"Researchers from Johns Hopkins and China's Qidong Liver Cancer Institute tested the effects of a tea made with broccoli sprouts among 291 residents of Jiangsu Province, an area of China that which has some of the worst air pollution in the country. The study showed that a daily drink of a half cup of the tea - a combination of freeze-dried broccoli sprout powder, water and pineapple and lime juice - increased elimination of by-products of the cancer-causing toxin benzene by 61 percent, and boosted excretion of acrolein, a lung irritant, by 23 percent. Increased elimination of these substances began immediately after the participants began drinking the tea and continued at the same rate through the study."
