As we meander through the aisles of our local grocery store, it's almost impossible not to notice the multitude of options touting "low fat", "skim", or "fat-free" labels. From milk to cheese, it seems as if the world of dietary fat has been put on a rigorous diet of its own. And when did our morning meal, steeped in a variety of cultural traditions, get replaced by a bowl of packaged cereal swimming in skimmed milk? The shift is so stark, so divergent from our evolutionary and cultural roots, that it borders on the surreal.
But where did this narrative originate? Who cast the first stone, painting fat as the dietary villain? The answer lies in the sprawling corridors of the food industry. Through strategic marketing and pervasive messaging, they've propagated a fear of fat, steering consumers towards their 'healthier' alternatives.
In our journey together, we will unravel this narrative, questioning the status quo and exploring the often misunderstood, yet vital role of fats in our diet and overall gut health. Buckle up as we debunk the myths and shine a light on the truth behind fats!
The Role of the Food Industry in the Vilification of Fat
The vilification of fat can be traced back to the mid-20th century, when the economic interests of the food industry began to shape public opinion on nutrition and health. This era marked a turning point in the understanding of dietary fat, as several influential studies funded by the food industry erroneously linked saturated fat to heart disease, leading to the promotion of low-fat diets as a means to improve public health.
Over the many decades the food industry has funded research that shows fat is the enemy. Below are a few examples of those researches. These are mere examples not the exhaustive list.
1950s:
The Seven Countries Study, led by Ancel Keys, began in the late 1950s and compared the diets and heart disease rates of different populations. This study found a correlation between saturated fat intake and heart disease, although critics argue that Keys cherry-picked data to support his hypothesis.
Ancel Keys, an American physiologist, proposed the diet-heart hypothesis, which suggested that saturated fat and cholesterol were the primary drivers of heart disease. Despite limitations in his research, the hypothesis gained traction and laid the groundwork for the food industry's anti-fat campaigns.
1960s:
The Sugar Research Foundation (now the Sugar Association) funded a series of studies that downplayed the role of sugar in heart disease while emphasizing the alleged risks of saturated fat. These studies helped shape dietary guidelines, pushing the public towards low-fat, high-carbohydrate diets.
1970s:
The Framingham Heart Study, which began in the 1940s and continued through the 1970s, investigated the relationship between various risk factors and heart disease. Some interpretations of the study's results emphasized the association between saturated fat and cholesterol levels, leading to recommendations to reduce saturated fat intake.
The Senate Select Committee on Nutrition and Human Needs, chaired by Senator George McGovern, released the first Dietary Goals for the United States in 1977, which recommended reducing saturated fat intake to lower the risk of heart disease. These guidelines were heavily influenced by food industry-funded research and further solidified the anti-fat narrative.
1980s:
The National Cholesterol Education Program, launched in 1985, promoted the idea that reducing dietary cholesterol and saturated fat could lower blood cholesterol levels and reduce heart disease risk. This program was influenced by food industry-funded research and reinforced the low-fat diet trend.
The food industry capitalized on the low-fat diet trend by developing and marketing a wide range of low-fat, highly processed food products. These products often replaced fat with sugar, refined carbohydrates, and artificial ingredients to maintain taste and texture.
1990s:
The Women's Health Initiative (WHI) was a large-scale study launched in 1991 that investigated the effects of low-fat diets on heart disease, cancer, and other health outcomes. Although the study had mixed results, some researchers and the media emphasized the potential benefits of low-fat diets, further entrenching the anti-fat narrative.
Food companies continued to promote low-fat products and heavily advertised them as healthier alternatives. Brands like SnackWell's became synonymous with the low-fat movement, offering cookies, crackers, and other snacks that were marketed as guilt-free options due to their reduced fat content, despite being high in sugar and refined carbohydrates.
These examples demonstrate the food industry's pervasive influence on public opinion and dietary guidelines, perpetuating the idea that fat is the enemy while often promoting less healthy alternatives.
Based on those erroneous results, they spread fear using advertisements to create a culture of fear around fat, which led to the widespread adoption of low-fat diets.
Below are examples of advertisements and marketing campaigns from the 1950s through the 1990s, funded by the food industry, that promoted the idea that fat is the enemy:
1950s:
Mazola Corn Oil ads claimed that their product was "cholesterol-free" and "heart-healthy" compared to traditional fats like butter and lard, highlighting the supposed dangers of saturated fat.
An ad for Bran Buds cereal features a doctor telling viewers that "fat is the enemy" and that Bran Buds is a "low-fat cereal that's good for your heart."
1960s:
Skippy peanut butter launched a campaign promoting its product as a lower-fat, cholesterol-free alternative to butter, playing on concerns about heart health and saturated fat.
1970s:
The "Cholesterol-free" label became a widespread marketing strategy, with products like Fleischmann's margarine and Crisco oil promoting their products as healthier alternatives to butter and other traditional fats.
1980s:
The launch of the National Cholesterol Education Program in 1985 led to a surge in low-fat and cholesterol-free food products. Kellogg's, for example, advertised its Corn Flakes cereal as a low-fat, cholesterol-free option for breakfast.
An ad for SnackWell's cookies features a woman who is eating a cookie and says, "I can't believe these cookies are fat-free! They taste just like the real thing!"
