This post is part 2 of a series on dietary fat. Read the first part HERE to see the role fatty acids play in proper cellular function and health.

Now for the bad news: we’ve been eating fake fat for decades, and it took a brutal toll on our collective health. How did we go from butter and lard-eating homesteaders to “shelf stable” vegetable oil consumers?

It all started with one little company that sold soap.  Would you believe it if I told you the company responsible for the distribution of Ivory, Pampers, and Gillette was also responsible for the biggest dietary shift in our nation’s history?

Demise of Butter & Lard

Never was a story of more woe than this of butter, lard, and Crisco.Click To Tweet

Before 1900, the American cooking staples were butter and lard. No one was processing vegetable oils yet and shelf-stable food didn’t exist unless it was salted and cured. In 1907, a German chemist named Edwin Kayser wrote a letter to a popular soap and candle-making company (at the time): Proctor & Gamble.  The chemist wrote to them about a new process where hydrogen could be used to convert the surplus of toxic byproduct used in soap-making–cottonseed oil–into solid, shelf stable fat. (1)

Hydrogenation

Knowing the molecular structure of fat is important to understanding the process of hydrogenation. An unsaturated fatty acid chain is made up of carbon atoms stuck together by two bonds. Hydrogenation involves ripping one of these bonds apart on each carbon atom. The result is a chain of carbon atoms, wherein each atom is also bound to a hydrogen molecule.

Partially hydrogenated fats are considered “in transition” or trans fats because some double carbon bonds remain intact. Fully hydrogenated fat is called saturated fat because the carbon chain is so saturated with hydrogen molecules, it can’t take anymore. (2) Saturated fats occur in abundance in many of our food sources–trans fats do not.

Hydrogenation enabled Proctor & Gamble to turn a red, cloudy, bitter by-product of cotton into a pearly white shelf stable “food” item that looked remarkably like lard: Crisco.

Learn about the rise of fake fat in this 2-part series on dietary fat and how we got it dead wrong for decades.

Crisco

P&G hired America’s first full-service advertising agency to market this new artificial fat. With bizarrely vague slogans like “It’s digestible!” Crisco became the “lighter, healthier” alternative to lard and butter. By 1912, P&G was selling 60 million pounds of Crisco per year. As many or more households were making the permanent switch from saturated fat-filled lard and butter to trans fat-filled Crisco. (1)

Rise of Heart Disease

In 1912, heart disease was uncommon. Pneumonia was actually the leading cause of death up until the 1930’s. With the rise of vaccines and antibiotics, people were starting to live longer and, consequently, die from other things. But, of all the age-related diseases, why did heart disease become the number one killer?

You can guess where I’m going with this: dietary changes. More specifically, the transition from lard and butter to fake vegetable oil, trans fats, and shelf stable corn, grain, and soy products. The availability of these oils rose exponentially in the mid-1900’s. Yet the simultaneous rise of heart disease was attributed to the total opposite thing: saturated fat (which people had started to reduce). How did that happen? (3)

Follow the Money

By the 1940’s, cardiologists began to show concern for the rise of heart disease in the United States. A number of small-scale research groups existed, including a mostly New York-based organization called the American Heart Association. Ever heard of it?

Of course you have. That’s because Proctor & Gamble  gave $1.5 million to this tiny organization in the 1940’s. This display of selfless philanthropy allowed the organization to launch national fundraising campaigns to fund research studies on…dietary fat. (5)

Lipid Research

Several studies into dietary fat popped up in the 1950’s, many of them sponsored in part by the American Heart Association. Among the most (in)famous of these were:

Framingham Heart Study
A long-term (still ongoing) study of an initial 5209 adult subjects in Framingham, Massachusetts, looking into various lifestyle factors and links to heart disease. (7)

Seven Countries Study
A scientist named Ancel Keys looked at the diet of only seven countries, and concluded that high intake of dietary cholesterol is associated with heart disease. (6)

Dietary Guidelines

In 1957, as a response to the findings in the Lipid Research Clinics, The American Heart Association published it’s first ever, laughably non-specific, set of dietary guidelines to the American public:

  1. Diet may play an important role in the pathogenesis of atherosclerosis.
  2. The fat content and total calories in the diet are probably important factors.
  3. The ratio between saturated and unsaturated fat may be the basic determinant.
  4. A wide variety of other factors besides fat, both dietary and non-dietary, may be important.

