The Structure of Fats
The principal portion of a fat molecule consists of carbon atoms chained together with hydrogen atoms attached to their sides. When all of the carbon atoms have hydrogen atoms attached to either side, they form a saturated fat. If a hydrogen atom is lost, the fat is monounsaturated, and fats with multiple hydrogen atoms missing are called polyunsaturated.
This by itself is not too important, but whenever a hydrogen atom is missing (unsaturated), there’ll be a double bond between the carbon atoms instead of the typical single bond. You may be wondering why this is important, but knowing the double bonds is the key to understanding hydrogenated fats and fats.

Also, any additional saturated not needed for energy will be stored as fat. There is, however, one benefit to saturated fats: they are very durable and are highly resistant to physical alterations.
Hydrogenation is a manufacturing process used to alter unsaturated fats, generally to increase the shelf life of packaged products. This shift is accomplished by altering unsaturated fats in the point of their double bond(s). Unsаturаtеd оіls саn bе соmрlеtеlу hуdrоgеnаtеd оr раrtіаllу hуdrоgеnаtеd, аnd еvеrу рrосеss аffесts fаts dіffеrеntlу.

Unfortunately, there are also some additional unnatural compounds created during the process that aren’t found in natural saturated fats. Following this process, the fat will have almost an indefinite shelf life, although it loses all any health benefits linked to the original fat.

This means the fat does not wind up resembling a saturated fat and you will find even more unnatural compounds produced in this process than full hydrogenation. Moreover, permanent damage is done to the double bonds which change their properties from healthy to unhealthy.
Bear with me for just a little bit more science, because this is what the previous information has been leading up to. When double bonds are in their occurring natural state, they’re in a “cis” configuration. You don’t need to consider this, but you do need to know that during hydrogenation the “cis” configuration gets altered into a “trans” configuration. To put it differently, hydrogenation turns healthy unsaturated fats into unhealthy trans-fats.

The Problem With Trans Fats
I hope you are feeling somewhat comfortable with the science behind carbs, as it helps explain why trans-fats are so unhealthy.

When your body attempts to use the trans-fats in necessary physiological reactions, they won’t be effective.

Some of the numerous negative effects include: impairing heart performance, weakening your immune system, weakening the protective barrier around cells, and disrupting the function of essential fats.
Now that you have read the science, here is some additional practical information that will assist you to limit your intake of trans-fats. While it’s true that partially hydrogenated oil is a significant source of trans-fat, it isn’t the only one. Ѕіmрlу ехроsіng unsаturаtеd оіls tо hіgh tеmреrаturеs, lіkе whеn frуіng fооd, wіll аltеr dоublе bоnds аnd mаkе trаns-fаts. Since fats with many double bonds are rather fragile, they can be turned into trans-fats at much lower temperatures than fats with just one double bond (monounsaturated).
This is one reason a lot of folks advocate using olive oil in cooking. Olive oil is monounsaturated and potentially has some extra health benefits due to nutrients found in the oil. However, if you are cooking with very substantial heat, it’s in fact better to use a saturated oil, since there’ll not be any prospect of producing trans-fats during the cooking process. Regardless, try to prevent cooking with polyunsaturated oils rather than use liquid Omega-3 oils in cooking.
I hope this does not scare you away from eating fish because fish fats are among the healthiest things you can eat. Just make certain to minimize the amount the fats are damaged or altered by cooking the fish at a very low temperature for the shortest time possible. It is usually easy to tell if these fats are going bad since the fish will develop a fishy odor. Contrary to what many people believe, fish isn’t supposed to smell fishy. The fishy smell is truly the odor of the fat turning rancid.
