The berry itself contains a compound called Anthocyanins, which belongs to a group of plant compounds called flavonoids. These flavonoids are important because they are artery protectors and help neutralize key enzymes that destroy the connective tissues in the body.
The acai berry has shown to have up to 30 times more flavonoids than red wine, which has been touted as being heart healthy when consumed in moderation.
Acai is also loaded with minerals, vitamins and are high in omega-3 fatty acids, which are all extremely important if you are interested in heart health, cholesterol, maintaining a good blood pressure and increasing bone and joint strength.
But it is the antioxidants that are the claim to fame for this unique berry. It is known to have the highest antioxidant capacity than any other edible fruit (http://articles.mercola.com/sites/articles/archive/2008/12/30/is-the-superfood-acai-worth-the-price.aspx) and is said to have 300 percent more antioxidants than traditional blueberries or grapes.
Antioxidants support a healthy immune system, provide energy and have remarkable anti-aging properties.
We now know that acai berry can have some very positive health benefits for us but just like anything else that is new on the market, it will be credited for doing a lot more than it actually can.
Of course, I am mainly talking about weight loss. At this point in time, there is no published data that states that it effectively aids in weight loss although it does help with faster metabolism and better digestion.
So if your reason for spending the money on acai (this berry is not cheap either) is that you can quickly lose extra weight, you might as well invest it on a healthy lifestyle including eating whole foods, buying exercise equipment so you can be consistent with a daily routine and a daily journal to monitor and track your progress.
Another reason to be careful is the product itself. The juices and powders that you find at your local grocery are more than likely not pure acai berry. By the time we get it from South America, were probably dealing with a whole bunch of added flavorings or sweeteners.
If you are confident that you got the real deal (pure), then this might be a great alternative for someone with high blood sugar who normally can't drink regular juice. Pure acai juice has low natural sugar content, much lower than commercial juices.
