Coming up on today's show.

What I'm interested in is what made everybody get fat over the last, call it, 100 or so years.

Why did we go from the fat lady in the circus to 77% of Americans are overweight or obese?

If you're Robert Kennedy and you get kidnapped by Donald Trump and force-fed French fries on the airplane.

He's going to be fine because he only does that once in a while.

But if you're doing this every day, all of this rancid fat and the ultra-processed foods that

Americans eat every day, you're never getting the off signal.

It's like pouring water in a bathtub where the drain always fill.

Eventually, it's going to fill up and overflow. That's what is causing our obesity epidemic.

I'm the type of guy who I once spent my lunch hour in the salad dressing aisle of whole foods going

through every single bottle. And I found one single bottle out of the whole aisle that was made with olive oil and no seed

oil. There are also two studies that unintentionally compared cigarettes to seed oils. And the cigarette

wing did better than the seed oil wing. Tucker, let's start off having you give a general overview of why seed oils are so toxic.

Let's jump right into things. They're very susceptible to going rancid, right? And rancidity isn't

something that we hear a lot about nowadays, but it used to be a big concern.

Rancid fats are toxic fats.

You want to avoid eating things that are toxic.

And seed oils are of all the fats that we consume, the most likely to go rancid and become toxic.

And the result of that toxicity is, I would argue, why we have this epidemic of chronic disease.

So when we talk about rancidity, making them toxic, where along the processing does that happen?

When they're being manufactured, when they're sitting in storage on the bottle before we buy it or before we use

the product, there's transportation, there's heating usually, or not usually, but sometimes
