Know it: Everyone knows that fresh fruits and veggies are healthy. Sadly, manufacturers take advantage of that trust by slapping this label on anything with a fruit product in it. This may include fruit concentrates, which are essentially just sugar and things like beet juice for coloring. Many popular fruit roll ups are mostly high-fructose corn syrup and food coloring. Sure, some "real" fruit might be in there, but it certainly doesn't have the benefits of an actual piece of fruit.
Avoid it: Eat real, whole fruits and vegetables. They should have exactly one ingredient.
