Chlorophyll Can Help Prevent Cancer -- But Study Raises Other Questions
January 18, 2012 A recent study at Oregon State University found that the chlorophyll in green vegetables offers protection against cancer when tested against the modest carcinogen exposure levels most likely to be found in the environment.
However, chlorophyll actually increases the number of tumors at very high carcinogen exposure levels.
Beyond confirming the value of chlorophyll, the research raises serious questions about whether traditional lab studies done with mice and high levels of toxic exposure are providing accurate answers to what is a real health risk, what isn't, and what dietary or pharmaceutical approaches are useful.
The findings, published in the journal Food and Chemical Toxicology, were done using 12,360 rainbow trout as laboratory models, instead of more common laboratory mice. Rodent studies are much more expensive, forcing the use of fewer specimens and higher carcinogen exposures.
