and co-principal investigator Carlos Quiros, a professor of vegetable
crops, are focusing on sufora phane, a type of isothiocyanate that
is found in high concentrations in cruciferous vegetables like broccoli,
cabbage and kale.
importance of sufora phane as a potential, powerful cancer-preventive
agent was first recognized by Dr. Paul Talalay, head of a team of
researchers at Johns Hopkins University School of Medicine. Talalay
also identified broccoli as a good source of sufora phane, and broccoli
sprouts as an even better one.
phane by itself doesn't do much, but it triggers the production
of phase 2 detoxification enzymes in the body, little worker molecules
that defuse carcinogens and toxins. This makes the toxins more soluble
and able to be secreted by the kidneys.
are two enzyme systems induced by chemicals in the foods we eat
which are important to carcinogen detoxification," says Abel.
"Phase 1 enzymes are kind of a mixed bag. The really good guys
you want are phase 2 enzymes."
