Here's why you've never eaten a banana seed

Hank loves bananas and is worried about their future, so he did some investigating and wrote this four-minute episode of SciShow to share some kind of scary banana truths with us.

Why bananas are in trouble

The average American eats over 25 pounds of bananas every year, but we won't for long if a deadly soil fungus continues to spread. Learn what scientists are doing to save the popular fruit.

Dr. William Gorgas eradicated yellow fever in Panama, crucial to canal construction

The disease was one of the factors hampering the French effort to build the canal. Gorgas' experience elsewhere in the Caribbean had taught him that good drainage and quaranting patients were essential, and he would eventually apply mosquito prevention tactics on a mass scale.

The average banana produces one positron—the antimatter counterpart to an electron—every 75 minutes as its trace amounts of radioactive potassium decay.

Watermelons were once neither red nor sweet

The gargantuan summer picnic staple has a fascinating story: 100 million tons are produced worldwide and they take up the most space of any vegetable crop in the world. But not long ago, the flesh of the melon was white and it had a bitter taste.

The mystery of the cucumber, from coiling tendrils to its bitter, mature fruit

Cucumus sativus was first cultivated 3,000 years ago in the Himalaya of India, appearing in ancient Sanskrit hymns in the Hindu tradition. They are typically harvested well before maturation, as their yellow, final fruit is bitter. Their coiling tendrils were so distinct they prompted famed naturalist Charles Darwin to publish one of his lesser-known works, "On the Movements and Habits of Climbing Plants." Its refreshing coolness inspired cucumber-derived body washes and sprays over millennia.

'Johnny Appleseed' was the itinerant horticulturalist John Chapman

Born in 1774 in Massachusetts, Chapman planted apple orchards for pioneers across Pennsylvania, Ohio, and Indiana, to be sold to locals to produce hard cider. He became famous through a 'Harper's Weekly' profile in the late 1800s, cultivating the modern legend.

The birth of the multivitamin

In 1912, biochemist Kazimierz Funk, often anglicized as Casimir Funk, proposed that there existed an essential nutrient in food that could prevent deficiency diseases, such as scurvy or rickets. This article explores the origin of the multivitamin, an invention that has garnished...

He made a name with a short story about jumping frogs

Twain’s first big break came with “Jim Smiley and His Jumping Frog,” a fictitious story that appeared in a 1865 edition of the New York Saturday Press. (When it was republished elsewhere, the title was changed to “The Celebrated Jumping Frog of Calaveras County.”) That year, American poet James Russell Lowe called it “the finest piece of humorous literature yet produced in America.”

Health food broke into the mainstream by the 1980s

A 1984 New York Times story noted that Americans were eating less red meat than a decade prior, and that, in general, the country was “talking, thinking and worrying about what they eat to a degree unique in the nation's history.” The feature then details foods that were then considered bizarre: whole-grain muffins, hummus, and a variety of vegetarian dishes. (Some readers may experience a paywall.)

'Diet for a Small Planet' popularized the vegetarian diet

Frances Moore Lappe’s 1971 book provided recipes for vegetarian dishes, introducing millions to soy, sprouts, and tofu. It also argued that a vegetarian diet was a political act that could solve world hunger by redirecting food from livestock to humans.

In 1842, a 'mermaid' from Fiji was put on display at a museum, drawing large crowds and fooling many. It was later discovered that the creature was created by sewing the upper body of a monkey to the lower body of a fish.

Why pickles became a thing

Pickles began in Mesopotamia around 2400 BCE as a way to preserve vegetables amid heat (and spoilage). They spread through Egypt, Greece, and Rome, where Julius Caesar reportedly fed pickles to his soldiers, and brining was treated as a culinary art. The technique is broadly useful, as salt and water can extend the shelf life and deepen flavor for almost anything.

'Vacation' wasn't common for Americans until the mid-1800s, when it became a luxury for the wealthy.

A French Army surgeon discovered that malaria is a parasitic disease in 1880—but scientists were initially skeptical.

Bill Bowerman brought running for fitness to America

Nike cofounder Bill Bowerman once cowrote a book with a doctor, W.E. Harris, called “Jogging.” Published in 1967 by New York, Grosset & Dunlap, it introduced America to the idea of running for health, instead of just sport—and kicked off the fitness frenzy of the 1970s that fueled Nike’s early success. (Some readers may experience a paywall).

Belgian waffles were originally called 'Brussels waffles,' but the name was changed because a vendor believed most Americans were not familiar with the country's capital city.

Cholera went global thanks to global trade

The first cholera pandemic grew from an outbreak in India, in 1817. Scientists suggest it spread from there throughout the continent and onward to Africa, Russia and Europe through the poop of traders.

Lewis and Clark identified 122 animal species new to science.

The earliest mention of time travel

Time travel has fascinated humans for centuries. It appears in myths, literature, and science fiction. One of the earliest examples comes from the 400 BCE Hindu epic Mahabharata, describing time dilation long before Einstein’s Theory of Relativity. By the 19th century, stories introduced machines enabling time travel—setting the stage for modern sci-fi.

Candide's 'Voltaire' satirized blind optimism

The French philosopher's most famous work, published in 1759, cataloged the journey of its titular hero, who was guided by a crackpot philosopher and the belief that optimism was the solution to life's problems, despite all the evidence to the contrary.

Thomas Cook invented modern tourism in the 19th century by creating package tours and travel guides for aspiring travelers.

Once considered a fringe activity, running eventually became an American interest. The trend was spurred in part by the 1966 book "Jogging," which was cowritten by Bill Bowerman, the cofounder of Nike.

American farmers—including George Washington—experimented with coffee farming

Two coffee plants—an arabica strand and a Kentucky Coffee Tree—continue to grow at Mount Vernon, Washington's iconic Virginia home. The Marquis de Lafayette requested the agrarian commander send him some beans in France.

Hamilton learned about global trade before he was a teenager

Before he moved to America, Hamilton worked as a clerk around age 12 at the Caribbean trading firm Beekman and Cruger, handling shipping documents, inspections, and port logistics. He eventually managed the day-to-day operations of a trading charter that immersed him early in Atlantic commerce.

The Hawaiian pizza was popularized by a Canadian chef

Hawaii's tiki culture was popular in North America through the mid-20th century, with canned pineapple a household staple. Sam Panopoulos, a Greek immigrant who operated a diner in Ontario, experimented with outlandish pizza recipes until he stumbled upon the idea for topping a pie with canned pineapple and ham.

Why did the US make it illegal to sell sliced bread during WWII?

Pre-sliced bread has only been with us for almost 100 years, but during the course of World War II it was briefly banned to save on supplies like wax paper and stainless steel for the war effort. This Atlas Obscura article explores this amusing (though not at the time) bit of food during wartime history.

Unlike fruits, the category of 'vegetables' is a culinary term, not a scientific one

Within botany, fruits are defined as the ripened ovaries of flowering plants, and include apples, grapes, tomatoes, avocados, green beans, peppers, and almonds. In the kitchen, "vegetables" is an umbrella term that encompasses many fruits and other parts of plants, such as leaves (lettuce, kale) and roots (carrots, beets).

Lewis Carroll's 'Alice's Adventures in Wonderland' turned the fantasy genre upside down
