It seems like everyone out there has another antioxidant or miracle juice that will solve all your problems- and all are willing to tell you why theirs is the best. It can be very confusing, trying to research all these different product and establish which ones are good for you, and which ones are overpriced and heavily marketed fruit juices. There are a few key things to look at when you are investigating a product.
Firstly, what is an antioxidant? An antioxidant is a molecule capable of inhibiting the oxidation of other molecules. What is oxidation? Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reactions can produce free radicals- these radicals can start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. Examples of antioxidants include vitamins C, E, and A, and other substances including beta-carotene, lycopene, glutathione, Lutein, Selenium, Resveratrol. Antioxidants have been linked to reduced risks of cancer, cardiovascular disease, gum disease, etc. In summary, antioxidants are good for our health.
How is an antioxidant measured? Dr Cao of the National Institute of Aging developed a test called The ORAC (Oxygen Radical Absorbance Capacity) Assay in 1992 to measure the level of antioxidant protection of a product as well as the duration of the protection.
ORAC measures the degree, which a product inhibits the action of oxidative agents and the length of time this inhibitor occurs. The ORAC Assay integrates the strength and duration of antioxidant protection for a product into a single numerical value (called the ORAC score) and has been shown to highly correlate with the level and the time of protection in cells, body tissues and blood levels. In others words, there is a near perfect correlation between the ORAC value and the antioxidant and immune system protection in the body. This is important because oxidative stress has been demonstrated to accelerate the aging process in both cells and blood vessels. Oxidative stress also increases the risk of certain types of cancer, coronary heart disease and many other health maladies.
You get antioxidants in the food that you eat- primarily your fruits and vegetables, but given the busyness of modern life it is very hard to get enough antioxidants on a daily basis- not to mention degrading food quality. This is one of the reasons antioxidant juices have come about, as a convenient way to get the antioxidants your body needs. Some key things to look at in an antioxidant juice:
1) Superfruit- Every juice WILL have a superfruit in it- and will be heavily marketed on that fact. The 3 main ones are: Acai Berry, Goji Berry (also known as the wolfberry), and the Mangosteen Fruit. Here is a list of some of the antioxidant values of the top scoring fruits.
| Wolfberry, Ningxia, dried | 30,300† | |||
| Wolfberry, Chinese | 20,200† | Importance of “Ningxia” | ||
| Mangosteen | 20,000? | No independent proof | ||
| Acai | 18,400† | |||
| Raspberry, Black | 16,400† | |||
| Pomegranate | 10,500† | |||
| Prune | 5,700† | |||
| Blackberry | 5,100† | |||
| Boysenberry | 3,500† | |||
| Blueberry | 3,200† | |||
| Plum | 2,800† | |||
| Raspberry, Red | 2,700† |

| *ORAC SCORE* |
Although the fruit itself may score high- when it is processed into a product it may lose some of its antioxidant value. Also, the drink should include whole parts of the fruit- a puree – not just extracted fruit juices.
2) Filler Juices – Every juice will have the superfruit- but what else is in the drink? Some warning signs of an inferior product are sugary, high glycemic index low antioxidant value filler ‘junk’ juices like apple, pear, and grape. These contain very little antioxidants themselves, and are cheaper to include in the beverage. Not only do they have a lower antioxidant value- they are high glycemic index- meaning they will have more of an effect on your blood sugar levels- and are probably not diabetic safe either. You should be looking for juices that are lower glycemic index, high antioxidant value that contribute to the synergy of the juice- taken from the list above, some good ones to look for are raspberry (black or red), blueberry, pomegranate, boysenberry, plum, etc.
3) Sweetener- Look for low glycemic index sweeteners, such as Organic Blue Agave, stevia, etc- avoid all artificial sweeteners such as aspartame, sucralose, etc. And of course, avoid sucrose- sugar increases inflammation in the body amongst other things, and should not be a predominant sweetener.
Keep in mind all of the things above when looking at a product- you will be surprised at how many products you come across that do not meet all the criteria- put your antioxidant juice to the test and see if it meets the criteria!
