Hi Syl, I wasn't disagreeing with the fact that the very act of eating stimulates the gastrocolic reflect, which is what the links you provided to Heather's site and Dr. Whorwell's video indicate. I experience that myself - when I eat, I feel it in my asending colon right away. I was just looking for some evidence that the SF/IF ratio affected the strength of peristalsis. Clearly, the people on this site find that it does for them, so I am not going to say that it doesn't. But it wasn't something I'd read in the literature. The link you provided to Whorwell says this:
Cramping and diarrhea
Certain foods are known to stimulate gut reactions in general. In those with IBS eating too much of these might bring about or worsen symptoms. For example symptoms of abdominal cramps and diarrhea might be brought on by...
•Meals that are too large or high in fat
•Fried foods
•Coffee
•Caffeine
•Alcohol
Again, no reference to meals high in IF. But I know that people on this site get "attacks" as soon as they eat a particular food, so I am not going to dispute that. It was just not a causative link I'd drawn in my own eating/symptoms, possibly because I almost always eat IF and SF together, as per the EFI rules.
