There are plenty of other sources for polyphenols - including tea, but also chocolate, qinoa, buckwheat etc.
There is no need to drink coffee in order to replenish polyphenols in your body.
And drawbacks are huge: aside from broken sleep, caffeine puts a giant strain on cardiovascular and other systems, and in people with caffeine addiction, not having their cup leads to high irritability, sleepiness, dizziness, and a lot of other symptoms.
There are plenty of studies displaying improved cardiovascular health in those who drink 1-4 cups of coffee a day.. Generally, cardiovascular risks of caffeine from coffee are not important for the average person’s health decisions.
Also tea has caffeine as well (technically dark chocolate too, but less than tea so not really a concern).
And again, the solution to sleep issues are to not have caffeine (tea, coffee, or otherwise) more than a few hours after you wake up.
Withdrawal symptoms are not a major concern - they are temporary at best.
Edit: there are plenty of sources of polyphenols - but frankly the average American does not get nearly enough generally. If you have a typical American diet, I would not recommend quitting coffee as a health measure unless you have already drastically increased consumption of polyphenols generally.
Alright, thanks for fair criticism! Will delve deeper.
