Interventions to Reduce Sodium Consumption Through a Reduction in Salt Usage in Cooking-A Systematic Review and Meta-analysis.

In 30 seconds

This systematic review and meta-analysis evaluated interventions aimed at reducing salt usage in cooking among adults. The analysis included 13 studies, revealing a significant trend towards reduced sodium intake, with a Hedges' g of -1.06 (95% CI, -1.68 to -0.44; P < .001) across 3185 participants. Educational initiatives were particularly effective in decreasing urinary sodium excretion.

Key findings

• Interventions showed a significant trend towards reducing sodium intake with Hedges' g of -1.06.
• Three studies reported significant reductions in urinary sodium excretion primarily through educational efforts.
• The review included 13 studies, comprising 5 intervention protocols and 8 randomized controlled trials.
• The findings support the World Health Organization's goal of a 30% reduction in salt intake by 2030.

Why it matters

Reducing sodium intake is crucial for preventing cardiovascular disease and other chronic illnesses. Effective interventions can help achieve public health goals and improve population health outcomes.
