What cooking oils can become trans-fats if they are raised to a very high temperature?!
If you heat oil past it's smoke point it will break down but will not become a transfat.
Here is a smoke point chart.

Answers: Trans fats are made trough a process of hydrogenation, not just merely heating oil to a high temp.

OK, I'm not an expert...
I think that trans fats are made by superheating oils and processing/binding them with hydrogen (that's why they're also variously called hydrogenated or partially hydrogenated oils). Doing this increases the stability and therefore the shelf life of a product (which is why there's so much trans fats in things like cookies and so on).
Merely heating up an oil or fat does not make it a trans fat. It's true that trans fats seem particularly toxic, but really it's more a question of degrees of toxicity than one being unhealthy (trans) and the others (olive oil, etc) fine. For optimal health, it's best to stay away from ALL refined fats and oils.
Hope that's right and it helps!
You are right, most oils do change when heated. Usually over one hundred degrees C . Since learning of this I have changed to Rice Bran Oil. This oil can be heated to a very high temperature without any change. This oil is also rich in antioxidants. Lovely oil to cook with and there's no after taste.
IT is all nonsense
the food freaks would have you believe bad food is all about you... NONSENSE every food you use today has been here in the market place for thousands of year ever since civilization..
Please !!! Common Sense...
Trans Fat was coined in 1985... About 2003 the issue started
ONLY FAT people are subjects to be concerned about eating standards,....
The health industry will get the government to increase our taxes to pay for their defects...quick tax smoking to stop fat..
