I'm not disputing that. I'm disputing the completely unsubstantiated and simply ridiculous claim that 80% of olive oil isn't actually olive oil. That's a misreading akin to claiming that "80% of Halloween candy is pure sugar, and might even have a razor blade in it" means that 80% of Halloween candy has a razor blade in it.

Its a sad state of today's food products. Honey in particular is often fraudulent containing syrups and sugars to add to volume while still being marketed as "Pure Honey". Worst of all, it is getting harder to detect the authenticity in modern labs as "honey factories" continue to develop new ways to throw the test results.

If it's been packaged for longer than a month and is still liquid -- it's fake. Real honey crystallizes quite quickly.

Because to keep it from crystallizing, you have to filter it so hard that it is indistinguishable from fake honey laced with real honey.

> In Italy or Spain, you can find "non extra-virgin" olive oil sold as well

Also in the US, you can find both virgin olive oil and (no modifier) olive oil as well as extra-virgin (and while EVOO is a higher grade, its only better for a narrow range of applications.)
