Goji berries have been grown and imported from China for over 20 centuries because of the so-called health benefits of the berries. Goji berries have been known to treat a great deal of ailments according to Chinese and Asian culture. These berries either dried or fresh are filled with over 18 kinds of amino acids and over 21 minerals and vitamins mostly vitamin A, B & C. According to wedmd.com, goji berries have high levels of antioxidants that help protect the liver, eyesight, immune benefits, skin benefits against the sun, protects developing antiaging diseases and can be anticancer. Three studies were done to see if goji berries are really the superfood the Chinese and Asian culture has said it to be.
Many people think goji berries benefit eyesight because they are high in antioxidants (Bucheli, 2010) the first study was a 180 days a study was where 75 elderly people got the goji berry, and the other 75 randomly got a placebo. Each group of elderly people was tested to see if a goji berry supplement would reduce the risks of developing a disease affecting their eyesight from old age, but that was slightly in their eyes already. After the 180 days of the study,13 subjects in the placebo group showed the progression of macula hypopigmentation causing slight blindness in the eyes but the people who received
the Goji berries, supplements showed much less macula hypopigmentation than what they started with. (Bucheli, 2010) Another study was done in healthy adults measuring their eyesight, too, but it showed no effect on visual activity because there was nothing wrong with their eyesight in the first place (Bucheli, 2010) however, their antioxidant levels did increase. Anticancer studies have not been tested on humans, but male lab rats with prostate cancer were feed dried goji berries daily to see if there were any effects. The results of the study showed that the goji berries killed the cancer cell growth in the mice and found less amount of cancer cells in their bodies. (Environmental Nutrition, 2010)
Other heath benefits that the Chinese also thought that came with the daily intake of goji berries is mental health like calmness, sleeping, increased energy and being able to focus better through the day (O’mathúna, 2010). A study was done (O’mathúna, 2010) to 34 healthy people randomly picked either drink goji juice or drink a placebo juice and each subject was questioned before the study and after. The studied concluded was that over the time of the study the people who drank the goji juice had increased scores in calmness, sleep quality, ability to focus and feelings of happiness.
