The Foreign Policy of the Calorie

A too naïve theory used to prevail for explaining regeneration through food. The human system was thought of as an engine, and you kept it stoked with foods to produce energy.

Irma S. Rombauer and Marion Rombauer Becker, Joy of Cooking (1975)

In Super Size Me , his documentary on the fast-food industry, Morgan Spurlock asks ninth-graders in Brooklyn, West Virginia, to define a calorie. A few shake their heads, but most gamely guess that it has something to do with fat. "It's something you should count," one advises. "It's on the side of the cereal box," explains another. The adults interviewed fare little better. "Calories are not good," one man knows for sure. Even the specialist who finally has an answer studies the ceiling for a minute before recalling that a calorie is a measure of the energy content of food, an amount sufficient to raise the temperature of one kilogram of water one degree. One might try the same experiment with other numerical yardsticks used to gauge individual or social well-being—GNP, T-cell counts, or crime rates—and find a similar cultural lost-wax process: the soft material of objective measurement falls away, leaving a subjective impression on the things measured. The ninth-graders had fully absorbed the governmentality of the calorie; they understood that it patterns food with particular obligations, aesthetic and hygienic norms, and techniques of management. Knowing too much about an indicator's original purpose, or what it actually records, might only diminish its authority. ¹

In the first half of the twentieth century, the arithmetic of standards of living, revenues, education, and population gained significance in assessments of the relative status of states and empires. As doctrines of development first began to inform the practice of international relations, numerical indicators prepared the way, jumping linguistic boundaries and displacing local knowledge and native informants. The empiricism of states and international institutions, Timothy Mitchell contends, acquired a "character of calculability" that mediated between material realities and the abstractions of science and politics. Neither constructed nor imagined but fabricated from a mix of cultural and material ingredients, numerical indicators were tangible enough to mold facts. They were the conceptual components of a new realism in international affairs. ²

Historians and theorists of foreign relations often associate number with explanatory rigor. Although E. H. Carr, Hans J. Morgenthau, Charles Beard, and other founders cautioned against scientism, realist and revisionist historiographies grew to recognize quantifiable material factors as the constituents of international reality, exercising, according to Jeffrey W. Legro and Andrew Moravcsik, "an exogenous influence on state behavior no matter what states seek, believe, or construct." More recently, scholars have employed measurability to distinguish between established analytic methods and cultural or "constructivist" approaches bidding for scholarly credibility. The history of the calorie suggests a few of the problems with this distinction. As Spurlock's ninth-graders revealed, supposedly "hard" data came laden with presuppositions that were cultural but not superficial. In the early part of the twentieth century, "food" lost its subjective, cultural character and evolved into a material instrument of statecraft. To do so, it had to be quantifiable, but its numerical index also had to be furnished with a suitable context of goals, analogies, and claims. ³

Although few statistical measures seem more innocuous, the calorie has never been a neutral, objective measure of the contents of a dinner plate. From the first, its purpose was to render food, and the eating habits of populations, politically legible. In this sense it was one of the lesser tools facilitating a widening of the state's supervision of the welfare and conduct of whole populations that has been referred to in different contexts as state building, modernism, or regulating the social. It was also instrumental in a transformation in the ethics of hunger identified by James Vernon in an earlier issue of this journal: to be defined as a social problem, hunger had first to be precisely quantified. The calorie was also a technology for classifying food within the inventory of resources (the "standing reserve") at the disposal of the state. As such, it had a part in an evolving developmental discourse that registered the requirements and aspirations of nations largely in numerical terms. ⁴

Europeans first measured food in calories, but Americans constructed the calorie by giving it practical value, standardizing it and embedding it in systems of distribution and administration. It was in the United States that the calorie left its most visible imprint on foreign policy. It popularized and factualized a set of assumptions that allowed Americans to see food as an instrument of power, and to envisage a "world food problem" amenable to political and scientific intervention. In 1974, J. George Harrar, president of the Rockefeller Foundation, maintained that the discovery of the calorie had led directly to an "informal alliance" of "scientists, farmers, government agencies, educators, and processors" working to eliminate famine worldwide. A closer examination of the calorie's early years, however, shows that the path from knowledge to organization was not quite so straightforward. Scientific food measurement authorized and guided a succession of different schemes of food management. The U.S. government first employed the calorie during the Progressive Era, as a gauge of social and industrial efficiency. It was adopted by military planners to marshal scarce resources during World War I, and was disseminated along with relief supplies to stricken areas of Europe. In the interwar years, numeration opened the way for competing imperial, autarkic, and internationalist food regimes, each applying quantitative logic toward different ends. The current world pattern of humanitarianism, exchange, and subsidized dumping began to emerge only after the Anglo-American allies recaptured the calorie among the spoils of World War II. ⁵

Today, the problem of "world hunger" is characterized by a style of calculability that assigns reciprocal routines and obligations to national governments and the international community. Topping the list of the United Nations' Millennium Development Goals is the commitment to "halve, by the year 2015, the proportion of the world's people who suffer from hunger." The UN World Food Programme (WFP) marks progress on its website with an "interactive hunger map" on which the outlines of the caloric deficit align with national frontiers; hungry nations are marked in bright red, while cooler shades of blue and green indicate progressive degrees of satiety. The image sharpens the juxtaposition of surplus and dearth, visually conveying a reproof familiar to youngsters of a certain generation: "Clean your plate; there are starving children in China." This understanding of the reciprocity of abundance and shortage rests on a claim that "food" has a uniform meaning in green nations and red nations and a standard value that can be tabulated as easily as currency or petroleum. The calorie represents the sum of these assumptions. ⁶

The work of rendering food into hard figures began just after breakfast on Monday, March 23, 1896, when Wilbur O. Atwater sealed a graduate student into an airtight chamber in the basement of Judd Hall on the Wesleyan University campus. The apparatus was described by the press as resembling a meat locker, a room "about as large as an ordinary convict's cell" lined with copper and zinc, its interior visible through a triple-paned glass aperture. Its occupant, A. W. Smith, took measured quantities of bread, baked beans, Hamburg steak, milk, and mashed potatoes through an airlock during rest periods, which alternated with intervals of weightlifting and mental exertion, "studying German treatises on physics and the like." Meanwhile, thermometers, hygrometers, and electrically powered condensers, pumps, and fans precisely measured the movement of heat, air, and matter into and out of the chamber. Smith was inside a calorimeter, a device previously used to measure the combustive efficiency of explosives and engines. It recorded his food intake and labor output in units of thermal energy. ⁷

