does re-using cooking oil cause cancer?

Question

i heard that it does, like using it for one thing then using it again to heat a diferent food?

Answer 1

I've never heard of it causing cancer.... typically one would use cooking oil once, the exception being a deep fryer.... any reputable restaurant should change the oil at least 2X's a week depending on the volume of business and fried food served. They should also make it available to oil recyclers who collect spent fryer oil and use it to make 'bio-diesel' which prevents the oil from entering landfills and is a viable, yet still new fuel source.

Answer 2

Normally it does not. But i saw a report some years ago that cooking oil much reused could. Many people have the habit of retaining the oil after the frying is done. this condition should be avoided. Basically no cooking oil is a carcinogen.
