From my experience, much of this comes down to the design of the system: was some state modified prior to an error occurring? If so, can it easily be rolled back? If not, why not?
The worst "attack" I've ever had was with spaghetti squash. I got the usual: bloating and diarrhea but on a scale I had never experienced before. I felt extremely tired void of any appetite for a couple days after. Really wonder what in it did it for me. Maybe it was a coincidence, or an allergy. Haven't figured it out to this day. Other than that, any enriched flour pretty consistently gives me light bloating.
Unrelated but I found this paragraph in the article quite... weird. Natural juices and vitamins?
>One woman, Sandy Funk, had begun having blackouts at the age of 37, having developed a brain tumor. She got herself onto a diet of natural juices and vitamins, and was able to live for another 18 years, but only after they had removed two thirds of her tumor via a surgery.
This is where static checking comes in. Static tests should fail if it's assumed (and not asserted) that a key exists.