The national penny press found a Chekhovian parable in the "Wesleyan glass cage," printing "sensational" and "wholly imaginary" reports on the voluntary captivity of Smith, alternately described as "the man in the box" and "the prisoner of science." On the second day of the experiment, Atwater had to turn away a young New York woman who appeared at the lab asking to be allowed to take Smith's place in the chamber, but despite distractions, the calorimeter's first run was an enormous success, generating pages of data and a $10,000 congressional appropriation. The Department of Agriculture (USDA) built a copy of Atwater's device in Washington, D.C., and Francis Benedict, another of Atwater's students, persuaded the Carnegie Institute to construct a larger and more elaborate version at Harvard University. ⁸

Subsequent experiments attracted equally keen interest. Atwater invited champion cyclist Nat Butler into the calorimeter to establish "how far a man ought to ride a bicycle on one egg." Wesleyan's football captain volunteered to take his French final inside to help determine the quantum of heat generated by an hour of cogitation. But it was the statistical results issuing from Middletown after 1899—tables that assigned calorie counts to specific foods and tasks—that stirred up national controversy and made Atwater a household name. Clergymen applauded his discovery that the body created in the divine image produced energy more efficiently than a locomotive. The Women's Christian Temperance Union organized an anti-Atwater campaign when he confirmed—by sustaining a test subject for six days on a diet "largely composed of alcohol"—that liquor was a food. But most sensational of all was Atwater's pronouncement that mathematical laws governed the ordinary act of eating. ⁹

As federal officials recognized, the calorimeter had ramifications for the management of factories, prisons, and schools, as well as the provisioning of armies. It could reduce the cost of rations, and test their suitability for the tropics and for varying conditions of work. Atwater expected an even greater benefit. For the first time, scientists would be able to make precise comparisons between the diets of different social classes and nations. Excusing himself from negotiations with Japan in November 1908, Secretary of State Elihu Root traveled to Boston for the "express purpose" of seeing the Carnegie calorimeter, proclaiming it an "invaluable invention." Journalists anticipated that its greatest impact would be on the "Asiatic races," whose improvement could begin once their diet was brought up to an American standard. Economic and social progress in Asia would have to await nutritional progress, the Review of Reviews observed, since "what can we expect either of physical or moral vigor from communities who live on the physical plane of millions in the Orient?" With a numerical gauge, Americans could begin to imagine the influence to be gained by manipulating the diets of distant peoples. The calorie, Atwater declared, would determine the "food supply of the future." ¹⁰

As Atwater's invention came into use as an international measure of food value in the early twentieth century, a number of important claims and metaphors gained acceptance with it, constituting a scientifically authorized, "realistic" view of the international food regime. These included a conviction that food was uniform and comparable between nations and time periods; that the state had an obligation to ensure a "balance" between the supply of food and the dietary needs of the nation; that wheat was uniquely important as an international conveyor of bulk food value; and that the interests of world peace might ultimately require a global food balance rationalized through some form of international regulation. At the time, these ideas did not constitute a policy but only a direction for policy, a notion of which way progress was headed and where the United States could lead.

Official enthusiasm for Atwater's experiments indicated the degree to which the need for an index of food consumption had already been recognized. Before the invention of a quantitative measure, it was difficult to speak of food in competitive, evolutionary terms, or to foresee the direction that improvements might take. While mechanical efficiency could be measured by mechanical means, no scale had yet been devised to assess human fuel. Notions of efficiency applied only loosely to agriculture—which relied on uncontrolled inputs, such as sunshine and rainfall—and even less to cooking or eating. The "science" of nutrition was largely the domain of vegetarians and iconoclasts, such as Horace Fletcher and John Harvey Kellogg, who judged diet by moral and aesthetic criteria rather than the objective, numerical standards of an industrial age. The son of a Methodist minister, Atwater began his nutritional research at Yale in this vein, but graduate work in Berlin and Leipzig introduced him to the chemical and physiological studies of Carl von Voit and Ludwig Max Rubner in Germany and Armand Gautier in Paris. The handful of biochemists conducting dietary observations in Europe in the 1880s formed a scientific avant-garde, working with little official support in the face of skepticism from leading biologists and physicians, but Atwater, on returning to the United States, found industrialists, universities, and state and federal governments eager to fund nutritional research. ¹¹

Atwater framed his investigations as a tool of "scientific management," allied with Frederick Winslow Taylor's efforts to resolve industrial unrest through the methodical study of time and motion. In strike actions and congressional debates, representatives of labor argued for leisure, meat, and bread as matters of justice, but scientific reformers presented them instead as issues of efficiency and cost. Proceeding from a Taylorist conception of a mechanomorphic body, Atwater led an effort by manufacturers, municipalities, and the federal government to set scientific "standards of living" that could be used to contain wage levels while maintaining a healthy, contented workforce. Between 1885, when he designed the first survey of factory workers in Massachusetts, and 1910, nutritionists conducted more than five hundred investigations of the eating habits of inhabitants of slums, boarding schools, Indian reservations, Chinese railroad camps, and Georgia plantations, but researchers were unsatisfied with their findings. Predictably, unions and individual subjects resisted efforts to locate their wage floor. More disturbing, the growing pile of surveys documented an almost unclassifiable diversity of food customs, yielding data that only complicated the reformist argument for enforcing norms. Atwater, in collaboration with Rubner and Gautier, began investigating a system for rendering food and labor into thermal units. ¹²

The necessity of a standard gauge was evident at the 1893 Columbian Exposition in Chicago. Among the least visited but most impressive exhibits was the Agricultural Building, a glass-domed arcade housing nineteen acres of distinctive foods—French cheeses, Indian curries, Javanese coffees, Greek oils, and an eleven-foot statue of Germania carved from a solid block of chocolate. "In walking through the corridors of this Agricultural Building, the earth and its nations seem drawn up for martial review," commented one juror. "The history of the older nations, the customs of the new, the social status of all, are revealed." But the terms of comparison were unclear. Although care was taken to impose a taxonomic order, the effect on the viewer was of a culinary Babel. Mechanical displays excited "wonder and admiration" for being "more typical of the genius of America," a reporter noted, but the Agricultural Building was more apt to evoke "a strain of idealistic poetry." The raw variety of comestibles impelled exhibitors to identify underlying principles supporting claims to advancement. The United States backed its displays with statistical charts showing the volume of grain production, while France mounted diagrams tracking the price of bread from 1830 to 1891, and Ceylon illustrated its share of Asian and European tea markets. At Chicago, "the line of triangulation into the future," Henry Adams observed, was measured in units of "power, tonnage, and speed," but in the Agricultural Building the heterogeneity of flavor, color, and custom simply yielded to an equally ambiguous surfeit of numbers. ¹³

