I hear this "cheap oil" thing a lot in food pseudo-science Internet writing. What exactly is "cheap oil"? And, is there any peer reviewed evidence for your claims about how you feel after eating "cheap oil"? If this effect is so drastic, then, surely, it must affect others, and would be an interesting and worthy research topic.

I guess it's generic vegetable oil as opposed to Canola oil or Peanut oil? I'd actually suspect that a mindset of buy whatever oil is cheapest from Sysco would pursue cheapness in other areas as well including kitchen supervision/skills.

I wouldn’t suspect that at all—some recipes (like certain kinds of “street food” from different countries actually call for the use of cheaper oils :)

I doubt it makes any appreciable difference anyway most of the time although Canola oil and Peanut oil do have a slightly higher smoke point than vegetable oil.
