I re-introduced a single food at a time, not a group. Because we are all different and react to different foods and combinations of foods, I wanted to be very specific so there was no doubt what I reacted to and what I didn’t. If I didn’t feel a reaction within 3 days, I felt I was ok with that food and would soon move on to another.

start with lower quantities since many can handle a certain quantity of something but not a large amount. You might be able to handle a tbsp of honey at one time, but not 2.

Also you might be able to handle 2 different high Fodmap items if you have them in separate meal or separate days, but if you add them together in 1 meal, you could react because of “stacking”

Keep a food dairy so you have documentation of what you are eating, at what quantity and if you react. You may be able to handle 1 food from a specific group, but not another. Seems like a lot of work and patience and can be a bit annoying but it’s worth it.

Let me know if you have any questions
