Topic: Astringency in certain fruits & vegetables; stomach & GI tract bezoars.

Aside from celery, coconut, pumpkin, leeks, beets, raisins, citrus, I would think under-rip bananas, and, of course, under-ripe persimmons, does any one know if any of the following fruits can also, in large and frequent quantities, result in bezoars is humans and live-stock:

*Autumn olive; goumi; Russian olive; silverberry; etc.

*American plum and other tart-skinned plums

*wild grapes, like northern foxgrape

I sometimes over-do the Autumn olives on hikes – my stomach feels the same as when I consume under-ripe persimmons; I think that they have a high ratio of indigestible cellulose and tannic acid.

Thanks,
