Hi,
I remember I started on Wikepedia to get an good idea of all the options and followed links to drill deeper. From there, I went and read lots of research studies on PubMed website. I also found 2 good videos to watch and share with my spouse from UCSF. All links are below.
In general, it is in your best interest to dive all in into the current research. This is a topic that is not heavily researched and new studies are coming all the time, albeit at a slower pace than what I wished.
