The acai (pronounced ah-sigh-ee) berry, once a no-name fruit from the Amazonian palm, has in recent years soared into the world's nomenclature for its health benefits. It's been promoted for its high antioxidant content and its ability to improve digestion, detoxify the body and slow down aging. It's also become popular as a dietary supplement to promote weight loss [source: Zeratsky].
The acai diet became popular after Dr. Nicholas Perricone lauded the berry's high antioxidant benefits on the Oprah Winfrey Show. There isn't an exact regimen for this diet, but the idea is to incorporate these supplements into your daily routine. The cost of using supplements ranges from $40 to 80 each month, and they can be bought in various forms, including as a juice or capsule. Keep in mind that the supplements aren't regulated by the U.S. Food and Drug Administration. And unfortunately, acai's health benefits, particularly those of weight loss, haven't been scientifically proven [source: Center for Science in the Public Interest].
