Is a Tomato a Fruit?

It's been called a super food, a functional food, and just plain delicious. It's the tomato, and it has an abundance of vitamins and nutrients that help keep our bodies moving, from lycopene (which may help ward off some chronic disease) and beta-carotene to Vitamin C.

It should be a regular part of your diet. But if you're big into food classification, you might be wondering—is a tomato a fruit? Is it a vegetable? Or is it some weird hybrid of the two?

The answer is that it depends on who's asking. In the world of botany, a fruit is defined as the part that develops from the fertilized ovary of a flower. Vegetables are the edible parts of plants that aren't fruits. By this definition, the tomato is a fruit.

Botanists, however, don't have the last word on the subject. In 1893, the U.S. Supreme Court was asked to decide whether a tomato was a fruit or a vegetable after importer John Nix was slapped with a 10 percent import tax on vegetables coming in to New York's Port Authority. He argued the botanical definition, but the judges disagreed, ruling that in the "common language of the people, whether sellers or consumers of provisions," the tomato was a vegetable.

Nutritionists in particular like to categorize the tomato as a vegetable because it lacks the abundance of fructose (sugar) found in many fruits like oranges and apples. In less formal terms, fruits are also classified based on their ability to be incorporated into desserts due to their sweetness. There's a reason we have apple pie and not broccoli pie.

So is the tomato a fruit? As a seeded growth, yes. Nutritionally, no. If you want to stick to the legal term, according to Nix's case, the tomato is a vegetable. He couldn't prove otherwise. Then again, it might depend on where you live. Tennessee made it the official state fruit, while New Jersey calls it the official state vegetable. Arkansas played both sides of the fence by declaring the tomato both the state fruit and the state vegetable.

Big Questions
What Are Curlers Yelling About?

Curling is a sport that prides itself on civility—in fact, one of its key tenets is known as the “Spirit of Curling,” a term that illustrates the respect that the athletes have for both their own teammates and their opponents. But if you’re one of the millions of people who get absorbed by the sport once every four years, you probably noticed one quirk that is decidedly uncivilized: the yelling.

Watch any curling match and you’ll hear skips—or captains—on both sides barking and shouting as the 42-pound stone rumbles down the ice. This isn’t trash talk; it’s strategy. And, of course, curlers have their own jargon, so while their screams won’t make a whole lot of sense to the uninitiated, they could decide whether or not a team will have a spot on the podium once these Olympics are over.

For instance, when you hear a skip shouting “Whoa!” it means he or she needs their teammates to stop sweeping. Shouting “Hard!” means the others need to start sweeping faster. If that’s still not getting the job done, yelling “Hurry hard!” will likely drive the point home: pick up the intensity and sweep with downward pressure. A "Clean!" yell means put a brush on the ice but apply no pressure. This will clear the ice so the stone can glide more easily.

There's no regulation for the shouts, though—curler Erika Brown says she shouts “Right off!” and “Whoa!” to get her teammates to stop sweeping. And when it's time for the team to start sweeping, you might hear "Yes!" or "Sweep!" or "Get on it!" The actual terminology isn't as important as how the phrase is shouted. Curling is a sport predicated on feel, and it’s often the volume and urgency in the skip’s voice (and what shade of red they’re turning) that’s the most important aspect of the shouting.

If you need any more reason to make curling your favorite winter sport, once all that yelling is over and a winner is declared, it's not uncommon for both teams to go out for a round of drinks afterwards (with the winners picking up the tab, obviously). Find out how you can pick up a brush and learn the ins and outs of curling with our beginner's guide.

Why You Should Never Take Your Shoes Off On an Airplane

What should be worn during takeoff?

Tony Luna:

If you are a frequent flyer, you may often notice that some passengers like to kick off their shoes the moment they've settled down into their seats.

As an ex-flight attendant, I'm here to tell you that it is a dangerous thing to do. Why?

Besides stinking up the whole cabin, footwear is essential during an airplane emergency, even though it is not part of the flight safety information.

During an emergency, all sorts of debris and unpleasant ground surfaces will block your way toward the exit, as well as outside the aircraft. If your feet aren't properly covered, you'll have a hard time making your way to safety.

Imagine destroying your bare feet as you run down the aisle covered with broken glass, fires, and metal shards. Kind of like John McClane in Die Hard, but worse. Ouch!

A mere couple of seconds delay during an emergency evacuation can be a matter of life and death, especially in an enclosed environment. Not to mention the entire aircraft will likely be engulfed in panic and chaos.

So, the next time you go on a plane trip, please keep your shoes on during takeoff, even if it is uncomfortable.

You can slip on a pair of bathroom slippers if you really need to let your toes breathe. They're pretty useless in a real emergency evacuation, but at least they're better than going barefoot.
