Are Apple Seeds Safe to Eat?

When it comes to fall, the apple reigns supreme. This season brings a bounty of apple-based recipes, from cinnamon-spiced delights to apple desserts (think apple pies, cakes, and crisps) and savory dishes with a touch of sweetness from this beloved fruit.

However, apples also come with a hidden danger—apple seeds. If you’re not careful, consuming them can lead to serious health issues. Read on to learn why it’s best to avoid apple seeds and how to safely remove them.

Are Apple Seeds Harmful?

Yes, apple seeds can be dangerous, but only in large amounts. While the occasional seed isn’t a concern, eating a significant number of them could lead to cyanide poisoning. “Apple seeds contain amygdalin, which breaks down into cyanide when metabolized,” explains Jacek Szymanowski, certified nutritionist and health coach.

Just to clarify, we’re talking about consuming a large number of apple seeds. “An adult would need to eat around 150 apple seeds to be at risk of cyanide poisoning, while children could be affected by as few as 83-100 seeds,” says Szymanowski. “On average, an apple contains about eight seeds.” Nevertheless, it’s always safest to avoid intentionally eating apple seeds, just to be cautious.

Apple seeds aren't the only ones to watch out for. Other seeds, like those from apricots, peaches, plums, cherries, nectarines, lemons, pears, almonds, and watermelons, also contain amygdalin, which can lead to cyanide poisoning. This is a good reminder to keep these seeds and pits away from your pets, too!

What to Do If You Accidentally Eat Too Many Apple Seeds

If you've consumed a small number of apple seeds, there's no need for concern—just wait for them to pass naturally through your digestive system. “They should exit your system within 24-48 hours, depending on your digestion,” says Szymanowski.

However, if you or someone else consumes a large number of apple seeds, be vigilant for signs of cyanide poisoning: dizziness, nausea, and headache. If any of these symptoms occur, seek medical help immediately, especially since children are more vulnerable to cyanide poisoning.

The Best Way to Remove Apple Seeds

To avoid any worries about apple seeds, the best approach is simply to remove them. Szymanowski suggests using an apple corer or a small knife to easily extract the seeds.

• With a knife: “Slice the apple into halves or quarters to expose the core and seeds,” Szymanowski says. “Use a small knife to remove the core and seeds.”
• With a corer: Carefully insert your corer into the apple, press down, and twist to remove the core and seeds.
