A new video from Prager University — this time, who the government made you fat!:
Ever since the introduction of the Food Pyramid in the early ’90s, the average American has gotten fatter and sicker. Has this government-approved nutritional guideline — the basis of the modern “healthy diet” — led us astray? If so, how did this happen, and what can we learn from it? Cardiologist Dr. Bret Scher offers some food for thought on this very weighty issue.
From the transcript:
Here’s a riddle:
How is it that ever since the government began telling us what to eat, we have gotten fatter and sicker?
In 1977, when the government first set dietary guidelines, the average American male weighed 170 pounds. He now weighs 197. It’s not any better for women —145 to 170. And you don’t need an academic study to know the same thing is happening to kids. Just look around.
The weight gain has real-life consequences: the percentage of Americans diagnosed with type 2 diabetes—a condition that can lead to severe medical issues—has risen from 2% in 1977 to over 9% in 2015. In hard numbers, that’s five million people to over 30 million people.
How did this happen?
It all started innocently enough in the 1950s, when President Dwight Eisenhower had a heart attack while in office. Suddenly, the issue of heart health became a national obsession.
Keep in mind this was an era when scientists had harnessed the power of the atom, unlocked the secrets of DNA, and cured once incurable diseases like polio. Surely, there had to be a scientific solution to heart disease.
There was. And a charismatic medical researcher from the University of Minnesota named Ancel Keyes had it.
Cholesterol, Keyes claimed, was the villain of the heart disease story.
His now famous “seven countries study” determined conclusively—in his mind, at least—that people who consumed high amounts of fat—specifically, saturated fat—had higher cholesterol levels and thus, higher rates of heart attacks.
Lower your fat intake, and you would lower heart disease risk.
The ever-confident Keyes spread the gospel. As an influential member of the American Heart Association, he was in a very strong position to do so. There was only one problem: Keyes’s study was bad science. The sample size was so small, the data collection integrity so shoddy, and the life-style variables between the countries he studied so great, that his research had no scientific validity. In other words, he asserted a conclusion he couldn’t prove.
When other scientists questioned Keyes’s conclusions, they were invariably met with stern responses like: “people are dying while you’re quibbling over data points.” And, “there are great benefits and no risks” to adopting this new way of eating.
In 1973, the American Heart Association set the dietary limit on saturated fat at 10%, and in 1977, the US government followed suit. Where did the 10% value come from? It didn’t come from any scientific data. It was merely a government committee’s best guess.
This was despite contrary evidence like the 1957 Western Electric Company employee study showing no difference in heart attacks in those who ate more or less saturated fat. A longer-term study of the same Western Electric subjects in 1981 reached the same conclusion. But again, no one wanted to hear it.
