I'm going to pass up the opportunity to crack the joke "orange you glad…" and simply go on to say that oranges are an AWESOME fruit! They're one of the best sources of Vitamin C, plus they're a supremely versatile food that can be used to make juice, oil, jam, and so much more! Oranges contain about 65 milligrams of calcium (or 6% of your calcium DV) per medium-sized fruit. Eat a few oranges a day, and you've got a lot more calcium in your diet, not to mention a whole lot of Vitamin C.

Not only does it promote healthy immune function, but it reduces oxidative stress--caused by toxins and chemicals. By eating more oranges, you are going to protect your heart, brain, liver, and all other organs effectively. The orange rind contains a lot of nutrients, which is one reason that marmalade is one of the healthiest jams on the planet.
