Why the Delicious Potato Was Once Feared

Weird. Weird. And Even Weirder!

Potatoes have one of the wildest journeys in food history. For centuries, people genuinely thought they were toxic. Here’s how the humble spud went from feared plant to global staple.

Humans really should not be able to eat potatoes. Everybody loves a fresh batch of those golden fries. But we are incredibly lucky that potatoes even exist in a form we can eat. The ancestors of potatoes didn’t really grow starchy bulbs at all. They picked up that ability through a genetic swap with tomatoes. Those early tubers were toxic because potatoes belong to the nightshade family. But indigenous communities in South America figured out how to breed the poison out of them slowly and deliberately over hundreds of years.

From the Andes to Europe: A Suspicious Arrival

Potatoes were first domesticated around 8,000 years ago in the Andes (modern Peru and Bolivia). Indigenous communities not only ate them safely, but they also figured out how to freeze-dry potatoes into chuño, making them last for years.

Trouble started when Spanish explorers brought potatoes to Europe in the 16th century.

Why Europeans were freaked out, some even blamed potatoes for leprosy, plague, and general moral decay because: 

• Potatoes belong to the nightshade family, which includes deadly plants like belladonna
• The leaves, stems, and green potatoes contain solanine, a real toxin
• Potatoes grow underground, which made people suspicious (if it’s not touched by the sun, can it be trusted?)

Potato Phobia – Real or Unfounded?

But when potatoes finally reached Europe in the 1500s, people didn’t trust them at all. Some rejected them for religious reasons. At the time, one agronomist even wrote that people were suspicious because potatoes weren’t mentioned in the Bible. Also, because it’s a history of toxicity and inedibility.

Aristocratic Frenchman Antoine-Augustin Parmentier began hosting potato banquets for the elite to convince people that they were safe to eat. But here is the strangest part. Even after genetic accidents, centuries of careful breeding and cultural resistance. The fact that you can simply eat a single French fry is kind of a miracle.

The Science that Made Potatoes “Safe”  

What we take for granted today wasn’t always the case. And that’s where science stepped in to develop a worldwide superstar.

Potatoes are safe when:

• Cooked (boiling, baking, frying reduce solanine)
• Stored in the dark (prevents greening)
• Eaten as the tuber only (never the leaves or stems)

However, the toxins never disappeared — we just learned how to manage them.

Crispy Roast Potatoes

Ingredients:

• 6 potatoes, peeled and cut into quarters
• ½ cup olive oil
• Salt, to taste
• Freshly ground black pepper, to taste

Instructions:

1. Parboil the potatoes until just tender but still firm. Drain well and refrigerate until completely cool.
2. Preheat the oven to 450°F (230°C). Add the olive oil to a shallow baking dish and place it in the oven for a few minutes until hot.
3. Carefully add the cooled potatoes to the hot oil, turning to coat evenly.
4. Roast for about 1 hour, turning once or twice, until deeply golden and crispy.
5. Transfer to paper towels to drain excess oil. Season with salt and pepper and serve immediately.

From Survival Food to Comfort Icon

By the 19th century, potatoes were central to European diets. They fueled population growth, urbanization, and entire cuisines—until reliance became excessive during the Irish Potato Famine.

Today, potatoes are the third most important food crop in the world, behind rice and wheat, and appear everywhere from haute cuisine to fast food. 

Thank heavens, caveat emptor (buyer beware) no longer applies! So enjoy them with mustard, mayo, ketchup, salt, butter or simply on their own.
