Green Tea is healthy, the caffeine in green tea is not. As a result, you would get the most benefit from the pill form which has the extract of EGCG, but not from the tea form which contains the caffeine. The unhealthy caffeine will cancel out whatever the healthy component is.
So science has always been clear, the coffee bean and green tea both have something in it which is healthy, which is associated with longevity, but the caffeine is really bad and for people with certain genetic predispositions it can cause diseases like diabetes by way of insulin resistance.
Thanks for commenting.
I would strongly disagree with that. This is an example of the previous thinking that resulted in the idea that coffee is universally bad.
For example in the study you cite:
Nobody takes caffeine intravenously and few people take it in isolation. Putting aside the fact that the sample size is tiny this alone makes me very dubious about the applications of this research to real life. This doesn't really say anything about the caffeine in green tea which is actually similar to levels in decaff coffee.
Agreed. It is common sense too. The raw unprocessed form of these foods are as in most cases the healthiest form.
Exactly. It seems to vary from individual to individual. It is not harmful for most people when taken as part of a beverage such as coffee or tea and may even have beneficial effects but it is not good for everyone. Also taking huge quantities as are present in some energy drinks may be a bad idea. As always common sense is required.
Parse what I wrote. Caffeine is universally bad not coffee. There is no health benefit to caffeine consumption.
We disagree on this. Most people in the United States die of heart attack and stroke, and also consume caffeine. Many people get diabetes, and also consume high fructose corn syrup. While I cannot prove definitively that caffeine causes the heart attacks and strokes, it seems to increase the risk factors. In addition it speeds up the metabolism in a way which would create more free radicals, and this according to some lines of thinking would accelerate aging. Caffeine doesn't seem to be worth the risk even if a person doesn't get sick from it.
I would disagree with that. Few things are universally bad.
Not necessarily. I would not want to make such declarations without extensive research.
That is your perception but I think you miss the point of the article. Whatever you think of caffeine it is safe to take as part of coffee.
