You have to be careful about olive oil to avoid fake oil that is not what the label claims. I recently watched a video that described a mafia operation in Italy where they were buying up bulk quantities of low quality olive oil and other types of oil and putting it into expensive-looking bottles and shipping it to the US. There were a number of arrests, Italy is very strict about this. The US is apparently much less so. People say fakery abounds.
I have read that oils from California are more likely to be the real thing.
I have only recently started taking olive oil, so I am not claiming to be an expert. I recommend doing some research on YouTube, or elsewhere.