This metrical handicap excluded food from the turn toward statistical reasoning that was altering social debate in the United States. Americans increasingly digested information in numerical form. In 1898, the U.S. Bureau of Statistics reformatted its publications to increase their influence and circulation; instead of annual compilations, it issued weekly bulletins containing the latest figures. The Census Bureau followed suit, issuing serialized dispatches highlighting correlations culled from its decennial reports. Official figures only augmented a growing stream of private data. The public learned the risks of accident, typhoid, and homicide from monthly actuarial digests issued by insurance companies. After 1905, gamblers judged horses by the statistical portents in the Daily Racing Form, and baseball fans sized up hitters by the tables in The Sporting News. Newspapers published an avalanche of statistics evaluating business acumen by quarterly earnings, literature by copies sold, and drama by the number of weeks on Broadway. Historians have described the metric revolution nurtured by the great European bureaux statistiques in the nineteenth century, but to contemporary observers in the twentieth, this shift toward mass consumption of statistics appeared to be a new and not altogether positive development. ¹⁴

Numerical expression fostered an altered worldview both more definite about solutions to complex problems and more attuned to indicators of rising and falling fortunes, especially among nations. Moral and legal argument had lost authority, Princeton historian Winthrop More Daniels remarked in 1902: "today the man of average intelligence ... has in his mental make-up a numerical frame-work, more or less exact, in which unconsciously the main facts of political and economic geography comfortably pigeonhole themselves." Instead of holding a fixed place in a hierarchy of inherently dissimilar races and nations, Americans could track their country's movement along a sliding scale of humanity on any number of axes of advancement. Carroll D. Wright, a Labor Department statistician, noted that "it is nothing rare for a public man to ask an official statistician to give him offhand the average wages paid in the United States or the wages paid in half a dozen designated countries, or to state in a few lines the criminal conditions or ... the cost of producing various articles in different countries." Official discourse consisted in such comparisons, which defined problems and indicated the urgency of commercial and military threats. Many observers considered such quantitative reasoning a modern and distinctly American trait. "If the English are a nation of shopkeepers, Americans are a nation of expert accountants," critic and playwright Eugene Richard White observed. "We go about reforming and purifying the world with a committee report at elbow and a statistical compilation in each hand." ¹⁵

The calorimeter thus translated the vernacular customs of food into the numerical language of empire. Atwater revolutionized nutritional science, as historian Hillel Schwartz observes, by theorizing food "without reference to taste, ethnic tradition, or social context," but he changed his field in other ways, too. Under his direction, the discipline of nutrition left its descriptive, reformist roots and became a quantitative, technocratic specialization. Where diet experts had formerly directed advice at individual patients, they now studied whole populations at the behest of the state. Their terms of analysis adapted to the new calculative logic; the critique of working-class diets receded, and the notion of an "American diet" to be compared with other national diets assumed prominence. The calorie lent food a conceptual coherence and established boundaries and hierarchies that defined it as a social object. Atwater's schedules ranked grain, meat, and dairy goods as important national resources, while fruits, leafy vegetables, and fish registered such slight nutritional value that they could scarcely be classified as food. Tea, coffee, and spices, on which whole imperial systems had once flourished, had no value at all. ¹⁶

The calorie represented food as uniform, composed of interchangeable parts, and comparable across time and between nations and races. In 1911, C. F. Langworthy, who succeeded Atwater as the head of nutrition investigations at USDA, compiled surveys undertaken by missionaries and ethnographers into a ranked list of the peoples of "each country and each epoch" on a scale of daily caloric consumption, with the "native laborer" of the Congo at the bottom (2,812 calories) and the American athlete at the top (4,510 calories). Challenging dietary theories of racial difference, Langworthy stressed that the human diet was far less diverse than had formerly been thought. Broken down into chemicals, the potatoes and cheese that fed the Irish laborer were identical, except in quantity, to the rice and ghee that nourished an Indian coolie. The central component in every diet was nitrogen, the element that lent "energy value" to meat, milk, and wheat. The thermodynamic theory of nutrition superseded whole systems of colonial knowledge of "useful plants," native diets, and the "seasoning" of Europeans in the tropics. Langworthy could also reassure Americans that their nitrogen-rich diet constituted the "finest food supply of any country in the world." ¹⁷

Treating societies as closed systems, nutritionists suggested that a "physiological economy" of food governed institutions and nations, and that "scientific eating" based on caloric "bookkeeping" would increase national efficiency. Langworthy and Atwater identified "balance" as characteristic of a progressive diet, and enumerated several ways that personal and market behavior could be modified to square the food ledger: individuals should balance physical exertion and caloric consumption; meals should balance luxury proteins against necessary carbohydrates; and economic policies should match supplies, on the basis of calories, to the specific requirements of populations. As a measure of optimization, the calorie represented a significant advance over the kinds of statistics used since the eighteenth century. Officials had studied tables of tax receipts, birth rates, harvests, mortality, and crime to discover natural laws and constants in human behavior that would serve as foundations for policy, but the calorie revealed a wide discrepancy between "natural" behavior and the ideal balance that might be achieved through social regulation. As Atwater and Langworthy never tired of pointing out, people of all classes and educations ate the wrong things in the wrong amounts, and neither the appetite nor the market could accurately assess needs. So while nineteenth-century statistics guided and limited the state, the calorie prefigured the use of gross national products, poverty rates, intelligence quotients, and the panoply of indices that in the twentieth century authorized government to tell people what was best for them. ¹⁸

Figure 2: Advertisers exploited the calorie's ability to present scientific comparisons between dissimilar foods. Nutritionists also used it to compare national diets. Washington Post, July 25, 1903, 2; Los Angeles Times, August 16, 1915, ii2.

