What are the benefits of acai berry?

The açai berry is a tropical berry that grows from the Açai palm that also has some antioxidants, but less than that of concord grapes, black cherries, or blueberries. Claims that it can aid in weight loss are unsubstantiated by any scientific study. It should be noted that while fruit and berries are good for you as part of a healthy and balanced diet, there is no single food, berry or otherwise, that can cure all your ills (try good food and exercise, and see a doctor), make you lose weight (try good food in moderation, and plenty of exercise). Many foods provide specific benefits as supplements to your diet, but they will not magically reverse obesity and sloth- these you will need to address before expecting miracles.
