I've just searched for "chia seeds" and found this post as I was wondering the same thing. I have also tried crushing them and testing them and couldn't see any reaction to the iodine. They look like freaky frog's eggs when they go into liquid! But I've been enjoying them with yoghurt lately, they add a nice crunch a bit like cereal with yoghurt
