Goji, noni, mangosteen, acai, they're exotic sounding foods from far off countries, and juice makers are bottling them with a promise that these super juices can protect you from diseases with their ultra-high levels of antioxidants. But can these ultra expensive juices in fancy bottles really improve your health?

Australian consumer organization Choice recently compared some of these exotic juices and the results might surprise you. Though they are high in antioxidants, they often aren't any higher than fruits and vegetables that you can find (and even grow) in your own backyard. And though there are a handful of studies that link these juices to disease prevention, studies involving humans are lacking.

It's your heard earned dollar, so you're welcome to spend it how you wish. But keep in mind that all of the juices tested had a lower total antioxidant capacity (TAC) than a red delicious apple, a fruit that will soon be in season and can be purchased for less than a buck.
