Why Trans Fat Is So Bad – and What Is It, Anyway?

Why Trans Fat Is So Bad - and What Is It, Anyway?

Trans fat isn't crooked—and that's the problem. Though it's chemically identical to natural fats, it doesn't bend. Here's a clear and simple explanation of why, what it means, and why trans fats are so dangerous.

Woman with Out of Order Sign on Head

We have been indoctrinated about fats for decades. Starting in the 1950′s, we were inundated with ads about how bad saturated fat is. We were, and still are, advised by our doctors to avoid butter and use margarine, or better yet, avoid fats altogether. Fairly recently, conflicting information has been coming out. Polyunsaturated fat is good...no, it's bad. Monounsaturated fat is good. Fat that's solid at room temperature is bad. No, coconut oil is good...and so forth.

So, what's the truth? Fat is good for you!

At least 25% of your calorie intake should be comprised of it. As you know, veggies are good for you, and if fresh, their oils are healthy, too. With that undeniable fact, it's been an easy sell to convince people and their doctors that we should avoid saturated fats and eat veggie oils—with "in moderation" tagged on to pay lip service to the (misbegotten) idea that we should keep fat out of our diets. The catch is that little word, fresh. It's virtually impossible to get fresh vegetable oil to the supermarket shelf. It goes rancid in no time at all. Therefore, it's processed by hydrogenation.

This technique keeps the vegetable oil from rapidly going rancid, making it profitable to store and sell. There is, of course, a price paid for this agribusiness profit—your health.

Isn't it interesting that, just as the medical system started telling us that we need to avoid saturated fats and use vegetable fats is when heart disease started to skyrocket? To fatten agribusiness pockets, we were told to avoid the fats that are good for us, and eat processed junk fat.

The Differences in Unsaturated, Saturated, and Trans Fats

Saturated Fat Molecule

To understand this better, let's first take a look at what saturated fat is. As shown in the image to the right, the term describes fat molecules in which all possible hydrogen bonds have been made. That means that every carbon atom in the molecule is paired with one or more hydrogen atoms, so it's loaded to capacity—saturated—with hydrogen. (The full picture is complicated by whether the carbon has double or single bonds, but it's not necessary to get into that detail to describe the distinctions that we're concerned with here.)

Cis Fat Molecule

Unsaturated fat molecules have a characteristic, called cis. (Image above.) The term cis means that atoms are located on the same side of a molecule. Trans means that identical atoms are located on opposite sides of a molecule.

Because the hydrogen atoms of naturally unsaturated fats can be on the same side, they tend to repel each other. This results in a bend in the molecule, making the molecule more available for bonding with others.

Trans Fat Molecule

Trans fats are formed by forcing hydrogen through fat at high heats. (They are not formed by cooking alone.) This results in hydrogen being bonded on opposite sides of the molecule, as shown in the image to the left. Because they're not adjacent to each other, the hydrogen atoms do not repel each other, so the molecule does not bend. The molecule is, therefore, more stable, not as readily able as cis fat molecules to bind with the atoms of other molecules.

What difference does a bend make?

It would seem that a little bend wouldn't matter, since the saturated fat molecules and trans fat molecules are chemically identical. The first thing to understand is that cell walls consist of about 50% saturated fat. When we eat trans fats, they can replace the saturated fats in cell walls.

Cell walls can, and must, be permeable—but only to the right degree. Nutrients pass through the cell wall into the cell, while wastes and toxins pass through them in the opposite direction to be removed from the body.

Because trans fats are more stable chemically—the direct result of the hydrogen atoms being on opposite sides of the molecule—they do not interact properly with other molecules. The cell wall itself is not as tightly bound as it should be, making it weak and more permeable than normal. Thus, molecules of toxins that would have been too large to enter a cell may now be able to squeeze through the cell wall and wreak havoc inside.

Many substances move in and out of cells via messages exchanged through the cell wall. They function by chemical signals or exchanges, or by shape. Trans fats are less chemically active, so the proper signal exchanges cannot be made and normal cell communication cannot occur. Trans fats are also shaped differently, so molecules can be stuck either inside or outside the cells. When trans fats replace saturated ones, critical nutrients may not be able to enter cells and toxins may not be able to exit.

The result is a deranged metabolism, which affects every aspect of health.

Aside from composing half of cell walls, saturated fats play many other important roles in the body. They're needed for energy, hormones, and signaling, such as communication to allow or refuse entry to a cell.

Hormonal signals, such as adrenalin in the fight-or-flight response, may not be properly received and acted upon. In a real emergency, one's reflexes and ability to run can be jeopardized. In the modern world's typical high-stress environment, the body's inability to respond to adrenalin may result in the adrenal glands pushing even harder to produce more and more adrenalin. A common problem today is adrenal fatigue, which can lead to thyroid malfunction. It's certainly not surprising that women are experiencing an epidemic of thyroid burnout.

Prevalence of Trans Fats

When you see the term trans fat, you should immediately think of hydrogenated fat. When you see the term hydrogenated in any context, you should think trans fat. The bottom line is that they all refer to the same process of hydrogenation, which not only destroys the quality of food, it makes it dangerous.

Partial hydrogenation is done to increase shelf life of oil. Vegetable oils are quite healthy when they're fresh. That is, though, the rub. They go rancid quite rapidly, making it virtually impossible to get them to supermarket shelves and store them long enough for sale. Therefore, you must assume that they have been partially hydrogenated. They have gone through the same process, but not as extensively. As a result, the oil is stable, so it takes a very long time to become obviously rancid, but it's now a poison.

