No doctor here - not even a health care worker. Just someone who has seen friends and close family members deal with cardiac-related issues.
When someone easts a controlled diet - and see cardiac-related edema decrease - then see the edema return after one difference - too much salt... what are we suppose to think?
That’s common among older people whose hearts are failing.
I think the article is addressing younger, healthier people.
I don’t think the argument is really any individual’s choice. If someone believes low sat is helping, then by all means go low salt. The real question is whether the gov’t should regulate salt. That answer should be clear.
In previous centuries, physicians depended on guesswork, experience and tradition. If the leaches were applied and the patient recovered, it was because of the leaches. If the patient died, it was because not enough leaches were applied, or patient would have died sooner without the leches. You can always mold your conclusion to fit your preconceived ideas.
