Many people have learned that seed oils (soybean oil, canola oil, corn oil, sunflower oil, safflower oil, cottonseed oil, etc.) are not good for you. For better health, olive oil and avocado oil are preferred.
So companies have started making products with only olive oil and avocado oil. Even though these products are much more expensive, people are buying them for the promise of no seed oils.
The problem? The companies are not honest. They attach labels to these products claiming 100% avocado oil, or 100% olive oil, but it just isn't true.
The University of California at Davis published a study about a month ago in which they tested a number of food products for authenticity and label accuracy.

Here is an executive summary: https://UCDavis.App.Box.com/s/6ogs4l0ogplunooktwryr5b1m6k2xr9u/file/2347698985551
In this summary, a checkmark in the far right column is good. The lack of a checkmark is bad, indicating false labeling.
You get what you deserve if you're buying commercially processed foods.
Do you press your own olives‽ that would be crazy cool
That would be fun, but I actually trust the label on a can of olive oil.
Lay's? Not so much.
Only buy Olive oil in a GLASS container, not a "can".
( Same with Avocado, or Coconut oil = different purpose)
Can is a generic term in this case.
Also, make sure it's a green or amber glass, not clear as UV light will make it go rancid faster.
