Thanks for the excellent review. I read the same JAMA study and many of the essentially click-bait links that sprang from it. I also checked other research and came to the same conclusion as you - but you've done the work and produced a very informative response. Thanks

PS I read through a bunch of studies on Semantic Scholar - most don't support the findings of the JAMA article https://www.semanticscholar.org/search?q=eggs%20saturated%20fat&sort=relevance
