Prostate cancer is a serious health problem for men around the world. Doctors know that things like being overweight, having high cholesterol, and a high PSA blood test result can increase the risk.

In some parts of West Africa, where people drink a lot of green tea, prostate cancer is less common. Scientists wanted to see if green tea might be helping to lower the risk.

The researchers led by Dr. Emmanuel Amankwah Ntim at the Department of Physiology, KNUST School of Medical Sciences studied over 400 men, aged 40 and older, and split them into two groups: those who drank green tea and those who didn't.

They checked their weight, cholesterol levels, and PSA (a protein linked to prostate cancer).

The findings published in the Journal BMC Nutrition concluded that men who regularly consumed green tea were more likely to maintain a healthy weight and exhibit healthier cholesterol levels.

Furthermore, older men, specifically those aged 60 and above, demonstrated lower PSA levels, indicating a potential reduced risk of prostate cancer, with this benefit not observed in younger men, and among these older men, a correlation was observed between lower weight and lower PSA levels.

The study suggests that drinking green tea might help lower the risk of prostate cancer in older men, as well as improve weight and cholesterol levels.

However, it is important to note that this study shows association and does not prove that green tea directly causes the lower risk.
