Salt connected to obesity?

I’ve always said that the research on salt is complicated, not least because it is so difficult to separate out the effects of salt itself from the junk food company it keeps.  So a new British study provides some confirming evidence: kids who eat a lot of salt also drink a lot of soft drinks.  Guilt by association!  The effects of salt on hypertension also might be influenced by everything else in the diet.  That’s why it’s so difficult to make sense of research on one dietary factor at a time.