Calories presented a thin simplification of nutrition better suited to gauging large populations than to guiding personal eating habits, as physicians repeatedly pointed out. In 1917, the American Medical Association warned against the "unwise domination" of the calorie in the popular mind, but its use persisted through the enthusiasm of advertisers, who emblazoned calorie counts on cereal boxes and instructed consumers that "calories measure food energy the same as dollars measure money." The federal government also eagerly seized upon the calorie to fill an urgent need for statistical information on food. After war broke out in Europe, speculative runs on commodities and food panics in major U.S. cities revealed the inadequacy of both the market mechanism and official knowledge. The agriculture department needed to balance Europe's requirements against the danger of domestic scarcity, but, the secretary admitted to congressional investigators, "where the food supply is located, who owns it, what may be the difficulties of securing it, whether the local market conditions are due to shortage, whether there can be artificial manipulation or control, no one can state with certainty." Combined with censuses, caloric tables could be used to estimate rations for cities, armies, or even nations. Military rather than hygienic necessity made the calorie an international standard measure of food. ¹⁹

Under pressure of war, the successful marshaling of food consumption and production became a state responsibility. American observers paid anxious attention to the warring powers' use of blockades to starve their adversaries to defeat. Correspondents assessed the offerings of restaurants and meat markets and the caloric content of soldiers' rations. The New York Times suggested that Germany, with its ports sealed, represented a closed chamber within which national energy and food production would have to balance. When a group of American engineers organized a massive food drive for occupied Belgium, they turned to the new "science of dietetics," which, having been rescued from "the hands of vegetarians and other extremists, seem[ed] at last to have arrived upon solid ground." The commission calculated purchases and rations on the basis of calories, which it considered "almost the only thing to be considered" in managing famine relief. As U.S. supplies became critical on both sides of the Western Front, Europeans learned to calculate food by American numbers. ²⁰

In the United States, mobilization for war began in 1917 when President Woodrow Wilson created a national food authority under the leadership of Herbert Hoover, a mining engineer and chief organizer of the Belgium relief. From his headquarters in the Willard Hotel, Hoover launched a drive to conserve sugar, fats, and grain for export to the front. Administrators took immediate steps to expand the cultivation of wheat, "by far" the most essential commodity because of its portability, abundance, and destabilizing potential. Dry, compact, and calorie-dense, wheat could "stand shipment" better than other staples. Despite a poor 1917 crop, "our stock of wheat offered the largest supply of calories available from any single raw food material," officials noted. More importantly, riots in American cities and Hoover's own experience in Belgium confirmed that shortages of bread led to unrest. The "industrial classes" valued wheat as an affordable luxury, and consequently "bread affects the morale of a people more quickly than any other food." European governments had long recognized this requirement for domestic order, but Hoover stressed its symbolic and practical ramifications for U.S. strategy. In the midst of war, he told his staff, "the wheat loaf has ascended in the imagination of men, women, and children as the emblem of national survival and national tranquility." ²¹

In Hoover's view, the net outflow of 20 million bushels would leave a morale deficit in the United States that could be filled only by social discipline. Over the heads of striking farmers and protesting bakers, Hoover appealed to his "police force—the American woman" to enforce wheatless Wednesdays and flourless "victory meals." As an instructional tool, the calorie was indispensable for setting rations, identifying substitutes, and defining the patriotic self-control expected of citizens. "You should know and also use the word calorie as frequently, or more frequently, than you use the words foot, yard, quart, [or] gallon," instructed one guidebook, "Instead of saying one slice of bread, or a piece of pie, you will say 100 calories of bread, 350 calories of pie." Consuming surplus calories amounted to "overeating," which sapped personal and national efficiency. Manhattan restaurants helpfully listed calorie counts next to each item along with the recommended totals for each "walk of life." ²²

The conscription of individual appetites disturbed conventional distinctions between public duty and personal conduct. Leading churchman Lyman Abbot disparaged calorie counting as "spiritual hypochondria," while another critic wistfully recalled days when "the highest science known to eating was to be able to balance green peas on a knife." Hoover deployed "higher mathematics ... to order your lives and grub." An unnamed Philadelphia poet lampooned the specter Hoovering over every American hearth: "An' all us other children when our scanty meal is done, / We gather round the fire and has the mostest fun / A-listnin' to the proteins that Herbie tells about / An' the Calories that git you ef you don't watch out!" ²³

Historians have described the enduring effect that war rationing had on perceptions of diet and body image, and social theorists have associated the emergence of modern sovereignty with a move from "wholesale" methods of policing to "retail" forms in which individuals internalize state demands as rules of personal behavior. Hoover summed up the point in the slogan "Centralize ideas but decentralize execution." He stressed an intimate connection between the "test" of bodily discipline and the trials that would face the nation during the war emergency and after. Personal dietary sacrifice indicated the United States' arrival at a "stage of development" at which it was prepared to "protect its own institutions and those of Europe." Russia had never attained that stage, he argued, "and the result has been a massacre." He urged Americans to seek "victory over ourselves; victory over the enemy of freedom." ²⁴

Hoover defined food as both a core vulnerability in the international order and an instrument of U.S. influence. Experts from the United States Food Administration created a ledger of global food resources and caloric requirements, and shortly before the armistice, Hoover informed Wilson that the United States would have to undertake relief efforts in forty-five nations "if we are to preserve these countries from Bolshevism and rank anarchy." Britain and France continued the blockade after the armistice, but U.S. officials, with Hoover in the lead, pressured them to lift it. The new American Relief Administration (ARA) then poured food through every German port. It took control of telegraph, treasuries, and transport. "In this crisis, we dominated central and southeastern Europe," an ARA official observed. "Our problem was to feed and rehabilitate countries inhabited by eighty-five million people." Allied and enemy governments received aid on equal terms, and the ARA even dealt with Bela Kun's Soviet regime in Hungary while conspiring to overthrow it. Distinctions between allies and enemies offered only temporary security, Hoover insisted; ultimately, resources and distribution would make the difference between war and peace, order and revolution. ²⁵

