PUFAs are poison

When one consumes PUFAs like the omega-6 linoleic acid, it must be transported within lipoproteins (LDL, HDL, VLDL, chylomicrons) and then can accumulate inside fat tissue cells or on the fat cell membrane where they are constantly exposed to free radicals that are produced by normal metabolism and production of cellular energy.
In this scenario, your body is a sitting duck. You cannot avoid the free radicals, but you can surely avoid consuming PUFAs.
