man’s best friend…especially his prostate

While in western countries every sixth man will develop prostate cancer in his lifetime, this cancer is much rarer in Asia. Studies suggest that regular consumption of green tea by Asians may partially explain this difference.

We know that nearly a third of men by the age of 40 already have microscopic tumors in the prostate. Even though these microtumors are harmless, they can still progress in the decades that follow and reach the stage of a full-blown cancer that threatens survival.

Men are therefore constantly at risk of developing prostate cancer, and one of the major research challenges is to identify strategies that target these microtumors in order to prevent them from acquiring the properties necessary for their progression to the cancerous stage. .

Half a cup of cruciferous vegetables a week lowers the risk of prostate cancer by 45%

Such a preventive approach is particularly important as we now know that the progression of these microscopic tumors can be halted with a good lifestyle, particularly a good diet, regular physical activity and maintaining a normal weight.

A diet rich in cancer-fighting plants like cruciferous vegetables and tomatoes seems to play a particularly important role: Studies show that men who eat more than 1/2 serving of cruciferous vegetables (broccoli, cauliflower, Brussels sprouts) per week lost around 45 % lower risk of prostate cancer than those who eat it less than once a month.

This protective effect is also around 25% for those who eat a lot of tomatoes (2). Therefore, switching the diet to include these foods, which are rich in anti-cancer molecules, represents an extremely promising strategy for preventing the development of prostate cancer.

Green Tea: Its molecules block the development of prostate tumors

Even though studies show that a significant proportion of Asian men have microtumors in the prostate, these men still have a much lower incidence of cancer of this organ.

In other words, Asians appear to have the same risk as Westerners of developing this cancer, but certain aspects of their lifestyle prevent microtumors from developing into mature cancers.

The copious consumption of green tea by these men might explain this paradox; In fact, previous studies have shown that giving the anti-cancer polyphenols in green tea to volunteers with early-stage prostate cancer caused a significant reduction in tumor development.

Green tea improves life expectancy

Recently, researchers have proven that this chemopreventive effect is likely due to a polyphenol, EGCG, the main anti-cancer molecule in green tea. This molecule has the ability to block the function of the androgen receptor, a protein that is very commonly expressed in prostate cancer cells and plays a crucial role in the progression of the disease.

EGCG’s inhibitory effect on this protein could be particularly useful as an adjunct to the anti-hormonal approaches currently used in advanced prostate cancer: when these aggressive tumors become resistant to hormone therapy, therapeutic options are indeed few and death can occur within one year occur. Therefore, the effectiveness of EGCG in green tea against the androgen receptor could prevent the progression of these tumors and thereby improve the life expectancy of patients.
