Originally, goji berries (also called wolfberry berries) came to us from the northwest of China. These tiny pieces of fruit are normally exported as dried seeds which have a slightly sweet taste. Moreover, goji berries are known since thousands of years for their capacity to strengthen our immune system and fight against fatigue.
Nutrition-wise, goji berries containing some 18 kinds of amino acids out of which 8 are essential amino acids. They are also highly concentrated in antioxidants (beta-carotene and lycopene, essentially), and they contain minerals (including phosphorus, zinc, iron, selenium and copper), vitamins (A, B1, B2, B6, and C), and fibers.
Goji berries may be useful for fighting fatigue, for preventing any immune system weakness, for avoiding eye disorders, etc. Moreover, a number of Chinese researchers believe that these berries are among the foods that are likely to delay cellular aging. However, and despite the fact that they are full of useful substances, as we have just seen, scientists have not yet reached a unanimous agreement to confirm their efficiency vis-à-vis certain pathologies.
On the other hand, the problem which we could encounter with goji berries is their possible pollution due to the use of pesticides during their harvesting process. For this reason, it is always best to buy them as “Organic” products. Finally, goji berries must be kept away from air which can harden them excessively.
