Question: What Is the Real Issue With Seed Oils?
Short Answer: The main issue with seed oils is that they present an oxidative liability. They do not acutely cause oxidative stress, but their polyunsaturated fatty acids (PUFAs) are more vulnerable than any other macronutrient to oxidative damage. Oxidative stress can increase because of nutrient deficiencies, toxins, infections, other sources of inflammation, alcohol, or smoking, and it will inevitably increase as a function of aging. As oxidative stress increases, more PUFAs in the tissues mean more damage. At least 0.6 milligrams of vitamin E should be gotten per gram of PUFA in the diet, but vitamin E cannot fully protect against PUFA, so their intake should be moderated to the very low levels needed, as obtained by eating fatty fish once or twice a week, eating eggs daily, and eating 4-8 ounces of liver per week. Additional secondary problems with them include residual solvents and heat damage prior to intake, but the main issue is that we do not want to increase our tissue PUFA content more than needed.
