For example, I've noticed that green apples survive much longer over strawberries and oranges, even when they are all kept chilled for the same duration of time.
I once read that apple pips contain cyanide. Is this substantial enough to be harmful to humans who choose to eat all of the apple, including the core? If it's not a high content, then how many pips would you have to eat to feel the effects?
Similarly, do other fruits also contain harmful amounts? Stones from peaches and plums are much bigger than the pips in an apple...
