Salt intake of less than 5 grams per day for adults helps to reduce blood pressure and risk of cardiovascular disease, stroke and coronary heart attack. The principal benefit of lowering salt intake is a corresponding reduction in high blood pressure.
Is low salt bad for you?
Though health authorities continue to push for lower sodium intakes, reducing sodium too much — below 3 grams per day — may negatively impact health. Studies show that people who consume less than 3 grams of sodium per day are at a greater risk of heart disease and early death than people with an intake of 4–5 grams.
How much salt is too little?
However, most Americans eat too much of it—and they may not even know it. Americans eat on average about 3,400 mg of sodium per day. However, the Dietary Guidelines for Americans recommends adults limit sodium intake to less than 2,300 mg per day—that’s equal to about 1 teaspoon of table salt!