Trans fats, whether fully or partially hydrogenated, are not simply foods from which nutrition has been leached. They're poison. To suggest that partially hydrogenated oils are okay is like suggesting that it's better to take one poison because it's less poisonous than another. Both are poisons. When you consider how heavily vegetable oils have been pushed—virtually defined as the key to good health—it isn't difficult to see why cancer, heart disease, and many other chronic diseases have become so common.

All Polyunsaturated Fatty Acids Dangerous



It should be mentioned that all polyunsaturated fatty acids exert an anti-thyroid effect on humans and all other mammals. That fact has been long known but suppressed by the processed food industry and the agriculture industry. Corn and soybean oil fed to pigs and cattle on Confined Feedlot Operations impairs their thyroid function causing them to develop fat-infiltrated muscle mass thereby weighing in heavier at slaughter.

Polyunsaturated fats also impair immune function. There is a history in the medical industry of organ transplant recipients being dosed with polyunsaturated plant oils prior to surgery in order to suppress the immune response thereby decreasing likelihood of organ rejection.

Polyunsaturated fats are also long known to be carcinogenic. This has been known since at least the early years of the Framingham heart study when study participants were advised to eat margarine and corn oil for heart health and suffered a significant increase in cancer as well as increased cardiac disease. Analysis of atherosclerotic arterial plaque reveals polyunsaturated fats as the primary component.

At the beginning of the 20th century, people had been consuming  traditional saturated fats such as beef tallow, lard, bacon fat, butter, palm and coconut oil for hundreds of years. Cancer and heart disease were rare. There was no business for cardiologists and oncologists.

The onset of World War II brought rationing of butter, beef and bacon which was sent to the troops. Coconut and palm oil was not available due to the Japanese blockade in the Pacific. This opening allowed the grain oil producers to flood the market with cheap polyunsaturated oils which were marketed for the "modern housewife" while all sorts of fraudulent health claims were made and continue to be made to this day. Prior to this development, these oils were used to make paints and varnishes. No one in their right mind would have thought of eating them.

This is just one more example of how corporations have produced disease for profit. Uncontaminated saturated fats are necessary to provide the precursors for all hormones produced by the endocrine glands... that means sex hormones, thyroid hormones, adrenal hormones, etc. Saturated fats are necessary for healthy cell membranes and a myriad of other bodily functions including brain and nerve health. Saturated fat is absolutely necessary for a healthy immune system.

I advise going to your pantry and throwing out all corn oil, soybean oil, safflower oil, sunflower oil; essentially all grain and seed oil. I recommend only the following virgin oils: the medium chain saturated oils coconut and palm oil; the mono-unsaturated oils: olive oil, avacado oil, macadamia nut oil. Beef tallow, lard, and butter are all good if they come from organic grass-fed pastured animals.

Personal experience



I developed a tendency to become excessively and scarily exhausted, to the point of pain, when I would run up a small hill, particularly if I did not get good sleep.  (Age: 67).  I figured that it had something to do with my nervous system, since it did not happen at all when I got good sleep.  I could even sprint up the same hill 10 times as exercise when I got good sleep; no rest between sprints other than walking down the hill.

I upped my saturated fat intake dramatically deliberately.  The problem went away.  No one will ever be able to convince me that saturated fats are bad.

Error in Molecular structure



I don't disagree with the major tenants of this article, however, some loss of confidence in those with a chemistry background is probable when it is recognized that a double bond between carbon and a hydroxyl group (-OH) is not viable.  Oxygen has 6 electrons and thus can participate in two covalent bonds with two shared electrons each in order to complete an 8 electron membered shell.

Re:Error in Molecular structure



You are correct, and I do apologize for the error. It just goes to show what rushing to get the job done accomplishes.  The Cis and Trans fatty acid images should be replaced soon.

Thank you for bringing it to my attention.

Cellular Healthiness



It would be useful if we could measure cellular healthiness.  We shed lots of cells daily and it should be relatively easy, in theory, to collect some and measure their 'fat healthiness', for example. That would provide an interesting view into the health of different people on different diets. 

Measure Cells' Healthiness



Hi Tracy, Any measure of inflammation, oxidative stress like CRP, ferritin, fibrin, ORP, pH, etc., indicates a problem with membranes, electrolyte levels or toxins/metals...O2 levels and body charge go hand in hand. Bad fats and an electron/oxygen poor internal environment top the list of causes, but the problem needs to be addressed holistically 'cause the head bone is connected to the neck bone, yadayada.

CCold pressed extra virgin Olive Oil



You do not mention (unless I have missed it) Olive Oil which has been a healthy staple of the Mediterranean diet for ages???

Suffocation



   Damaged oxidized misshapen rancid fats comprising cell membranes are a major health hazard since they transport oxygen poorly and prevent energy production which normal biochemistry relies on. Damaged fat molecules are poor conductors of electrons (electricity) and once membranes have been misconstructed of them or oxidized in situ, the organism suffocates, oxidative stress flares and a downward spiral into disease commences. This is a main cause of bad health among a clueless population and medical community living in the box of cholesterol mythology. A government protected faux-food industry only feeds pharma-care and the funerary sectors, not humans who have become incidental in the chain of corporate profits...Don't drown.
