Is There Really "Antifreeze" in Your Food?
You've seen the meme: propylene glycol is "in antifreeze," and it's also in your cake mix, salad dressing, and ice cream. Technically true — and also one of the most misleading food scares going. Here's the part the meme leaves out.
The traditional, highly toxic antifreeze. A small amount can kill. Not used in food, ever.
Used in "non-toxic"/"pet-safe" antifreeze precisely because it's low-toxicity. Also a food humectant.
The switch the scare ignores
"Antifreeze" isn't one chemical. The dangerous antifreeze is ethylene glycol. Propylene glycol is what manufacturers switched to for "non-toxic" antifreeze — chosen specifically because it's far safer. So "it's in antifreeze" is true in the same way water is in antifreeze: it's the safe ingredient, not the poison.
Propylene glycol is in the safe antifreeze because it's safe — that's the opposite of the implied scare.
What it actually does & the real nuance
- In food — a humectant and carrier for flavors/colors; keeps things moist (cake mixes, dressings, some ice cream).
- Regulatory status — FDA lists it Generally Recognized as Safe; EFSA sets an acceptable daily intake.
- The honest EU note — the EU is stricter: it limits propylene glycol's uses and sets a lower acceptable intake than the US. A real difference, just not an "antifreeze poisoning" one.
- It's still a processing marker — like most additives, it mostly shows up in ultra-processed food. That's the signal worth watching, not the antifreeze meme.
The honest assessment
TrueFood corrects scares as readily as it raises them. The "antifreeze in your food" line is a chemistry sleight-of-hand — it swaps the safe glycol for the deadly one in your head. Propylene glycol at food levels is low-risk; the legitimate note is that the EU regulates it more tightly and it travels with ultra-processed food. Real concern, minus the horror-movie framing.
