Why Food Matters

Food is never just fuel.
It is identity, memory, and politics on a plate.
A family’s recipe is an archive of migration and adaptation; a supermarket shelf maps global power relations.

Anthropologist Sidney Mintz (1985) traced how sugar transformed from a colonial luxury to a daily necessity, linking the diets of European consumers to enslaved labor in the Caribbean. Through food, we literally taste history: each bite carries the fingerprints of empires, technologies, and markets.

Today, globalization makes our meals planetary. A breakfast of coffee, bananas, and toast involves farmers in Ethiopia, plantations in Ecuador, and wheat fields in Kansas.
The kitchen has become a microcosm of international relations whether you realize it or not!

Read on for a superspeed overview of the evolution of food through the ages. Each of these subections can be its own book, but for our purposes, a quick overview will get our creatives juices flowing and maybe leave you hungry for more. (Pun intended!)

The Agricultural Revolution to the Age of Empires

The Neolithic Foundation

About 10 000 years ago, humans shifted from foraging to farming—a transformation known as the Agricultural Revolution.
Domestication of wheat in Mesopotamia, rice in the Yangtze basin, and maize in Mesoamerica launched civilizations (Diamond, 1997).
Agriculture created surpluses, enabling cities, states, and hierarchies.

Yet early farming also brought inequality and disease.
Sedentary life meant nutritional monotony—fewer wild foods, more grains—and closer contact with pathogens carried by domesticated animals.
In a sense, health crises have accompanied agriculture from its birth.

Spices, Silk, and the First Global Food Trade

By 200 BCE, the Silk Road connected Asia, Africa, and Europe.
Spices such as cinnamon and pepper were worth more than gold, shaping entire economies (Freedman, 2008).
Medieval travelers like Ibn Battuta and Marco Polo recorded diverse cuisines and food rituals, revealing early cultural globalization.

This exchange also spread crops:

• Sugarcane from India reached the Mediterranean.

• Citrus fruits moved east to west.

• Rice cultivation spread from China to Africa.

The Columbian Exchange

After 1492, the world’s ecosystems and diets were radically rearranged. Alfred Crosby (1972) coined the term Columbian Exchange for the massive transfer of crops, animals, and diseases between the Old and New Worlds. Potatoes and maize fed Europe and Asia; wheat and cattle remade the Americas. But the exchange also unleashed epidemics and exploitation, indigenous populations were decimated, and African enslaved labor became the engine of plantation economies.

The first taste of globalization was both nourishing and deadly.

Colonialism, Capitalism, and the Industrial Food Chain

Sugar, Slavery, and Capital Accumulation

By the 18th century, sugar plantations in the Caribbean and Brazil symbolized the merging of agriculture, slavery, and finance.
Plantations were early factories, monocultures powered by human bondage.  As Eric Williams (1944) argued in Capitalism and Slavery, profits from slave labor fueled Europe’s industrial revolution. Food commodities were central to empire-building: coffee in Java, tea in India, cocoa in Ghana, rubber in Malaysia. Colonial diets reinforced hierarchies. European elites dined on imported delicacies while colonized peoples faced forced cash cropping and malnutrition (Patel & Moore, 2017).

The Green Revolution and the Rise of Agribusiness

Fast forward to the mid-20th century. After World War II, fears of famine spurred investment in agricultural science. The Green Revolution led by scientists like Norman Borlaug introduced high-yield crops, chemical fertilizers, and irrigation systems. Countries such as India and Mexico increased food production dramatically, but at ecological cost: soil degradation, groundwater depletion, and dependence on imported inputs (Shiva, 1991). Multinational corporations such as Monsanto (now Bayer), Cargill, and Nestlé expanded globally, consolidating control over seeds, fertilizers, and supply chains. Agriculture became agribusiness: a system where profit often outweighs nutrition or sustainability.

Globalization and the Modern Food Web

The WTO and Food Trade Liberalization

The 1995 creation of the World Trade Organization (WTO) integrated agriculture into global trade rules through the Agreement on Agriculture (AoA).
Proponents claimed liberalization would increase efficiency and lower prices; critics warned it would expose small farmers to volatile markets (Clapp, 2016).

Subsidies in the Global North—especially for U.S. corn and EU dairy—distorted competition, undercutting producers in Africa and Asia.
For example, West African cotton farmers struggle against U.S. subsidies exceeding $4 billion annually (Oxfam, 2011).
Thus, free trade in food often reproduces unfree conditions.

Global Supply Chains and the “McDonaldization” of Diets

Sociologist George Ritzer (1993) used the term McDonaldization to describe how efficiency, predictability, and control dominate global culture.
In food, this manifests as standardized menus, ultra-processed products, and uniform branding.
From Cairo to Seoul, global fast-food chains adapt local flavors while spreading Western consumption patterns.

