mmm... french fries

But in reality, what doesn't?

Googling "french fries" in the news section, there were quite a few articles explaining that soaking potatoes before making them into french fries can remove an acrylamide risk, whatever that is. Block quote time:

Acrylamide is a carcinogen that is created when starchy foods are baked, roasted, fried or toasted. In 2002, when scientists at the Swedish Food Administration first reported unexpectedly high levels of acrylamide, found to cause cancer in laboratory rats, in carbohydrate-rich foods. ^{[Food Navigator]}

Basically what it is saying, is that you should wash your potatoes (with moving water to remove 28% of the acrylawhatever, or soak them for a half-hour to remove 38%^{[LA Times]}) before you french-fry them.

Which I am pretty sure people do normally, since 9 times out of 10 you are supposed to wash your vegetables before you use them anyway.
