Ever wonder what your French fries were fried in? Like bumbling burglars who leave fingerprints 1 at a crime scene, cooking oils leave their own clues. And by measuring the carbon isotopes 2 in French fries, University of Hawaii researchers found that one oil tops all others as the choice to fry fries in: corn oil. That’s according to a report in the Proceedings 3 of the National Academy of Sciences.


National chain restaurants typically reveal only that fries may contain one or more of the following oils: corn, canola, soybean, cottonseed, sunflower and palm. But consumers might like a little more info: in a meal of burger, fries and soda 4, 20 percent of the total calories come from the oil that fried the potatoes.


Analyzing 5 fries from nearly 200 Hawaiian restaurants, the scientists found that 69 percent of the national chain outlets 6 used corn oil, compared with just 20 percent of independent eateries.


Corn oil is probably the least healthy of the oils mentioned, with more harmful saturated 7 fats than canola or sunflower and fewer heart-healthy compounds than soybean. Of course, regardless of what they’re fried in, French fries probably aren’t on your diet. Then again, you’re probably not on your diet either.
