Walnut Kernel Blackening and Its Benefits

Walnut kernel is a common type of dried fruit in our daily life. It is rich in nutrients and has many benefits for the human body. Walnut kernel has always been known as the "brain-boosting fruit". However, if walnut kernel is stored in a damp or moldy environment, it may turn black, and such walnut kernel cannot be consumed as it may have a negative impact on health.

Causes of Blackening of Walnut Kernel

When the walnut kernel turns black, it is usually due to mold or dampness, causing it to spoil. The blackened part is the spoiled walnut meat, which tastes bitter and should not be consumed. Consuming any moldy or spoiled food can lead to food poisoning, gastroenteritis, and other health issues. Eating excessive amounts may also cause bloating and potentially lead to cancer.
