I disagree, as this is the right type of study result—something a common person can practically do with a common objective test they get from a common physical to show a common supplement or food (salmon) is effecting beneficial change.
In terms of establishing an individual’s required intake as part of comprehensive changes under the guidance of a professional, I agree.
But to a layperson such benefits are wholly lost due to other personal choices - even a single choice - and at that point it falls under the grandiose shell game hawking fictional health benefits for corporate profit.
