What You Need to Know About Apple Seeds & Cyanide

Amygdalin, a compound in apple seeds, undergoes metabolism, converting into hydrogen cyanide, a deadly toxin. This revelation highlights the potential danger lurking within certain fruits’ seeds, encompassing cherries, peaches, almonds, and more, due to their cyanogenic glycosides.

The sinister association of cyanide extends beyond apple seeds, linking to other fruits harboring cyanogenic glycosides like cherries, peaches, and almonds. Additionally, plants like tapioca contain cyanide precursors, linamarin, requiring meticulous preparation to render them safe for consumption. Failure to do so can lead to high toxicity levels.

The lethal potency of cyanide, merely 100-200 mg when ingested or 270 parts per million when inhaled, underscores its alarming impact. While swallowing a few apple seeds might not prove lethal, even minuscule amounts of cyanide can remain benign for the human body. However, children and pets are significantly more vulnerable to cyanide’s lethal effects.

Cyanide’s mode of action, disrupting the body’s oxygen utilization, leads to asphyxiation. Binding to enzymes within mitochondria, cyanide inhibits oxygen production, causing rapid fatality. Moderate cyanide poisoning manifests as lightheadedness, vomiting, and nervousness, escalating to severe symptoms like convulsions and unconsciousness at lethal doses.

Historically limited to stomach pumps and induced vomiting, treating cyanide poisoning encountered breakthroughs with the advent of powerful antidotes like Cyanokit post-2006. Swift’s administration of these antidotes becomes pivotal in counteracting cyanide’s lethal effects, offering hope for effective treatment in critical scenarios.

Understanding Cyanide Poisoning

Eating certain plants containing cyanogenic compounds like apricot seeds, almonds, cassavas, and apple seeds can induce cyanide poisoning in humans. Mild symptoms range from anxiety and headaches to dizziness and confusion. However, acute poisoning can cause severe complications like decreased consciousness, high blood pressure, paralysis, and coma. In some unfortunate cases, it can be fatal, especially for young children who are at a higher risk due to their body weight.

Assessing Lethal Doses and Apple Varieties

Determining the lethal potential of apple seeds depends on multiple factors: an individual’s body weight, tolerance levels, and the apple’s variety. The amount of amygdalin, the cyanide precursor, present in apple seeds varies based on the apple type and its growing conditions. Even when amygdalin isn’t lethal, smaller doses can still induce sickness, making it crucial to recognize the potential risk associated with consuming apple seeds.

Apple Juice Risks

Apple juice and smoothies commonly include crushed apples, encompassing seeds and cores. During processing, these seeds might release cyanide, which can persist in the juice. Research investigating amygdalin levels in commercial apple juice found minimal amounts—ranging from 0.01–0.04 mg per milliliter in pressed apple juice to 0.001–0.007 mg per ml in long-life apple juice. While deemed unlikely to cause harm, caution prevails, prompting recommendations to avoid apple seeds and remove them before juicing due to their amygdalin content.

Health Benefits Of Apple Seeds In Moderation

  • Apple seeds contain cyanogenic glycosides, including amygdalin, a compound that can release cyanide when metabolized. In moderation, the cyanide content in apple seeds might offer potential health benefits, although this is a subject of debate due to the inherent risks associated with cyanide.
  • While cyanide is toxic in large doses, proponents suggest that amygdalin, in controlled amounts, might possess antioxidant properties. This compound has been explored for its potential to combat oxidative stress, which can contribute to various health issues, including chronic diseases.
