Guy on youtube video says extra virgin olive oil is bad... he tested it himself so it must be true.
Mercola is one of the biggest quacks on the internet and he is interviewing the head of a supplement company, i'd take anything they say with caution. I usually find dismissing anything Mercola says saves a lot of time. He occasionally gets things right, but only by accident.
Moerck's company sells the antioxidant astaxanthin for you to add to your olive oil.
Moerck sells krill oil and also happens too say fish oil is bad and that krill oil is better.
People like this are always happy to scare you into believing that something is bad for you, while selling you an expensive solution at the same time. They need to keep people worried so as ato keep them buying their expensive products. But then maybe i'm just cynical.
I thought i'd add some more info.
1) EVOO goes rancid faster than
minimally processed olive oil due to
it's high chlorophyll content.
Extra virgin olive oil does contain some chlorophyll, upto 6-10 parts per million from my reading, so not a high amount. Chlorophyll can increase oxidation in placed in bright light but can also prevent oxidation in the dark as the chloroplasts contain antioxidants. EVOO naturally contains antioxdent phytochemicals that refined olive oil does not. It also starts out with lower levels of peroxides than refined oils.
Adding a coloured antioxident astaxanthin to the oil would not show when the oil had become oxidised, only that the astaxanthin have been used up, this should have prevented some oxidation of the oil.
Light increases oxidation of olive oil of any kind, this applies to most fats. In an ideal world all EVOO would be sold in dark glass bottles to block out light. Keeping oil cool and in the dark will slow oxidation. I expect the clear bottles are due to most consumers wanting the see the colour of the oil when they buy it, most would probably find a green or brown colour off-putting. Leaving the lid off the bottle for few minutes is not going to ruin the oil.
I don't have time to dig out references as they are all in obscure journals. This site has some good information though - http://www.oliveoilsource.com/page/chemical-characteristics
Also notived that the guy being interviewed in the video does not seem to know there is a difference between palm oil and coconut oil.
