The short answer? At least in the United States? Yes. Let's look at the history and the reasons why. I post a lot of propaganda posters for World War Wednesday, and although it is implied, I don't point out often enough that they are just that - propaganda. They are designed to alter peoples' behavioral patterns using a combination of persuasion, authority, peer pressure, and unrealistic portrayals of culture and society. In the last several months of sharing propaganda posters on social media for World War Wednesday, I've gotten a couple of comments on how much they reflect an exclusively White perspective. Although White Anglo-Saxon Protestant culture was the dominant culture in the United States at the time, it was certainly not the only culture. And its dominance was the result of White supremacy and racism. This is reflected in the nutritional guidelines and nutrition science research of the time. The First World War takes place during the Progressive Era under a president who re-segregated federal workplaces that had been integrated since Reconstruction. It was also a time when eugenics was in full swing, and the burgeoning field of nutrition science was using racism as justifications for everything from encouraging assimilation among immigrant groups by decrying their foodways and promoting White Anglo-Saxon Protestant foodways like "traditional" New England and British foods to encouraging "better babies" to save the "White race" from destruction. Nutrition science research with human subjects used almost exclusively adult White men of middle- and upper-middle class backgrounds - usually in college. Certain foods, like cow's milk, were promoted heavily as health food. Notions of purity and cleanliness also influenced negative attitudes about immigrants, African Americans, and rural Americans. During World War II, Progressive-Era-trained nutritionists and nutrition scientists helped usher in a stereotypically New England idea of what "American" food looked like, helping "kill" already declining regional foodways. Nutrition research, bolstered by War Department funds, helped discover and isolate multiple vitamins during this time period. It's also when the first government nutrition guidelines came out - the Basic 7. Throughout both wars, the propaganda was focused almost exclusively on White, middle- and upper-middle-class Americans. Immigrants and African Americans were the target of some campaigns for changing household habits, usually under the guise of assimilation. African Americans were also the target of agricultural propaganda during WWII. Although there was plenty of overt racism during this time period, including lynching, race massacres, segregation, Jim Crow laws, and more, most of the racism in nutrition, nutrition science, and home economics came in two distinct types - White supremacy (that is, the belief that White Anglo-Saxon Protestant values were superior to every other ethnicity, race, and culture) and unconscious bias. So let's look at some of the foundations of modern nutrition science through these lenses. Early Nutrition ScienceNutrition Science as a field is quite young, especially when compared to other sciences. The first nutrients to be isolated were fats, carbohydrates, and proteins. Fats were the easiest to determine, since fat is visible in animal products and separates easily in liquids like dairy products and plant extracts. The term "protein" was coined in the 1830s. Carbohydrates began to be individually named in the early 19th century, although that term was not coined until the 1860s. Almost immediately, as part of nearly any early nutrition research, was the question of what foods could be substituted "economically" for other foods to feed the poor. This period of nutrition science research coordinated with the Enlightenment and other pushes to discover, through experimentation, the mechanics of the universe. As such, it was largely limited to highly educated, White European men (although even Wikipedia notes criticism of such a Euro-centric approach). As American colleges and universities, especially those driven by the Hatch Act of 1877, expanded into more practical subjects like agriculture, food and nutrition research improved. American scientists were concerned more with practical applications, rather than searching for knowledge for knowledge's sake. They wanted to study plant and animal genetics and nutrition to apply that information on farms. And the study of human nutrition was not only to understand how humans metabolized foods, but also to apply those findings to human health and the economy. But their research was influenced by their own personal biases, conscious and unconscious. The History of Body Mass Index (BMI)Body Mass Index, or BMI, is a result of that same early 19th century time period. It was invented by Belgian mathematician Lambert Adolphe Jacques Quetelet in the 1830s and '40s specifically as a "hack" for determining obesity levels across wide swaths of population, not for individuals. Quetelet was a trained astronomist - the one field where statistical analysis was prevalent. Quetelet used statistics as a research tool, publishing in 1835 a book called Sur l'homme et