What's the big deal with steel cut vs. regular, or is there?
Steel cut oats are cut pieces of the groat(the oat nut), still have the bran and aren't processed in any way. Regular oats are usually steamed, rolled and then cut/dried and don't have bran remaining. If you're avoiding processed foods, this is one to avoid. The more 'instant' the oats are, the more processed they are.
