Doctors have long said eating too much salt can negatively affect a person’s health, but a new study shows not enough salt can also have an impact.
The average American consumes about 3,400 mg of salt, or about a teaspoon, per day. The Centers for Disease Control and Prevention recommend less than 2,300 mg per day, but the new study in the American Journal of Hypertension suggests that number is too low.
The average sodium intake range should roughly be between 2,600 mg and 5,000 mg per day, the collaborative study from Albert Einstein College of Medicine and the Copenhagen University Hospital shows.
Salt intake within that range showed a decreased rate of cardiovascular disease and mortality, researchers said.
“Both low sodium intakes and high sodium intakes are associated with increased mortality,” the study concludes. “Sodium reduction, moreover, produces several physiological effects, some of which may adversely influence health outcomes.”
The group analyzed data from 25 different sodium studies and determined that a larger intake range than previously thought is acceptable for sustaining good health.
