Hi Karen,
Here are my opinions, but remember YMMV, and others may have different experiences.

Most likely it is, but when we are initially recovering, our immune system is hypersensitive due to inflammation and it doesn't take much to trigger symptoms. IOW, early on, it may react to some foods that wouldn't bother it after we're in remission.

I do remember Gabes listing her reaction times to certain foods, but this wasn't very severe, just more like I just noticed that my symptoms are a bit improved and this was back to MC "normal".....
2) This may be normal. If you observe animals, you'll notice that many will defecate soon after standing (if they've been lying down for a while), and most will defecate soon after eating. It's a normal digestive system response in order to make room for the recent meal. On the other hand, if it appears to be an urgent event, due to an adverse reaction to the meal, such reactions that occur less than three hours after eating are almost surely caused by a histamine issue (because IgA-based reactions almost always occur three or more hours after exposure).
In my case, I appear to react to gluten (obvious symptoms,such as bloating or diarrhea) approximately 3 to six hours after exposure (ingesting it), with joint pain beginning the next day. For soy, reactions (cramps, ileus) begin about six hours after exposure. For dairy, it takes roughly 24 hours, but it may cause constipation, not diarrhea. If I eat beef, I get minor boating about six to twelve hours after exposure, and the next day I'll have a headache and upper back pain (but no diarrhea). IOW, we all seem to have our own reaction pattern, depending on how a particular food affects us. We eventually learn to recognize that pattern and that helps for interpreting future reactions.