 

Four years later, the guidelines looked like this:

  1. Maintain a correct body weight.
  2. Engage in moderate exercise, e.g., walking to aid in weight reduction.
  3. Reduce intake of total fat, saturated fat, and cholesterol. Increase intake of polyunsaturated fat.
  4. Men with a strong family history of atherosclerosis should pay particular attention to diet modification.
  5. Dietary changes should be carried out under medical supervision.

 

Suddenly, the dietary guidelines to the public were very specific. None of the studies from the time had found definitive evidence that saturated fat and cholesterol were the cause of rising heart disease, yet the AHA made a nationwide recommendation to increase polyunsaturated fat. Why?

A dietary fat war has been waging now for several decades. On one side are the makers of liquid and partially hydrogenated vegetable oils (i.e. Proctor & Gamble). On the other side are makers (and breeders) of foods containing saturated fat–mainly, the meat and dairy industry. On neutral territory are growers of nuts, avocados, and olives, because…well, they want nothing to do with this “low fat” craze. Let’s take a look at some of the key players and their arguments:

Dr. Fred Mattson

A chemist for Proctor & Gamble, he conducted and presented many studies throughout his career to prove that trans fats (like Crisco) were not harmful to human health. He is credited with influencing the American Heart Association’s 1961 dietary guidelines to the public to increase intake of polyunsaturated fats (vegetable oils) and drastically reduce animal fat and saturated fat. (9)

J. Edward Hunter

He used many of Mattson’s studies and analyses to work on behalf of the Institute of Shortening and Edible Oils. He vehemently discredited and opposed contradictory research and analysis regarding trans fat and vegetable oils.

University of Maryland Graduate Students

The shortening and vegetable oil industries essentially went uncontested until the 1980’s, when a lowly group of graduate students discovered that:

  • many fatty acid profiles on record for various oils were significantly incorrect
  • artificial trans fats were not included as a separate category in any dietary recommendations or analyses

Their realization marks the turning point of the fat wars. They re-analyzed many of Dr. Fred Mattson’s studies and found quite a different picture than what was earlier presented:

1. Those who took a cholesterol-lowering drug in a 1972 study experienced a significant increase in deaths from cancer, stroke, violence, and suicide, compared to those who took a placebo (suggesting that cholesterol plays an important role in mood). (8)

2. A feeding trial in pigs fed a diet of trans fat and polyunsaturated fats led to high parameters for heart disease, compared to pigs fed only saturated fats. (8)

3. The NHLBI Multiple Risk Factor intervention trial found no significant difference in deaths from coronary heart disease between those with low cholesterol and those with high cholesterol. However, deaths from all causes were substantially greater for men with cholesterol levels below 160 mg/dL. (8)

4. Dr. Willian Castelli, the director of the Framingham study, which by the 1980’s had been running for 40 years, said this:

In Framingham, Masachusetts, the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower people’s serum cholesterol. . . we found that the people who ate the most cholesterol, ate the most saturated fat, ate the most calories weighed the least and were the most physically active.” (8)

 

Polyunsaturated Vegetable Oils

It’s been over 60 years since the American Heart Association first gave dietary recommendations to the public. Despite a horrific rise in metabolic disease and chronic health conditions, the guidelines remain much the same:

  • eat low fat dairy products
  • consume skinless poultry and non-fried fish
  • eat whole grains, fruits, and vegetables
  • opt for non-tropical vegetable oils (canola, soybean, corn)

