That's why other people think it's weird, but you need to eat a lot of apple seeds to ingest a sufficient amount of CN for it to reach life threatening levels. I'm talking like 2-4 seeds, which isn't very much - but thanks for the warning.
I also eat the apple seeds. Be sure to chew them a bit so they don't just pass through whole. Yes they are very good cancer fighters. Just eat them when you eat the apple.
