What's more nutritious, orange juice or an orange? It's complicated

The general advice is to opt for the fruit, since juices are stripped of the fiber – which most us don't get enough of — in whole fruit. And let's face it: Most juice contains a lot of sugar, which most of us consume too much of.

So NPR's interest was piqued when they spotted a study suggesting that, when it comes to oranges, juice might actually unlock more carotenoids and flavonoids – both beneficial phytonutrients — than an equivalent amount of fruit.

There's also a question of calories: An 8-ounce glass of juice has roughly the same amount of energy as two oranges.
