Goji Berries – A true superfood

  • icon
  • Goji berries, also known as wolfberries or lycium fruit, are a member of the nightshade family which contains many other common vegetables such as tomato, eggplant and pepper. They are considered to be among the most nutritionally dense fruits on earth, so it’s no surprise that they have gained a huge popularity over the past few years.

    Goji berries have been used for thousands of years in Tibet and China as an important part of traditional medicine and medical diets.

    Health boosting properties

    In the last decades, a large number of lab and animal studies have been conducted with goji berries. From these studies we know that a number of natural components isolated from goji berries have multiple pharmacological properties, including antioxidant, anti-aging, immune boosting and anticancer activity. Also they are known to have blood pressure lowering effects, to help in body fat reduction and to protect hepatic function (1,2).

    Goji berries score among the highest for their antioxidant activity compared to other fruits and vegetables (3).    

    Basic Nutrition Facts

    ¼ cup of goji berries (30 gr.) gives you around 90 calories and 4-5 gr of protein which is surprisingly high for a fruit.

    Cancer Protection

    The two major active ingredients in goji berries, LBP and AA-2βG, a vitamin C analogue, were found in studies to lead cancer cells to death and to enhance the effects of other cancer therapies (4).

    Goji berries were shown to have synergistic actions with chemotherapy and radiation and to reduce their side effects (5). Animal studies which have shown that LBP from goji berries enhanced the effects of radiation to acute cells of lung cancer (6). Also in another animal study, goji berries were found to reduce cardiotoxicity associated with the chemotherapy drug, doxorubicin (7).

    Ways to enjoy your berries

    People eat goji berries raw, dried, or dried soaked first in water. Be creative in finding your favorite ways for enjoying goji berries. Add them in salads, smoothies, trail mixes, on top of your muesli or other cereals, yogurt etc.

    Avoid goji berries if you are taking anti-coagulant medication

    People taking anticoagulant therapy such as warfarin should avoid regular use and high doses of goji berries or goji juice. A few cases of elevated INR in patients on anticoagulant therapy were reported following consumption of concentrated Chinese herbal tea made from goji berries.
