Narrator: This is Science Today. Eating your greens not only provides beneficial vitamins and minerals, but it could also save your life. Researchers at the Lawrence Livermore National Laboratory found that giving someone small doses of chemicals found in leafy greens such as spinach, broccoli and kale can reverse the effects of aflatoxin poisoning. Lab scientist Ken Turteltaub says aflatoxin is a potent, naturally-occurring food toxin that's associated with the growth of mold.
Turteltaub: And aflatoxins in laboratory animals cause liver cancers and so there's been a concern that exposure to aflatoxin may contribute to human liver cancers.
Narrator: The researchers fed a group of volunteers a small dose of aflatoxin and found that small doses of chlorophyll and chlorophyllin found in leafy greens significantly reduced aflatoxin absorption.
Turteltaub: It showed that in fact the chlorophyll and chlorophyllin in people could reduce the amount of aflatoxin that is potentially damaging to people by anywhere from 40 to 60 percent. So, this opens the door for ways to modify and try to reduce risk.
