The thing that replaced real fat in your kitchen was never food.

I want to tell you about the villain in my own story.

In the other things I've written here, I told you about the parking lot, the lab report, the triglycerides at 642, and the conversation with my doctor that I can't stop thinking about. I told you that real fat was never the enemy. The enemy was always what replaced it.

But I never told you exactly what that replacement was. So let me say it plainly, the way I'd say it to you at my own table.

It's the oil in your kitchen right now. The yellow bottle of "vegetable oil." The canola, the soybean, the corn, the sunflower, the safflower. The stuff that's in almost everything that comes in a box, a bag, or a wrapper. We call them seed oils. And the more I learned about where they actually come from, the more my stomach turned.

It started as something nobody wanted

Here's the part that got me.

Around 1900, cottonseed oil had a bad reputation. It was associated with soap, candles, dyes, and roofing tar, not with food. It was the leftover of the cotton industry, and at one point cheap cottonseed oil was even used to secretly cut and stretch olive oil.

Then Procter & Gamble, a soap company, figured out they could chemically harden that cottonseed oil into something white and creamy that looked a lot like lard. In 1911 they put it on the market and called it Crisco. The name itself is short for "crystallized cottonseed oil," but they deliberately avoided telling people what was actually in it, because the ingredient had that bad reputation. They handed out free cookbooks where every recipe used it. Sales hit 2.6 million pounds in its first full year and 60 million pounds by 1916.

That was the beginning. Soybean, corn, canola, and the rest followed. A thing that was industrial waste became the fat in the American kitchen in about three generations.

I'm not telling you this to scare you. I'm telling you because for most of my life I had no idea. I bought the bottle. I thought I was being healthy. I cooked my kids' food in it.

How it's actually made

I always assumed oil was pressed. You squeeze the fruit, oil comes out. That's how olive oil works, and I know that one well, because years ago I built an olive oil company. I spent real time around good oil, the kind that comes from pressing the fruit and nothing else, and I learned what an honest oil actually is. You can smell it. You can taste the place it came from. There's a nobility to it that you don't have to explain to anyone who has tried it.

So when I tell you most of the oil on the shelf isn't made that way, it isn't a guess. It's coming from someone who knows what the honest version looks like.

Because that's not how most of these are made.

To get oil out of a soybean or a kernel of corn, pressing isn't enough. There's too little oil and it's locked inside the seed. So the seeds are cracked, cooked, flaked, and then washed in a chemical solvent that dissolves the oil out. The solvent used almost everywhere in the industry is called hexane. Hexane is a petroleum product. It's the same family of chemicals used in paint thinners and industrial cleaners.

I'm not saying you're drinking paint thinner. The processors heat the oil afterward to boil the hexane back off and reuse it, and what's left in the final oil are trace amounts that regulators allow. That's all true and I want to be fair about it.

But here's what I couldn't get past once I understood it. My grandmother's fat came from a cow or a churn. This oil comes out of a factory that needs a petroleum solvent, high heat, and several rounds of chemical refining just to make the result smell like nothing and look clear enough to sell. One of those is food. The other is a manufacturing process that happens to end in a bottle on a shelf.

The number that stayed with me

There's a study published in the American Journal of Clinical Nutrition back in 2011. Researchers reconstructed what Americans actually ate, fat by fat, from 1909 all the way to 1999.

What they found is that the main fat in seed oils went from under 3% of our calories to over 7%, and that per-person soybean oil consumption rose more than a thousand times over that same stretch. As those oils climbed, the old fats, tallow, butter, and lard, fell almost exactly in step, like one was pushing the other out of the kitchen.

That's not a small change in seasoning. That's a complete rebuild of what an entire country eats, done quietly, in about a hundred years, while everyone was being told it was the healthy choice.

I keep coming back to the same question I asked myself in that parking lot. If we got it this wrong, this completely, for this long, who was it actually serving? Because it wasn't serving me. I followed every rule and still ended up in a cardiologist's office.

I'm not a doctor. Here's what I did.

You know by now that I'm not a scientist and I'm not going to pretend the science is fully settled, because it isn't, and people argue about it.

So I'll only tell you what I did. I took the seed oils out of my kitchen. All of them. I went back to the fats my great-grandmother would have recognized on sight. Real grass-fed ghee for the everyday cooking, and beef tallow for the high heat, the searing, the things that need to get crispy.

My triglycerides went from 642 to 108. My cholesterol ratio went from 7.7 to 4.5. No medication. I've told you that before, and I'll keep telling you, because it's the only proof I have and it's mine.

Here's the simplest way I can put it. You don't need to understand the chemistry. You just need to ask one question when you pick up a fat. Would my great-grandmother recognize this as food?

A jar of ghee, yes. A block of tallow, yes. A clear bottle of oil that needed a petroleum solvent and a factory to exist, I'll let you answer that one.

That question is the entire reason Fatly Good exists. Two real fats. Nothing hidden. No seed oils. The way kitchens worked before someone decided that waste could be sold as health.

Fat never felt so right.
