One odd aspect is that all these 'recommendations' adopted en masse (low salt, low cholesterol, low fat) are based on the goal of avoiding heart problems. I guess it makes sense as a goal but not sure it makes sense to go in reverse from that goal, using very unsound studies, to come up with these restrictive rules of thumb for everyone... like oh, just reduce the salt in this meal and you'll be okay. Indeed such approaches can be described as superstition.
