I really appreciate that you thoroughly researched this topic and added all the citations at the bottom to boot! I would argue that one key thing your article failed to touch upon is micro-plastics and the potential harms caused by the ingestion of these microscopic particles!
This would be why I personally stay away from fish — as there are other ways to obtain the nutrients you need from plants whilst simultaneously avoiding the microplastics (and mercury, come to think of it!)
Thanks for sharing!
