Episode 48: Alcohol

The Studies Show Podcast

Okay, it’s time to finally answer the question: is drinking booze good or bad? Is there really a “J-curve”, such that it’s bad to drink zero alcohol, good to drink a little, and then bad to drink any more than that? What exactly is the “safe level” of alcohol consumption, and why do the meta-analyses on this topic all seem to tell us entirely different things?

In this episode of The Studies Show, Tom and Stuart get very badly intoxicated—with statistics.

Show notes

• Media reports say alcohol is good! Oh no wait, it’s bad. Oh, sorry, it’s actually good! No, wait, actually bad. And so on, ad infinitum

• The three conflicting meta-analyses:

  • 2018 in The Lancet (“no safe level”)

  • 2022 in The Lancet (the J-curve returns)

  • 2023 in JAMA Network Open (using “occasional drinkers” as the comparison)

• Some of the press coverage about the J-curve age differences

• David Spiegelhalter’s piece comparing the two Lancet meta-analyses

• Tom’s piece on the idea of “safe drinking”
