Oh don't listen to Laundress, (LOL).
Actually, go to any Indian grocery store and pick up some coconut oil (solid white at room temp) or even some palm oil (any hesitation here and I would recommend the class review the movie "Dona Flor and her two Husbands"). Possibly the best freakin' french fries you'll ever eat. You won't live long afterward, maybe, but it' quality of life, not quantity.
Let me know, by the way, if you want my recipe for Philadelphia World's Fair doughnuts fried in Coconut Oil. And if any of you AW'ers ever get to New York City, make a bee-line down to lower Delancey street to the Doughnut Plant--honest to god the best doughnuts I've ever tasted outside of Germany. And right next store is a bakery that makes some of the best bialy's in the city. Ok, I have to go now and measure my blood sugar.
