A friend tells you that he could eat nothing but fruit all day long. is this a healthful way of eating?

Although this may sound like a healthy way of eating since his diet contains a healthy snack such as fruits, it is not a healthy diet.

Explanation:

A healthy diet consists of many things. As in reference to the food chain, fruits are required for a healthy diet. Though, that is not all. A healthy diet is a mix of fruits, vegetables, protein such as meats, grains, and more. If someone were to live off of only fruits, that would nourish some parts of the body but without the others, then the whole body simply preforms a bit wobbly.
