Cardiovascular risk: Low salt diets may be worse

There are a small number of people who are truly salt sensitive and should consume less salt. For the vast majority, it does not help and may be harmful.
While cultural factors have a huge influence on the types and proportions of foods that people eat, the one food item that is consumed in roughly the same proportion around the world is salt. Since the body regulates very tightly how much salt one consumes, a logical hypothesis is that people naturally want to eat the optimal amount of salt. Therefore, unless a specific medical condition exists, there is no reason to try to control the amount of salt consumed.
You are, innocently, spreading misinformation. This could lead some to give in to the temptation to consume sodium, which has a natural appeal to the palate.
