Not trying to start a fight but.... Yes most stone and pome fruits have cyanide in the seeds, but I have yet to see any actual numbers. I don't believe any studies have been done on levels of cyanide, plus lots of people swallow pits/seeds without getting sick. Hell the common poinsettia was thought to be highly poisonous until a few years ago. I am more afraid of salt, seriously check the lethal dosage it's crazy low, lower then most chemical used on a golf course.
