What Happens if You Eat Apple Seeds

Apples are a nutritious, fiber-rich snack packed with antioxidants and vitamins but what about the seeds? While most people know not to eat the core, it’s not uncommon to accidentally swallow a seed or two. In most cases, this is harmless. However, eating large quantities of apple seeds or consuming them regularly can come with some unexpected risks.

Here are five serious side effects of eating apple seeds and why moderation and awareness is key.

1. Choking and Airway Obstruction

Apple seeds are small, hard, and slippery making them a choking hazard, especially for children.

Why it’s dangerous:

• Seeds can get lodged in the throat or windpipe, potentially blocking airflow.

• If inhaled, they may reach the lungs and trigger inflammation or infection.

Warning signs include:

• Coughing or gagging

• Wheezing or shortness of breath

• Inability to speak or breathe

Extra caution is needed for young children, who may not chew thoroughly or recognize the danger of small objects. To avoid the risk, remove the core when slicing apples, especially for kids or older adults with swallowing difficulties.2. Upset Stomach

Most people can pass apple seeds without issue. However, for individuals with sensitive digestion or conditions like IBS (Irritable Bowel Syndrome) or IBD (Inflammatory Bowel Disease), even small indigestible particles can lead to:

• Cramping

• Bloating

• Nausea

• Temporary inflammation

If symptoms occur after eating apple seeds especially in those with preexisting digestive disorders consult a gastroenterologist for guidance.

3. Diverticulitis Flare-Ups

People with diverticulitis, a condition where small pouches form in the colon lining, were once told to avoid small, hard foods like seeds.

While current research suggests that small seeds may not cause flare-ups for everyone, some healthcare providers still recommend caution. Apple seeds may:

• Become trapped in diverticula

• Trigger localized irritation

• Contribute to flare symptoms in sensitive individuals

If you live with diverticulitis, ask your provider for personalized dietary guidance before consuming any type of seeds.

4. Allergic Reaction

Though rare, apple seed allergies can occur even in individuals who tolerate the rest of the fruit.

Symptoms may include:

• Rash or hives, especially around the mouth or lips

• Swollen tongue or throat

• Burning sensation in the mouth

• Difficulty breathing

• Dizziness or fainting

In severe cases, this can lead to anaphylaxis, a life-threatening reaction that requires immediate medical attention.

If you suspect an allergy to apple seeds or any part of the fruit consult an allergist for testing and an emergency care plan.

5. Cyanide Poisoning

Perhaps the most talked-about risk of apple seeds is their cyanide content and yes, it’s real.

Apple seeds contain amygdalin, a compound that converts into cyanide when digested. However, the risk is dose-dependent:

• A few seeds = unlikely to be harmful

• A large quantity = potential for toxicity

• Children and those with certain vitamin imbalances may be more susceptible

Symptoms of cyanide poisoning include:

• Rapid breathing

• Severe headache

• Confusion or dizziness

• Seizures

• Loss of consciousness

In extreme cases, cyanide poisoning can be fatal. If a significant number of seeds are consumed particularly in powdered or blended form seek emergency care immediately.

How Many Apple Seeds Is Too Many?

Exact toxicity varies, but estimates suggest that it would take hundreds of seeds consumed all at once to reach harmful cyanide levels in a healthy adult. That said, there’s no reason to take the risk, especially since apple seeds offer no nutritional benefit.

The Bottom Line

Swallowing an occasional apple seed is unlikely to harm you but intentionally eating large quantities can pose serious health risks, from choking and digestive issues to cyanide exposure. Children, people with allergies or chronic conditions, and anyone with a compromised immune system should avoid apple seeds altogether.

To stay safe:

• Always remove the core when preparing apples for children

• Don’t consume apple seeds on purpose

• Seek medical care if symptoms develop after accidental ingestion
