Whether this research stands the test of time or not, it reminds me a lot of the American Heart Association's stance on salt, which is very problematic. They recommend less than 2500 mg/day, which study after study shows is associated with increased all-cause mortality. They do it because they know that people with salt-sensitive hypertension already live unhealthily, and if they recommend a ridiculously low amount of salt, then maybe people will only ingest 2-3 times the recommendation (at least this is my assumption about why they do it). The problem is that the scared, nutritionally conscious take this stuff to heat and say that "if 'science' says so, then it must be true", and the people they want to be paying attention just really don't care.
