Fast Break is a CPGSPN spinoff where I transition from cold emails and power rankings to the CPG stories that matter most to me.

Today’s subject: The Food Pyramid

For decades, America has been told how to eat by the government.

Grains at the base, fats at the top, the impact of sugar barely mentioned at all. Schools taught it. Brands built around it. Families were guided by it. And we trusted it, because it came stamped with the authority of Harvard scientists, USDA insiders, and the most respected public health institutions in the country.

But there’s an interview behind our dietary guidelines that most people have never seen. An interview that had never been published. Until this week.

➡️ Let’s dive in.

It begins in a nursing home in 2005, where Dr. Mark Hegsted, one of the architects of the U.S. dietary guidelines, spent his final years reflecting on his contribution to the nutritional advice that shaped generations.

An interview was recorded by Emily Kaplan and left untouched for over two decades. A deathbed-style confession that complicates the origin story of modern nutritional guidance.

➡️ But first, who was Dr. Mark Hegsted?

In terms of nutrition and dietary policy, Dr. Mark Hegsted wasn’t a bench player. He wasn’t even a role player. In the literal sense of it, he was a superstar at the center of American nutrition for more than fifty years.

Born in Idaho in 1914, he earned a PhD in biochemistry and ended up at Harvard’s School of Public Health in the early 1940s. By the 1960s, he was conducting studies and publishing what became known as the Hegsted Equation. This equation argued that saturated fats raised cholesterol levels, monounsaturated fats had little to no effect, and polyunsaturated fats lowered cholesterol levels. The research resonated and helped push the country toward a low fat, high carb way of eating.

This body of work eventually pulled him out of the lab and into DC. Hegsted helped draft the original 1977 Dietary Goals, which became the Dietary Guidelines that have shaped federal advice ever since. Well, I guess up until the MAHA movement of today.

In 1978, he led nutrition programs at the USDA, and in 1982, he was hired by Harvard Medical School, all the while publishing hundreds of papers and advising every major health agency you can name.

➡️ For decades, America was guided by a nutrition story he helped write. This influence is important to note for later in this article.

At the time of the interview, Emily reported for the Las Vegas Review-Journal and freelanced at Jane Magazine, where she focused on stories involving unethical practices by doctors…including this one.

She then moved on to ABC, where this story stayed on the back burner until this week.

Since then, Emily has had a decorated career spanning stints at The Boston Globe, Boston Magazine, and CrossFit.

Today, she is the CEO of The Broken Science Initiative and Principal at The Kleio Group, a PR firm that focuses on strategic communications.

➡️ Let’s take a look at the history of America’s dietary guidelines from 1916 to present day.

Here is the arc of America’s nutrition advice over the last century.

Emphasized fruits, veggies, and milk as “protective” against nutritional deficiencies. Fats and sugars were deemed necessary for energy in moderation. Measurements used were cups, spoons, and weight.

  1. Milk and Meat

  2. Cereals and Starchy Foods

  3. Fruits & Vegetables

  4. Fats & Fatty Foods

  5. Sugar & Sugary Foods

Everything about this era was about cost-to-nutrient efficiency and the absolute minimum nutrition needed for survival at the lowest possible cost.

  1. Milk

  2. Potatoes and Sweet Potatoes

  3. Dry Beans, Peas, and Nuts

  4. Tomatoes and Citrus Fruits

  5. Leafy Green and Yellow Vegetables

  6. Other Fruits & Vegetables

  7. Eggs

  8. Lean Meat, Poultry, and Fish

  9. Flours & Cereals (including cornmeal & macaroni)

  10. Butter

  11. Other Fats (including oils & lard)

  12. Sugars (including molasses & syrups)

The number of food groups changed from 5 to 12 and then back to 7.

  1. Leafy Green & Yellow Vegetables

  2. Citrus Fruit, Tomatoes, and Raw Cabbage

  3. Potatoes and Other Fruits & Vegetables

  4. Milk, Cheese, Ice Cream

  5. Meat, Poultry, Fish, Eggs, Dried Peas, Beans

  6. Bread, Flour, Cereals (whole grain, enriched, or restored)

  7. Butter & Fortified Margarine

You guessed it. We’re moving the major food groups again. This time 4.

  1. Milk

  2. Fruit & Vegetable

  3. Meat

  4. Bread & Cereal

This is the first guide that was created after Dr. Mark Hegsted’s contribution to The 1977 Dietary Goals for the United States. This is where they added a 5th group that targeted fats, sweets, and alcohol.

  5. Fat, Sweets, & Alcohol (CAUTION)

The first time servings are suggested. Coincidentally, the same timeframe that High Fructose Corn Syrup hit mainstream and the obesity epidemic began.

The pyramid that all 90s kids remember. The one that was likely even printed on the actual packaging of the food you bought!

I have absolutely no recollection of this one. Zero. Zilch.

A beautiful step in the right direction.

➡️ And here’s where the whole story flips.

During that interview, Hegsted admitted he wished he had done two things differently.

Namely, the “eat less fat” guidance had two side effects:

  • Americans reduced meat consumption

  • And they were never told to reduce refined flour and sugar

⬇️ It can be argued that Dr. Mark Hegsted’s research, guidance, and stances over the years are, in large part, attributable to the American metabolic health epidemic that we face today. This serves as a stark reminder. Sometimes “trust the science” means trusting the doctors who accepted the cash.

And that has always been a losing proposition.

America didn’t choose a high carb diet. A handful of men chose it for us.

Dr. Mark Hegsted is one of the three Harvard scientists bribed by the sugar industry, through the Sugar Research Foundation, who wrote a piece in the prestigious New England Journal of Medicine stating that fat, not sugar, was the cause of coronary heart disease.

This conspiracy was uncovered in Harvard’s basement (literally) in 2016 by Dr. Cristin Kearns after decades of being concealed. She found that Dr. Hegsted and Dr. Robert McGandy, under the purview of Dr. Frederick Stare, were paid the equivalent of over $50k in today’s dollars to discredit studies that implicated sugar as the reason behind coronary heart disease.

“Kearns said the papers, which the trade group later cited in pamphlets provided to policymakers, aided the industry’s plan to increase sugar’s market share by convincing Americans to eat a low-fat diet.” - Melissa Bailey

We traded fat for sugar, whole foods for starch, and we are paying for it in real time. Nearly half of America is diabetic or pre-diabetic. Over 100 million Americans are pre-diabetic, and most have no idea.

As the government rewrites the pyramid again, we need to ask who has our best interests at heart and who is getting paid to sell us out?

Right now, there’s promise. An emphasis on protein, dairy, healthy fats, fruits & vegetables, and the reduction of highly processed, refined carbs that have previously been coined “empty calories.”

To the refined sugar apologists out there…cane sugar is not the hero ingredient you think it is. And stevia and monkfruit are not the enemy you make them out to be.

Cane sugar had its half-century at the top. It can sit the next one out.
