How Many Apple Seeds Will Kill a Human
How Many Apple Seeds Will Kill a Human? The Whole Scary, Silly, and Surprisingly Simple Truth
Raise your hand if you’ve ever eaten an apple, crunched through a seed, and immediately heard your brain whisper, “Wait, aren’t those poisonous?” Maybe you were seven, or maybe you were in your twenties and just embarrassed to ask out loud. Don’t worry—you’re not alone. I’ve done it, my cousin has done it, even my grandma who claims she “knows everything” has done it. Apple seed anxiety is universal.
Let’s settle the question once and for all—just how many apple seeds would actually be dangerous? Is there any truth to the scary stories? Or is this just another one of those things parents tell us to make us spit out the bits that get stuck in our teeth?
The Classic Kitchen Warning
I remember being a kid, sitting at the kitchen table, and hearing my mom say, “Don’t eat the seeds, beta! They’re poisonous.” She’d pluck them out, pile them on the plate, and move on like it was totally normal. No explanation, just a rule. Sometimes it was my dad, who’d go further: “They can KILL you.” (Thanks, Dad. Enjoy your apples, kids!)
My brother, on the other hand, didn’t care. He’d eat the apple, seeds and all, and just shrug. “Tastes the same to me,” he’d say, mouth full. For years, I thought he was living dangerously—then I realized he was just too lazy to pick the seeds out.

So, What’s Actually Inside an Apple Seed?
Here’s the science, no jargon:
Apple seeds contain a compound called amygdalin. When you chew the seeds, amygdalin can turn into cyanide in your body. Yes, cyanide—the same scary stuff you read about in detective novels and spy movies.
But—and this is a big but—the amount is tiny. If you swallow the seeds whole, nothing really happens. The shell is so hard, it passes through your digestive system untouched, like a tiny, harmless pebble. You literally just poop it out. Sorry for the mental image.
It’s only if you chew a lot of seeds that your body starts converting amygdalin into cyanide, and even then, your body can handle a small amount before it ever gets dangerous.
How Much Is Too Much? (Let’s Do the Math, The Fun Way)
Let’s get a little nerdy for a second.
Most apples have between 5 to 8 seeds inside. But one seed is really, really low in amygdalin. The actual amount of cyanide produced per chewed seed? Less than a milligram.
For an adult, the “estimated lethal dose” of cyanide is about 50–300 mg. That’s a huge range, but even on the low end, you’d have to eat and chew somewhere between 150 and 300 apple seeds in a short period for it to be even close to deadly. (That’s the seeds from around 20 to 40 apples, chewed thoroughly and all at once. Who does that? Nobody.)
The math gets even funnier when you think about apples per pie—imagine trying to eat 30 apples at once, seeds and all. You’d probably explode from fruit overload before the seeds ever hurt you.

Real Stories: Did Anyone Ever Actually Get Sick?
This is the part where most people expect a spooky story about someone keeling over from eating apple seeds. The truth? There are a couple of rare cases, usually involving little kids who ate a lot of chewed seeds, or adults who tried to make “natural” extracts by grinding pounds of seeds for home remedies. Spoiler: bad idea.
But in all the thousands of times someone has accidentally swallowed a seed or two, nothing dramatic has happened. I’ve never met anyone who got more than a mild stomachache (and honestly, it was probably from eating too many apples, not the seeds).
Why Do Apple Seeds Even Have Poison in Them?
Good question. It’s not like apples are out to get us. Scientists say it’s the plant’s natural defense—a way to stop insects and animals from destroying the seeds so easily. Most fruit seeds have tiny doses of chemicals to protect themselves. Humans just happened to invent the internet and freak out about it.
What Happens If You Swallow Apple Seeds Whole?
Basically, nothing. Whole seeds don’t get digested. They just slide through your digestive tract. If you didn’t chew them, your stomach acid isn’t strong enough to break down that hard shell.
I’ve probably swallowed a hundred seeds in my life (most of them by accident, I swear), and I’m still here typing this. My friend once ate a whole apple, core and all, on a dare. He was fine, except for the time he made the mistake of telling his mom—then she freaked out for him.
Why Do People Keep Saying Apple Seeds Are Deadly?
Maybe it’s one of those stories that just sticks because it sounds dramatic. “Cyanide” has a big scary ring to it. And yes, in large doses, it absolutely is dangerous. But so is water if you drink 10 liters at once. (True story, look it up!) The point is, dose makes the poison.
