It would certainly be worse if the fat were well dissolved in the

water rather than separated, but there is no way that the fat is not

being heated, and at the top of the pot it's going to have plenty of

exposure to oxygen, so there's bound to be some oxidation.

That said, even fresh, unoxidized PUFA increases oxidative stress

because they become oxidized within your cell membranes and within

lipoprotein particles, so while I think it is worse to eat rancid

oils, you still don't want to load up on fresh PUFA.

Thanks for the reply Chris.

I did not mean to imply that the fats were not being exposed to heat or air,

rather that the degree of damage may or may not be lessened by the presence of

water.

Why do you state that if the fat were dispersed in the water it would be worse?
