\"Smoothie Recipe\"
Because of the mass appeal for antioxidants, many companies have marketed various ready-to-drink juices as being "the best source" of antioxidants that money can buy. It is therefore of great interest to the general public to know the antioxidant capacity of the beverages that they consume.
Just how antioxidant-rich are these juices? And how do they compare with fresh-pressed juices?
To help answer this question, a recent study published in the Journal of Agriculture and Food Chemistry compared the antioxidant status of 12 brand name ready-to-drink juices.
However, it should be cautioned that because of the inherent complexity of food matrices, the use of a single antioxidant capacity method (used in many other studies) to determine antioxidant potency is ineffective. This is because antioxidants respond to different reactive species in different tests, which is partially attributed to multiple reaction mechanisms and reaction phases.
Instead, for better accuracy, the current study used 4 separate tests to measure antioxidant potency.
The study's main aim was to measure the antioxidant potency of pomegranate juice versus several brands of apple juice, açaí juice, black cherry juice, blueberry juice, cranberry juice, Concord grape juice, orange juice, red wine, and iced tea beverages (black tea, green tea, and white tea flavours).
The results of the study showed that pomegranate juice had the highest antioxidant capacity and the most complete antioxidant coverage. In addition, there was extensive evidence of physiological activity of this juice in humans with regard to intima media thickness, cardiac blood
