What we love to eat may not be what we think it is.
🍟 Introduction
Crispy, salty, oily, and just a bit sweet—French fries are addictive. But is it because we made them at home and loved them? Probably not.
More likely, it’s because fast food giants have spent decades perfecting how fries look, taste, and make us feel. Their marketing is powerful, and their fries are engineered to hit all the right pleasure points. I’ve watched Michael Pollan’s RSA talk, read his book Cooked, and seen the Netflix documentary too—and all of them made me look at this humble snack a little differently.
In Part 1 of this series, we celebrated the history and joy of French fries. But now, it’s time to peel back the layers and examine the systems behind them.

Behind the Golden Arches
The fries we crave from McDonald’s—those long, golden sticks standing tall in the iconic red carton—aren’t just a happy accident. They’re the result of careful engineering, and it starts with the potato.
To get that perfect shape and color, McDonald’s uses the Russet Burbank, a potato variety known for its size, length, and smooth skin. But this potato is vulnerable—especially to a disease called net necrosis, which causes dark spots that make it unusable by fast food standards.
To meet those strict cosmetic requirements, farmers apply large quantities of pesticides, including Monitor (methamidophos), a powerful systemic insecticide. According to Pollan, the chemical is so toxic that farmers can’t even enter the field for several days after spraying.
Once harvested, these potatoes aren’t sent straight to the factory. They’re stored in sealed, football-field-sized sheds with powerful ventilation systems for up to six weeks—just to let the chemicals off-gas.
Only then are the potatoes washed, trimmed, and par-fried in oil before being frozen and shipped around the world. To maintain their signature look and taste, they’re treated with dextrose, citric acid, and dimethylpolysiloxane—a carefully calibrated formula to keep every fry consistent.
19 Ingredients in One Fry?
A McDonald’s French fry contains over a dozen ingredients. It’s not just potato, oil, and salt. It’s an engineered product.
Some common ingredients include:
- Potatoes: The base ingredient, but selected for appearance and size, not just taste.
- Vegetable oil (a blend of canola, soybean, hydrogenated oils): Used for frying; hydrogenation helps with shelf stability but may raise health concerns.
- Dextrose (sugar): Applied to maintain consistent golden color after frying.
- Sodium acid pyrophosphate: Prevents potatoes from turning gray after being cut and frozen.
- Natural beef flavor (contains wheat and milk derivatives): Adds a savory, meaty taste—note, it’s not vegetarian.
- Citric acid: Acts as a preservative to extend shelf life.
- Dimethylpolysiloxane: An anti-foaming agent added to frying oil to reduce splatter and improve consistency.
“If it’s just a fry, why does it need a chemist?”
⚠️ Pollan’s Warning
Pollan’s core message? Cooking is power.
When we stop cooking for ourselves, we hand over control—of our nutrition, our choices, even our cultural values—to corporations. His RSA talk ends with a striking point:
“If you cook, you’re reclaiming your health and your independence.”
This isn’t about guilt. It’s about being aware.

💬 Final Thoughts
We’ve taken a journey—from crunchy delight to a deeper, more complicated truth. This series isn’t about ruining French fries—I still love them too. But now, I see them differently. That small shift—from mindless munching to intentional eating—can change everything.
Sure, homemade fries might not taste exactly like fast food ones. But they’re real, they’re fresh, and they’re free of additives we can’t even pronounce.
This isn’t about being perfect. It’s about being aware. Even something as simple as a French fry can carry a story. And once we know that story, we can’t un-know it.
Knowing is power.
Understanding what goes into our food isn’t about fear—it’s about freedom. It’s about choosing what we eat, rather than letting someone else choose for us.
Choosing for ourselves—even something as small as how we eat our fries—is a quiet kind of resistance. And small steps like that? They’re never really small.
Because when we understand our food, we can enjoy it more honestly, more deeply—and maybe even more deliciously.
