BTW,Trans-Fat不应该翻成“反式”脂肪，应该是“转化”脂肪或者“氢化”脂肪。

正完全氢化的脂肪是没有trans fat的，只是有些部分氢化的才有。这里是wiki的解释：
Trans fat is the common name for unsaturated fat with trans-isomer (E-isomer
) fatty acid(s). Because the term refers to the configuration of a double
carbon-carbon bond, trans fats may be monounsaturated or polyunsaturated but
never saturated.
Unsaturated fat is a fat molecule containing one or more double bonds
between the carbon atoms. Since the carbons are double-bonded to each other,
there are fewer bonds connected to hydrogen, so there are fewer hydrogen
atoms, hence "unsaturated". Cis and trans are terms that refer to the
arrangement of chains of carbon atoms across the double bond. In the cis
arrangement, the chains are on the same side of the double bond, resulting
in a kink. In the trans arrangement, the chains are on opposite sides of the
double bond, and the chain is straight.
The process of hydrogenation adds hydrogen atoms to cis-unsaturated fats,
eliminating double bonds and making them into partially or completely
saturated fats. However, partial hydrogenation, if it is chemical rather
than enzymatic, converts a part of cis-isomers into trans-unsaturated fats
instead of hydrogenating them completely. Trans fats also occur naturally to
a limited extent: Vaccenyl and conjugated linoleyl (CLA) containing trans
fats occur naturally in trace amounts in meat and dairy products from
ruminants, although the latter also constitutes a cis fat.
No trans fats are essential fatty acids; indeed, the consumption of trans
fats increases the risk of coronary heart disease[1][2] by raising levels of
"bad" LDL cholesterol and lowering levels of "good" HDL cholesterol.[3]
Health authorities worldwide recommend that consumption of trans fat be
reduced to trace amounts. Trans fats from partially hydrogenated oils are
more harmful than naturally occurring oils.
