A fruit rich in antioxidants
No wonder when you look at their composition, rich in trace elements, vitamins and antioxidants. Goji berries thus have a very high proportion of carotenoids which participate in the fight against free radicals.
They would also contain no less than 21 trace elements (zinc, iron, selenium, phosphorus), 18 kinds of amino acids, calcium, numerous proteins and vitamins E, B1, B2, B6 and C. In short, a " super-food ”which would provide many nutrients necessary for the proper functioning of our body!
Goji berries are used by Chinese herbalists to fight fatigue, respiratory ailments and male infertility. They would also have a protective action on the liver and kidneys and would stimulate the immune system while slowing cell aging.
A marketing operation?
Goji berries have been exported to the West in recent years and are now enjoying growing success. Marketed mainly in dehydrated form, they are sold in organic stores or on the internet. Prices vary: from 20 to 40 euros per kilo.
Recently, the berries have also been cultivated in France and sold fresh on the shelves of our supermarkets. This is good news because this freshness guarantees the good preservation of their properties.
If goji berries are popular, the benefits of small red fruits are now questioned by scientists who denounce a marketing effect and the lack of studies proving their real benefits.
In addition, goji berries cultivated in Asia are said to contain many pesticides and are the cause of strong allergic reactions in some consumers. A "super-food", perhaps, but to be consumed with caution ...
