ANTIOXIDANT PROPERTIES OF GOJI BERRIES
Antioxidant power of goji berries
Noteworthy for their popularity as an antioxidant food, goji berries deserve some lines to discover their true antioxidant power.
Carotenoids, vitamins, polysaccharides, and in general all the Goji phytochemicals confer these fruits antioxidant properties. However, it it is not commonly known whether these effects are truly exceptional, or if they are common in other vegetables, fruits or plant foods.
Therefore, the National Institute on Aging (NIH) has developed the ORAC scale (Oxygen Radical Absorbance Capacity). The ORAC scale is a measure of the antioxidant power of foods. This scale lets us compare the different foods.
ORAC scale gives Goji berries 3290 ORAC units per 100 g. That's an important valule, However, as discussed in the following paragraph, many plant foods in the world offer us a similar range of possibilities with the same properties.
This may be enough to break the belief or myth that has been created around this food. Goji berries certainly possess antioxidant properties but there is no better medicine than a balanced and varied diet, which includes plenty of vegetables to benefit from all their natural nutrients.
The following chart compares the ORAC values of goji berries with other foods.
It must be considered that the ORAC scale only measures antioxidant potential of food in a test tube by laboratory tests and ignores the complexities of the human body and the reactions in vivo (there are many factors involved in the reactions of the body, so it is impossible to reproduce in artificial media such as test tubes).
It is known that many of the antioxidants in foods, particularly fruits and vegetables, require the presence of another substances to be absorbed, if not provided through a varied diet, these substances are wasted or lost in the gastrointestinal tract.
For this reason, once again, we must insist that a varied, balanced diet rich in fresh fruits and vegetables provide the best benefits and guarantees us to be well nourished.
