39. You guzzle pulpy OJ to up your fiber intake

THE RESULT: Lots of vitamin C but no fiber.

THE FIX: Even though the pulpy stuff seems like it would contain fiber, it doesn’t. Most of the fiber in an orange actually comes from pectin in the white inner portion of the peel that surrounds the segments. This fuzzy layer, called the albedo, is removed in the juicing process, along with the fiber (2.5g per medium orange). With or without the pulp, 4 ounces of fresh orange juice may not offer any fiber, but it does supply 83% of your daily vitamin C—about the same as the whole fruit.
