Summary
Consuming partially hydrogenated oils is like inhaling cigarette smoke. They will kill you -- slowly, over time, but as surely as you breathe. And in the meantime, they will make you fat!
The first thing to understand about fats is that the essential fatty acids they contain are truly essential. They are the "active ingredient" in every bodily process you can name:
In short, the essential fatty acids (contained mostly in polyunsaturated oils) are the most important nutrients there are -- more important than vitamins, minerals, or even proteins. Without essential fatty acids there is no life. They are the substance and foundation of life energy.
Hydrogenation is the process of heating an oil and passing hydrogen bubbles through it. The fatty acids in the oil then acquire some of the hydrogen, which makes it more dense. If you fully hydrogenate, you create a solid (a fat) out of the oil. But if you stop part way, you get a semi-solid partially hydrogenated oil that has a consistency like butter, only it's a lot cheaper.
Because of that consistency, and because it is cheap, it is a big favorite as a butter-substitute among "food" producers. It gives their products a richer flavor and texture, but doesn't cost near as much as it would to add butter.
Note:
Until the 1970's, food producers used coconut oil to get that buttery flavor and texture. The American obesity epidemic began when it was replaced with partially hydrogenated vegetable oil -- most often soybean oil.
Unlike butter or virgin coconut oil, hydrogenated oils contain high levels of trans fats. A trans fat is an otherwise normal fatty acid that has been "transmogrified", by high-heat processing of a free oil. The fatty acids can be double-linked, cross-linked, bond-shifted, twisted, or messed up in a variety of other ways.
The problem with trans fats is that while the "business end" (the chemically active part) is messed up, the "anchor end" (the part that is attached to the cell wall) is unchanged. So they take up their position in the cell wall, like a guard on the fortress wall. But like a bad guard, they don't do their job! They let foreign invaders pass unchallenged, and they stop supplies at the gates instead of letting them in.
In short, trans fats are poisons, just like arsenic or cyanide. They interfere with the metabolic processes of life by taking the place of a natural substance that performs a critical function. And that is the definition of a poison. Your body has no defense against them, because they never even existed in our two billion years of evolution -- so we've never had the need or the opportunity to evolve a defense against them.
Partially hydrogenated oils will not only kill you in the long term by producing diseases like multiple sclerosis and allergies that lead to arthritis, but in the meantime they will make you fat!
It's not like you have any choice in the matter. Remember that the essential fatty acids are vital to every metabolic function in your body. You will get the quantity of essential fatty acids that you need to sustain life, no matter what. You will not stop being hungry until you do.
If you are consuming lots of saturated fats, you really have no choice but to become fat, because saturated fats contain only small quantities of the polyunsaturated fats that contain the essential fatty acids you need. The key to being thin, then, is to consume foods containing large amounts of polyunsaturated oils. (Those foods include fish, olives, nuts, and egg yolks.) Over the long term, those foods remove your sense of hunger.
Note:
The difference between a "fat" and an "oil" is temperature. A "fat" is a lipid that is solid at room temperature. An "oil" is one that is liquid at room temperature. Both are lipids (or "oil/fat"). Change the temperature, and you can convert an oil into a fat, or vice versa.
Partially hydrogenated oils make you gain weight the same way that saturated fats do -- by making you consume even more fat to get the essential fatty acids you need. But partially hydrogenated fats are even worse. Not only do they produce disease over they long term, but they interfere with the body's ability to ingest and utilize the good fats!
Picture it like this. The trans fats are now the guards along the watchtower. The essential fatty acids (the support troops) are waiting outside to get into the fort (the cell), so they can be distributed along the watchtower (the cell wall). But the guards won't let them in! So they have to find someplace to stay in town. Over time, more and more troops are finding lodging in town. So new houses (fat cells) have to be built to keep them in. The town grows more and more swelled with troops (fat), and it gets bigger and bigger (fatter). It's not a pretty picture at all, when you realize that the town is your belly, buns, face, and neck.
Worse, most partially hydrogenated oil is partially hydrogenated soybean oil. That's a problem, because soybean oil depresses the thyroid--which lowers your energy levels, makes you feel less like exercising, and generally makes you fatter!
Of course, soybeans have been used for centuries in the Orient--but mostly as the basis for soy sauce and tofu. Asians didn't have soy milk, soy burgers, soy this and soy that. Most of all, they never used concentrated essence of soybean, in the form of soybean oil. And they didn't hydrogenate it, and they didn't use it in everything.
Walking down supermarket aisles in America, you find product after product with partially hydrogenated oil--often in products you would never expect. But why not? After all, it's cheaper than butter. And it's not illegal. Yet. When you eat out, restaurant breads and fried foods are loaded with stuff.
As a result, Americans are consuming soybean oil--partially hydrogenated soybean oil--in virtually everything they eat. It's no wonder that America is experiencing epidemic levels of diabetes, obesity, heart disease, and cancer.
So what do we do to avoid these bad fatty acids? This is what we will discuss in the second part of this article.
