Why is it so hard to eat healthy? Well, it surely does not help that it's so unclear what healthy food is.
This video makes fun of the ping-pong game that is our ever-changing dietary advice.
The reason? It's very hard, expensive and time-consuming to prove what food is truly good for us. Lacking any firm evidence the field of nutrition uses weak statistical clues from observational studies. Those can basically "prove" anything, leading to constantly changing advice after every new study.
The solution? Admit all that we don't know, and stop pretending that weak statistical correlations prove anything.
