QUOTE: "...the trace amounts of arsenic poison the parasites but aren't enough to harm the person."
The kernel inside the peach pit contains a form of cyanide.
Other fruits containing this type of cyanide in their pits are apricots,
cherries, nectarines, plums and even apple seeds.
Peach pits contain a number of chemicals called “cyanogenetic glycosides”. These are not cyanide, but when processed in the human digestive system, cyanide is one of the resulting by-products.
One of these cyanogenetic glycosides is amygdalin, which is the same chemical that was once sold as a fraudulent cancer “cure”, under the names “laetrile” and “vitamin B-17”. The only way in which this substance was ever actually shown to have prevented anyone from dying of cancer was to cause them to die first from cyanide poisoning.
If you are juicing or cooking fruit it's best to remove the seed
pockets from apples and the pits of other fruits beforehand.
The body defends itself naturally against small amounts
of cyanide but better to be safe than sorry.
