There is a difference between knowledge and wisdom.
Knowledge is knowing that a tomato is a fruit not a vegetable.
Wisdom is knowing not to include it in a fruit salad.
The deep roots of the tomato: From wild Andes to global table
The wild ancestor of the modern tomato (Solanum lycopersicum) originated in the high-altitude valleys of the Andes mountain range, spanning modern-day Peru, Ecuador and Chile. Long before European contact, indigenous peoples—particularly the Aztecs and Incas in Mesoamerica—domesticated and cultivated the plant as early as 500 BCE, transforming small, wild berries into plump, nourishing food that became a cornerstone of ancient American cuisine.
When tomatoes were first brought to Europe from the Americas in the 16th century, botanists classified them within the nightshade family. Relying on their technical knowledge of toxic European plants like belladonna, experts declared the fruit poisonous, leading Europeans to grow them purely as ornamental garden novelties for centuries without ever eating them.
It required practical experience and traditional wisdom from Central and South America to recognise that despite belonging to a risky botanical family, the ripe fruit was entirely safe and edible. This distinction between scientific taxonomy and everyday reality eventually culminated in a fascinating legal showdown.
In the 1893 case of Nix v. Hedden, the United States Supreme Court had to rule whether tomatoes were legally fruits or vegetables for tariff purposes. Using practical common sense, the Court concluded that while a tomato is scientifically a fruit, at the dinner table and in the marketplace it is handled strictly as a vegetable.
Following Spanish colonisation of the Americas, the tomato embarked on a global voyage facilitated by maritime trade routes, spreading rapidly across the globe. Spanish and Portuguese traders carried the seeds from the New World across the Atlantic to Europe and across the Pacific to Southeast Asia, where it quickly integrated into Mediterranean, Middle Eastern, and Asian cuisines, transforming from an exotic American curiosity into a universal culinary staple.
