On contradictory food studies

Paul Taylor at the Globe and Mail – Why do researchers churn out so many contradictory food studies?:

Food studies frustrate me. One week a study says one thing. The next week another study says the opposite. Why do researchers churn out so many contradictory studies – and why does the news media keep covering them?

Taylor covers the various research methods well, but doesn’t discuss the media’s culpability in promoting findings that aren’t really there.

Dr. Donald Redelmeier gives good advice:

For that reason, Redelmeier says the best thing to do is focus on having a lot of variety in your diet – “everything in moderation” – and don’t get distracted by contradictory studies and the latest food fads.
