You probably didn't wake up today thinking about your geological diet. Most people don't. We talk about carbs, proteins, and keto-friendly snacks, but we completely ignore the mineral staring us in the face. It's on your dinner table. It’s in your boiling pasta water. It is literally the only rock that humans regularly eat nyt puzzles often reference, and its name is halite. Or, as you know it, salt.
Sodium chloride. It’s a literal mineral.
While everything else you consume comes from something that was once alive—plants, animals, fungi—salt is a stone. It is inorganic. If you found a big enough chunk of it in the wild, you’d call it a crystal. Because it is. We are the only species that goes out of its way to mine a specific geological formation just to sprinkle it on a medium-rare ribeye. It’s kind of wild when you think about it.
The Chemistry of Eating Stones
Why do we do this? It’s not just about flavor, though that’s the main reason we reach for the shaker. Your body is basically a salty ocean contained within skin. Every time your heart beats or your brain fires a neuron, you’re using those mineral ions.
Salt is essential. Without it, your nervous system just... stops.
Historically, this made salt more valuable than gold in certain parts of the world. The word "salary" comes from the Latin salarium, which was money given to Roman soldiers to buy salt. They were literally paid in "rock money." When people talk about the only rock that humans regularly eat nyt fans might recall, they're tapping into a history of trade wars, revolutions, and biological necessity.
Mining vs. Evaporation: Where Your Rock Comes From
Not all salt is created equal, at least not in terms of how we get it out of the ground. You have two main camps here.
First, there’s sea salt. This is the "artisanal" stuff. You take seawater, put it in a big shallow pond, and let the sun do the heavy lifting. The water leaves, the crystals stay. It’s a slow, rhythmic process that’s been happening for thousands of years in places like Guerande, France.

Then you have rock salt. This is the hardcore geological version.
Imagine a massive underground cathedral made entirely of translucent white stone. That’s a salt mine. These are often the remnants of ancient, dried-up "ghost seas" from millions of years ago. When you eat Himalayan pink salt, you’re eating a rock that formed during the Jurassic period. You are literally seasoning your avocado toast with a piece of the earth that hasn't seen the light of day since dinosaurs were walking around. That’s not a metaphor; it’s a geological fact.
The "pink" color? That's just rust. Well, iron oxide.
It’s funny how we pay extra for "impurities" in our rocks. Pure sodium chloride is white or clear. But add a little iron, magnesium, or potassium, and suddenly it’s a "premium" health product. Honestly, the nutritional difference is negligible, but the crunch of a large mineral crystal is hard to beat.
The NYT Connection and Why It Trends
Why does this specific phrase—the only rock that humans regularly eat nyt—keep popping up? It’s a classic trivia nugget. It challenges our definition of "food."
Mark Kurlansky wrote an entire biography of salt because it’s the only mineral that has shaped human civilization. Think about it. Before refrigeration, if you couldn't find this rock, you starved in the winter. You couldn't preserve meat. You couldn't travel long distances by sea. Salt was the original technology.
Today, we have the opposite problem.

We eat too much of the rock. The CDC and various health organizations like the American Heart Association have been shouting about sodium intake for decades. But even as we try to cut back, we can't quit it. Our brains are hardwired to seek out this specific mineral because, for most of human history, finding a concentrated source of salt was like winning the lottery.
The Sensory Experience of Mineral Consumption
There is a massive difference between the fine-grain "iodized" salt you find in a blue cardboard cylinder and something like Maldon sea salt.
If you look at Maldon under a microscope, it looks like tiny hollow pyramids. It’s a structural marvel. When those pyramids hit your tongue, they don't just "taste" salty. They provide a structural contrast. This is why chefs obsess over "finishing salts." They aren't just seasoning the food; they are adding a geological texture.
It's weird. We don't eat granite. We don't shave marble over our salad. We don't snack on quartz.
But halite? We can't live without it.
Common Misconceptions About Our Favorite Rock
People often get confused about "natural" vs. "processed" salt. Here's the reality: it's all natural. It's a mineral. Even the most highly processed table salt started as a rock or a brine.
The main difference is the "clumping agents."

To keep table salt flowing smoothly in humid weather, manufacturers add things like calcium silicate. It's also usually "iodized." This started in the 1920s to prevent goiters (swelling of the thyroid). It was one of the most successful public health interventions in history. So, if you only eat "fancy" pink rock salt, you might actually be missing out on the iodine that your thyroid needs to keep your metabolism from tanking.
How to Level Up Your Mineral Game
If you want to actually appreciate the only rock that humans regularly eat nyt editors love to mention, you have to stop treating it as a single ingredient.
- Use Diamond Crystal Kosher Salt for cooking. Most professional chefs use this because the flakes are light and easy to pinch. It’s harder to over-salt your food with this than with fine table salt.
- Save the "Crunchy" Rocks for the end. Use your Himalayan pink or Fleur de Sel right before you eat. If you put it in the boiling water, the beautiful crystal structure just dissolves, and you’ve basically wasted your money on expensive "ghost sea" rocks.
- Understand the "Salt Fat Acid Heat" balance. Samin Nosrat’s famous framework puts salt first for a reason. It doesn't just make things salty; it "unlocks" other flavors. It suppresses bitterness and enhances sweetness.
The Future of the Stone
We are starting to see more interest in where our salt comes from. Much like wine has "terroir," salt has it too. Salt from the Oregon coast tastes different from salt harvested in the Himalayas or the Dead Sea. The trace minerals—the "dirt" of the local area—give each rock a unique fingerprint.
Next time you’re at the grocery store, look at the salt aisle. You aren't just looking at seasonings. You’re looking at a collection of geological samples from around the planet.
It is the only part of the earth’s crust that we voluntarily put into our mouths every single day.
Actionable Insights for the Savvy Eater
To get the most out of your geological diet, start by diversifying your pantry. Don't just own one salt. Keep a coarse rock salt for a grinder, a flaky salt for finishing, and a standard kosher salt for everyday seasoning. This allows you to control the "sodium hit" and the texture of your meals. More importantly, check your labels. If you find yourself feeling sluggish or having "brain fog," ensure you aren't completely avoiding iodized salt in favor of the trendy pink rocks, as iodine deficiency is a real risk in the modern "clean eating" era. Finally, experiment with "dry brining" meat. Applying the rock to your steak hours before cooking allows the mineral to penetrate deep into the muscle fibers, changing the protein structure and resulting in a much juicier finished product.