le développement de ses facultés, ou Essai de physique sociale, the English translation of which is usually called A Treatise on Man and the Development of His Faculties. In it, he discusses the use of statistics to determine averages for humanity (mainly, White European men). BMI became part of that statistical analysis. Quetelet named the index after himself - it wasn't until 1972 that researcher Ancel Keys coined the term "Body Mass Index," and as he did so he complained that it was no better or worse than any other relative weight index. Quetelet's work went on to influence several famous people, including Francis Galton, a proponent of social Darwinism and scientific racism who coined the term "eugenics," and Florence Nightingale, who met him in person. As a tool for measuring populations, BMI isn't bad. It can look at statistical height and weight data and give a general idea of the overall health of population. But when it is used as a tool to measure the health of individuals, it becomes extremely flawed and even dangerous. Quetelet had to fudge the math to make the index work, even with broad populations. And his work was based on White European males who he considered "average" and "ideal." Quetelet was not a nutrition scientist or a doctor - this "ideal" was purely subjective, not scientific. Despite numerous calls to abandon its use, the medical community continues to use BMI as a measure of individual health. Because it is a statistical tool not based on actual measures of health, BMI places people with different body types in overweight and obese categories, even if they have relatively low body fat. It can also tell thin people they are healthy, even when other measurements (activity level, nutrition, eating disorders, etc.) are signaling an unhealthy lifestyle. In addition, fatphobia in the medical community (which is also based on outdated ideas, which we'll get to) has vilified subcutaneous fat, which has less impact on overall health and can even improve lifespans. Visceral fat, or the abdominal fat that surrounds your organs, can be more damaging in excess, which is why some scientists and physicians advocate for switching to waist ratio measurements. So how is this racist? Because it was based on White European male averages, it often punishes women and people of color whose genetics do not conform to Quetelet's ideal. For instance, people with higher muscle mass can often be placed in the "overweight" or even "obese" category, simply because BMI uses an overall weight measure and assumes a percentage of it is fat. Tall people and people with broader than "ideal" builds are also not accurately measured. The History of the CalorieAlthough more and more people are moving away from measuring calories as a health indicator, for over 100 years they have reigned as the primary measure of food intake efficiency by nutritionists, doctors, and dieters alike. The calorie is a unit of heat measurement that was originally used to describe the efficiency of steam engines. When Wilbur Olin Atwater began his research into how the human body metabolizes food and produces energy, he used the calorie to measure his findings. His research subjects were the White male students at Wesleyan University, where he was professor. Atwater's research helped popularize the idea of the calorie in broader society, and it became essential learning for nutrition scientists and home economists in the burgeoning field - one of the few scientific avenues of study open to women. Atwater's research helped spur more human trials, usually "Diet Squads" of young middle- and upper-middle-class White men. At the time, many papers and even cookbooks were written about how the working poor could maximize their food budgets for effective nutrition. Socialists and working class unionists alike feared that by calculating the exact number of calories a working man needed to survive, home economists were helping keep working class wages down, by showing that people could live on little or inexpensive food. Calculating the calories of mixed-food dishes like casseroles, stews, pilafs, etc. was deemed too difficult, so "meat and three" meals were emphasized by home economists. Making "American" FoodEfforts to Americanize and assimilate immigrants went into full swing in the late 19th and early 20th centuries as increasing numbers of "undesirable" immigrants from Ireland, southern Italy, Greece, the Middle East, China, Eastern Europe (especially Jews), Russia, etc. poured into American cities. Settlement workers and home economists alike tried to Americanize with varying degrees of sensitivity. Some were outright racist, adopting a eugenics mindset, believing and perpetuating racist ideas about criminology, intelligence, sanitation, and health. Others took a more tempered approach, trying to convince immigrants to give up the few things that reminded them of home - especially food. These often engaged in the not-so-subtle art of substitution. For instance, suggesting that because Italian olive oil and butter were expensive, they should be substituted with margarine. Pasta was also expensive and considered to be of dubious nutritional value - oatmeal and bread were "better." A