studies have found that soybean
oil,
canola oil (and vegetable oils as they typically contain soybean /
canola oil) significantly affect the expression of many genes that metabolize drugs and other foreign compounds that enter the body, suggesting that a soybean

study found that vitamin E was significantly depleted using conditions designed to replicate use for deep frying, and another
study found that production of a toxic volatile compound called acrolein by
canola oil at 180 °C was found to be around five times higher than acrolein production by either extra virgin olive
oil or olive
oil, most probably due to the high ALA content of
canola oil and fewer antioxidants than olive
oil.
One thing to note about most of these
