Prostate cancer, especially prostate cancer risk, has been linked to both genetic and environmental factors. Of the environmental factors, diet is a major concern.
The consumption of both tea and coffee, which are two of the most popular beverages in the world, have been evaluated for effects on health outcomes, including cancer. Despite all the research into dietary questions and the popularity of tea and coffee, there has been little guidance given to the public on the consumption of these drinks.
In a paper from The School of Public Health, Curtin University of Technology, Perth, WA, Australia ,written by Lee AH, Fraser ML, Binns CW., the relationship between the consumption of tea and coffee and prostate cancer has been examined.
For those coffee drinkers among us, there is good news. Current evidence from this study indicates that coffee is a safe beverage and its consumption probably has no relationship with prostate cancer development and its recurrence. However, tea, especially green tea, has shown some potential in the prevention of prostate cancer (and maybe prostate cancer recurrence) and should be considered a more desirable drink. (Strong evidence of the positive effect of green tea comes only from animal and in vitro studies.)
The take home message – Tea, especially green, is a better alternative to coffee.
