“Substances very much like the prostaglandins, called isoprostanes and neuroprostanes, are formed spontaneously from highly unsaturated fatty acids, and are useful as indicators of the rate of lipid peroxidation in the body. Most of the products of lipid peroxidation are toxic, as a result of their reactions with proteins, DNA, and the mitochondria. The age-related glycation products that are usually blamed on sugar, are largely the result of peroxidation of the polyunsaturated fatty acids.” -Ray Peat
