Fruit is designed to look good. Not just in the way it is presented in stores, though that is a part of it, but the way it naturally grows. While it's easy to simply think of fruit as healthy food to make up part of a balanced diet, it is mostly a means of spreading seeds.
It is a pretty mutually beneficial relationship we have - animals eat the fruit and receive nutrients and good taste, and in turn they disseminate the seeds of the plant into different areas. But to get humans and other animals interested in the first place, they need to look good enough to eat. And for the most part, they do. But it turns out when you entirely remove the skin of certain fruit, their image completely changes, and not for the better.