select few realized that immigrant foodways were often nutritionally equivalent or even superior to the typical American diet. But even they often engaged in the types of advice that suggested substituting familiar ingredients with unfamiliar ones. Old ideas about digestion also influenced food advice. Pickled vegetables, spicy foods, and garlic were all incredibly suspect and scorned - all hallmarks of immigrant foodways and pushcart operators in major American cities. The "American" diet advocated by home economists was highly influenced by Anglo-Saxon and New England ideals - beef, butter, white bread, potatoes, whole cow's milk, and refined white sugar were the nutritional superstars of this cuisine. Cooking foods separately with few sauces (except white sauce) was also a hallmark - the "meat and three" that came to dominate most of the 20th century's food advice. Rooted in English foodways, it was easy for other Northern European immigrants to adopt. Although French haute cuisine was increasingly fashionable from the Gilded Age on, it was considered far out of reach of most Americans. French-style sauces used by middle- and lower-class cooks were often deemed suspect - supposedly disguising spoiled meat. Post-Civil War, Yankee New England foodways were promoted as "American" in an attempt to both define American foodways (which reflected the incredibly diverse ecosystems of the United States and its diverse populations) and to unite the country after the Civil War. Sarah Josepha Hale's promotion of Thanksgiving into a national holiday was a big part of the push to define "American" as White and Anglo-Saxon. This push to "Americanize" foodways also neatly ignores or vilifies Indigenous, Asian-American, and African American foodways. "Soul food," "Chinese," and "Mexican" are derided as unhealthy junk food. In fact, both were built on foundations of fresh, seasonal fruits, vegetables, and whole grains. But as people were removed from land and access to land, the they adapted foodways to reflect what was available and what White society valued - meat, dairy, refined flour, etc. Asian food in particular was adapted to suit White palates. We won't even get into the term "ethnic food" and how it implies that anything branded as such isn't "American" (e.g. White). Divorcing foodways from their originators is also hugely problematic. American food has a big cultural appropriation problem, especially when it comes to "Mexican" and "Asian" foods. As late as the mid-2000s, the USDA website had a recipe for "Oriental salad," although it has since disappeared. Instead, we get "Asian Mango Chicken Wraps," and the ingredients of mango, Napa cabbage, and peanut butter are apparently what make this dish "Asian," rather than any reflection of actual foodways from countries in Asia. Milk - The Perfect FoodCombining both nutrition research of the 19th century and also ideas about purity and sanitation, whole cow's milk was deemed by nutrition scientists and home economists to be "the perfect food" - as it contained proteins, fats, and carbohydrates, all in one package. Despite issues with sanitation throughout the 19th century (milk wasn't regularly pasteurized until the 1920s), milk became a hallmark of nutrition advice throughout the Progressive Era - advice which continues to this day. Throughout the history of nutritional guidelines in the U.S., milk and dairy products have remained a mainstay. But the preponderance of advice about dairy completely ignores that wide swaths of the population are lactose intolerant, and/or did not historically consume dairy the way Europeans did. Indigenous Americans, and many people of African and Asian descent historically did not consume cow's milk and their bodies often do not process it well. This fact has been capitalized upon by both historic and modern racists, as milk as become a symbol of the alt-right. Even today, the USDA nutrition guidelines continue to recommend at least three servings of dairy per day, an amount that can cause long term health problems in communities that do not historically consume large amounts of dairy. Nutrition Guidelines HistoryBecause Anglo-centric foodways were considered uniquely "American" and also the most wholesome, this style of food persisted in government nutritional guidelines. Government-issued food recommendations and recipes began to be released during the First World War and continued during the Great Depression and World War II. These guidelines and advice generally reinforced the dominant White culture as the most desirable. Vitamins were first discovered as part of research into the causes of what would come to be understood as vitamin deficiencies. Scurvy (Vitamin C deficiency), rickets (Vitamin D deficiency), beriberi (Vitamin B1 or thiamine deficiency), and pellagra (Vitamin B2 or niacin deficiency) plagued people around the world in the 19th and early 20th centuries. Vitamin C was the first to be isolated in 1914. The rest followed in the 1930s and '40s. Vitamin fortification took off during World War II. The Basic 7 guidelines were first released during the war and were based on the recent vitamin research. But they also, consciously or not, reinforced