The purple skin on the surface of purple-coated cashew nuts is not toxic, and it can be eaten if you want. Moreover, this purple skin is also rich in dietary fiber, which can also promote gastrointestinal peristalsis and supplement trace elements to the human body after eating. However, this layer of purple skin also contains a certain astringency, which is bitter to eat and may affect the taste of cashews themselves. Therefore, from the taste point of view, it is recommended not to eat.
