I just replied to an EA member who raised the question "What is the most cost-efficient way to convert money into personal health?" so I thought I'll share it with you.
I'm pretty biased as a social psychology student, but some measures translates to health (physical and mental) better than cigarettes...the measure that was most correlated with longetivity was relationships and friendships (quantity and quality. It says Longest Study On Happiness but it's not only happiness, it's also longetivity).
So I guess find an affordable social hobby where you can meet new and good people.
Dancing, singing, martial arts (Capoeira is very social), ball games, off course, volunteering (socially). For me it's improvization. :)
And even cheaper (but as far as I remember, less effective than socializing, still more effective than not smoking) - avoid long sitting. Sitting is deadly. Stand up and make a little walk every once in a while.
No, my model of your view is that you were aware of the guidelines, but believe that sodium-reduction guidelines are on net harmful. Am I correct?
Both too little and too much salt is bad, but based on two the more recent meta-analyses I linked above, that deal with this controversy in the Ioannidis article you linked, I think the WHO salt reduction guidelines are on net good.
As a rule, public health messaging should be tell people to watch their salt intake to reduce their blood pressure, because:
pressure would be harmed because they adapt a very low sodium diet on the basis of sodium reduction guidelines