My grandma once told me that her neighbor’s aunt’s cousin got sick from eating apple seeds. Then she admitted she’d never actually seen it happen—just heard the story. That’s how food myths are born.
What About Kids and Pets?
Alright, here’s the one time to pay a little attention:
Small children and tiny pets have much smaller bodies, so they’re more sensitive to things like cyanide. But still, you’d have to hand a kid a huge pile of apple seeds and ask them to chew every last one. Kids spit them out more often than not.
If your dog eats an apple core, don’t panic. A few seeds aren’t likely to harm a medium or big dog. If they eat a lot, call your vet. Same goes for little pets—better safe than sorry.
What If I Accidentally Chew a Few Seeds?
Here’s what actually happens to real people:
-
Maybe a slight bitter taste in your mouth.
-
Maybe you feel a little worried (that’s your brain, not your body).
-
Maybe you Google “will apple seeds kill me” (don’t lie, you’ve done it!).
-
Absolutely nothing else. You go on with your day.
I once bit into a really crunchy apple, ended up chewing half the core, and panicked for an hour. My friend laughed, handed me another apple, and said, “Let’s see what happens.” Spoiler: nothing did.
Are Other Fruit Seeds Dangerous Too?
Yep! But again, not in “normal” amounts.
-
Cherry pits, apricot kernels, peach and plum seeds all have amygdalin too—sometimes even more than apples.
-
Still, you’d have to really go out of your way to crack, chew, and swallow enough to cause trouble.
Most people, most of the time, just spit out the seeds and move on. Or forget about them and live to tell the tale.
FAQ – The Actual Stuff People Ask Me
Did you ever get sick from apple seeds?
Nope. Not me, not anyone I know. If I ever do, I promise to write a dramatic update.
Do you really have to worry about one or two seeds?
Not even a little bit. The only thing you have to worry about is getting one stuck in your teeth.
Can eating lots of apples every day be dangerous?
Unless you’re also eating and chewing hundreds of seeds at once, you’ll just end up really, really full. Or maybe need a bathroom break.
What about apple juice or cider—do they use the seeds?
Most commercial juices filter out the seeds. Even if a couple get blended in, the amount of amygdalin is way too tiny to matter.
Why are people still scared of this?
Because “cyanide” sounds wild, and nobody wants to risk it for a snack. But the real risk is basically zero for anyone eating normal apples.
Is it different for pregnant women, old people, or folks with health issues?
Again, unless you’re eating seeds by the handful, no doctor’s going to worry about the odd apple seed.
What if my pet ate an apple core?
Most of the time, nothing. But if your pet is small, or you’re nervous, call the vet. Dogs and cats are more sensitive, but it takes a bunch of seeds to matter.
Apple Seeds and Urban Legends (Or, Why My Family Still Worries)
I think food fears are half science, half family drama. My aunt tells a new version of the apple seed story every year—sometimes the neighbor got sick, sometimes it’s a mysterious person on WhatsApp. Every single time, the story ends with, “So just spit out the seeds, okay?”
Honestly, I still spit them out most of the time, just to avoid the lecture.
There’s something universal about these food myths. Maybe they’re just a way for parents to feel like they’re protecting us. Maybe it’s just tradition, passed down with every lunchbox apple.
So… How Many Apple Seeds Will Kill You?
Let’s be 100% clear:
You’d have to chew up and eat the seeds from at least 20 to 40 apples at once (over 150–300 seeds) for it to even be potentially dangerous for an average adult.
And that’s chewed seeds, not swallowed whole.
Nobody’s doing that by accident. Not even your weirdest friend.
One or two? Totally harmless. Ten? Still nothing. A whole apple core at once? You’re fine.
The only way apple seeds would “kill” you is if you literally made it your mission to prove this article wrong (please don’t).
My Honest, Messy Conclusion
So yeah, apple seeds have a trace of poison. But the real poison is letting food myths ruin your snack. Life’s too short to stress over the little things—especially when you’re just trying to eat healthy.
If you’re still worried, just spit out the seeds and move on. And next time someone warns you, tell them: “I’d need to eat 30 apples and chew every seed to even worry.”
Then grab another apple, crunch away, and enjoy the juicy part—no stress, no drama.
