Dangers of eating apple seeds and apple cores?

   Dear sci.med and other readers,
      I have heard it said that apple seed contain a poisonous
substance, such as (?) cyanide,  and are thus poisonous to eat.
Of course, the rest of the apple is fine.

Which poison, if any, is in apple seeds,  and how much is there of it?
How much would one need to eat over what period of time before this
became a danger?

Please direct responses to me, d…@cs.monash.edu.au ,  rather than to
the newsgroups.

I can send a collated list of responses to individuals or to the
newsgroups.

    Well, I think you got the right answer all by yourself: cyanide. However
    the amount is very small and nothing to worry about. I read recently
    that you’d have to eat, like, 100 apples a day (or something) to
    experience any harm. Same with apricot pits, etc. Conclusion:
    fruits and vegetables are still good for you! :)

    And all those monkeys/apes at the zoo chow down a lot of seeds during
    their lifetime … as I have for 20-some years now … still kicking and
    showing no signs of being poisoned.

    I believe it is cyanide. But the amounts are pretty small. I think the
    LD50 for KCN is 8 mg/kg. But, it’s been a long time since I looked up
    that figure. Anyone have a toxicology source?

    I think someone got their fruit confused, I believe that the incident
    that got this whole thread started was the one involving Laetrile.  This
    was a failed attempt at a new anti-cancer drug.  Laetrile was also
    referred to as vitamin B-17 or amygdalin.  It is found in APRICOT pits.  
    The premise for it’s use was that it could be broken down by beta
    glucosidase releasing cyanide in the process.  This enzyme was (is ?)
    present in greater quantities in tumor cells than in normal tissues so it
    should preferentially destroy tumors.  It proved to be ineffective in
    practice.  I have heard that there are recorded cases (usually involving
    children) where poisoning has resulted from ingestion of apricot pits.  
    I’m not sure whether or not the same compound is found in apple seeds
    (although it wouldn’t be surprising) but I imagine it would be present in
    much lower amounts if it’s there at all.

    David, don’t worry about the seeds and core.  Your concern should be for
    the pesticides which are on the surface of the apple, and in many cases
    the fungicide trapped under the wax coating.


    O for that moment to be now

     i think an important thing to keep in mind here is whether you are
    swallowing the seeds whole or actually chewing them (they are very bitter
    inside).  if you are swallowing the seeds whole, you have no worries – the
    seed coating is such that it will pass through your digestive tract
    intact. (this is according to my biology prof and i tend to believe him)  
    and even if you are chewing the seed, i think it would take an
    awful lot of seeds to reach a level of cyanide that would be harmful to
    you.  (you’d probably have to eat -just- apple seeds all day).

    She speaks the truth; They do contain cyanide but it would take a lot to
    get you sick.
    As for cores;  No problem as far as I know.  They contain pectin and I
    eat them.

    I recently ran across an insert in a mailer from Dr. Julian Whitaker’s
    Health & Healing.  A person once died after eating (PLEASE NOTE) a pound
    of apple seeds.  Let’s get real,  someone has to be pretty desparate to
    eat not one seed but a pound of seeds!  I also found apricot nuts in a nut
    shop.  These also seem to possess a high concentration of a cyanide
    (alkaloid [?]), based on the taste.  I would not recommend them for anyone
    unless they were somewhat sadistic…

    Be Well,

    I’m very interested with your "offer"
