There is no single fruit that is considered "heat" for the body. The concept of "heat" in traditional Chinese medicine refers to foods and substances that are believed to have a warming effect on the body. This is not a scientific concept, but rather a cultural belief system.
While some fruits, like mangoes, papayas, and bananas, are considered "heat" in this context, it's important to remember that this categorization is based on traditional beliefs and not scientific evidence.
The "heat" or "cold" nature of foods is not a universal concept and can vary depending on individual beliefs and cultural backgrounds.
