I have eaten the cores and all, however I read that the pips are poisonous so stopped.
Probably you need to eat hundreds for them to do any harm, however I no longer eat them.
I now have a plastic thing that cuts an apple into pieces and take out the core, so that part goes straight in the rubbish and I always eat my apples this way now rather than just biting into a whole apple.
Yes I often do. I swallow the seeds whole and have heard they are poisonous if cracked. I have also heard that there is an enzyme in the seeds that is important for health and scarce in our diets. I haven't done this with pears and now I wonder why? I think it's beacause pears are soft and the core is not.
I don't normally eat the core or the pips of apples,though when I was a kid,I would eat the entire fruit!!! I have no idea at all why,unless it was when I was out somewhere and could not find a rubbish bin! Even back then,we were very concerned about littering and the bad effect it had on the world! Mind you,apple cores would rot down and compost into the ground,so AGAIN, I don't know the reason I ever ate the silly things!! It's not as if they taste any better than the rest of the apple!!