In defining security, Hoover rejected traditional balance-of-power concerns as well as Wilson's emphasis on international law and world opinion. Among the earliest and most forceful proponents of a novel strategic concept that linked security to social welfare, he located the germ of future wars in reaction and revolution incubated by scarcity. Material abundance bred stability, he argued, but "famine breeds anarchy. Anarchy is infectious, the infections of such a cess-pool will jeopardize France and Britain, [and] will yet spread to the United States." Hunger and unemployment "will not be cured at all by law or by legalistic processes," he warned, nor by nationalism or Bolshevism, although desperate populations would take up radical creeds. To forestall war, he believed, the United States would have to provide, in example and theory, an alternative route to progress, a progress measured in standards of living. ²⁶

Hoover disdained the "indescribable malignity" of Paris, often feeling alone in his conviction that safety could not be ensured by treaties, plebiscites, or border adjustments, but influential delegates, including leading socialists and members of inter-Allied mobilization councils, shared his hope for a peace based on managed social and economic amelioration. British economist John Maynard Keynes and French planners Jean Monnet and Albert Thomas each advocated technocratic direction of production and consumption as an alternative to the instability inherent in the prewar laissez-faire model. Charles S. Maier has catalogued the diverse European constituencies that sought salvation from reparations and industrial conflict in Taylorist and Fordist methods. But Hoover seemed more interested in defining exceptionalism than in fostering commonality. He sought to position scientific management as a uniquely American ideological response to Leninism. ²⁷

Believing that the appeal of radical doctrines lay in their ability to explain crisis and progress through iron laws of history and economics, Hoover set out to define an "American substitute" for "these disintegrating theories of Europe." His American Individualism (1922) laid out a stage theory of history, modeled on Marx but culminating in an era of "high pitch" mass consumption. Transitions between phases were marked not by crisis, but by innovations in cooperation that would "enable us to synchronize socially and economically this gigantic machine which we have built out of applied science." Techniques of social optimization—such as advertising, standardization, market research, and dietetics—would harmonize wages, production, consumption, labor, and health. More importantly, they sublimated ideological demands for peace, land, and bread within a neutral, quantitative language of entitlement. Optimization opened pathways to progress that bypassed developmental dead-ends predicted by Marx and Malthus. Poverty represented not the crisis of capitalism but the open frontier of the market without limits. In the modern age, security would rest on an ability to dominate the strategic terrain of global consumption. "There are continents of human welfare," he affirmed, "of which we have penetrated only the coastal plain." ²⁸

In 1920, Chase Osborn , Michigan's progressive governor, modestly proposed that the postwar system of international trade employ the calorie as a universal currency. A secure, expanding commerce, he explained, rested more solidly on units of sustenance than on the "imaginary" value of metal. "Nothing has value beyond its use in giving and sustaining life ... The quest of the calorie instead of the quest of wealth in gold would be the seeking of a permanent and not a changeable good." In the years following the armistice, claims to legitimacy increasingly came to be expressed in the idiom of development. As weakened metropolitan powers struggled to justify stewardship over restive colonies, and citizens, politicized by wartime sacrifices, demanded recognition of an entitlement to welfare, leaders sought political solutions in the economic and scientific spheres. But without a unified conception of civilization or "the West," development was necessarily a fractured discourse, with colonial, international, and national variants vying to fix norms of social achievement. Quantitative measurement, as Osborn's creative proposal suggested, offered innovative possibilities for expressing claims to developmental authority. Although Americans encouraged the diffusion of standard measures as a basis for open-door trade and international scientific partnership, they were also used—as the calorie was—to support agendas of autarkic and colonial development antagonistic to U.S. interests. ²⁹

Even as statistics became internationally standardized, their political uses grew more varied. Imperial regimes, independence movements, modernizing states, and new international agencies each validated their distinct hierarchies and ambitions in a numerical medium. The chief innovations of interwar diplomacy consisted in techniques of fixing calculable relations between powers: setting ratios of warships, quotas on immigration and trade, currency rates, and reparations payments. Despite the withdrawal into isolationism, the United States was closely identified with the movement to set quantitative norms. At the center of global finance and manufacturing, notes Emily Rosenberg, the United States emerged as a "leader in developing scientific and objective methods of organization and accounting." Nutritional science kept pace, devising an array of new and more precise metrics. By 1925, the British magazine The Spectator could observe that "the great American work of dietetics ... has won all along the line, despite vigorous resistance in this country ... [T]he idea of balance is becoming ever more insistent." ³⁰

European observers in the interwar years regarded enthusiasm for measurement and scientific regulation as both characteristically American and a grim portent of modernity's future course. To Dutch historian Johan Huizinga, the American penchant for reducing heterogeneity to numerical classifications represented a "Taylorism of the mind," a sacrifice of intellectual freedom to the dictates of efficiency. Used this way, science reached for sheltered and familiar terrain rather than the unknown. French novelist Georges Duhamel recognized that he had arrived at the "world of the future" when his American host urged him to order oatmeal rather than potatoes because "it will give you two hundred more calories." To Duhamel, the incident illustrated a distinctively American application of science as a palliative, and he reproached his hapless messmate for evading civilization's duty to confront uncertainty and disorder. "The word 'calorie' contains nothing to frighten me," he admonished. "I have lived in laboratories, but I think that laboratories and private life are two separate things ... Your faith in science doesn't bring you tranquility: it merely gives your uneasiness a different twist." ³¹

Still, quantitative nutrition obtruded into European life through the agency of governments and advertisers, although not always with the approval of the subjects of their interventions. Italian statisticians investigated the kitchens of peasants and fisherfolk. German factory managers posted calorie charts in workers' canteens. When Lord Shaw, presiding over a British commission of inquiry on the minimum wage, proposed a sliding scale based on calorie allowances, labor unions drew the line. Ernest Bevin, representing the National Transport Workers' Federation, protested that "it placed the worker as a distinct class on the basis of the animal, the basis of food alone, and that I would never discuss." But as Americans promoted "scientific" measures of opinion, consumer behavior, and efficiency abroad, they regarded the neutrality and clarity of their statistics as a gift to mankind. "Our latest symbol is not the big stick," the New York Times diplomatic correspondent wrote in 1929, "but the irrefutable and passionless yardstick." ³²

