If I remembered right, the popcorn has something called diacetyl (SP?) that are found in microwave butter-popcorn. This caused the "popcorn lungs."
From what I know, eating eggs and oatmeals everyday will not do the body harm. I haven't heard of a case where something like that happened. If you feel you must, read the ingredients and do research on each of the ingredients. Let it be known though, that anything in excess is bad for you. This dude ate bags of popcorn twice daily. Something that I hope you don’t do with oatmeal and eggs. I think if you just keep moderation in mind with your eggs and oatmeal, you should be fine.
