The Fry Lie: How McDonald’s Fries Got Worse—Not Healthier
McDonald’s fries lost their flavor in the '90s—thanks to a food activist, not science. The new "healthier" oil? It was worse. Here's the crispy truth.
Once upon a time, McDonald’s fries were unbeatable. Golden. Crispy. Perfect. People swore they were the best fries ever made. And honestly? They were.
But then something changed.
In the 1990s, fans noticed the fries didn’t taste the same anymore. They were still golden, still crispy, but the rich, beefy flavor? Gone. So what happened?
Let’s break it down—because the reason has more to do with a millionaire food activist than any actual science.
The Original Secret: Beef Tallow
Before 1990, McDonald’s cooked their fries in a mix of 7% cottonseed oil and 93% beef tallow (aka rendered animal fat). This gave them a rich, savory flavor and crispy texture that people still miss.
Ray Kroc, the man behind the McDonald’s empire, insisted on this formula because it recreated the fries from the original McDonald brothers. And it worked—for decades.
The Activist Who Changed the Fry Game
Then came Phil Sokolof—a millionaire businessman who had a heart attack and decided to launch a one-man war against saturated fat.
He wasn’t a doctor. He wasn’t a nutritionist. But with deep pockets and lots of passion, he took out full-page ads in major newspapers warning America about fat. One headline read:
“The Poisoning of America”
It worked. In 1990, McDonald’s replaced beef tallow with 100% vegetable oil to protect its public image.
Trans Fats: The Real Villain
The new oil may have seemed like a healthier option. But here’s the twist: it wasn’t. McDonald’s used partially hydrogenated vegetable oil—a.k.a. trans fats.
Trans fats raise bad cholesterol (LDL), lower good cholesterol (HDL), and increase your risk of heart disease. In fact, they’re even worse than the saturated fat Sokolof was trying to ban.
Trans fats weren’t banned in the U.S. until 2018. That means for nearly 20 years, McDonald’s “healthier” fries were actually worse for your heart than the original recipe.
Flavor Fail: The “Natural Beef Flavor” Cover-Up
When customers noticed the fries didn’t taste the same, McDonald’s responded by adding “natural beef flavoring” to the vegetable oil.
Yes—after removing beef fat, they added beef flavor back in. That move confused vegetarians, angered Hindus, and even led to lawsuits. Today, McDonald’s fries in the U.S. are still not vegan—but in the U.K., they are.
Steak 'n Shake, RFK Jr., and the Comeback of Bad Ideas
Recently, Steak 'n Shake announced they were returning to beef tallow for frying. And who celebrated this move?
RFK Jr., a political figure turned food commentator—with no medical training and no background in nutrition. He’s never taken a college-level science course. But that didn’t stop him from endorsing the return of beef fat.
Let’s be clear: Beef tallow isn’t healthy. It’s high in saturated fat and cholesterol. It might taste nostalgic, but it’s no better for your heart.
The Real Takeaway
This isn’t just about fries.
This is about how non-experts keep shaping public health decisions—with loud voices, big headlines, and zero science.
It’s about how we chased the illusion of “healthier” food and ended up with trans fat-laced fries that tasted worse and harmed more people.
And it’s a reminder: if someone wants to change your food, check their credentials first.

Never eat McDonalds,period. Well actually no fast food at all. Too many calries and does not taste particularly good.
