| You are wrong, there's nothing indicating that PUFAs are as problematic as sugar or even problematic at all, on the contrary the evidence we have show they are beneficial. It concerns me that your comment is the top voted, as it can lead to dangerous dietary extremism, say avoiding all PUFAs which are among other things implicated in helping the immune system "Paracrine interactions between adipose and lymphoid tissues are enhanced by diets rich in n-6 fatty acids and attentuated by fish oils. The latter improve immune function and body conformation in animals and people. The partitioning of adipose tissue in many depots, some specialised for local, paracrine interactions with other tissues, is a fundamental feature of mammals."https://pubmed.ncbi.nlm.nih.gov/15946832/ 1. You shouldn't just throw in links to "support" your claims - to me this shows you don't understand what you're talking about, you should cite the relevant text otherwise it's just hand waiving. The studies you cite are about radicals generated from PUFAs that are naturally a part of cell membranes, not from diet, and even goes against your claim by saying that PUFAs from diet help generate antioxidants that eliminate such radicals. "Any change in the cell membrane structure activates lipoxygenases (LOX). LOX transform polyunsaturated fatty acids (PUFAs) to lipidhydroperoxide molecules (LOOHs)." i.e. cell membranes naturally have PUFAs."..."In order to remove LOO* radicals, plants and algae transform PUFAs to furan fatty acids, which are incorporated after consumption of vegetables into mammalian tissues where they act as excellent scavengers of LOO* and LO* radicals." - hey eating PUFAs help cells make radical scavengers. https://pubmed.ncbi.nlm.nih.gov/17914157/ 2. Omega-3 is a polyunsaturated fats - yes they are less stable than SFAs, but that probably does not matter at all unless you're eating rancid oils. Polyunsaturated fats are not "extremely" reactive either whatever you mean by that. Then we know that diets rich in PUFAs and MUFAs have positive effect on cholesterol ratios "We conclude that a mixed diet rich in monounsaturated fat was as effective as a diet rich in (n-6)polyunsaturated fat in lowering LDL cholesterol.
