šØ SHOCKING NEW STUDY: Nearly 9 Out of 10 āAvocado Oilā Foods Are Fake or Heavily Adulterated
A newly published investigation from UC Davis has exposed a widespread deception in the grocery aisle that will outrage anyone paying a premium for āhealthierā processed foods.
Researchers carefully extracted the oils from 74 commercially available chips, salad dressings, and mayonnaise products labeled as containing avocado oil (or olive oil for comparison).
Using gas chromatography to analyze fatty-acid and sterol profiles against established Codex Alimentarius standards, they discovered that 89% of the avocado-oil-labeled products had chemical signatures inconsistent with authentic avocado oil.
The results were especially stark by category: 93% of avocado-oil chip samples failed authenticity criteria, every single salad dressing tested failed, and 71% of the mayonnaise samples failed.
In total, only six of the 54 avocado-oil products examined were compositionally consistent with real avocado oil.
Many of the failing samples showed telltale markers of substitution or dilution with far cheaper vegetable oils (soybean, canola, corn, or sunflower) complete with elevated linoleic acid and sterol patterns that simply do not match genuine avocado oil.
Well-known brands such as Boulder Canyon, Siete, Kettle Brand, Jacksonās, Sprouts, Primal Kitchen, Chosen Foods, Sir Kensingtonās, and others appeared among the adulterated lots.
In one particularly egregious case, a productās fatty-acid profile closely mirrored soybean oil, with oleic acid levels far too low and polyunsaturated fats far too high for pure avocado oil.
By contrast, the olive-oil versions of similar products fared dramatically better, with 90ā100% passing authenticity checks⦠underscoring how weak the standards and regulatory scrutiny remain for avocado oil compared with its more established counterpart.
This is genuinely bad news for all of us who have been trying to make better choices.
So many people have deliberately sought out these avocado-oil products, paying extra and trusting the labels in the belief they were swapping out inflammatory seed oils for something cleaner and more nutritious.
Finding out that the majority of what we bought was likely diluted or completely substituted undercuts that effort and leaves consumers feeling misled after making what they thought were responsible decisions.
Consumers are being sold a carefully crafted marketing story of clean, premium, heart-healthy fats while frequently receiving diluted or substituted oils behind the label.
The study makes clear that the vast majority of these products do not deliver what the packaging promises.
Those paying extra for the avocado-oil claim appear, in most cases, to have been seriously misled.
