A study conducted by US researchers shows that taking chlorophyllin could greatly reduce the levels of aflatoxin-DNA damage byproducts in the body, indicators of exposure to carcinogenic aflatoxins and an increased risk of liver cancer. Chlorophyllin is a derivative of chlorophyll and is used as an over-the-counter dietary supplement and as a food colorant. "Our study shows that taking chlorophyllin three times a day reduced the amounts of aflatoxin-DNA damage by 55 per cent, compared with taking a placebo,"​ says Thomas Kensler, PhD, professor of environmental health sciences at the Johns Hopkins Bloomberg School of Public Health. "Taking chlorophyllin or eating green vegetables, like spinach, that are rich in chlorophyll may be a practical way of reducing the risk of liver cancer and other cancers caused by environmental triggers,"​ explains Dr. Kensler. Dr. Kensler and his colleagues conducted a double-blind study among residents of Qidong, China. The people of the region have a very high rate of liver cancer, which is due in part from routinely eating foods contaminated with carcinogenic aflatoxins. The aflatoxin is produced by molds found in foods like corn, peanuts, soy sauce, and fermented soybeans. For the study, researchers recruited 180 healthy adults. Half of the group was given 100 mg tablets of chlorophyllin to take three times a day with meals for four months. The other half was given a placebo. Urine and blood samples were taken over four months to determine the effects of chlorophyllin on excretion of aflatoxin-DNA damage products. According to the study's results, the people who took chlorophyllin showed a 55 per cent reduction in aflatoxin-DNA damage, compared to the placebo group. "Studies conducted by our co-author, George Bailey of Oregon State University, have suggested that chlorophyllin acts as an 'interceptor molecule' to block the absorption of aflatoxins and carcinogens in the diet,"​ explains John Groopman, PhD, professor and chairman of the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health. "Our study shows that chlorophyllin can effectively reduce aflatoxin levels, which should reduce the risk of liver cancer. Since chlorophyllin is found in many foods or can be easily added to the diet, it could be a safe and effective prevention method. The study adds to the evidence that green vegetables contain effective anticarcinogens,"​ adds Dr. Groopman. Follow up studies are planned to determine whether this early protective action of chlorophyllin extends to either delay the onset or reduce the incidence of liver cancer. Full findings are published in the November 27, 2001 edition of Proceedings of the National Academy of Sciences.
