As an industry pioneer and author of more than 35 nutrition-based books, I have long noted the unique properties of both quality and forbidden Omega-6 oils and fats. Understanding them is vital to leading a healthy lifestyle. Let’s take a closer look at why many seed oils do not deserve the negative press they’re getting these days.
Why Do Seed Oils Get a Bad Rap?
Understanding Seed Oils
Unadulterated and unrefined seed oils contain the GLA raw material, cis-linoleic acid, which the body converts to useful GLA (gamma linoleic acid). GLA, in turn, produces the eicosanoid E1 (known as PGE1) and, to a lesser degree, PGE2. When the cis-linoleic acid is heated, refined or adulterated with chemicals, it interferes with the transformation of GLA into eicosanoids. Without the ability to transform into eicosanoids, the essential fatty acids are biologically worthless.
There are several other factors that hamper eicosanoid production by blocking the enzyme (Delta-6 desaturase) that transforms GLA into useable and functional eicosanoids. These enzymatic co-factors include such vitamins as B-3, B-6, and C as well as the minerals magnesium and zinc. Aging, alcohol, and high blood sugar similarly work to hamper eicosanoid production.
Seed Oils in a Healthy Diet
So now that we understand that it is essential to consider the quality of seed oils within the context of a healthy diet, we can take note of how they can best be utilized. When purchased as organic and expeller pressed, it is fine to add small amounts of any seed oil to salads or to drizzle on veggies.
