What is oleic acid but a monounsaturated fat. It is found in particularly large amounts in olive oil; hence the similarity of their names. It has been associated with the better health experienced by those folk living in winter rainfall Mediterranean climates where olives flourish.
The particular interest of chiropractors in oleic acid is that it is the primary substance in the myelin sheath that enables conduction of impulses by nerves.
Demyelinating diseases like MS attack the myelin sheath and prevent conduction causing paralysis among other signs.
You have probably heard of omega 3 and 6 fatty acids; they are essential oils that we cannot live without. They are both polyunsaturated; that means they have more than one double bond.
Oleic acid on the other hand is an omega 9 fatty acid. It can be manufactured from ω3 and 6. It is monounsaturated; it has only one double bond.
The numbers 3, 6 and 9 refer to the position of a double bond in the molecule.
Whilst the omega 6 fatty acids are "essential", we cannot live without them, they are in many instances pro inflammatory. Thus they should be consumed, but in moderation. Using large amounts of sunflower oil for example, will promote aching joints and muscles, polymyalgia and inflamed blood vessels.
Using no sunflower oil may be equally problematic if it causes a deficiency of these essential fatty acids; all things in moderation.
Thus large quantities of olive oil, and smaller amounts of sunflower for example is what is recommended.
What is oleic acid but the main constituent of olive oil. Oddly it is not an "essential" fatty acid, but it is unquestionably the healthiest fat in our diets, omega-3 fats excepted.
It is also found in large amounts in avocados; together with the olive they make up the "fruit" sources of fats. Seeds and meat are the other sources of fat, but they are less healthy, but still required in small quantities.
This is probably as clear as mud.
In short, we should enjoy
Large amounts of oils rich in oleic acid have been clearly shown to raise the healthy HDL fats whilst lowering the unhealthy LDL fats that are associated with atherosclerosis.
Peripheral neuralgias are a common affliction in older folk; numbness and tingling in the feet and lower legs are the most common symptoms. It may feel that you have gloves or stockings on. It can also cause motor signs such as weakness in one or many muscles. Diabetes for example has a prediction for the quadriceps in the thigh by reducing the blood flow to the nerve supplying the muscle.
Many of these peripheral neuralgias are poorly understood; some are autoimmune disease in which the body defence system attacks the myelin sheath of our own nerves. It is hypothesized that trans fatty acids used in the myelin sheath may be part of the problem; normally speaking our bodies use only the cis isomer.
It can be a sign of lumbar spinal stenosis.
In short oleic acid is a healthy fat found abundantly in meat, seed, nut and fruit oils. Monounsaturated oils like oleic acid in the diet have been associated with lower LDL cholesterol, and higher healthy HDL; they are associated with better health.
Generally it is found not as free oleic acid, but as the triglyceride of the fat.
However, too much fat in the diet is not healthy and is associated with many diseases; that would include the oleic acid in olive oil.
Olive oil only goes rancid very slowly, releasing trans forms; that's one of the reasons why it is so healthy. Having opened a bottle, do finish it within a month or so, however.
Chiropractic help concerns itself with issues such as those surrounding the fats in our diets, because patients are daily consulting us with nerve type symptoms; what is oleic acid is a question that faces every patient in pain.
Some of them are directly related to dietary issues, and are not pinched nerves at all; having some understanding of what is oleic acid may help some of your aching joint problems. It's certainly heart friendly in any case.
Olive garden nutrition sets out in a layman's terms the mystery of the different oils. What's the difference between mono and polyunsaturates? What are the dangers of going on an extremely low fat diet? What is oleic acid?
The virtues of olive garden nutrition in general, and the specifics of what is oleic acid is not rocket science; the information has been around for decades.
Of course, you don't have to understand how a car works to drive and enjoy it; if you have no desire to grapple with these issues, then just use more olive garden salad dressing and, if you're a baker, make this olive bread recipe.
Avocado fat is a wonder. Weight watchers used to ban it completely, but have changed their minds since grasping the importance of what is oleic acid. In any case, most of us are obese not because of too much oil in our diet but due to refined carbohydrate. If you regularly eat white rice, refined bread and cookies, and drink colas you will be too large.
Try to enjoy at least two avocados per week in season. For the rest of the year you need olive oil to satisfy the what is oleic acid equation.
Olives and avocado fat is where oleic acid is to be found in abundance; they are both fruit rather than seed or nut oils.