This culinary homogenization erodes biodiversity: out of 6 000 plants once cultivated for food, only nine supply 66 percent of global crop production (FAO, 2021).
It also alters taste and health, as sugary beverages and high-fat snacks replace traditional diets.

Cultural Hybridization and Resistance

Yet globalization also sparks creativity. Korean tacos in Los Angeles, Peruvian-Japanese nikkei cuisine, and Senegalese thieboudienne in Paris exemplify cultural fusion.
Food becomes a language of cosmopolitan identity.

Meanwhile, local food movements—Slow Food in Italy, Farm to Table in California, Locavore activism in Japan—challenge industrial uniformity.
They reclaim pleasure and place, asserting that taste can be political (Petrini, 2001).

Institutions and Governance of the Global Food System

The FAO, WHO, and the UN System

The Food and Agriculture Organization (FAO), founded in 1945, coordinates efforts to end hunger and improve rural livelihoods.
The World Health Organization (WHO) addresses nutrition and food safety, while the World Food Programme (WFP) provides emergency aid.
Together, they anchor the UN’s Sustainable Development Goal 2: Zero Hunger. Despite progress, around 735 million people still experience chronic undernourishment (FAO, IFAD, UNICEF, WFP & WHO, 2023). COVID-19, climate shocks, and wars (notably in Ukraine) have disrupted supply chains, showing how fragile global food security remains.

Private Power and Public Responsibility

Beyond states, corporations and philanthropic foundations wield immense influence.
The Gates Foundation funds biotechnology initiatives; the World Economic Forum promotes public-private partnerships in agriculture. Critics argue that such “multi-stakeholder” governance blurs accountability and privileges corporate agendas over farmers’ rights (McKeon, 2017). Civil-society coalitions such as La Vía Campesina, representing 200 million small-scale farmers advocate food sovereignty: the right of peoples to define their own food systems. In 2018, the UN adopted the Declaration on the Rights of Peasants and Other People Working in Rural Areas (UNDROP), marking a normative shift toward justice and autonomy.

Food as Culture, Religion, and Identity

Sacred and Symbolic Diets

Every culture embeds values in what it eats and avoids. Hindu vegetarianism, Islamic halal, Jewish kosher, and Buddhist compassion toward animals express moral cosmologies. Christian fasting rituals and Indigenous harvest festivals link spirituality to sustenance. Food taboos often encode ecological wisdom: societies limit consumption of scarce species or align diets with seasonal availability (Harris, 1985). In modern times, ethical veganism extends this moral logic globally, merging compassion with climate activism.

Migration and Diaspora Cuisines

Diasporic communities preserve and transform food traditions abroad. Chinese takeouts, Mexican taquerías, and Ethiopian cafés in Western cities reflect both adaptation and resistance. For migrants, cooking becomes a way to “taste home,” maintaining identity amid displacement (Heldke, 2003). Food also mediates power: colonial and immigrant cuisines have long been exoticized or appropriated by elites, raising debates about culinary colonialism and cultural authenticity (Ray, 2016). It also raises questions about why we often believe "ethnic" food should be cheap - and western or European foods are elevated both price and in status. Why are we so happy to spend hundreds of dollars at a French restaurant but expect Chinese food to be cheap?  

The Health Transition: From Scarcity to Excess

The global food system now delivers both hunger and obesity. Low-income nations face a “double burden” of malnutrition: undernutrition coexisting with rising non-communicable diseases like diabetes and hypertension (Popkin et al., 2020).  Processed foods high in sugar, salt, and fats marketed aggressively by multinational corporations reshape health worldwide.  Ultra-processed products now account for more than half of calories consumed in high-income countries and are rapidly growing in middle-income ones (Monteiro et al., 2019). Do you ever wonder why there is less visible obesity in Europe historically?  This comes in part from much higher standards of nutrition in the European Union in terms of allowing processed foods on the shelf. For example, popular cereals allowed in the US are altered to leave out harmful dyes and high sugars. In Mexico as another example, foods that are high in fat or sugar, come with a large sticker saying that they are high in fats and sugars making the consumer think twice about eating that item. Or in the case of the many of the Pacific Islands, Spam and other processed meats and items were what was available during military occupation cementing poor nutirtional content into cultural heretage once other natural foods were no longer available or affordable. Food deserts in the US also mirror the same fates. If the only you food you have access too is unhealthy, the system is stacked against you. 

This transition signals that nutrition is political. Advertising, pricing, and urban planning determine what choices are available.  As activist Michael Pollan (2008) puts it, “Eat food. Not too much. Mostly plants”—a deceptively simple manifesto for a complex world.
