Yes, the portions and frequency of such food play a huge role here. Unfortunately, this is one of those issues that is subjective to each individual. What works for me may not work for you, all that jazz.
I've suffered with chronic pancreatitis for several years and still learning the to do's, the do nots, portions and how often I can consume certain foods without having a pancreatic attack. When I have one nowadays it's an automatic 4-5 day hospital admission with no food or beverages until the last day. Just TPN being steadily fed through a pic line IV. Talk about a setback if mid cycle...
I can basically eat anything I want as long I know how much to eat in one sitting and what to have with it. It's been a long learning process. Avocados are part of my regular diet but I have to mix half or maybe a whole one with things like rice, spinach, chicken and cottage cheese.
I have to do the same with tomatoes, potatoes, nuts and dairy. For example I can't eat 6 eggs with just tomatoes & shredded cheese. But I can eat them with spinach, cottage cheese, a meat product. No matter how many docs & professionals I've spoken with, it always comes back to solely me - it can't generally be compared to what works for others because to put it most basic, two different digestive systems are rarely alike.
I can eat natural PB all day & be fine. Bob next door ends up in the fetal position after eating the same.
This is my experience anyway. I wish you luck & would greatly appreciate if you share any tips & tricks you may come across.
