The seeds of apples, pears, peaches, apricots, mangoes, etc. have amygdalin which converts into hydrogen cyanide in the body. If I am not mistaken, almonds have this in small amounts too, though only bitter almond has it in concentrations enough to pay attention to. While a small amount is fine (say the seeds from one apple per day), too much of it can cause health problems.
