Trans Fat

Trans Fat is the common name for a type of unsaturated fat with trans-isomer fatty acids. Trans fats can be monounsaturated or polyunsaturated.

Most trans fats consumed today are industrially created by partially hydrogenating plants oils - a process developed in the early 1900s and first commercialized as Crisco in 1911. The goal of partial hydrogenated is to add hydrogen atoms to unsaturated fats, making them more saturated. These more saturated fats have higher melting point, which makes them attractive for baking and extends their shelf-life. Another particular class of trans fats, vaccenicacid, occurs naturally in trace amounts in meat and dairy products from ruminants.

Unlike other dietary fats, trans fats are neither essential nor salubrious and, in fact, the consumption of trans fats increases one's risk of coronary heart disease by raising levels of "bad" LDL cholesterol and lowering levels of "good" HDL cholesterol. Health authorities worldwide recommend that consumption of trans fat be reduced to trace amounts. Trans fats from partially hydrogenated oils are more deleterious than naturally occurring oils.

Chemically, trans fats are made of the same building blocks as non-trans fats, but have a different arrangement. In trans fatty acid molecules, the hydrogen atoms bonded to paira of doubly bonded carbon atoms (characteristics of all unsaturated fats) are in the trans rather than the cis arrangement. This result in a straight, rather than kinked, shape for the carbon chain, more like straight chain of a fully saturated fat.

From Wikipedia

And why are using this stuff? Because they are cheaper than non-hydrogenated oil. But why are they banning all these herbal medicine out there and they can't ban something that has nothing good to bring in our body?

They are very concern about the health/obesity in this country. But they are the source of it all. Right now, I only use vegetable and corn oil for deep frying. And I make sure I don't heat it up past 350 degrees F. I use virgin coconut and olive oil with everything else. Take care of your health.

"I'm a Research Associate in the field of Child Development and Human Relations. I have a continuing program of research (What mother doesn't?) in the laboratory and in the field (normally I would have said indoors and out). I'm working for my Masters, (the whole darned family) and already have five credits (four sons & one daughter, 1 joined the working community, 4 are being educated @ home ). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it). But the job is more challenging than most run-of-the-mill careers, and the rewards are more of a satisfaction than just money."
