Hi Welshbunny,
Acai Berries are either the latest fad superfood, best weight loss product ever developed or a very nutritious berry, depending on who you speak to. There's a lot of media hype associated with the humble berry from Brazil, but there are some facts which are undisputed. It is has an extremely high concentration of antioxidants. It has an ORAC (Oxygen Radical Absorbance Capacity) value of 5500 for the raw fruit and approximately six times that for the processed product. ORAC is a measure of the antioxidant value and potency of a given food. Foods with a high ORAC value help promote health by increasing plasma antioxidant levels, and as a result reduce cell damage from free radicals. Now that's what is scientifically proven. In terms of the benefits of Acai, there has been good feedback from users for weight loss and also for improving skin tone. It is a pretty amazing fruit but it is no wonder drug. Like most natural products, different users will respond to it in different ways. If you want to get some real hard facts about it, search google scholar for some scientific papers on it, many of them are in fact quite readable. Here's a list of links to some articles by reputable sources.

Hope that helps,

PS I have tried it myself when we first started stocking it at Rainforest Foods, I noticed an immediate increase in energy. I didn't lose any weight on it but that's possibly due to me only taking it for a week.
