Ray Peat said:"An important function of coconut oil is that it supports mitochondrial respiration, increasing energy production that has been blocked by the unsaturated fatty acids. Since the polyunsaturated fatty acids inhibit thyroid function at many levels, coconut oil can promote thyroid function simply by reducing those toxic effects. It allows normal mitochondrial oxidative metabolism, without producing the toxic lipid peroxidation that is promoted by unsaturated fats.” Dr. Ray Peat, Ph.D
