In your experience as a health expert. what have you learned are the pros and cons of drinking coffee ?

Conflicting studies: There have been many research studies on the health effects of coffee with very conflicting results- some find it may be harmful, others find benefits. I believe large amounts of coffee are likely harmful but 1-2 cups a day is probably safe. People react variably but if you enjoy it use in moderation.
