The grains that built empires—and the fungus that fueled hallucinations

Every Grain Explained · 13:09 · Video: Food Explained · Watch at the source

In short: From wild grasses to global staples, our pantry is a map of human history. This video explores how 12 specific grains shaped civilizations, sparked pandemics, and survived colonial attempts at erasure.

The narrative moves beyond simple nutrition to explore the profound agricultural engineering behind modern food. It covers why modern wheat can no longer survive in the wild without human intervention and the unique cultivation of rice in flooded fields. The video also investigates historical impacts, such as how beer may have kick-started farming and a medieval fungus on rye that caused mass hallucinations.

The exploration includes the evolution of corn from finger-sized grass to America's most farmed crop, alongside the survival of staple foods against colonial erasure. It highlights ancient grains like spelt and quinoa as potential 21st-century climate solutions while distinguishing wholegrains—which retain the bran, endosperm, and nutrient-rich germ—from refined versions that strip away vital fiber and polyphenols.
