Defining “healthy” is so complicated that even the Food and Drug Administration doesn’t do it, leaving the rest of us to come up with our own definitions. Does fruit match yours?

They are whole food that grows naturally, but many of them also have surprisingly high amounts of sugar. And while an apple a day keeps the doctor away, moderation is key when it comes to just about everything — while no one would argue that fruit is unhealthy, most of us would agree that it’s possible to have too much of a good thing. The evidence suggests that’s pretty difficult when it comes to fruit, however, and that it’s very much part of a balanced nutritional intake.
