How Much Daily Salt Intake Is Safe?
Salt is essential for various bodily functions, including muscle contraction, nerve transmission, and fluid balance. However, consuming too much salt can have detrimental health effects. So, how much salt per day is safe?
Recommended Daily Salt Intake
According to a 2023 report by the World Health Organization (WHO), excessive salt intake is a major contributor to high blood pressure and increases the risk of heart disease and stroke. WHO estimates that reducing salt intake to recommended levels could prevent approximately 2.5 million deaths each year.
Health organizations around the world provide guidelines for safe salt consumption:
- World Health Organization (WHO): Less than 5 grams (about 1 teaspoon) per day.
- American Heart Association (AHA): Ideal limit of 1.5 grams per day for most adults; not exceeding 2.3 grams (about 1 teaspoon).
- Dietary Guidelines for Americans (DGA): Less than 2.3 grams per day for adults.

Excessive salt intake can lead to:
- High Blood Pressure: Salt increases blood pressure, a major risk factor for heart disease and stroke.
