The Alzheimer’s myth that’s finally crumbling

Why am I not surprised that yet another medical myth is being shattered?

It’s not like I didn’t already suspect the truth—I just didn’t have any solid evidence until now.

So, let’s talk Alzheimer’s disease (AD).

For years, scientists have blamed tau protein tangles in the brain for this dreaded diagnosis.

But new research reveals a different story—one that could completely change our understanding of AD.

Toxic fat buildup

According to a recent study, tau proteins play a critical role in regulating fat metabolism in the brain. But when these proteins become dysfunctional, they may contribute to AD by allowing toxic fats to accumulate.

This suggests it’s not the presence of tau proteins that creates a problem—it’s their dysfunction.

Sound familiar? The same mainstream myth has run rampant with cholesterol and heart disease…

Cholesterol has long been blamed for heart attacks, even though it doesn’t cause cardiovascular disease. The real danger is when cholesterol becomes oxidized, contributing to inflammation and arterial damage.

But instead of addressing this root cause, mainstream medicine has declared war on cholesterol—triggering an epidemic of unnecessary statin prescriptions. (Learn about the dangers of statins by clicking here.)

In fact, I wouldn’t be surprised if our aggressive cholesterol-lowering campaigns are fueling the Alzheimer’s epidemic, too!

After all, we’ve been looking at the disease all wrong…

It’s not a protein problem

When it comes to neurodegeneration (like AD), the pendulum is finally swinging toward fat metabolism, rather than tau protein tangles, as the root cause.

And this makes sense—after all, our brains are 80 percent fat.

Plus, new research shows that tau proteins don’t just sit around forming harmful tangles—they help regulate lipid metabolism.

See, tau interacts with fat in our neurons (brain cells) and helps transfer them to astrocytes (the brain’s support cells). Astrocytes then remove harmful oxidized lipids before they cause damage to the brain. It’s a crucial protective function.

Even more surprising? Tau helps clear our peroxidized (damaged) fats from neurons—acting as the brain’s natural detox system, much like cholesterol in blood vessels.

So, when tau proteins become dysfunctional, fat accumulation can overwhelm the system—leading to disease.

This is incredible insight—and I’m eager to see more research focused on the impact tau has in our bodies (not just on how it looks).

Bottom line? Our bodies have powerful self-protective mechanisms. Yet, Big Pharma sabotages these processes by pushing unnecessary pharmaceutical “treatments” that don’t even target the real culprit of disease.

I think it’s high time we take a step back and rethink everything we thought we knew about this dreaded brain disease.
