Healthy subjects who received daily caffeine-free green tea extract capsules had an increased production of detoxification enzymes, which may provide some cancer-fighting benefits, study findings show.
“Concentrated green tea extract could be beneficial to those who are deficient in the detoxification enzyme and shouldn’t be harmful for those who have adequate detoxification enzyme,” lead investigator Dr. H.-H. Sherry Chow, of the University of Arizona, Tucson, told Reuters Health.
Boneheaded. Let me tell you why. First, we already went over how green tea supplements are actual pro-oxidants not anti-oxidants. So what’s going on with the Rueters statement? If you look at the study ($ requrired), what they found was if they have a supplement of polyphenon E (containing 800 mg EGCG), the participants had increased production of an enzyme called GST that helps to detoxicify your liver and thus your body (that’s really broad and general, and I actually hate the word detoxicify but we’ll stick with it). The thing is, Why would your body ramp up production of detoxifying enzyme. Maybe because it’s under toxic attack? Why yes! Specifically, GSTs are induced by oxidative stress in the liver, which is exactly what we know EGCGs do. So the GST pool is higher because the stress is higher; when the stress goes down, the GST does too. So we really don’t know whether the GST reserve is any better or not. So does this sound like a good thing for your body to go through? No.
Simply put, the authors’ conclusions are the equivalent of stepping outside your house and seeing military troops all over the place, armed to the teeth and coming to the conclusion, “My what a peacefull day, look at all the protectors around”. They’re there for a reason, and that reason isn’t likely to be good.
