Saltreduction

Salt reduction refers to efforts aimed at decreasing sodium intake at the population level by lowering the salt content in foods, changing consumer behavior, and improving labeling and education. It encompasses strategies that involve the food industry reformulating processed foods to contain less sodium, as well as initiatives to encourage individuals to use less salt in cooking and at the table.

Rationale for salt reduction rests on the link between high sodium intake and elevated blood pressure, which is a major risk factor for cardiovascular disease. Public health authorities in many countries promote sodium targets and daily intake limits; typical recommendations advise fewer than 2,000 to 2,300 milligrams of sodium per day, though targets vary by region. In most populations, actual intake exceeds these guidelines.

Strategies include reformulation of processed foods to lower sodium content, often through gradual, incremental reductions to maintain palatability and consumer acceptance. Public awareness campaigns, front-of-pack labeling, and clear nutrition information help consumers make lower-sodium choices. Government procurement policies, nutrition standards in schools and public institutions, and monitoring and evaluation systems support ongoing progress. Industry partnerships, regional targets for different food categories, and national benchmarks are common components.

Substitutes such as potassium chloride are used in some salt-reduced products, but they require caution for individuals with kidney problems or on certain medications. Programs may also consider maintaining iodine intake if iodized salt use declines.

Evidence from several countries indicates that sustained salt reduction efforts can lower population sodium intake and, in some cases, blood pressure, though results vary with program design and implementation.
