Another thing that may give my wife problems with vegetable oil is the cheap American cheese that restaurants use on cheeseburgers. When we eat at Braums we really like their hamburger. I will get a triple cheeseburger with bacon and she will get a double with bacon. No bun of course and no sauce. But the cheap American cheese is probably about only half cheese and the other half soybean oil and other ingredients. Add to that the burgers are probably cooked with soybean oil on the grill. So if it is the soybean oil that gives her the problem then she gets a double dose.

At home we never eat cheap cheese or anything like Velveta. We always buy 100% cheese cheese instead of the processed cheese like stuff.

She is convinced the soybean oil is the problem for her. I do not seem to have as much problem with it.
