Apple seeds contain amygdalin, a natural compound that releases cyanide—a highly toxic chemical—during digestion. Cyanide affects the heart and brain, and a sufficiently high dose can lead to coma and even death.
According to data from the U.S. Centers for Disease Control and Prevention, a lethal oral dose of cyanide is between 1 and 2 milligrams per kilogram of body weight. In other words, to receive a fatal amount of hydrocyanic acid, one would need to swallow—and thoroughly chew—200 seeds. This amounts to the seeds from roughly 40 apples.
However, experts assure that accidentally or intentionally swallowing a few apple seeds poses no danger. The body can easily neutralize small quantities of cyanide. Furthermore, when seeds are swallowed whole, their tough outer shell protects them, preventing any harm.
Apples themselves offer many health benefits. They help maintain gut health thanks to pectin, a soluble fiber that serves as food for beneficial gut bacteria.
They are also good for the heart, as they lower levels of “bad” cholesterol through the action of fiber, polyphenols, and antioxidants. Another beneficial property is that apples help prolong the feeling of fullness while being low in calories, which aids in weight management.
