In the early twentieth century, US writers looked at modern food—its global geographies, its nutritional theories, and its technological innovations—and saw not merely the incursion of industry and the threat of adulteration but an imaginative possibility. Fiction of the 1920s and 1930s represented food systems and used alimentary metaphors to unsettle the bases of racial classification and white supremacy. Dietetics played a key role in so-called race science, which blamed industrial food for Nordic degeneration and looked to euthenics, the study of nutrition and environment, to fix broken modern bodies that were insufficiently white. Thus, the dreams of new bodies and new categories expressed in this literature constituted a radical response to the political and nutritional theories of this cultural moment. For Jean Toomer and George Schuyler, both frustrated by the stigma of blackness in a segregated society, food technologies represented an opportunity to invent a new race or to renovate an old one. For F. Scott and Zelda Fitzgerald, Gertrude Stein, and Ernest Hemingway, enmeshment in the food system revealed that whiteness could not embody the purity that was supposedly its hallmark. In the Great Depression and thereafter, Zora Neale Hurston and Dorothy West indicted racist social structures and used food to interrogate the boundaries of the human. In a time of segregation, nativism, and Fascism, food brought bodies together and spoke of shared pleasure and vulnerability.
