Is trans fat forming due to deep fry and using the same oil for frying again. Is it the bad cholostrol ?

Liquid vegetable oil is infused with hydrogen and becomes a solid known as Partially Hydrogenated Vegetable Oil. It has the consistency of Margarine or Shortening which are other names for trans fat. This process changes the chemical composition of the oil making it a free radical or oxidant (not good). Trans fat raises your LDL (bad) cholesterol, clogs arteries and prevents absorption of any good fats that might be consumed with it. It is a slow metabolic poison. It was invented in the late 1800's but never used until World War 2 when it became a substitute in the U.S. for the butter that was sent overseas to feed the troops. If you will notice that's when Stroke & Heart Attack rates began to rise. Before W.W. 2, Strokes & Heart Attacks were an 'Old Man's' disease, but not anymore. Avoid it as much as you can.

Trans-fats are (I forget the technical term) but, I can answer your question.
They have been around since margerine; when a trans-fat is heated, thus the problem w/fries, etc. (I believe they are any vegetable oil except for mono-. . . oils like olive oil) but when heated become a regular fat. Thus, the danger for cholesterol. And, the heart.
Plus, fast food places etc., sometimes don't change their oil often enough, a little vitamin E helps them from becoming rancid.
But, . . . . what restaurant would invest in that.
Lancet may have some articles; but, even butter in moderation is better than margerine. For frying, ask at your local health food store; plus, they can explain all the different oils better.
Olive oil doesn't go rancid as quickly as other oils but is not good for deep frying.
Any heating of a trans-fat will change the molecules and make it a regular fat !!!

No, actually it is an old problem that we have been having in especially junk and fast foods. Trans fats are formed when you heat partially hydrogenated and hydrogenated cooking oils and lard to cook. The fast food used it because it is cheap. The FDA had made the junk food and fast food industries stop using these hydrogenated and partially hydrogenated oils and lard to make the things we eat. Meat when cooked, also has trans fats, and that is why we should limit our red meat intake.

Trans fat is partially hydrogenated fat. This means that they add hydrogens to saturate the fat. It is found in a lot of processed and snack foods like cookies, crackers, pastries, chips, and so on. Starting January 2006 it is mandatory for trans fat to be listed on all food packages. Try to stay away from foods with any trans fat. It is said to be worse than saturated fat for you and yes it is known to be bad for your arteries.

Trans fat is basically man-made fat that should be avoided. It's not a new problem but many people are more aware of it starting last and this year.
