This humble, mostly-water tuber was once the mainstay of New York's futures exchange, and in 1976 caused a record default.

Where it comes from

Chart: Map of where it comes from

Potatoes grow from certified seed tubers in cool, loose soils, yielding more food per hectare than most cereals; the world grew about 390 million tonnes in 2024.

Three things to know
  1. World potato output climbed from 267 million tonnes in 1990 to about 390 million in 2024, with China and India growing nearly two-fifths.
  2. Potatoes are 78-80% water, so they are costly to ship; only about $6.2 billion of fresh potatoes crossed borders in 2023.
  3. For fries and crisps, high dry matter and low sugars matter most, giving crisp, light-coloured products and less acrylamide.