white supremacy through food. Confident that they had solved the mystery of the invisible nutrients necessary for human health, American nutrition scientists turned toward reconfiguring them every which way possible. This is the history that gives us Wonder Bread and fortified breakfast cereals and milk. By divorcing vitamins from the foods in which they naturally occur (foods that were often expensive or scarce), nutrition scientists thought they could use equivalents to maintain a healthy diet. As long as people had access to vitamins, carbohydrates, proteins, and fats, it didn't matter how they were delivered. Or so they thought. This policy of reducing foods to their nutrients and divorcing food from tradition, culture, and emotion dates back to the Progressive Era and continues to today, sometimes with disastrous consequences. Commodities & NutritionDivorcing food from culture is one government policy Indigenous people understand well. U.S. treaty violations and land grabs led to the reservation system, which forcibly removed Native people from their traditional homelands, divorcing them from their traditional foodways as well. Post-WWII, the government helped stabilize crop prices by purchasing commodity foods for use in a variety of programs operated by the United States Department of Agriculture (USDA), including the National School Lunch Program, Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), and the Food Distribution Program on Indian Reservations (FDPIR) program. For most of these programs, the government purchases surplus agricultural commodities to help stabilize the market and keep prices from falling. It then distributes the foods to low-income groups as a form of food assistance. Commodity foods distributed through the FDPIR program were generally canned and highly processed - high in fat, salt, and sugar and low in nutrients. This forced reliance on commodity foods combined with generational trauma and poverty led to widespread health disparities among Indigenous groups, including diabetes and obesity. Which is why I was appalled to find this cookbook the other day. Commodity Cooking for Good Health, published by the USDA in 1995 (1995!) is a joke, but it illustrates how pervasive and long-lasting the false equivalency of vitamins and calories can be. The cookbook starts with an outline of the 1992 Food Pyramid, whose base rests on bread, pasta, cereal, and rice. It then goes to outline how many servings of each group Indigenous people should be eating, listing 2-3 servings a day for the dairy category, but then listing only nonfat dry milk, evaporated milk, and processed cheese as the dairy options. In the fruit group, it lists five different fruit juices as servings of fruit. It has a whole chapter on diabetes and weight loss as well as encouraging people to count calories. With the exception of a recipe for fry bread, one for chili, and one for Tohono O'odham corn bread, the remainder of the recipes are extremely European. Even the "Mesa Grande Baked Potatoes" are not, as one would assume from the title, a fun take on baked whole potatoes, but rather a mixture of dehydrated mashed potato flakes, dried onion soup mix, evaporated milk, and cheese. You can read the whole cookbook for yourself, but the fact of the matter is that the USDA is largely responsible for poor health on reservations, not only because it provides the unhealthy commodity foods, but also because it was founded in 1862, the height of the Indian Wars, during attempts by the federal government at genocide and successful land grabs. Although the Bureau of Indian Affairs (BIA) under the Department of the Interior was largely responsible for the reservation system, the land grant agricultural college system started by the Hatch Act was literally built on the sale of stolen land. In addition, the USDA has a long history of dispossessing Black farmers, an issue that continues to this day through the denial of farm loans. Thanks to redlining, people of color, especially Black people, often live in segregated school districts whose property taxes are inadequate to cover expenses. Many children who attend these schools are low-income, and rely on free or reduced lunch delivered through the National School Lunch Program, which has been used for decades to prop up commodity agriculture. Although school lunch nutrition efforts have improved in recent years, many hot lunches still rely on surplus commodities and provide inadequate nutrition. Issues That PersistEven today, the federal nutrition guidelines, administered by the USDA, emphasize "meat and three" style meals accompanied by dairy. And while the recipe section is diversifying, it is still all-too-often full of Americanized versions of "ethnic" dishes. Many of the dishes are still very meat- and dairy-centric, and short on fresh fruits and vegetables. Some recipes, like this one, seem straight out of 1956. The idea that traditional ingredients should be replaced with "healthy" variations, for instance always replacing white rice with brown rice or, more recently cauliflower rice, continues. Many nutritionists also push the Mediterranean Diet as the healthiest in the world, when in fact it is very similar