Broccoli en rode pepers remmen kanker.*
Uit twee studies blijkt dat zowel broccoli als
rode pepers kanker kan remmen. Gekeken werd naar de effecten van deze
voedingsmiddelen op baarmoeder- en pancreaskanker, twee soorten met minder goede
vooruitzichten.
In de rode pepers bleek vooral de stof capsaicine,
die de hete smaak geeft, de anti-kanker werking
veroorzaakt. De werkzame stof in
broccoli en ook andere kruisbloemigen is phenethyl isothiocyanaat.
Broccoli, Red Chili Pepper May Slow Cancer Tumors: Study
Dietary agents in
red chili pepper and broccoli may help fight cancer
by slowing or preventing the growth of cancerous tumor
cells, say two studies presented at the annual meeting of the American
Association for Cancer Research.
The studies
investigated the effect that these dietary agents had on two types of cancers
that have poor prognoses.
"In our
studies, we decided to look at two particular cancers -- ovarian and pancreatic
-- with low survival rates, to ascertain the contribution of diet and nutrition
to the development of these cancers. We discovered that red chili pepper and
broccoli appear to be effective inhibitors of the cancer process," lead
investigator Sanjay K. Srivastava, an assistant professor in the department of
pharmacology at University of Pittsburgh School of Medicine, said in a prepared
statement.
The first study
found that capsaicin, the "hot" ingredient in red chili pepper,
exhibited anti-cancer activity against pancreatic cancer cells.
"Our results
demonstrate that capsaicin is a potent anticancer agent, induces apoptosis (programmed
cell death) in cancer cells and produces no significant damage to normal
pancreatic cells, indicating its potential use as a novel chemotherapeutic agent
for pancreatic cancer," Srivastava said.
The second study found that phenethyl isothiocyanate (PEITC), which is found in cruciferous vegetables such as broccoli, showed cancer-fighting properties when tested on ovarian cancer cells.( Mei 2005)
