Are Humans Omnivores? Why Our Teeth Prove We Eat Everything

Alright, gather ’round folks. Today’s random deep dive started in the frozen food aisle, no joke. Me and my husband were picking out some steak when I suddenly thought, “Wait, are we supposed to be eating both this steak and, like, that broccoli over there? Aren’t we built weird or something?” So, I figured I’d actually look at my own teeth later and see what’s up. Seems like a silly thing to do, but hey, why not.

The Mirror Test (Embarrassing, I Know)

Got home, put the groceries away, and actually stood in the bathroom mirror staring into my own mouth like a weirdo for like five solid minutes. My husband peeked in and thought I’d lost it. Seriously though, I started feeling around with my tongue. Front teeth? Super flat, like little chisels. Perfect for biting into that crisp apple I just bought. Then further back… those pointy ones! My canines, right? Not crazy long like some animal pictures I vaguely remember, but definitely pointy, kind of like tiny little spears. Then, way in the back? Oh yeah, those big, flat molars. Felt like big grinding stones. Huh. Kinda mixed tools right there in one mouth.

Okay, mirror test done. But I thought, “How does this compare to actual meat-eaters or plant-eaters?” Grabbed my phone and went deep on animal skull pictures. Like, deep.

Are Humans Omnivores? Why Our Teeth Prove We Eat Everything

  • Lions/Cats: Whoa. Teeth like knives! Giant pointy canines right out front, sharp back teeth kinda like jagged scissors. Basically all built for slicing meat. No flat ones for crushing.
  • Cows/Deer: Total opposite! Missing a bunch of front teeth? Mostly just a flat pad on the bottom grinding against a hard pad on top? And all their cheek teeth are crazy flat with ridges – pure grinding machines for grass. Zero stabbing points.
  • Us Humans: We got the weirdo combo platter. Not extreme like the lions, not extreme like the cows. We’ve got a little bit of pointy (canines, premolars kinda sharpish), a little bit of chisely (incisors), and a lot of flat grinding action (molars). Seems like we’re kinda built… for a mix. Looking at my own teeth in the mirror again, that mix made total sense. It’s like our mouth is a mini toolbox with different gear.

What Does It Prove? Honestly, Not Rocket Science

Looking at all this – feeling my own teeth, seeing the super-specialized herbivore and carnivore skulls, and then seeing our own mish-mash design – it kinda clicked. Our teeth aren’t super weapons for just meat like a lion. Couldn’t rip hide or bone easily like those big cats. But they also aren’t only grinding mills for tough plants like a cow. We’d struggle hardcore on a diet of just grass.

So, based on what’s literally right there in my mouth and confirmed by staring at pictures online for an embarrassing amount of time, yeah, it sure looks like we’re built to handle a bit of everything. Fruits, veggies, nuts, meat – our mixed bag of teeth types seems geared up for that variety. Felt like a lightbulb moment, even though it seems obvious when you look. Makes sense why I feel fine after a salad or a burger (or, let’s be real, both on the same plate!).

Anyway, that was my weird afternoon project. Felt my teeth, looked at scary skull pics online, learned a little something about my own chompers. Pretty cool, right? Now, excuse me while I go eat a sandwich with turkey and lettuce. Tooth-approved!
