Imagine…

Italian pasta without tomatoes. Indian curry without chilies. Irish stews without potatoes.

Can you? None of these iconic indigenous foods existed before 1492.

People of the Americas spent thousands of years perfecting these foods. Crops like these would spark revolutions, end famines, and build empires.

Let’s take a look at the enormous contributions indigenous Americans made worldwide over the centuries.

1. The Crop That Built Civilizations

Maize was everything. The Maya considered it sacred. According to their beliefs, humans were literally made from corn dough. The gods tried many times to create humans. First from mud, way too soft, then wood. Finally, they ground white and yellow corn into dough, mixed it with water, and shaped humanity. This version worked. Humans could think, speak, and worship the gods. For the Maya, corn was sacred because they believed they were corn. Every tortilla was both food and communion. The Popol Vuh, the Maya’s holy text, calls humans “the people of corn.” Still today, many indigenous communities in Central America identify themselves as “corn people.

Today, this indigenous staple appears in over 4,000 products, from your morning cereal to the fuel in your car. Without it, there’s no bourbon, no popcorn at the movies, and no industrial food system as we know it.

2. The Tuber That Saved Europe

Way up in the Andes, indigenous farmers developed thousands of potato varieties. The Chuño, a freeze-dried version, would last for years. This method is one of humanity’s earliest forms of food preservation. Once potatoes reached Europe, they completely changed the dynamics of civilization. Ireland’s population doubled when potatoes arrived in the late 1500s. Unlike grain, potatoes could grow in poor soil and provide complete nutrition.

A huge tragedy! When the potato blight hit in 1845, it destroyed the only food source for millions of people. Until this day, the population hasn’t recovered. Ireland has roughly the same population as it did in the 1840s.

3. A Sacred Ritual Becomes A Global Obsession

Cacao beans were currency for the Aztecs. A rabbit costs 10 beans, and a tamale costs one bean. A “hired” companion went for 8-10 beans (Wow!) Due to their value, beans were often counterfeited by emptying the shells and filling them with dirt.

Mixed with chili peppers, vanilla, and even ground corn, Aztecs drank the bitter drink at royal ceremonies. Frothy Xocolātl (now “chocolate”) was reserved only for warriors, nobility, and religious rituals. Commoners rarely tasted it. Montezuma allegedly drank 50 cups a day from golden goblets.

Spanish conquistadors hated it! Too bitter, too weird! But wait, add sugar, the other colonial commodity. Suddenly, Europe was obsessed.

Today, chocolate is a $130+ billion global industry. The sacred Aztec beverage is now candy bars, hot cocoa, artisan truffles, and birthday cake. The beans that once paid for rabbits in Tenochtitlan now fuel Halloween and Valentine’s Day.

Want to try a DIY ancient Xocolātl ceremony at home? Here are a few items you will need for the whole experience: Mexican-style cacao tablets, traditional artisan cacao cups, and a molinillo to froth up that drink.

4. The Spicy Heat That Conquered Asia

Before 1492, “Spicy” foods were nowhere to be found in Asia, Europe, or Africa as we know them. Sure, Black pepper existed! But the heat that defines Thai curries, Indian vindaloo, Sichuan hot pot, and Korean kimchi? Indigenous people provided chili peppers, which were exclusively grown in the Americas.

For over 6,000 years, Mexicans have cultivated chilies, developing incredible varieties from mild poblanos to smoky chipotles, fruity habaneros, and tiny superhot tepins. More than just cooking, they were breeding, experimenting, and perfecting dozens of varieties.

The Portuguese and Spanish colonized the Americas and carried chili seeds along their trade routes to Asia in the early 1500s.

All it took was one generation to make chilies so integral to Asian cuisines that people assumed they’d always been there. By the 1600s, Koreans were fermenting gochugaru (chili flakes) into kimchi. Indians were grinding chilies into curry pastes. Thai cooks were tossing bird’s eye chilies into everything. Now you know the rest of the story. Yet, many people today think of chili peppers as “authentically Asian”.

5. The Feared Fruit

Indigenous peoples in Mexico and Peru had been eating tomatoes for centuries. The Aztecs called them tomatl and used them in salsas and stews. Not much has changed in Mexico.

But tomatoes terrified everyone when they arrived in Europe in the 1500s. Wealthy Europeans who ate tomatoes off pewter plates often got lead poisoning. The acidic tomatoes leached lead from the plates. People then thought the fruit itself was deadly. For 200 years, Europeans grew tomatoes as ornamental plants, calling them “poison apples.”

Enter the brave Southern Italians. Poor farmers in Naples ate them in the late 1600s and early 1700s. Possibly because they were desperate and hungry. Nobody died, so tomatoes caught on fast. Neapolitans were simmering tomato sauce, and by the 1880s, they’d invented pizza Margherita. I am thankful for their courage and for their arrabiata pasta sauce.

The transformation was complete: Tomatoes became the defining ingredient of Italian cooking. They rewrote the Italian identity. Pasta pomodoro. Caprese salad. Bruschetta. Pizza. All of it was invented after a Mexican fruit finally convinced Italians it wouldn’t kill them. Indigenous Americans had been eating tomatoes for 2,000 years. No complaining that “pizza” is not American.

The Ripple Effect

We have to thank the Indigenous Americans for adding variety to our diets and preventing mass starvation. These foods sparked economic booms and even influenced geopolitics. Potatoes fueled Europe’s Industrial Revolution by feeding factory workers. Tomatoes created Italian immigrant cuisine in America. Corn subsidies shaped U.S. agricultural policy for a century.

Next time you sip hot chocolate or eat spicy Kimchi, you’re not just snacking. You’re participating in a 10,000-year-old agricultural legacy.

The indigenous peoples of the Americas didn’t just feed themselves. They fed the world.
