A New Warning About Olive Oil

  • 3 of 4

Clearly, consuming spoiled oil (of any kind) will likely do more harm than good.

To protect the oil, Dr. Moerck recommends treating it with the same care as you would other sensitive omega-3 oils:

  • Keep in a cool, dark place
  • Purchase smaller bottles rather than larger to ensure freshness
  • Immediately replace the cap after each pour

To help protect extra virgin olive oil from oxidation, Dr. Moerck suggests putting one drop of astaxanthin into the bottle. You can purchase astaxanthin, which is an extremely potent antioxidant, in soft gel capsules. Just prick it with a pin and squeeze the capsule into the oil.

The beautiful thing about using astaxanthin instead of another antioxidant such as vitamin E, is that it is naturally red, whereas vitamin E is colorless, so you can tell the oil still has astaxanthin in it by its color.

As the olive oil starts to pale in color, you know it’s time to throw it away.

You can also use one drop of lutein in your olive oil. Lutein imparts an orange color and will also protect against oxidation. Again, once the orange color fades, your oil is no longer protected against rancidity and should be tossed.

This method is yet another reason for buying small bottles. If you have a large bottle, you may be tempted to keep it even though it has begun to oxidize.

The Worst Cooking Oils of All

Polyunsaturated fats are the absolute worst oils to use when cooking because these omega-6-rich oils are highly susceptible to heat damage.

This category includes common vegetable oils such as:

  • Corn
  • Soy
  • Safflower
  • Sunflower
  • Canola

Palm Oil - Health: Blood Lipid and Cholesterol Effects
The U.S. Center for Science in the Public Interest said Palm Oil (high in saturated and low in polyunsaturated fat) promotes heart disease; Report cited Research going back to 1970; also said that The National Heart, Lung and Blood Institute, World Health Organization (WHO), and other Health Authorities urged reduced consumption of Palm Oil; WHO states that there is convincing evidence that palmitic acid consumption contributes to an increased risk of developing cardiovascular diseases. A 2006 Study by the National Institute of Health and the USDA Agricultural Research Service concluded that it's not a safe substitute for partially hydrogenated fats (trans fats) in the Food Industry, as Palm Oil results in adverse changes in the blood concentrations of LDL Cholesterol and apolipoprotein B just as trans fat does.

Palm Oil - Other uses
Palm Oil became a highly sought-after commodity by British traders, for use as an industrial Lubricant for machinery during Britain's Industrial Revolution; the basis of Soap products, such as Lever Brothers' (now Unilever) "Sunlight Soap", and the American Palmolive brand; derivatives of palmitic acid were used with naphta during World WarII to produce Napalm; to create Biodiesel.

Palm Oil - in the Cooking Industry
A common cooking ingredient in Africa, Southeast Asia and parts of Brazil. Since Palm Oil is of a lower quality than Olive Oil, it remained rare outside West Africa. Its increasing use in the commercial Food Industry... because: 1) Palm Oil has the LOWEST Production COST of the major Oils, and 2) Products last more time in the Supermarket shelves!! for the high oxidative stability (saturation) of the refined product when used for frying. Many processed foods contain Palm Oil but it is NOT DECLARED on Labels!!! Or Label simply says: "Vegetable Oils"!! Try to read a Chips Packet Label, just as an example!! This is a real offence to all of us, but particularly to VEGANS and VEGETARIANS devoting their lifestyle not to hurt animals, while, like all customers, they are unwillingly and unconsciously contributing to the SLAUGHTER of Tigers, Elephants, Rhinos, Wildlife... and GENOCIDE of Orangutans, who share 98% DNA with us!!!

Palm Oil & Olive Oil:
One of the BASIC Principles of the "Mediterranean Diet" is PURPOSELY Olive Oil, that contains also Vitamin E, i.e.: also antioxidant properties!! My husband, English, went to the Hospital in Dorset, UK, where his Father had just been saved from a heart attack, undergoing an operation in which a triple Bypass had been placed. Heart attack had been the same cause of death for my husband's two Uncles and his Grandmother; & his mother being saved with a Pace-maker. After his father's operation, at the Hospital, the English Cardiologist, ASKED my husband to immediately shift to a "Mediterranean Diet" & use Olive Oil, just for healthy living and in order to prevent Cardiovascular Diseases!!!

Olive oil in the headline. Coconut oil article though. Just be aware. Smaller bottles is a good tip.

I totally agree with Dr Mercola. BTW, The New York Times recently published an explosive article entitled “Extra Virgin Suicide.” It reports that much of the olive oil sold in your local supermarket is adulterated with cheap soybean and other inferior oils. That's very disturbing because most soy oil comes from genetically modified soybeans. Yuck! American supermarkets have become dumping grounds for these fraudulent oils. Yet it's almost impossible to police these shady foreign operators because they are beyond the reach of U.S. regulators.

Check this out...
NBC News reports that “fake olive oil is rampant.”

CBS News adds: “Consumers who think they're buying one of the healthiest foods on the planet often get something very different.”

“American grocery stores are awash in cheap, fake ‘extra virgins,’” confirms The Wall Street Journal.

A feature story on ABC’s Good Morning America was headlined, “Olive Oil Fraud Rampant.”

Forbes magazine warns: "Here's the hard truth: the olive oil in your pantry, the one you bought for its health benefits and for some sliver of the seductive Mediterranean lifestyle, is most likely a scam."

Agree with Ann M. about having to plod through four pages.
Still believe in extra virgin olive oil.
