Groene thee extra gezond voor rokers
Onderzoeken hebben in het verleden al eerder aangetoond dat groene thee tegen kanker kan beschermen. Onderzoekers aan de Universiteit hebben nu ontdekt dat twee stoffen in groene thee beschermen tegen negatieve effecten van sigaretten roken.
“We did experiments with concentrations that would be present perhaps in one cup of green tea and that was very effective in blocking the effects of these tobacco smoke constituents,” says Thomas Gasiewicz, Ph.D.
The researchers tested extracts of green tea on the a-h hydrocarbon receptor – a key protein that tobacco relies on to cause cancer. Two of the tea’s potent chemical compounds – abbreviated e-g-c-g and e-g-c – shut down the toxic protein in the cancer cells of mice. Now there’s some evidence it may work the same in human cells.
“It’s hard to say what, how effective these concentrations could be in, in humans. So there’s still a lot more that needs to be done,” says Christine Palermo.
“We don’t really know how many cups would be effective against how many cigarettes that are smoked for example,” adds Gasiewicz.
