Eating lots of salt -- and not enough potassium -- is a recipe for heart problems.
A new study published in the Archives of Internal Medicine looked at the health records of more than twelve thousand adults.
It found the more sodium a person had in their diet the higher their overall risk of death. Men, young adults, and smokers were more likely to fit in this category.
On the other hand, having high levels of potassium in the diet was linked to a lower risk of death.
The researchers say more efforts need to be made to lower the amount of sodium in food, especially processed food.
