Wine and chocolate are great and horrible
I’ve had a personal morbid fascination with the medical literature since medical school. I’ve lived long enough to see several things be portrayed in the professional and layperson literature as miraculously beneficial treatments only to be the polar opposite in the next study or after failing to be replicable long term. It’s nuts. I’m not a statistician but I’ve been trying to become more facile with statistics (I highly recommend this amazing little book) and especially the many kinds of bias that can influence the “conclusions” of studies.
