Drinking eight ounces of mandarin orange juice a day might have the ability to decrease the risk of developing liver cancer, according to researchers in Japan.

Kyoto Prefectural University of Medicine researchers conducted a small one-year study involving participants with chronic viral hepatitis and found that none of those who drank mandarin orange juice developed liver cancer. In the group that did not drink mandarin orange juice, a small number of participants did go on to develop liver cancer. In the same study, researchers indicated that drinking mandarin orange juice might also have a positive health protective effect for atherosclerosis and insulin resistance.

Interestingly, Japanese researchers followed this inquiry after noticing that residents of a Japanese town noted for its high consumption of mandarin oranges suffered lower rates of liver disease, atherosclerosis and diabetes.

These findings, along with several others showing the health benefits of functional foods, will be presented during a four-day conference Functional Foods and Health, at the 232nd national meeting of the American Chemical Society.
