What was updated?
In short: everything.
But some sections have changed more than others.
Two sections have been greatly expanded:
● The one on glucose metabolism;
● The one on exercise performance.
Two brand new sections have been added:
● One on bone and joint health;
● The other on aesthetics (topical green tea appears surprisingly effective against acne).
In addition, the whole document has been reorganized to reflect the format of our more recent supplement pages; it is now easier to read and navigate. Several studies have been added, and a few studies not on tea but on related topics (e.g., catecholamines) have been replaced by more appropriate studies whenever any had become available.
Research on the antioxidative properties of green tea isn’t as strong as you might believe. Most studies on the topic are in vitro studies, and most of the human studies measured biomarkers that may not interest you (e.g., malondialdehyde). Still, since most people know green tea as an antioxidant, care has been taken to mention those studies whenever appropriate in any given section.
