For most of history, turning grain into edible food required hours of daily grinding, overwhelmingly done by women and servants, making the grindstone the central site of female drudgery. Industrial milling, canning, and mass-produced staples shifted that labor to machines and factories, so processed food functioned as a liberation technology rather than a degradation of some idyllic homemade past.
Laudan treats each cuisine as resting on an implicit philosophy linking food to health (such as humoral or cosmic balance theories), to the sacred (sacrifice, purity, fasting), and to the social order (who eats what by rank). Shifts in that philosophy, such as the move from humoral theory toward nutrition science, are among the forces she shows reshaping what people cook and eat.
Treating cooking as a set of techniques for transforming raw materials, like metallurgy, makes visible the labor, fuel, tools, and knowledge that a cuisine requires. From this angle, dishes spread because techniques and processing infrastructure spread, not because of timeless local authenticity or terroir.
Major culinary shifts track the expansion of states and universal religions, which carried standardized high cuisines, dietary rules, and crops across vast territories. Buddhist, Islamic, and Christian cuisines each became templates adopted by elites in conquered or converted regions, so the map of cuisines closely follows the map of political and religious power.
Through most of history, societies kept a split between an elite high cuisine of refined grains, meat, sugar, and elaborate sauces and a humble cuisine of coarse grain gruels with little variety for the majority. Modern middling cuisines are distinctive because they extend once-elite foods like white bread, meat, and sugar to far more people, broadening access without doing away with high and humble cuisines altogether.
The romantic ideal of fresh, local, handmade, traditional food rests on a false memory of the past, which for most people meant monotony, scarcity, adulteration, and spoilage. Rejecting industrial food as inauthentic ignores that modern processing delivered safer, cheaper, more varied, and more abundant food to the majority for the first time.
