arises from my annual review of the medical literature. With the help of a team of hundreds of volunteers, we churned through tens of thousands of papers published in the peer-reviewed scientific nutrition literature and are ramping up to break new records in 2021. How do I choose which studies to highlight? In general, I strive to focus on the most groundbreaking, interesting, and useful findings; but which topics resonate the most? The practical ones, offering cooking or shopping tips? Or those that dissect the studies behind the headlines? Maybe it’s the geeky science ones exploring the wonderfully weird world of human biology? As you can see from the below list, the answer seems to be a bit of all of the above.
