There is no reason that you would be banned from eating an acai berry, or drinking acai berry juice. If the acai is banned, then so should be blueberries, apples, bananas, and cranberries. I really can't figure out how the acai berry turned into such a bogus fad. It doesn't do anything for you above and beyond what you would get from many other common fruits. People talk about it being high in antioxidants, but that isn't really true. There are plenty of commonly eaten fruits that are higher. A well conducted study in 2007, set out to determine how fruits ranked in terms of their level of antioxidants. The study showed that an apple had a total antioxidant capacity, or TAC, of 5900. The acai berry was only measured to be 1800. Pretty poor for a "super fruit". Not to mention, let me clear up something about all the buzz surrounding antioxidants. People seem to think that if they can just pour a dump truck full of antioxidants down their throat they'll live longer, healthier lives. Not so fast. As you may know, antioxidants bind free radicals in our body. One way our cells can be attacked is when they are bound by free radicals, thus oxidizing it. So to reduce the amount of free radicals is good, right? Well, to a degree. But our human biochemistry is not as simple as the seller's of these fads want you to believe. The oxidation from free radicals also has important benefits in our body, like converting fat into energy, and attacking bacteria. Scientists have studied antioxidants extensively, and here is what they've found. A certain amount is good, but too much is bad. And the source of the antioxidant is certainly relevant (the best sources being vitamin C, vitamin E, and beta-carotene).
The point is, go eat an apple. And quit paying top dollar for every health fad that is featured on Oprah.
