The Truth About Seed Oils
Alright, folks, let’s talk about seed oils—the so-called “heart-healthy” oils lurking in your pantry, your favorite snacks, and pretty much everything that comes in a package. Spoiler alert: they’re not doing you any favors. In fact, they might be the reason you feel sluggish, bloated, or just plain off.
Today, we’re diving into what seed oils are, why they’re bad news, and which fats you should be using instead. Buckle up—it’s about to get real.
What Are Seed Oils, and Why Are They Everywhere?
Seed oils are extracted from—you guessed it—seeds. But don’t picture a gentle, hand-pressed process. No, these oils are ripped from their seeds using extreme heat, chemical solvents (hello, hexane!), and industrial refining. The end product is an oil so processed that even your grandmother wouldn’t recognize it as food. The usual suspects include:
- Soybean oil
- Corn oil
- Canola oil (rapeseed oil)
- Sunflower oil
- Safflower oil
- Cottonseed oil
- Grapeseed oil
These oils are in everything—salad dressings, chips, cookies, most restaurant food, the majority of processed foods and even “healthy” prepackaged foods. Sneaky, right?
Why You Should Show Seed Oils the Exit
1. They Fuel Inflammation Like a Bad Tinder Date
Omega-6 fatty acids aren’t inherently evil, but seed oils contain them in crazy amounts. Your body needs a healthy balance of omega-6 to omega-3s, but thanks to seed oils, most people are drowning in omega-6s. The result? Chronic inflammation—aka the root of just about every modern disease, from heart disease to diabetes to joint pain.
2. They’re Processed to Oblivion
Seed oils don’t just magically appear in a bottle. They’re refined, bleached, and deodorized—yep, they have to REMOVE the nasty smells so people will actually eat them. During this high-heat processing, the oils become oxidized, meaning they produce free radicals that damage your cells. Think of it as cellular vandalism. Not cute.
3. They Contribute to Chronic Disease—Big Time
Overconsumption of seed oils has been linked to:
- Heart disease
- Obesity
- Metabolic disorders
- Cognitive decline (brain fog, anyone?)
- Gut issues
And here’s the kicker: when these oils are heated (like in frying), they break down even further, producing toxic byproducts like aldehydes, which have been linked to—you guessed it—cancer.
4. They Mess With Your Hormones
If you’re dealing with stubborn weight gain, mood swings, or hormonal chaos, seed oils might be the culprit. They can throw off your body’s delicate hormone balance, affecting everything from estrogen levels to thyroid function. No thanks!

The Fats You Should Be Cooking With Instead
Let’s talk about the VIPs of healthy cooking fats:
- Grass-Fed Tallow – The OG cooking fat. Stable, nutrient-rich, and amazing for high-heat cooking.
- Ghee – Clarified butter with a rich, nutty flavor and loaded with vitamins A, D, E, and K.
- Butter – Real butter, preferably grass-fed, is a delicious and nutrient-dense option for sautéing and baking.
- Coconut Oil – Packed with metabolism-boosting MCTs and perfect for cooking and baking.
- Extra Virgin Olive Oil – A powerhouse of antioxidants and monounsaturated fats. Great for low-heat cooking and dressings.
- Avocado Oil – Higher smoke point, smooth versatile taste, and full of heart-healthy fats.
Final Thoughts: Break Up With Seed Oils (For Good!)
Seed oils might be everywhere, but you don’t have to let them sabotage your health. By switching to real, stable fats like tallow, ghee, butter, coconut oil, extra virgin olive oil, and avocado oil, you’ll fuel your body with what it actually needs—and dodge the inflammation bullet.
Your body deserves better than heavily processed, inflammation-triggering oils. So go on, kick those seed oils to the curb and cook like your ancestors did—with real, nourishing fats. Your taste buds (and your health) will thank you!
