American specialists observed a group of 97 men who were diagnosed with High-grade prostatic intraepithelial neoplasia and atypical small acinar proliferation (both of these diagnoses indicate a high risk for prostate cancer).
During one year, on a daily basis, 49 men received Polyphenon E®, which contains a large amount of EGCG (200 mg/capsule) and a minimal amount of caffeine. The rest 48 men received a placebo. According to the results of the observations, the pharmaceutical formulation is well absorbed, but its use does not lead to changes in weight, body mass index and abdominal obesity, which are often associated with a decrease in the risk for prostate cancer. The scientists concluded that men who are obese and at high risk for prostate cancer should use effective weight loss techniques and avoid ineffective ones. The effectiveness of green tea, reported in previous studies, was attributed to the effects of green tea caffeine, which singly and in combination with catechins significantly increases energy expenditure.
