The benefits of goji berries

Goji berries have an A-list status and are used in Chinese medicine for more than 6,000 years.

According to a study conducted along with the British Dietetic Association (BDA), these popular fruits among celebrities are supposed to help your immune system and brain activity, help you fight against cancer, heart disease and improve your life.

They are high in vitamin C, vitamin B2, vitamin A, selenium, iron and numerous antioxidants.

Regarding the effect that goji berries may have on the immunity, there are no studies or hard evidence to support the claim, but as for brain activity and digestion, a study conducted in 2008 showed that a daily dose of 120 ml of juice in a two-week diet can help brain activity, digestion and the overall wellbeing. The study was too small and its results can’t be considered conclusive.

The results on how goji berries can help in the fight against cancer were also inconclusive because even though some patients with advanced cancer reacted well to immunotherapy in combination with goji polysaccharides, there is no data regarding the compound used and the design of the study.

Alison Hornby, a dietitian and BDA spokesperson, said that there is no strong proof to support the numerous claims on the benefits of goji berries.

She says: "Various goji berry products are sold as health foods, but the evidence of their health benefits so far comes from scientific studies using purified extracts of the fruit at much higher concentrations than the products contain. 

"As these products tend to be relatively costly, it makes sense to stick to eating a range of fruits and vegetables rather than spending your money on this one item with no proven health benefits."