Ironically, the calorie's significance for nutritional science diminished while it gained official recognition as a measure of national vitality. Wartime rationing had fostered an international network of food experts and laboratories and pushed research in new directions. The isolation of minute compounds tied to specific diseases revolutionized the field in the 1920s. But while the "discovery of vitamins" discredited the notion of a single, definitive measure of food value, the calorie's application as a criterion of social hygiene proliferated globally, linked now to notions of competition and trusteeship. Elmer V. McCollum's laboratory at Johns Hopkins set international standards for measuring vitamins, minerals, and amino acids. These innovations rehabilitated the once-devalued oranges, cabbages, and cod, while reaffirming the importance of milk and wheat, now identified as "protective" foods vital to the growth of children. Balance remained the ideal, but in place of the calorie's double-entry bookkeeping, it now meant a distribution across a spreadsheet of five or more columns, an audit capable of identifying deficiencies by type as well as degree. By linking measurable substances to conditions such as pellagra, rickets, and beriberi, the "newer science of nutrition" achieved the clinical efficacy Atwater unsuccessfully sought. ³³

Crucially, it also revised the calorie's universalist premise, reintroducing a connection between diet and race. Where calories had ranked consumption on a unilinear scale of under- and over-nutrition, vitamins allowed classification of specific diets into categories of "malnutrition." A student of McCollum's, Lieutenant Colonel Robert McCarrison of the Indian Health Service, represented racial variations graphically in the form of trajectories, with the Indian races joined at birth in a common humanity but then arcing through time and consumption toward separate, nutritionally determined potentialities. In 1928, Victor G. Heiser, director of the Rockefeller Foundation's International Health Board, told the readers of Foreign Affairs that innovations in food measurement confirmed that physical differences identified as eugenic might in fact be nutritional, suggesting that "the races that first avail themselves of the new values of nutrition may decrease the handicaps of disease, lengthen their lives, and so become the leaders of the future." Nor was this purely an American apprehension. Allyre Chassevant, a nutritionist in the French military health service, warned that "the first nation which manages" the improvement of its popular diet "will create an incalculable national energy." ³⁴

No less than any other discipline, nutrition was subject to the moral ambivalence that afflicted modern science. Research that fostered international awareness of malnutrition and affirmed a universal entitlement to a healthy diet could simultaneously initiate a nutritional arms race or validate theories of racial dominion. Although the interwar years saw an intensified interest in food planning and the growth of an international network of nutritional institutes and specialists, the outlines of a unitary "food regime" did not appear until 1937. Instead, dietary research was conscripted into three conflicting agendas that can be labeled international, autarkic, and imperial development. Although each applied measurement as an administrative tool, they subordinated the caloric ideal of a fully optimized consumption to state or institutional goals, leaving Hoover's "continent" of human welfare unexplored.

Despite the defeat of Wilson's internationalist ideal by the U.S. Senate, officers of the new League of Nations aspired to create an organization that could address the root sources of international conflict by adjusting systems of labor, productivity, migration, and consumption. The first secretariat—led by Sir Eric Drummond, Jean Monnet, and, during the brief period before the Senate struck down the League treaty, an American, Raymond B. Fosdick—sought to "humanize" the Versailles system by displacing balance-of-power politics with "a systematic approach to international problems where everybody has everything to gain and nothing to lose." License for this "new technique" of international activism was contained in League articles 23 and 24, which authorized international commissions for disease prevention, opium control, transit, and weights and measures. ³⁵

Beginning in 1925, the League Health Organization and the International Labor Office (ILO), headed by Albert Thomas, initiated a series of national nutritional surveys based on the Atwater method. By 1935, the League had set a global dietary standard of 2,500 calories per day for a laboring adult. Like the eight-hour day advocated by the ILO, this represented an unenforced, unlegislated ideal, but it nonetheless set a benchmark for school lunch programs, famine relief, and wage comparisons around the world. Thomas advocated universal norms as a method of international institution building. The process of debating and fixing social standards threw "into relief the common ideal toward which we are all advancing" and established a common vocabulary for supranational governance. ³⁶

In Geneva, as Monnet later observed, the vision of an "organized peace" founded on integrated planning soon faded into familiar habits of diplomacy, but private philanthropies quickly seized upon the new style of international activism. The Carnegie Endowment and the Twentieth Century Fund promoted the diffusion of an American standard of living as a basis for amity. Fosdick, on leaving the League secretariat to take charge of the Rockefeller Foundation, noted that because of its measurability, food presented a unique vehicle for demonstrating the advantages of rationalization. "Through modern statistics we are able, in our generation, to get a complete picture of supply and demand in relation to the world's food," he explained. "What we need now is synthetic thinking, constructive brains, and a plan, laid down in world terms." ³⁷

One such plan came from James Lossing Buck, an American missionary who conducted the first caloric surveys in China. Reporting in 1930, he noted that dietetic and farming patterns in China were the reverse of those in the United States' own troubled system of agriculture; the "pressure of population" compelled peasants to practice an intensive agriculture that produced a larger ratio of calories per acre, chiefly in the form of grain. In the United States, a meat-based diet supported expansive farming patterns that used technology to compensate for inefficient land use. As land grew scarce, Buck predicted, Americans would grow and consume food more like the Chinese, and as China modernized, American technology would allow cultivators to eke more from their tiny plots. ³⁸

The theme of a natural partnership between American engineers and Chinese peasants reached a broad audience through Pearl Buck's 1931 bestseller The Good Earth. Buck's husband's tabulations outlined in broad terms an agenda for joint action: preserving China's food balance would ultimately require "some method of population control," but a short-range solution could be found in "more intensive methods of raising crops." The Rockefeller Foundation funded schemes to distribute farm machinery and improved seeds in central China until 1937, when the Japanese invasion interrupted the work. The foundation then transferred the research effort to Mexico, where it developed techniques that would return to Asia as the "green revolution" in the 1960s. A massive program of rural modernization and nation building, the green revolution is customarily explained as a response to the post–World War II population boom, but the project began before any demographic shift was evident. As Fosdick insisted, it sprang from the quantitative logic of the food inventory. ³⁹

A second food regime emerged alongside interwar trends toward national autarky. The narrowing pattern of international exchange, evident by the mid-1920s, deeply worried U.S. leaders. Protective tariffs imposed in Europe, Japan, and the colonies, and the formation of currency blocs in response to the Depression, cordoned the world into closed spheres, a nightmare for American free traders. But economic regimentation on such a scale could not have been imposed without the use of the calorie, which facilitated market manipulations, propaganda, and planning. In Italy, for example, the Instituto Centrale di Statistica (ISTAT) regularly issued caloric tables illustrating the steady improvement of the national diet under fascism. Measures to subsidize and supplement rations enjoyed support from labor unions as well as scientific and military officials who urged an orthogenetic program for enhancing racial quality and fitness for military service. ⁴⁰

