Welcome to the team and to SP! There is information in our team, so click around and see what we've shared. Learning how to figure out YOUR GP diet is very important, and I've posted about that several times. If you need more explaination, please let us know. There are several team members who have been living with GP for awhile and understand it pretty well. I was diagnosed 2 years ago and since I have a background in human biology I've spent many hours (I'm guessing around 300) studing how the digestive system should work and what goes wrong with GP. It's a lot of information but it helped me understand more what was happening and what I can do to make this easier.
As for meat, avoid fibrous meats. Chicken and fish tend to work much better than steak or pork chops. Also avoid high fiber foods - raw veggies (especially fibrous veggies like celery) and whole grain foods contain high fiber. Avoid high fat foods too. Fat and fiber are the 2 hardest to digest macronutrients. Foods with seeds, kernels (like corn), and fibrous pieces (like steak) leave behind indigestable pieces that can sit in your digestive tract for awhile and cause problems.
Feel free to ask any questions you have. If we can't answer them we'll help direct you to where you can find an answer.
