The three-month long study included about 300 Chinese men and women living in one of the most polluted areas of China, a rural community in the Jiangsu Province.
The test group drank half a cup a day of a beverage consisting of sterilized water, pineapple, and lime juice, with dissolved freeze-dried broccoli sprout powder. The control group drank the same mixture without the addition of the sprouts.
After urine and blood tests were collected and analyzed, the researchers found that the test group, who received the broccoli sprout powder, excreted far greater levels of two carcinogens. Excretion of benzene increased 61 percent, and the rate of excretion of acrolein increased by 23 percent.”