While ancient Rome had ensured panem et circenses through a system of imperial tribute, Mussolini made food self-sufficiency the foundation of the New Rome. His Battle for Grain in 1925 aimed to achieve freedom from the "slavery" of imported bread by marshaling consumption and expanding wheat production. As governments in Europe, North America, and Argentina encouraged wheat cultivation on marginal lands, international grain prices plummeted, motivating further economic insulation. Following the invasion of Ethiopia, ISTAT investigated minimum metabolic requirements as a tool for predicting Italy's ability to survive a prolonged embargo. Increasingly, as Carol Helstosky has shown, national food controls designed to reform and enhance popular diets were employed instead to enforce military austerity. ⁴¹

Japan's dietary reform movement applied the calculative logic of nutritional science to reconcile the imperatives of autarky and preparations for war. In 1921, the newly established Imperial State Institute for Nutrition began research with a calorimeter manufactured in Boston. Comparing Atwater's factors with results from Tokyo policemen, tram motormen, barbers, and primary school teachers, chief investigator Hideo Takahira confirmed that Japanese subjects required calories and protein in the same amounts as their American counterparts, a revelation that overturned a system of military victualing based on distinctive local cuisines. In the 1920s, the imperial army and navy systematically reformed rations, adding "Western" recipes and "ingredients of poor quality" to raise caloric content while cutting costs. Changes such as the addition of more beef and pork and the incorporation of wheat in the form of noodles, breads, and fried batter (tempura) were designed to invigorate the troops and place them on a nutritional par with their prospective American and British adversaries. The government then popularized the new "national" cuisine among civilians through recipe books, magazines, and exhibitions. Dietary reform was part of a "food plan" that, in combination with a "population plan" involving resettlement to Manchuria, aimed to maintain "imperial self-sufficiency" in the home islands. ⁴²

Even when official regimentation was light, the translation of food into numbers had a substantial influence on "national" cuisines. The interwar decades marked the high point of the "textualization of the culinary realm," but cookbook authors were less interested in heirloom recipes than in conforming local tastes to a progressive, international standard, typically by enlarging the consumption of wheat. The cuisine globally recognized as Greek, for example, appeared first in the cookbooks of Nikolaos Tselementes in the interwar years. A chef in Parisian restaurants, Tselementes Europeanized moussaka and pastitsio by eliminating Anatolian yogurt, oils, and spices and introducing a floury Béchamel identical to a high-calorie "white sauce" that American nutritionists were pushing as a meat substitute. Jeffrey M. Pilcher has examined the diverse ways in which Mexico's revolutionary government sought to assimilate Mesoamericans into a revitalized nation by promoting "the Spanish language, the capitalist work ethic, and the cuisine of wheat." The practice of condensing national character into recipes predated the calorie by a hundred years, but numerical standards lent scientific authority to the process as well as to certain choices, associating wheat with a cosmopolitan, forward-looking identity, and local ingredients, such as yogurt and corn, with a vernacular past. One effect was to encourage mass consumption of wheat even as autarkic policies increasingly segregated the world market, a combination that would prove disastrous after October 1929. ⁴³

In the British Empire, and especially India, innovations in nutritional research contributed to a reformulation of the imperial project around a mission of development and welfare known as the dual mandate. The double impact of Wilson's Fourteen Points and the Russian Revolution made it imperative, according to Sir Keith Hancock, to lend "positive economic and social content to the philosophy of colonial trusteeship by affirming the need for minimum standards of nutrition, health, and education." The dual mandate also adjusted policy to the requirements of an emerging empire-wide consumer-goods economy. Continuous-process manufacturing required reliable outlets for the branded toiletries, household equipment, cereals, and canned goods issuing from assembly lines, and the colonies contained Britain's largest potential sales territory. Reimagining subject populations as customers opened new possibilities and goals for imperial development. ⁴⁴

The "discovery of colonial malnutrition," according to Michael Worboys, occurred when investigations suggested that an improved diet might enhance the labor efficiency and buying power of rural, colonial populations. Under the new paradigm, colonial officials viewed formerly tolerable rates of disease and mortality as "a heavy drag upon prosperity," while seeking to raise "the standard of life of the Indian countryside" as a stimulus to "demand for food, clothing, and every form of manufacture." Dietary statistics identified areas of deficiency and guided investment. Thus positioned, nutrition held the key to linked problems of public health, agricultural revitalization, and economic development, giving British officials a broad injunction to manage markets, irrigation, property rights, social services, and consumption in the name of the public welfare. ⁴⁵

As Mohandas Gandhi and other nationalists recognized, the crisis of malnutrition furnished an expansive justification for Britain's continuing stewardship, while nutritional science supplied a seemingly neutral, calculative language in which to reassert the claims of imperial ideology. In the course of their investigations, for example, nutritionists updated hoary distinctions between "martial" and sedentary races, classifying meat-, milk-, and wheat-eating peoples as physically efficient and prosperous owing to their superior diet. John Boyd Orr found that the "meat, milk, and blood" diet of Kenya's Masai produced a stronger physique than the vegetarian cuisine of the Kikuyu. McCarrison confirmed the "remarkable difference in physical efficiency of different Indian races" owing to variations in diet. The chief indicator of efficiency was the quantity of milk and the quality of grain consumed. European nutritionists uniformly disparaged rice, while dal, according to McCarrison, had a nutritive value so low as to be "toxic." These lessons were absorbed into the school curriculum, and Indian students were counseled that "rice is not very nourishing," while dal induced "paralysis of the legs." ⁴⁶

Challenges to these claims made dietary measurement a locus of nationalist resistance, which played out in two ways. The first was a move by subaltern critics to rehabilitate indigenous foods, particularly the devalued grains. Nishikanta Ray, a nutritionist at the University of Calcutta, praised rice as "the greatest of all cereals," and dal as richer in protein "pound for pound" than meat. Dudley Senanayake, who would later become the first prime minister of independent Sri Lanka, urged patriots to restore the "dignity" of rice and other native comestibles displaced by imperial commodities such as tea, sugar, and coffee. These critiques operated within the medium of nutritional science, affirming the necessity of hygienic measures to address malnutrition while challenging the colonial authority's accuracy, and consequently its jurisdiction over the embattled ground of social welfare. ⁴⁷

