Slide 1
Atlantic contact moved living things
After 1492, sustained connections across the Atlantic accelerated transfers of plants, animals and pathogens. Historians call these linked changes the Columbian Exchange.

The term describes a long process rather than a single transaction between equal partners. Colonization and forced labour shaped many of the transfers. Following an ingredient’s journey therefore involves political relationships as well as a line on a map.
Slide 2
American crops travelled widely
Maize, potatoes, tomatoes and chilli peppers originated in the Americas. Their later spread helped reshape diets in parts of Europe, Africa and Asia.

Origin and cultural identity are different questions. A crop can become central to a regional cuisine long after arriving from elsewhere. Studying adoption reveals the work of farmers and cooks who incorporated unfamiliar ingredients into local practices.
Slide 3
Crops travelled in both directions
Wheat and sugar cane were among the crops brought to the Americas from across the Atlantic. Introduced animals also changed agriculture and surrounding landscapes.

A new crop’s effects depend on how it is produced. A household garden and an export plantation can grow within the same wider exchange while creating very different labour demands and land relationships. The plant alone does not determine the social result.
Slide 4
Arrival did not mean instant adoption
A crop’s movement to a new region was only the beginning.
Climate, cultivation methods, preferences and access to planting material influenced whether people made it part of their lives.

A useful historical sequence separates first arrival, experimental cultivation and widespread use. Those stages may be far apart. Finding an early mention of a plant does not establish that it immediately became a staple across the surrounding population.
Slide 5
A food history can reveal global links
Tracing familiar ingredients makes long-distance historical connections visible.
The resulting diets reflect accumulated choices made under changing conditions of trade, empire and local life.
More to Read
A recipe can be treated as evidence of connections, but its modern form cannot simply be projected into an earlier century. Dating particular ingredients and uses helps reconstruct change without assuming that a familiar tradition has always existed unchanged.
