When People Thought Tomatoes Were Poisonous

People thought tomatoes were poisonous for a fascinating and surprisingly long time.

Imagine a world where this vibrant, juicy fruit, now a staple in cuisines worldwide, was viewed with suspicion and fear.

This era of culinary mistrust isn’t just a historical footnote; it’s a compelling story of misunderstanding, botany, and social class.

For centuries, Europeans, particularly the elite, approached the tomato with extreme caution. It was a plant of intrigue, known for its beauty but not for its edibility.

They admired its ornamental qualities, growing it in gardens alongside flowers, a testament to its visual appeal rather than its use in the kitchen.

The fear surrounding the tomato stemmed from a simple botanical mix-up. The plant belongs to the nightshade family, Solanaceae, which includes many toxic species.

This family also contains deadly nightshade, Atropa belladonna, a plant infamous for its poisonous berries.

It’s a classic case of guilt by association. The tomato’s innocent leaves and stems contain small amounts of alkaloids, a group of chemicals also found in its more sinister relatives.

This shared lineage was enough to cast a shadow of doubt over the entire plant, making it a forbidden fruit for the cautious consumer.

The wealthy were particularly susceptible to this belief. They used pewter plates, which were high in lead.

When acidic foods like tomatoes were placed on these plates, the lead would leach out, causing lead poisoning.

Symptoms of lead poisoning, such as stomach pain and death, were then incorrectly attributed to the tomato itself.

The poor, who ate off wooden plates, didn’t experience this issue, and they were the first to embrace the fruit, a stark contrast to the elite’s unfounded fears.

A Global Journey of Mistrust

From Italy’s Love to American Loathing

While the tomato was viewed with suspicion in much of Europe, it found a foothold in Italy and Spain.

The warmer climates were ideal for cultivation, and the people of these regions began incorporating it into their diets.

Its integration into Italian cuisine, in particular, created the foundation for some of the world’s most beloved dishes.

However, the tomato’s reputation struggled to cross the Atlantic. In North America, the general consensus was that it was a poisonous plant, an attitude that persisted well into the 19th century.

A widely cited but apocryphal story tells of Colonel Robert Gibbon Johnson, who, in 1820, ate a basket of tomatoes on the steps of the Salem, New Jersey courthouse to prove their safety.

This public stunt, though likely exaggerated, captures the cultural skepticism of the time.

The very idea of someone risking their life to eat a tomato shows just how entrenched the belief was that the fruit was deadly.

It took brave acts and a slow shift in public opinion to overcome this deeply rooted fear.

The tomato’s redemption was a gradual process. The culinary revolution of the late 19th and early 20th centuries, combined with increased global trade, helped to normalize the fruit.

As more people were exposed to it in different forms—sauces, soups, and salads—the old fears began to fade.

Consider the simple, elegant power of a tomato sauce. Its ability to transform a dish is undeniable, yet for many generations, this transformative power was hidden by an unfounded fear.

Overcoming the Poisonous Perception

The Scientific and Cultural Shift

The eventual widespread acceptance of the tomato was a confluence of factors, including botanical knowledge and culinary innovation.

As scientists better understood the plant’s properties, the link to deadly nightshade became less of a deterrent. The focus shifted from its family tree to its nutritional benefits and flavor.

++The Story of Tarrare: The Man Who Could Eat Anything

Today, the tomato is one of the most widely consumed fruits globally.

According to the Food and Agriculture Organization of the United Nations (FAO), global tomato production in 2023 was estimated at over 190 million metric tons.

This immense production volume demonstrates just how far the tomato has come since the days of suspicion.

The story of the tomato is a powerful analogy for how unfounded fears can become deeply ingrained in society.

Like a rumor that spreads faster than the truth, the myth of the poisonous tomato persisted for centuries. Its eventual debunking highlights the triumph of curiosity and scientific inquiry over inherited prejudice.

So, the next time you enjoy a slice of pizza or a fresh salad, pause for a moment to consider the incredible journey of the main ingredient.

It’s a fruit that was once an outcast, an ornamental plant feared by the wealthy. The very idea that people thought tomatoes were poisonous seems absurd today, doesn’t it?
