YSK that taking health advice from youtubers, celebrities and podcasters is a terrible idea.

This is mostly correct. Huberman, for example, is not a good source. But Rhonda Patrick seems decent.

Only take advice from research universities

This is not great advice. I’ve seen so many articles on sites like Harvard that contain harmful misinformation and no study citations.

Always look for citations to studies. But even that is not enough. The source can be cherry picking to push an agenda, or simply ignorant of other conflicting research. You really have to put a lot of effort in to find quality sources.

It’s not easy to find quality information, but sites like sciencedirect, eurekalert, and medicalexpress, are some of the better sources.
