(And How Seed Oils Quietly Wreck Your Heart)
For years, we’ve been told the same tired story:
High cholesterol causes heart disease.
Eat low-fat. Avoid red meat. Swap butter for margarine. And whatever you do—fear the egg yolk.
But what if that story is dead wrong?
What if cholesterol isn’t the villain—but actually a vital repair tool your body uses when something is already going wrong?
And what if the real issue behind heart disease isn’t cholesterol at all… but inflammation—especially the kind fueled by seed oils?
Let’s break it down.
What Cholesterol Actually Does in Your Body
Cholesterol is not a toxin.
It’s not sludge.
It’s not something you “flush out.”
It’s a critical substance your body uses to:
- Build cell membranes
- Create hormones (like testosterone, estrogen, and cortisol)
- Produce vitamin D
- Repair tissue damage and fight inflammation
In other words: if you didn’t have cholesterol, you’d be dead.
So why did we start blaming it for heart disease?
The Flawed Theory That Started It All
In the 1950s, a scientist named Ancel Keys published the “Seven Countries Study.” He claimed that countries with high saturated fat intake had more heart disease—and that cholesterol was to blame.
But here’s the catch:
He ignored data from countries that didn’t fit his theory (like France, where people eat tons of fat but have low heart disease). And his methods were deeply flawed.
Still, it was enough to launch a decades-long war against fat and cholesterol.
Governments ran with it.
Doctors repeated it.
Food companies capitalized on it.
And we all started eating low-fat, high-carb diets full of processed seed oils.
The Real Problem? Chronic Inflammation
Heart disease starts with damage to your arteries.
Tiny cracks. Microtears. Oxidative stress.
Cholesterol shows up to fix the damage, kind of like firefighters responding to a blaze.
But instead of asking why the fire started, mainstream medicine blames the firefighters.
That’s backwards.
The real question is: what caused the damage in the first place?
Answer: inflammation—and one of the biggest, most overlooked sources is what you’re cooking with every day.
How Seed Oils Fuel the Fire
Let’s talk canola, soybean, corn, sunflower, safflower, and grapeseed oils.
These oils:
- Are packed with omega-6 polyunsaturated fats (PUFAs)
- Contain linoleic acid, which oxidizes easily inside your body
- Generate toxic byproducts like aldehydes when heated
- Are hidden in almost every packaged food on the shelf
- Stay in your fat tissue for over 600 days
This isn’t a small problem—it’s everywhere. And over time, these oils:
- Damage your cells
- Trigger immune responses
- Inflame your arterial walls
- Set the stage for plaque buildup, blood clots, and insulin resistance
The result? More heart disease. Not less.
What the Science Says (That No One’s Talking About)
- Cholesterol doesn’t clog arteries unless it’s oxidized
- Oxidized LDL (not total LDL) is what’s linked to heart disease
- Seed oils increase LDL oxidation
- Saturated fat? It’s actually protective and raises HDL (the “good” cholesterol)
The real heart risk isn’t from eating butter. It’s from cooking with canola oil and eating ultra-processed junk masquerading as health food.
What to Do Instead
Stop fearing cholesterol—and start focusing on inflammation.
Here’s how to protect your heart and your hormones:
- Ditch seed oils (check labels—even “organic” snacks use them)
- Cook with tallow, ghee, duck fat, butter, or coconut oil
- Eat pastured eggs, grass-fed meat, and wild-caught fish
- Prioritize raw dairy and mineral-rich salt
- Focus on sleep, movement, sun, and stress management
And if your doctor’s panicking about your cholesterol, ask them:
“Do you test for LDL particle size, triglyceride/HDL ratio, or inflammation markers like CRP?”
Because those are the real predictors—not your total cholesterol score.
You’re Not Broken—You’re Just Misled
The war on cholesterol was never based on real science. It was based on fear, flawed studies, and food industry agendas.
The truth is, cholesterol is a lifeline, not a threat.
And the sooner we shift focus toward inflammation, oxidative stress, and metabolic dysfunction, the healthier we’ll all be.
