than two dairy products per day (lactose free). I haven't introduce vegetables and green salads yet (which I love) I'm still recovering from an awful and aggressive case of Pouchitis, but that will be my next step. I also recommend to drink as much fluids as you can, two liters is the minimum, the more, the better and I'm taking Beano enzymes (can find then in any pharmacy) to the ease your digestion.
I think the key word is control. Be aware of what we eat, instead of the idea of a special plan or diet that could work for me, but not necessarily for you. I downloaded an application on my iPad called Numbers, to keep track of what I eat to know exactly what is good or not for me.
I hope my experience call help you some. Good luck!
