Seed oils are toxic. They cause inflammation. They're driving the obesity epidemic. One prominent voice called them "worse than glyphosate, herbicides, and pesticides combined." In response, fast food chains switched to beef tallow, food companies started reformulating, and people across North America threw out their canola oil.

But is any of this based on evidence?

In this episode, Coach Chris Cooper breaks down the seed oil controversy from the ground up — what seed oils actually are, where the fear came from, and what the research actually shows.

The science is consistent and substantial. A 2019 study tracking over 68,000 people across 13 countries found that higher blood levels of linoleic acid — the primary fat in seed oils — were associated with lower rates of cardiovascular disease and stroke. A 2025 study of nearly 1,900 people found higher linoleic acid linked to lower inflammation markers. A peer-reviewed 2026 paper in Nutrition Today concluded clearly: linoleic acid does not promote inflammation or oxidative stress.

The anti-seed-oil movement has correctly identified a real health problem — ultraprocessed food. They've just pointed at the wrong culprit. The oil isn't what's making those foods harmful.

You'll learn what's actually worth worrying about, why the omega-3 to omega-6 conversation matters but isn't solved by avoiding canola oil, and three evidence-based steps that address the real issue.

Don't let a well-marketed panic distract you from what actually matters.
