蘋果籽的毒性:它們真的有毒嗎?

Apple seeds contain cyanogenic glycosides, compounds that break down in the body to produce cyanide, which has raised concerns about the toxicity of apple seeds. This article will take a closer look at the toxicity of apple seeds and their impact on health.

1. Cyanogenic glycosides in apple seeds

Cyanogenic glycosides are compounds that naturally occur in certain plants. Apple seeds contain small amounts of cyanogenic glycosides. When these cyanogenic glycosides enter the human body, they are decomposed by enzymes to produce cyanide. Cyanide is a highly toxic substance that can harm the human body by preventing cells from using oxygen.

2. Dangers of cyanide

The harm of cyanide to the human body is mainly reflected in its toxicity to the respiratory system and central nervous system. Acute cyanide poisoning can cause difficulty breathing, headache, irregular heartbeat, and can be fatal in severe cases. Long-term low-dose exposure to cyanide may cause chronic poisoning and affect the nervous system and thyroid function.

3. Cyanide content in apple seeds

The content of cyanogenic glycosides in apple seeds is relatively low. Normally, swallowing a few apple seeds occasionally will not cause significant health effects. However, if apple seeds are chewed and swallowed in large quantities, enough cyanide may be released to pose a health risk. It is estimated that it would take approximately 200 apple seeds to release a lethal dose of cyanide.

4. How to avoid cyanide poisoning

To avoid cyanide poisoning, it is recommended to avoid chewing or swallowing apple seeds when eating apples. Special caution is needed with small children because they are lighter and less tolerant to cyanide. Additionally, if you are interested in making applesauce or juice, the apple seeds should be removed during the making process to ensure food safety.

5. Summary

Apple seeds contain cyanogenic glycosides, compounds that break down in the body to produce cyanide, which is potentially harmful to health. While swallowing a few apple seeds occasionally will not cause significant health effects, chewing and swallowing large amounts of apple seeds may release enough cyanide to pose a health risk. To avoid cyanide poisoning, it is recommended to avoid chewing or swallowing apple seeds when eating apples, and to pay attention to the dietary supervision of children.
