High-Selenium
Broccoli Stymies Some Cancers Science
Update was published in the April 2002 issue of
Agricultural Research magazine. John
W. Finley, USDA-ARS Grand Forks Human Nutrition
Research Center, Grand Forks, North Dakota; phone (701) 795-8366 Broccoli
stores selenium in an especially useful form (called SeMSC) that is easily
converted into an active anticancer agent. Now scientists have succeeded in
greatly boosting the selenium in specially grown broccoli. Earlier
studies showed that laboratory rats fed experimental high-selenium broccoli and
broccoli sprouts developed fewer precancerous lesions when exposed to known
carcinogens than did rats given selenium salts—either selenate or selenite.
The rats were fed the rough equivalent of a 200-microgram human dose of selenium
daily. The
new tests showed that high-selenium broccoli sprouts protected the rats against
precancerous lesions in the colon, while high-selenium broccoli protected
against mammary tumors. Specially
produced for this research, the experimental broccoli heads and sprouts used in
these studies aren't available commercially. And further study is needed to show
whether these findings will also prove true in humans. |
