Why Seed Oils Might Be Doing More Harm Than Good

By Dr. Philip W. Faler, ND

Seed oil

The issue isn’t just that seed oils are processed—it’s what they do inside your body.

1. Pro-Inflammatory Overload

Seed oils are loaded with omega-6 fatty acids, particularly linoleic acid. While we need some omega-6s, the modern diet floods our system with them—throwing off the healthy omega-6 to omega-3 balance.

This imbalance contributes to chronic inflammation, a key player in:

  • Heart disease
  • Diabetes
  • Obesity
  • Autoimmune conditions
  • Mood disorders

Inflammation isn’t just a buzzword—it’s your body’s emergency signal stuck in the “on” position.

2. Oxidative Stress and Cell Damage

Linoleic acid is highly unstable, especially when exposed to heat (think frying or sautéing). It oxidizes easily, forming harmful compounds like aldehydes and lipid peroxides, which can damage your cells, proteins, and DNA.

Long-term exposure to these oxidized byproducts has been linked to:

  • Accelerated aging
  • Neurodegenerative diseases
  • Increased cancer risk

Not the kind of seasoning you want with your fries.

3. Mitochondrial Dysfunction

Emerging research suggests excess linoleic acid can interfere with your mitochondria—the little engines inside your cells. That means less energy, more fatigue, and metabolic slowdown.

4. Insulin Resistance & Weight Gain

High omega-6 intake has been associated with reduced insulin sensitivity, making it harder for your body to regulate blood sugar. This leads to higher fat storage, especially around the midsection, and increased risk of metabolic syndrome.

🔄 Healthier Alternatives That Actually Nourish You

Let’s replace the bad with the good. Here are some delicious, nutrient-rich alternatives:

  • Extra Virgin Olive Oil – Full of antioxidants and polyphenols. Great for your heart and your taste buds.
  • Avocado Oil – High smoke point, packed with monounsaturated fats.
  • Coconut Oil – Contains medium-chain triglycerides (MCTs) for quick-burning energy.
  • Grass-Fed Butter or Ghee – Full of fat-soluble vitamins like A, D, and K2.
  • Tallow & Lard (from pasture-raised animals) – Stable at high heat and rich in essential fatty acids.

Final Thought: Don’t Fear Fat—Just Be Smart About It

Seed oils are modern inventions, industrially processed and introduced into our food system less than 100 years ago. Our bodies haven’t evolved to handle them well.

So next time you’re in the kitchen or reading a food label, show your body some love—ditch the seed oils and cook with fats your ancestors would recognize.

Your cells, your metabolism, and your future self will thank you.
