The whole food part of it is extremely confusing. Reading medical research papers on the subject, even more so.
There just seems to be so much conflicting information out there.
So far everything I’ve read has been pointing in the direction of a complex hormonal (part of this could be directly related to our own thoughts), immune, and digestive interaction. There are still many aspects that remain unclear. Will update as I have a more concrete hypothesis.
As far as the apple okay today and not okay another day.
This may have been any of the following:
- food combination was not appropriate (eating fruit after a slow digesting meal increases chance of fermentation in the digestive tract)
- the flare could have been a result of something else (the apple may be simple reasoning your mind used to explain what occurred)
Not much of an answer, but the issues is so complex that having a clear cut answer is very difficult.
Consider sharing a bit about your own story in the community section. The more information that can be accumulated, the more value it may potentially hold.
All the best.
