Hydrogenation converts natural oils into shelf stable PLASTICS. To quote Dr. Edo Erasmus from his book, Fats that Heal, Fats that Kill, "Hydrogenation changes the unsaturated and essential fatty acids present in a natural oil.

In this process, oils are reacted under pressure with hydrogen gas at high temperature (120-210 deg. C or 248-410 deg F) in the presence of a metal catalyst (usually nickel, but sometimes platinum or even copper) for 6 to 8 hours. A ''nickel' catalyst often used in hydrogenation, called 'Raney's Nickel', is actually 50% nickel and 50% aluminum. Remnants of both metal remain in products containing hydrogenated or partially hydrogenated oils, and are eaten by people."

But before the damage of hydrogenating is done, there is the process of getting the oil from the seed in order to begin hydrogenating. Here, we remove all proteins, all fiber, about 95-99% of all minerals, 65-100% of all vitamins, almost all of the natural lecithin (which is a phospholipid), phytosterols, and other minor components [BTW, lecithin, which comes from many sources other than soy, is critical for liver detoxification, cell structure, function, and communication, skin structure; the list goes on from there. Also, without it, fat and fat soluble nutrients cannot effectively be transported to our cells]. As if losing all these nutrients where not enough, most processing techniques damage some of the essential oils leaving trans-fatty acids. Then there is the toxic by products of heat and pressure created from squeezing the oil from the seed as well as natural toxins found in cheaper oil sources.
