How Much Salt Per Day Is Safe? WHO and AHA Guidelines Explained
Health organizations worldwide emphasize the importance of limiting salt intake to reduce the risk of cardiovascular disease. The World Health Organization (WHO) advises a daily salt consumption of less than 5 grams (approximately 2,000 mg of sodium). The American Heart Association (AHA) recommends an even stricter limit of 1,500 mg of sodium (3.75 grams of salt) per day, with a maximum cap of 2,300 mg (5.75 grams of salt). In the UK, the National Health Service (NHS) sets the upper limit at 6 grams of salt (2,400 mg of sodium) per day, while the Institute of Medicine (IOM) aligns with the AHA’s lower recommendation of 1,500 mg of sodium for most adults.
Health Implications of Excessive Salt Consumption
Excessive salt intake is closely linked to elevated blood pressure, a leading cause of heart disease, stroke, and kidney failure. Global health data attributes nearly 1.89 million diet-related deaths annually to high sodium intake. While the body requires only 1–2 grams of salt daily for essential functions, the global average intake is significantly higher, ranging from 10–12 grams per day. In the United States, sodium consumption averages 3,400 mg per day (approximately 8.5 grams of salt), far exceeding recommended limits.
Considerations for Different Populations
Salt intake recommendations vary by age and activity level. Children require lower amounts, with guidelines suggesting less than 2 grams per day for ages 1–3 and under 3 grams for ages 4–6. Athletes and individuals engaged in intense physical activity may need slightly higher sodium intake to compensate for losses through perspiration.
Strategies to Reduce Sodium Intake
To lower salt consumption, health experts recommend minimizing processed and packaged foods, which contribute up to 75% of dietary sodium. Choosing fresh fruits, vegetables, and whole foods can significantly reduce sodium intake. Additionally, using herbs and spices as alternatives to salt can enhance flavor without increasing health risks.
