High sodium intake may not lead to high blood pressure – unless you’re sodium-sensitive. But since it’s impossible to know who’s sodium-sensitive in advance, it makes sense to consume less than 2,400 milligrams of sodium a day – a little more than a teaspoon of table salt. This means avoiding highly salted processed foods, such as chips, crackers, and most canned soups. Another salt fact: a high sodium intake might reduce bone density.
