Despite the hype, a daily snack of a small handful of goji berries can be part of a healthy diet.
Because of the way that some of these plants and fruits have caught on in the past, companies will resort to hyperbole when explaining their products’ virtues. One Web site calls goji the “ hallelujah berry.” Others relate the story of a Chinese man named Li Qing Yuen, who allegedly lived to be 252 years old, and owed his longevity to goji berries. As previously stated, many companies claim that their goji berry products fight cancer, but others also mention cures for diabetes, glaucoma, diminished production of human growth hormone, sexual dysfunction and more. None of these “cures” have been proven.
Some companies have been warned by the FDA for marketing their goji berry products as “intended to prevent, diagnose, mitigate, treat, or cure disease” [ref]. According to the law, making such claims causes the products in question to fall under the category of drugs and subject to FDA approval. The FDA writes:
FDA is aware that Internet distributors may not know that the products they offer are regulated as drugs or that these drugs are not in compliance with the law. Many of these products may be legally marked as dietary supplements if claims about diagnosis, cure, mitigation, treatment, or prevention are removed from the promotional materials and the products otherwise comply with all applicable provisions of the Act and FDA regulations [ref].
Another factor to keep in mind regarding goji berries is the price. Usually these products aren’t cheap. A 32-ounce bottle of goji juice is at least $13. A 16-ounce package of dried goji berries is $15 to $22. A product called “Yogi Tea Green Tea Goji Berry Daily Energy Tonic” is $4.49 for 16 tea bags -- much more expensive than other green teas. You also might not be getting what you want: many juices that carry the name goji juice are actually a small amount of goji juice mixed with many other juices.
So are goji berries a good buy? They’re certainly healthy and can be a fun, new food to try. Along with a balanced diet and exercise, they can be a good part of a healthy lifestyle -- just don’t expect them to cure cancer or replace a visit to the doctor. And when eyeing goji berries in the supermarket or trying them for yourself, don’t forget about what may be the most important question of all: how do they taste? That is something only you can decide for yourself.
