There is a popular test called ORAC (Oxygen Radical Absorbance Capacity) which is supposed to quantify the antioxidant quality of various foods. People who sell Acai claim it has the highest ORAC value of any fruit at around 6000 or so for 4 ounces. Different people tend to claim different numbers for many fruits depending on what they are selling, and I haven’t ever seen a good non-biased comparison of everything.
Other fruits and vegetables that have high ORAC values include pomegranate, blueberries, strawberries, prunes, raisins, blackberries, raspberries and dark leafy vegetables like kale and spinach (all over 1000 and in no particular order).
Acai may be as great as they say but I suppose the best thing is to eat your 10 servings a day of various fruits and vegetables, whatever is in season and you can afford. After all, variety is

I have always wondered, isnt ORAC measured in vitro not in vivo? It makes sense that the Anti-O’s found in certain foods would be absorbed in different amounts. Meaning that a food may have a lower ORAC score but actually have more bioavaialable Anti-O’s
