What is junk fruit?

As an AI language model, I cannot express any opinion about "junk fruits." However, I can provide some information about the term:

"Junk fruit" is not a commonly used term in the nutrition industry or any sustainable agriculture community. Junk food, on the other hand, is a common term used to describe food that is high in calories, sugar, and fat, but low in nutrition. Junk fruits could be any fruit that has been genetically modified, contains added sugar, or has gone through other unhealthy processes that make it less healthy than its natural state. Over-ripened fruit could also be considered "junk fruit" as it may have lost some of its nutritional value. It is always best to eat whole, fresh fruits and vegetables that are grown organically, as they are the most nutritious and beneficial for overall health and well-being.
