Whole Oranges vs. Orange Juice

Have you ever wondered if drinking orange juice is as healthy as eating the whole orange? Perhaps you haven’t, but many people seem to think that drinking a serving of fruit juice is equivalent to eating a serving of whole fruit. This misunderstanding is reinforced by claims the USDA allows fruit juice companies to make on their products, such as “One serving is equal to one serving of fruit.” I’m not quite sure how the USDA arrived at supporting such a statement (probably because of the lobbying pressure from large food companies), but to say what is in some cases little more than liquid sugar is equal to a serving of whole fruit is preposterous. Don’t get me wrong, some juices are better than others, such as the less refined ones that are unfiltered or with pulp, and fruit juice is usually healthier than soda, but even juice with a little bit of fiber left in it doesn’t compare nutritionally to a serving of whole fruit.

Whole oranges and orange juice provide the perfect opportunity to compare the differences between the two. Check out the picture above of the three glasses of processed oranges. The glass on the left contains the juices of three hand squeezed oranges while the two glasses on the right contain the pulp and juice of three whole oranges that I liquified in a blender (minus the peel). Three whole oranges produced almost twice the volume of material as the juice alone. That extra material is the pulp and pith which contain a number of important nutrients that work together to make the whole orange a highly nutritious food.

To start, the high fiber content of a whole orange helps the body properly process the high fructose content of the juice. The fiber actually blocks some of the sugar from being absorbed, which makes the orange more nutritious for the amount of calories it contains. The fiber also makes a whole orange much more filling than the juice (it’s far easier to consume several glasses of high sugar orange juice than several whole oranges). If you eat a whole orange you’ll also be more satisfied and less hungry for calorie-dense, nutritionally-deficient food later on.

In addition to the benefits of the extra fiber in the pulp, a whole orange contains numerous health promoting micro-nutrients that aren’t found in the juice alone. One of the most researched is a flavanoid called hesperidin, which is concentrated in the pulp and inside of the peel. Hesperidin shows promise as an anti-inflammatory, in lowering blood pressure, and in promoting healthy cholesterol. One animal study also found that a diet rich in orange pulp increased bone density!

I’m not saying that we should never drink orange juice again; studies have shown that fresh-squeezed orange juice has significant anti-oxidant properties. It’s just important to know that the juice isn’t as healthy or satisfying as the whole fruit. Juices and other drinks can be a hidden source of surplus calories for those trying to live healthfully. A diet that emphasizes whole fruits over juices contains fewer sugary calories and more health promoting nutrients!