to other traditional diets around the world where people have access to plenty of unsaturated fats, fruits and vegetables, whole grains, lean meats, etc. Even the name - the "Mediterranean Diet," implies the diets of everyone living along the Mediterranean. So why does "Mediterranean" always mean Italian and Greek food, and never Persian, Egyptian, or Tunisian food? (Hint: the answer is racism). Old ideas about nutrition, including emphasis on low-fat foods, "meat and three" style recipes, replacement ingredients (usually poor cauliflower), and artificial sweeteners for diabetics, seem hard to shake for many people. Doctors receive very little training in nutrition and hospital food is horrific, as I saw when my father-in-law was hospitalized for several weeks in 2019. As a diabetic with problems swallowing, pancakes with sugar-free syrup, sugar-free gelatin and pudding, and not much else were their solution to his needs. The modern field of nutritionists is also overwhelmingly White, and racism persists, even towards trained nutritionists of color, much less communities of color struggling with health issues caused by generational trauma, food deserts, poverty, and overwork. Our modern food system has huge structural issues that continue to today. Why is the USDA, which is in charge of promoting agriculture at home and abroad, in charge of federal nutrition programs? Commodity food programs turn vulnerable people into handy props for industrial agriculture and the economy, rather than actually helping vulnerable people. Federal crop subsidies, insurance, and rules assigns way more value to commodity crops than fruits and vegetables. This government support also makes it easy and cheap for food processors to create ultra-processed, shelf-stable, calorie-dense foods for very little money - often for less than the crops cost to produce. This makes it far cheaper for people to eat ultra-processed foods than fresh fruits and vegetables. The federal government also gives money to agriculture promotion organizations that use federal funds to influence American consumers through advertising (remember the "Got Milk?" or "The Incredible, Edible Egg" marketing? That was your taxpayer dollars at work), regardless of whether or not the foods are actually good for Americans. Nutrition science as a field has a serious study replication problem, and an even more serious communications problem. Although scientists themselves usually do not make outrageous claims about their findings, the fact that food is such an essential part of everyday life, and the fact that so many Americans are unsure of what is "healthy" and what isn't, means that the media often capitalizes on new studies to make over-simplified announcements to drive viewership. Key TakeawaysNutrition science IS a science, and new discoveries are being made everyday. But the field as a whole needs to recognize and address the flawed scientific studies and methods of the past, including their racism - conscious or unconscious. Nutrition scientists are expanding their research into the many variables that challenge the research of the Progressive Era, including gut health, environmental factors, and even genetics. But human research is expensive, and test subjects rarely diverse. Nutrition science has a particularly bad study replication problem. If the government wants to get serious about nutrition, it needs to invest in new research with diverse subjects beyond the flawed one-size-fits-all rhetoric. The field of nutrition - including scientists, medical professionals, public health officials, and dieticians - need to get serious about addressing racism in the field. Both their own personal biases, as well as broader institutional and cultural ones. Anyone who is promoting "healthy" foods needs to think long and hard about who their audience is, how they're communicating, and what foods they're branding as "unhealthy" and why. We also need to address the systemic issues in our food system, including agriculture, food processing, subsidies, and more. In particular, the government agencies in charge of nutrition advice and food assistance need to think long and hard about the role of the federal government in promoting human health and what the priorities REALLY are - human health? or the economy? There is no "one size fits all" recommendation for human health. Ever. Especially not when it comes to food. Because nutrition guidelines have problems not just with racism, but also with ableism and economics. Not everyone can digest "healthy" foods, either due to medical issues or medication. Not everyone can get adequate exercise, due to physical, mental, or even economic issues. And I would argue that most Americans are not able to afford the quality and quantity of food they need to be "healthy" by government standards. And that's wrong. Like with human health, there are no easy solutions to these problems. But recognizing that there is a problem is the first step on the path to fixing them.

Exploring the biases in nutrition science is crucial to understanding how dietary guidelines might not serve everyone equally. It's time to address these disparities and promote inclusive health standards.