In 1988, McLean Deluxe, a low-fat hamburger, was introduced by McDonald's, claiming to offer a healthier alternative to traditional burgers. The product was heavily marketed as a way for consumers to reduce their fat intake.
1990s:
SnackWell's, a brand of low-fat cookies and snacks, gained immense popularity during this decade. Their marketing campaigns emphasized that their products were low in fat, suggesting that they were healthier alternatives to traditional snacks.
An ad for Lean Cuisine features a woman who is eating a Lean Cuisine meal and says, "I can't believe I'm eating a healthy meal that's so delicious!"
These are just a few examples of advertisements and marketing campaigns from the 50s, 60s, 70s, 80s, and 90s funded by the food industry that show fat is the enemy. These ads helped to create a culture of fear around fat, which led to the widespread adoption of low-fat diets. However, there is no scientific evidence to support the claim that fat is bad for your health. In fact, studies have shown that people who eat a moderate amount of fat are less likely to develop heart disease, stroke, and other chronic diseases.
The food industry's promotion of the idea that fat is bad has had a number of negative consequences. First, it has led to people eating too little fat. This can be harmful to health, as fat is essential for the absorption of vitamins and minerals. Second, it has led to the development of low-fat foods that are often high in sugar and unhealthy carbohydrates. These foods are not healthier than their full-fat counterparts, and they may even be harmful to health.
The food industry's promotion of the idea that fat is bad is based on a number of false claims. One claim is that fat causes heart disease. However, there is no evidence to support this claim. In fact, studies have shown that people who eat a moderate amount of fat are less likely to develop heart disease.
Another claim is that fat makes you fat. However, this is also not true. The amount of fat you eat does not have a significant impact on your weight. In fact, studies have shown that people who eat a moderate amount of fat are less likely to be overweight or obese.
The food industry's promotion of the idea that fat is bad is a marketing ploy. It is designed to sell more low-fat foods. However, these foods are not healthier than their full-fat counterparts. In fact, they may even be harmful to health.
As we said in the beginning, it’s outrageous that the food industry has been successful to set the public opinion that fat is fad and we can see reminiscence in the grocery store. By no means we say that all fat is good. We will talk about good fat and fats to avoid later in the newsletter.
The Truth About Fat: Debunking Myths and Unpacking Facts
From Vilification to Vindication
Let's start by dismantling a pervasive myth: that fat is inherently bad. Contrary to this common misconception, fat is not our foe; it is, in fact, a vital ally. There are many viewpoints underscoring the benefits of fat, reflecting its central role in our evolutionary and cultural history.
Fat and Evolution: Fueling Our Survival
From an evolutionary standpoint, fat has been a linchpin in human survival and development. Fat is a dense source of energy, an essential resource for our ancestors, fueling their physical activities and maintaining their body temperature in challenging environments. Besides, fat is necessary for the absorption of fat-soluble vitamins like A, D, E, and K, indispensable for various biological functions. With the human brain composed of approximately 60% fat, fatty acids are crucial for proper cognitive development and function. Thus, our ancestors actively sought out sources of fat, satisfying their physiological needs and thriving in their environments.
Historical and Cultural Perspectives: The Fat-Grain Symbiosis
Across cultures, the pairing of grains and fats has been integral to culinary traditions. This combination not only enhances the taste, texture, and satiety of food, but it also offers numerous health benefits, like improved nutrient absorption and a positive impact on gut health. The prevalence of grain and fat pairings across cultures underscores the fundamental role of fat in human history and culinary heritage.
Let's take a gastronomic tour around the world, highlighting some quintessential grain-fat pairings:
India:
Paratha (Whole wheat flour + ghee/oil)
Rice and curry (Rice + ghee/coconut milk)
Middle East:
Hummus with pita bread (Pita bread + hummus)
Falafel in pita bread with tahini sauce (Pita bread + frying oil/tahini)

The Trinity of Cooking: The Pivotal Role of Fat
Fat, Fire, and Salt form the trinity of cooking. Beyond these three, everything else is optional. It's hard to imagine cooking without fat, whether it be plant-based oils or animal-based fats. Yet, the food industry has managed to villainize fat, a component so ubiquitous in our kitchens.
The food industry's marketing strategies were not just successful but also misleading, instilling fear around fat. We must remember to approach advertisements and marketing campaigns with a healthy dose of skepticism, follow the money trail, and consider who funded the research.
Scientific Perspective: The Turning Tide
Fortunately, the tides are turning. Modern nutrition science is challenging the long-held belief that fat is inherently harmful. Instead, it is shedding light on the numerous health benefits of consuming fats, especially unsaturated fats found in plant-based oils, nuts, seeds, and fish.
Research has shown that fat is essential for hormone production, cell membrane integrity, and the regulation of inflammation. Moreover, recent studies have debunked the myth that saturated fat is the primary cause of heart disease, pointing instead to the detrimental effects of excessive sugar and refined carbohydrate consumption. This growing body of evidence suggests that the vilification of fat is not only misguided but also detrimental to public health.
Towards a Balanced Understanding of Fat
Now that we've dispelled the myth of fat as the enemy, let's recognize the true villain: processed food. We've discussed eating clean in the past, and before diving into the relationship between fat and gut health, it was essential to address and dismantle the fear surrounding fat. Armed with a balanced understanding, we can now make informed decisions about our diet and health, appreciating the integral role that fat plays in our well-being.
