What are Seed Oils, Really?
Let’s talk about seed oils—these sneaky little ingredients are hiding in so many of the foods we eat, and most of us have no idea how they’re affecting our health. Seed oils are extracted using high heat and chemical solvents like hexane (sounds delicious, right?). The process starts with cleaning and grinding up the seeds, then blasting them with heat to squeeze out every drop of oil. But because the oil is unstable and prone to oxidation (which basically means it goes bad easily), it has to be refined even further. This involves deodorizing, bleaching, and stripping away any impurities—along with any nutrients that might have been in there. What's left? Trans fats and other harmful byproducts.
These oils are loaded with omega-6 fatty acids, especially linoleic acid. And while a little omega-6 is fine, too much of it throws your body’s balance way out of whack. Ideally, we want a healthy ratio of omega-6 to omega-3 fats (the anti-inflammatory heroes), but modern diets are overflowing with omega-6s, leading to—you guessed it—chronic inflammation. This type of inflammation is linked to all kinds of issues: heart disease, weight gain, diabetes, and other serious health problems.
Also, for clarity’s sake (this confused me early on in my journey), “vegetable oil” is the umbrella term for all the seed oils.
