Fig. 4: Projections for reducing sodium consumption when discretionary intake is high.

The estimate assumes 3100 mg sodium/d is added in food preparation and seasoning at home. Discretionary would fall 5% annually by replacing 20% of added salt with 75% NaCl: 25% KCl each year for 8 years. If non-discretionary sodium also declines 10% annually, then total sodium intake would fall from 4300 to 2800 mg daily. Potassium intake would rise ~1800 mg/d.
