The Poisonous Part of Lychee
While lychee is an incredibly nutritious fruit, it is important to note that there is a potentially dangerous aspect to the fruit as well. The seeds of the lychee fruit contain a toxic substance called hypoglycin A, which has been linked to a serious health condition known as acute encephalopathy in children.
Acute encephalopathy is a life-threatening illness that affects the brain function of young children. The condition is most commonly seen in the lychee-growing regions of India and Bangladesh, where children who consume large quantities of unripe or under-ripe lychees are at risk for developing the condition.
In order to prevent the toxic effects of hypoglycin A, it is recommended that lychees are fully ripe before consuming, and that you avoid consuming large quantities of lychees at one time.
| Food Item | Hypoglycin A Content (mg/g) |
|---|---|
| Unripe lychee fruit | 100-500 |
| Ripe lychee fruit | 0.2-0.6 |
| Lychee seeds | 4.8-19.7 |
As you can see from the table, the hypoglycin A content in lychees varies greatly depending on whether the fruit is ripe or not, as well as on the part of the fruit that is consumed. By being aware of these factors and taking proper precautions, you can still enjoy the many health benefits of lychee without putting yourself at risk for toxicity.
