Offal was a regular part of our diet when I was growing up since it was cheaper than regular meat, and I actually loved liver and onions, and kidneys, before I became vegetarian. Like Phred, I grew up in an era when you got a clip round the ear, at least, if you didn't eat the majority of what was on your plate. However, after several heave-ups at the table whenever my step-mother used pearl barley (another cheap but nutritious food), she stopped trying. I feel my gorge rising just writing the name of that food down, can't even look at it in the grocery store. I loathed swede (rutabaga) and marrow (a stringy and watery very large squash) also but they didn't make me sick.
