No.
Back in the early '90s I read about the definitive study of salt use by humans. It was conclusive. Salt intake had no adverse effect on healthy people.
This was an exhaustive worldwide study sampling all groups. It confirmed what people have known for more than recorded history; salt is necessary to health, and the body will rid itself of excess salt using only what it needs.
Of course, this study barely saw the light of day. As with the rest of popular nutrition, we have allowed fanatics to turn us away from healthy eating habits.
WE have recently seen, finally, the turn around in the debate about fats and carbs. Even though 40 years of science had pointed in the right direction, the momentum against fats and pro-carb was considerable. Too many scientific debates are being handled this way..
