i found an article about olive oil and it occured to me you could have bad stuff to begin with. read up at the link, everybody!
from the article:
Most people think that by purchasing "extra virgin" olive oil they are getting a high quality oil.
Unfortunately, in most cases, this is not true. It's more complex than that. A label reading extra virgin is no guarantee of quality. For one thing, nowhere does it say that extra virgin olive oil has to be made 100% from olives. An major criterion for grading olive oil is its level of acidity. Extra virgin oil should have a free oleic acid acidity of no more than one percent, whereas ordinary virgin olive oil can have an acidity of up to 3.3 percent.
Lower quality oils can be refined to bring the acidity down so they can be labeled as extra virgin. But now the oil has been refined, and that's not what you want. That's why being labeled extra virgin is no guarantee of getting high quality oil, which has not been processed in ways that reduce its nutritional value. To complicate matters even more, the term "extra virgin" has no official meaning in the United States. The U.S. is not a member of the International Olive Oil Council. So, olive oil sold here can be labeled extra virgin without meeting the accepted international standards.
Another reason why you can't trust extra virgin olive oil is exemplified by a problem that manifested last year, and may turn out to be the biggest food fraud of the 20th Century. Despite the fact that details of this scandal have been published in Merum, a Swiss-German magazine, and in Italian journals such as Agra Trade, and the newspaper Gazzetta del Mezzogiorno, this information has been successfully suppressed and is known to only a handful. Investigators are gathering evidence indicating that the biggest olive oil brands in Italy have for years been systematically diluting their extra virgin olive oil with cheap, highly-refined hazelnut oil imported from Turkey. International arrest warrants have been issued and so far documents indicate that at least ten thousand tons of hazelnut oil are involved. As much as 20% hazelnut oil can be added to olive oil and still be undetectable to the consumer. In fact olive oil labeled "Italian" often comes from Turkey, Tunisia, Morocco, Spain, and Greece. Considering what has happened in Europe, where there are strict regulations, imagine what can happen in California where there are no regulations. Apparently, more oil is "produced" in California than there are olives available. The truth is, most of the extra virgin olive oil on the market does not supply all the nutritional value and health giving properties that we have a right to expect from olive oil.
This is scary stuff when you consider how extremely important oil is to human health. Our modem chronic disease problems are the result of radically changing, in a short period of time, the fundamental parameters of human existence, namely: diet, environment, and behavior. One of the most fundamental changes in our diet has been the kind and the amount of fats and oils that we consume. For example, the consumption of hydrogenated oils has proved to be a disaster for human health. Hydrogenated oils have been implicated in both our cancer and heart disease epidemics. In fact, all modem processed oils are injurious to human health. To reverse our pandemic of chronic disease, we have to return to eating a more traditional diet, and high quality olive oil can safely be included in that diet. It's not so much that olive oil should be added to the diet as much as healthy, real olive oil should be used to replace the unhealthy, processed oils now being consumed.
there is much more to read and it is important stuff. this OO trick is great and the quality of the oil could make it yucky or fantastic. i found out i have really good estate bottled stuff. it even looks like a bottle of wine!
