According to a recent small study, regular eating a handful of dried goji berries may help delay or even prevent the onset of age-related macular degeneration (AMD) in healthy middle-aged people. AMD happens when aging causes damage to the macula, the part of the eye that controls sharp, straight-ahead vision.
The study showed that 13 healthy participants aged between 45 and 65, who ate 28 g (appr. 1 oz) of goji berries 5 times a week for 90 days, increased the density of pigments, lutein and zeaxanthin, in their eyes. Both pigments help to protect the eyes during aging by filtering out harmful blue light and providing antioxidant protection. Contrary to these 13 participants, another group of 14 study participants who consumed a commercial supplement for eye health over the same period, didn’t show an increase.
The researchers explained that big amounts of lutein and zeaxanthin in goji berries are present in a highly bioavailable natural form so that our body can directly absorb and use them.
Whether eating goji berries help people in their early-stage of AMD is a question for further investigation.
