You either love them or you think they taste like a mouthful of literal dirt. There is no middle ground with beets. Honestly, that "earthy" flavor people complain about? It’s actually a compound called geosmin. It’s the same stuff you smell in the air right after a rainstorm.
But if you’ve ever looked at a bunch of deep purple globes at the farmer's market and wondered where did beets come from, the answer isn't a farm in Pennsylvania or a garden in England. It's the salty, jagged coastlines of the Mediterranean.
Long before they were a staple of Russian borscht or fancy goat cheese salads, beets were essentially weeds. Wild sea beets (Beta vulgaris subsp. maritima) still grow today along the coasts of Europe, North Africa, and the Middle East. They don't look like much. They have tough, leathery leaves and thin, wiry roots that nobody in their right mind would try to roast for dinner.
The Original Superfood Was All About the Greens
Ancient civilizations didn't give a damn about the root. To the Greeks and Romans, the "beet" was a leafy green vegetable, much like modern Swiss chard. In fact, chard and beets are basically the same species, just bred for different priorities.
The Greeks loved them. They even offered beetroots (the skinny, non-bulbous kind) to the god Apollo at the temple of Delphi. But they weren't eating the bottom half. They were sautéing the leaves with garlic and wine. It makes sense when you think about it—the leaves are packed with vitamins, and back then, a big sugary taproot hadn't even been "invented" by selective breeding yet.
By the time the Roman Empire was in full swing, people started noticing that the roots were getting thicker. Roman gourmands like Apicius actually wrote down recipes for beets, but they were mostly focused on dressing them with broth and vinegar to mask the bitterness. It wasn't until the 1500s that we started seeing the bulbous, round red roots we recognize today in German and Italian botanical records.
How Beets Conquered the Cold
So, how did a Mediterranean coastal weed become the backbone of Eastern European survival? It’s all about durability.

As the vegetable moved north through trade routes, farmers realized something crucial. Beets are tough. They can handle a frost that would kill a tomato in an hour. Because they grow underground, they are protected from the biting winds of a Polish or Russian winter.
This is where the history of beets gets heavy. For centuries, the beet was "peasant food." While the aristocracy was dining on imported spices and fine meats, the rural populations of the Slavic regions were surviving on the "blood of the earth." Borscht wasn't a trendy soup; it was a caloric necessity. It was cheap, it lasted all winter in a cellar, and it provided enough nutrients to keep you from getting scurvy when fresh fruit was a distant memory.
The Napoleanic Twist and the Rise of Sugar
Here is a weird fact: Beets actually changed the course of global geopolitics.
In the early 1800s, the British Navy blockaded France, cutting off Napoleon’s access to sugarcane from the West Indies. Napoleon was furious. He needed sugar for his troops and his ego. He turned to scientists and offered a massive prize to anyone who could find a local source of sweetness.
Enter the Sugar Beet.
A Prussian chemist named Andreas Marggraf had already discovered that some beets contained the same sucrose as sugarcane, but it was his student, Franz Achard, who actually built the first sugar beet factory. Napoleon loved it. He ordered thousands of acres to be planted with sugar beets. Today, about 20% of the world’s sugar still comes from these pale, ugly, non-purple cousins of your dinner beet.

Why Are They So Red?
The color is intense. If you’ve ever peeled a beet without gloves, you know your hands will look like a crime scene for at least three days.
That pigment comes from betalains. Most plants get their red or purple colors from anthocyanins (like blueberries), but beets are rebels. Betalains are much rarer in the plant kingdom. They are also incredibly stable, which is why beet juice is used as a "natural" dye in everything from strawberry ice cream to red velvet cake mix.
Interestingly, the color wasn't always a selling point. In medieval times, the "blood-red" juice led some people to believe beets could cure blood diseases. This was part of the "Doctrine of Signatures"—the old-school medical theory that plants which look like body parts can heal those body parts. While the theory was mostly bunk, they weren't entirely wrong; beets are high in nitrates, which actually do help with blood flow and blood pressure.
The Modern Identity Crisis
Today, we see beets everywhere. You've got golden beets, Chioggia beets (the ones that look like a candy cane inside), and the standard Detroit Dark Red.
But there’s a massive gap in how we perceive them. In the fitness world, athletes chug beet juice to increase their stamina. Research from the University of Exeter has shown that the nitrates in beets can help muscles work more efficiently by reducing the oxygen cost of exercise.
On the other hand, in the culinary world, they’ve moved from "peasant mush" to "artisanal darling."

Wait, what about the dirt taste? Let’s go back to that "earthy" thing. If you hate beets, you probably had them boiled into a flavorless sludge as a kid. Roasting is the secret. When you roast a beet at high heat, the natural sugars (remember Napoleon?) caramelize. It balances the geosmin. It turns that "dirt" flavor into something rich and complex.
Common Misconceptions About Beet Origins
People often think beets are related to potatoes or turnips. Nope. They are part of the Amaranthaceae family. That means their closest relatives are actually spinach and quinoa.
Another big myth? That the Romans used them as an aphrodisiac just because they were red. Actually, they used them because they contain high levels of boron, which is directly related to the production of human sex hormones. They didn't have microscopes, but they definitely noticed the effects.
Practical Ways to Use the History of Beets in Your Kitchen
If you want to actually enjoy this vegetable instead of just respecting its history, you have to treat it right.
- Don't throw away the tops. Seriously. If you buy beets with the leaves attached, you're getting a 2-for-1 deal. Sauté them exactly like you would spinach. They are arguably the best-tasting part of the plant.
- The "Salt Crust" Trick. Since beets came from the seaside, they have a natural affinity for salt. Burying whole beets in a mound of kosher salt and roasting them creates a mini-oven that concentrates the flavor and prevents them from getting soggy.
- Acid is mandatory. Beets are incredibly sweet and earthy. They need a "bright" partner. Whether it’s a splash of balsamic, a squeeze of lemon, or a dollop of pickled goat cheese, the acid cuts through the heaviness.
- Raw is an option. Most people don't realize you can grate a raw beet into a salad. It adds a crunch that’s totally different from the soft, buttery texture of a cooked one.
The story of where beets came from is really a story of human persistence. We took a salty, scraggly weed from the beach and forced it to become a sugar powerhouse, a winter lifesaver, and a performance enhancer for Olympic runners. Whether you like the taste or not, you have to respect the hustle of the humble beet. It survived the Roman Empire and the Napoleonic Wars just to end up on your plate.
How to Buy the Best Beets Today
- Check the skin: It should be smooth and firm, not shriveled like a raisin.
- Look at the greens: If the leaves are wilted and slimy, the beet has been sitting in storage for weeks. Look for perky, bright green tops.
- Size matters: Smaller beets (about the size of a golf ball) are usually sweeter and less "woody" than the giant ones that look like bowling balls.
- Storage: Always cut the leaves off as soon as you get home. If you leave them on, they will suck the moisture out of the root, leaving you with a soft, bendy beet.
Stop boiling them until they turn gray. Start roasting, start pickling, and maybe give that ancient sea-weed-turned-super-root a second chance.