Gandhi, by contrast, premised his critique on the urgency of preventing modern science from gaining authority to set universal norms. Choosing diet as his point of attack, he challenged science's fundamental claims to realism. Dietetics, he acknowledged, introduced techniques "fraught with the greatest consequences for the world and especially for the famishing millions of India," but he rejected the validity of calculative methods—and by extension the universalistic claims of all expertise—advocating instead a descriptive, particularistic empiricism. He urged followers not to copy his own regimen of fruit, milk, and uncooked vegetables but to do their own experiments, insisting on the specificity of individual appetites and the distinct properties of each food. Satyagraha required a consciousness of diet attuned to the body, the community, and ahimsa, the principle of nonviolence. Since science abstracted food from the labor of growing, cooking, and digesting, Gandhi mingled his dietary advice with un-abstract discussions of urine, frying oils, mastication, the life cycles of plants, and techniques for kneading manure into the soil. Apart from caloric values, each vegetable and fruit possessed "physical and spiritual values" that could also be measured, but only in the unique laboratory of each human body. ⁴⁸

In crafting a link between diet and nationalism, Gandhi used food as a potent symbol of the value of the particular, the local, and the individual under assault from the homogenizing logic of modern science. As Ashis Nandy observes, Gandhi conceptualized development as an expression of personal morality and happiness, and disparaged the penchant of industrial civilization for "gauging progress in terms of calories and comforts." To accept the West's terms of reference, he contended, was to risk incorporation into a developmental regime in which singular cultural values would not count. ⁴⁹

The crisis of agriculture that followed the reverberations of the stock market crash around the world starkly exposed the inadequacy of food regulation on a purely national basis. As prices plummeted and stocks of grain and meat rotted in storage, militant farmers' unions in North America, Australia, and Europe demanded interventions to shore up prices, but restrictions that dumped milk and plowed under crops while urban laborers starved could scarcely be justified as rationalization. Trade ministries found that they could buttress agriculture only at the expense of manufacturing; protectionist controls hurt overall consumption, while subsidies, the solution eventually improvised in the United States, Australia, and Canada, led to the accumulation of enormous unused stockpiles. Sir William Haldane warned in 1933 that a glut of 350 million bushels of wheat was strangling all other markets, precluding the resuscitation of world trade. It was in these circumstances that a global scheme for disposing of surpluses in the statistically malnourished colonial and semicolonial areas took shape. ⁵⁰

The UN Food and Agriculture Organization (FAO) claims the 1936 report of the League commission on nutrition as its founding document. A compilation of research on nutritional requirements, dietetic surveys, and policy comparisons, it aroused an emotional response seemingly out of sync with its content. The Spectator found its findings "little short of revolutionary." The commission had laid bare, according to the New York Times, "the challenge underlying the disorders of this epoch, the pretext for modern wars." The power of the report's message was conveyed by a juxtaposition of three columns of data, all in calories, previously considered in separate contexts: figures on the minimum requirements for mothers and children, per capita consumption of food in various countries, and total volume of food produced. The tables illustrated ("irrefutably," according to commentators) a connection between the crisis of agricultural overproduction in some countries and the problem of malnutrition in others, a planetary imbalance requiring, according to Australian delegate Stanley Bruce, "a marriage of health to agriculture." ⁵¹

The report proposed a grand design for a "consumer economics" that would reconcile local autonomy and multilateral trade. Intensified national efforts at food self-sufficiency coupled with international food redistribution would spearhead a demand-driven expansion of global commerce. Advances in statistics, it concluded, made it possible to predict "the probable increase in demand which would follow on the adoption of an optimum regime of nutrition." The gains were potentially huge. Asia, for instance, could easily absorb all of North America's surplus stocks of milk and wheat. Moreover, the commission anticipated, transfers would provide a durable solution to instability. Since shortfalls were not episodic but chronic, food shipments would carve out permanent markets and channels of trade. "Generally speaking," the report found, "most Chinese are in a state of malnutrition all of the time." ⁵²

Britain's Parliament hailed the strategy as an indirect assault on economic nationalism. The United States, abandoning its customary detachment, lent it increasing support out of a conviction, articulated by Agriculture Secretary Henry Wallace, that the overproduction crisis could be solved only by optimizing consumption in low-income areas of Latin America and Asia through measures that presaged postwar foreign aid programs. When Henry Luce appealed for an "American Century" based on the dissemination of U.S. laws, the U.S. Constitution, and "magnificent industrial products," Wallace countered with a vision of a global consumer's century founded on technical aid and modern science, which "made it possible to see all of the people of the world get enough to eat." The construction of a postwar international order began with food. In 1943, the Roosevelt administration gathered seventy-seven nations to institute the first component of a new United Nations system, the FAO, with the mission of balancing mass production against the "mass buying power" of the world's farmers. By then, Franklin Roosevelt had declared freedom from want an American war aim, and Atwater's "food supply of the future" had become a political reality. ⁵³

Of the traces left by the calorie on the food regime that came into its own after the war, three merit particular attention for the magnitude and durability of their effects. The first was a recasting of hunger as an aggregate problem for which nations and international agencies bore primary responsibility. The FAO, incorporated into the new United Nations organization, cultivated a network of national food ministries and published annual "balance sheets" for each nation. Beginning with India's 1946 crisis, "famine" came to be understood as a national caloric deficit rather than the strictly localized emergency defined by imperial famine codes. Hoover, delegated to survey the scarcity in April 1946, reported levels of 800 calories a day in Austria and India, 1,000 in Germany. Caloric accounting reversed the flow of information about famine; international authorities decreed emergencies, while officials in stricken areas complied with mandated remedies. ⁵⁴

Secondly, the United States, as the leading exporter, recognized the value of grain shipments in fortifying clients against ideological assault. Hoover's remedy for Bolshevism became an axiom of national security. To General Lucius Clay, U.S. occupation governor in Germany, it was self-evident that offering a "choice between becoming a communist on 1500 calories and a believer in democracy on 1000 calories" would "pave the way to a Communist Europe." The China White Paper attributed the collapse of the nationalist regime to its "failure to provide China with enough to eat." Beginning in 1954, U.S. officials wielded transfers through Public Law 480, the Food for Peace program, as instruments of influence. In the atmosphere of the Cold War, quantitatively comparable food supplies
