Açaí Palm (pronounced [asaˈi]) grows in tropical Central and South America. Its fruit is a small, round, black-purple drupe, similar in appearance and size to a grape and supposedly contains 10 times more antioxidants than red grapes and 10-30 times the anthocyanins of red wine.
Dr. Perricone's calls Açaí superfood No. 1 on Oprah Winfrey's website. There are few studies in the peer-reviewed literature which seem to confirm the high antioxidant content of the berries.
The anonymous author of the Happy Hospitalist blog have tried taking Acai-based juice for 4 weeks and seems very happy with the result (or may be he was happy to begin with it?).
A colleague of mine was intrigued and took "Standardized Açaí, 60 Vcaps" by Nature's Way for 2 weeks but he did not report any significant difference. For now, I will stick to my cup of green tea in the morning.
