Capetonian,
I've been trying to really keep grains and processed sugar to a minimum. Similar to the paleo diet but not fully. I find my pouch works best with a diet of lots of meat, eggs, nuts, avocados, veggies and fruits. For breakfast I just eat a banana. Lunch and dinner can consist of either salad with spinach, avocado, turkey/chicken, tomatoes, pecans, dried cranberries; scrambled eggs with some ham or turkey added, salsa, spinach and an avocado; some kind of chicken breast baked or grilled with veggies; steak and veggies; etc. There are many options and combinations you can do. I'll also drink smoothies that consist of almond milk, spinach, blueberries, peanut butter, or some other frozen berries. I find when I succeed at limiting or eliminating grains and processed sugar I feel significantly better overall and my pouch functions the best.
