I'd like to add two more points.
1. A contributing factor of the danger without doors man eating them is the
lack of stomach liquid (water) at the time of eating, aiding the astringency to
bind the mass thus helping form a bezoar. In Lee Reich's book, "Uncommon
Fruits Worthy of Attention," he writes of the chemical compound leucodelphinidin
in astringent persimmons. This compound tends to bond proteins and well as
absorb moisture, therefore the harsh choking experience when biting into a very
astringent persimmon. This same bonding and absorbing of moisture is a factor to
forming bezoars. If one is eating a quaintly of whole persimmons don't eat
the seeds, avoid eating the skin especially from the calyx area which usually
carries a higher degree of astringency and if possible drink plenty of water.
Best just to eat juicy very ripe persimmons.
2. Defending our friend Dr. Parmar, who states, "No, not true at all. I eat
a lot of persimmons every season. I do not peel the fruits nor I have seen
these being peeled by anyone even in Japan." I believe the danger is much less
if eating D. kaki, especially the non-astringent varieties which is the
primary persimmon species in India. Chiranjit, please correct me if I'm wrong.
PS. I know of no actual cases of persimmon bezoars, first hand. I don't
consider it a grave danger, but if one forms there is only one cure, surgery.
