Frequently Asked Questions
Are goji berries carcinogenic?
Eva De Angelis, a dietitian nutritionist, says, “Goji berries have always been commonly used in traditional Chinese herbal medicine. They’ve also been labeled a superfood because of their high concentrations of bioactive compounds like polysaccharides, polyphenols, flavonoids, and carotenoids. Most of these compounds have the potential to be powerful allies in the fight against cancer.”

According to Eva De Angelis, a dietitian nutritionist, “Like any other crop, goji berry plants are treated with pesticides, which may be harmful to human health. Plus, some heavy metals could be absorbed by the plant, but the content is different for different areas of the world. Yet, there is insufficient evidence to suggest that this is the case, so eating goji berries does not pose a carcinogenic risk.”
