I have tried to answer a question whether tea filters retain vitamins or minerals in tea.
When I wrote "The health benefits of green and black tea are mostly associated with their content of polyphenols" I apparently crossed a red line into health discussion that are to be avoided lest the site devolves into a pharmacy magazine style collection of doubtful health claims of certain foods. I understand that. The OP already skirted this with a question regarding minerals and vitamins which are not covered by the nutrient-composition tag which targets macro-nutrients (and has an explicit warning against tagging health-related questions with it).
While I'm probably more discussion- and comment-friendly than many others, I feel only ignorance and apathy regarding the health benefits of phenols and merely echoed common opinions. How can I make the answer (which I spent some time researching) publishable? For example, instead of referring to health benefits I can simply write "many people are interested in polyphenols that tea contains", simply omitting the obvious reason why they would be. Would something like that be sufficient?
I still feel that is should be possible to discuss stuff that's in food, and how it is affected by preparation. This is a cooking site, after all
