How to Make a Good Decision About Supplements

The proportion of our intervention pages that are supplements will probably go down a little bit. The reason is that supplement trials tend to be lower quality than almost any other kind of trial. And we should start relying a bit more on meta-analysis for those and overweighting meta-analysis and underweighting smaller trials. But the stuff that I personally find fascinating and that I always lurk on Twitter about and I don't participate is the proportion of plant and animal foods in someone's diet. When you can't, you'll never have a direct trial comparing these two.
