Fat and oil in our diet is one of the most widely misunderstood and confusing subjects when it comes to our health. Decades ago we were informed that a ‘low-fat’ diet was optimal for energy, health, and preventing nearly all diseases — especially heart disease. We were then informed that fats are crucial for health, yet also told that the best fats to consume are vegetable oils. Vegetable oils have widely been touted to help lower blood pressure, prevent heart disease, aid weight loss, and even help to lower cholesterol. Almost every product that contains vegetable oils has today been labeled as ‘Heart Healthy.’ But the truth is that consuming vegetable oils will actually destroy your health!
Vegetable oils are generally produced from seemingly healthy foods: from soybeans, corn, rapeseed (canola oil), safflower, sunflower, etc. Yet, if we think back 100 years, oils produced from these plants were non-existent. Technology had yet to be developed that would actually allow oil to be extracted from these plants. Especially in the case of soybeans and corn, think about eating a soybean or a kernel of corn. How much fat do they contain? Not much. In the early 1900s chemical solvents, usually petroleum based, were created that allowed oils to be extracted and separated from their whole-food form. These chemical solvents were (and are) cheap to produce, and could be applied to nearly any crop. Manufacturers applied these cheap chemicals to the cheapest crops, creating a large surplus of vegetable oil. Now vegetable oils are in everything: margarine, mayonnaise, salad dressing, roasted nuts and seeds, and almost every processed food!
Vegetable oils will destroy your health for two reasons: they way in which they are manufactured and their chemical makeup.
Because vegetable oils tend to be extracted from the cheapest of crops, they tend to derive from genetically modified (GMO) crops. In the case of canola oil, oil cannot be extracted from a non-genetically modified variety of rapeseed! The variety of rapeseed from which oil is extracted was specifically engineered to have oil extracted from it! I’ll have a future article on why to avoid GMOs, but know that genetically modified crops also tend to be the crops with the most heavily used pesticides and herbicides. Oil is a concentrated form of a food, thus oils have a much greater concentration of whatever pesticides and herbicides were sprayed on its whole-form!
When vegetable oil is extracted from it’s whole-form, it is extracted by heating the food and applying the chemical solvent. Waxy residues are created from this heat and chemical mixture, and must be removed by applying yet another mixture of heat and a chemical acid. If this doesn’t sound that tempting — it’s not. At this point, vegetable oils have an unappetizing color and smell. Manufacturers know this, so use even more chemicals to make the color more appetizing. This is followed by another chemical process to deodorize the oil. Such chemicals used in these processes include bleach and hexane, an extremely dangerous chemical known to be a neurotoxin and potent carcinogen (a cancer promoting substance). Residue from the chemicals required for extraction are found in vegetables. These chemicals combined with the pesticides and herbicides used for growing the crop create a vegetable oil that is, in actuality, a toxic concoction.
Vegetable oils by their chemical nature are mostly polyunsaturated fats. The chemical structure of polyunsaturated fats makes them extremely sensitive to heat: even a minor heating (such as light cooking) can damage the chemical structure, making them rancid and unfit for consumption. Vegetable oils are the most polyunsaturated of all oils! Yet the process required for extracting vegetable oil requires a high-temperature heating, not once, but twice! The reason oils smell unpalatable during manufacturing is because the oils have spoiled, they’re rancid. By using a deodorizing process, manufacturers cover up this reality. Rancid and spoiled oils are one of the most damaging foods you can consume. Rancid fats promote free radicals (those things anti-oxidants are supposed to help reduce), are toxic to the body (your body does not know how to eliminate them properly), and promote full-body inflammation (known to promote all major diseases and disorders).
Additionally, vegetable oils contains a large concentration of Omega-6 oils. While Omega-6 fats are important for health, the majority of people’s diets contain far too many Omega-6. A balance of Omega-3 and Omega-6 fats are required for health, but an overabundance of Omega-6 promoted an over-inflammation of the body. As mentioned above, inflammation is perhaps the single largest and universal cause of all major diseases and disorders, especially heart disease and high blood pressure.
So what oils should you consume? Sticking with traditional oils, oils that have been consumed for millenia, are the safest and most health promoting! Such oils include coconut oil, palm fruit oil, and butter. While these oils are saturated fats, they are not dangerous to your health! Check out all the benefits of coconut oil! The saturated chemical structure of these fats makes them more stable than polyunsaturated vegetable oils, and thus extremely safe and the oil of choice for cooking. And while olive oil is a vegetable oil, it is perhaps the only safe vegetable oil for consumption. Buying cold-pressed, extra virgin olive oil is your best bet, as the extraction process requires minimal heat and has been extracted for thousands of years without the use of chemical solvents.
Choosing the highest quality fats and oils in your diet will give you large gains in your overall health. Stick with traditional oils, and avoid vegetable oils that have only existed for a few decades, including eating the processed foods that contain them. You’ll find you feel better, reduce your risk for all major diseases, and you’ll probably enjoy them more, too!