Despite study after study of evidence to the contrary, saturated fat remains the enemy. The recommendation to increase intake of polyunsaturated fat remains. There is still no mention of an optimal omega-3 to omega-6 ratio. Indeed, the levels at which Americans consume omega-6 rich unsaturated vegetable oils has been linked to the following in animal studies: (8)

  • damage to the reproductive organs and lungs
  • inhibited ability to learn under stress
  • liver toxicity
  • compromised immune system
  • depression of mental and physical growth in infants
  • abnormal fatty acid profiles in adipose tissue
  • mental decline and chromosomal damage
  • accelerated aging
  • cancer, heart disease, and weight gain
  • interference with production of prostaglandins
  • clogged arteries

To think that we are somehow different from other animals and that polyunsaturated vegetable oils are actually healthy for us is…ludicrous. Yet they continue their reign in the standard American diet. (11)

Demise of Trans Fat

In the 1990’s, the former graduate students contested the amount of trans fat being reported in packaged foods. Despite the industry’s argument that the average American probably only ate 6-8 grams of trans fat per day, the reality, in looking at the diet of American teenagers, was much higher.

In 2001, P&G conceded and sold the product that started it all–Crisco. Countries around the world began regulating the amount of trans fats that could be used in restaurants and packaged foods. States, counties, cities, and whole states instituted trans fat bans. Many fast food restaurants willingly stopped using them. (10)

Now that artificial trans fats were gone, the public could rest easy that we would make a nationwide return to traditional saturated animal fats and saturated tropical vegetable oils…ha, just kidding.

Rise of Genetically Modified Vegetable Oils

Enter: genetically modified soybeans, capable of producing shelf stable oils like trans fats. In order to be shelf and heat stable, an oil must be low in linolenic (omega-3) acid and high in oleic (omega-9) acid. Scientists genetically modified soybeans to produce an oil that fits the bill. (10)

OK, so GMO’s are not ideal, but we’re safe with non-GMO, expeller-pressed vegetable oils, right?

Unfortunately not, because similar results can be produced with selective breeding. Sunflowers are now selectively bred to produce an oil that is just as low in linolenic acid as its GMO soybean counterpart. Nearly every bean or flower bred for oil is bred to be shelf and heat stable. Therefore, the content of omega-6 polyunsaturated fat is dangerously higher.

When Will it End

As long as companies are making money in a shelf-stable oil and food industry, I cannot imagine this industry-perpetuated fear of saturated fat will ever die. Meanwhile, the government and industry-backed non-profits continue to give dietary guidelines that are making us collectively sicker than we’ve ever been. Sure, we’re living longer, but at what cost? What neurological deficiencies are we enduring because we chemically altered our fat? What metabolic diseases have we propagated by replacing our essential fats with whole grains, fatless protein, and fruits?

    Autumn,
    Really interesting article! I enjoy everything on your site, but this article made me realize: you should write a book! I will place the first pre-order!
    One question- so how does Avacado oil and olive oil stay “liquid” and stable at room temperature? Thanks so much for everything on your site. I’m 1 week (today!) into lectin-free eating and you are such a great resource!

      Hi Sarah, thank you so much for your encouragement 🙂 Avocado oil stays liquid at room temperature because it’s mostly monounsaturated fat, which doesn’t “pack” together like the molecular structure of saturated fat.

    Well written and well researched article. I wish more people had access to this article as it is very informative. I agree with Sarah about writing a book. You write well. I will be second to pre-order. I also love your recipes. Haven’t started the PP way of eating. Just purchased the book. The PP diet resonates well with me. Thank you for creating this online source for anyone wanting to go “lectin-free.”

    Great articles, both parts one and two. I am about four weeks into Plant Paradox eating and even though I am not doing it to lose weight I have lost about 14 pounds. I have bookmarked your site and appreciate all the excellent information you provide. It will take me a while to get proficient with this way of eating but I am glad to read all of the research behind it because that helps me to stick with it. Thank you, Autumn!
