Hi, Skywalker:
Yes, because some people were just fated to develop AS.
There was an episode of South Park in which a rather different way (direction even) of consuming foods was discovered.
Do this with any carbohydrate and AS, in a susceptible person, will eventually emerge.
And if it were not an over abundance of flour-rich foods like pastas, it could instead be something like fried milk products that would provide the food for our nemesis bacterium.
If we were all PERFECT, we would not get AS, but even only a "little bit perfect" would do--if we could enter into adulthood with our intestinal linings intact, we would not develop AS despite extreme contamination and adulteration by starches.
Gird up Thy loins: Seek Ye then that PERFECTION which shall equip Thee against this EVIL.
HEALTH,
John
