Based on the American Heart Association recommendations for sodium intake, the ideal limit for most adults translates to no more than 3,750 mg of salt per day, while the maximum recommended limit is no more than 5,750 mg of salt per day.
When discussing daily intake recommendations related to salt, health organizations often refer to sodium rather than salt itself. This is because sodium is the component in salt (sodium chloride) that primarily affects blood pressure and heart health.
Understanding Salt and Sodium
- Salt is a compound made of sodium and chloride (NaCl).
- Approximately 40% of salt is sodium.
- Therefore, 1 gram of salt contains about 400 milligrams (mg) of sodium.
- Conversely, to find the salt equivalent of a given amount of sodium, you can multiply the sodium amount by 2.5.
American Heart Association Sodium Recommendations
The American Heart Association (AHA) provides specific guidelines for sodium intake to promote heart health. According to the AHA:
- Most adults should aim for an ideal limit of no more than 1,500 mg of sodium per day.
- They recommend no more than 2,300 mg of sodium per day as an upper limit.
- Even reducing intake by just 1,000 mg of sodium per day can significantly improve blood pressure and heart health for the average American who consumes excess sodium.

Translating Sodium Limits to Salt Limits
Using the conversion (Sodium mg * 2.5 = Salt mg), we can translate the AHA's sodium recommendations into approximate salt limits:
| Sodium Limit (AHA Recommendation) | Equivalent Salt Limit (Approximate) |
|---|---|
| Ideal Limit: 1,500 mg/day | 3,750 mg/day (about ¾ teaspoon) |
| Upper Limit: 2,300 mg/day | 5,750 mg/day (about 1 teaspoon) |
| Reduction for benefit: 1,000 mg/day | 2,500 mg/day |
Note: 1 teaspoon of salt is roughly 6,000 mg.
Why Reduce Salt (Sodium) Intake?
High sodium intake is linked to high blood pressure, a major risk factor for heart disease and stroke. Reducing the amount of sodium (and thus salt) in your diet can help lower blood pressure and improve overall cardiovascular health.
Practical Tips for Reducing Salt/Sodium Intake
- Read Food Labels: Pay attention to the sodium content on packaged foods.
- Choose Fresh Foods: Unprocessed foods like fruits, vegetables, lean meats, and whole grains are naturally lower in sodium.
- Limit Processed Foods: Many processed and packaged foods, including snacks, prepared meals, and sauces, are high in hidden sodium.
- Cook at Home: Preparing meals from scratch allows you to control the amount of salt added.
- Use Herbs and Spices: Season food with herbs, spices, lemon juice, or vinegar instead of relying solely on salt.
- Rinse Canned Goods: Rinsing canned vegetables or beans can remove some of the sodium.
By being mindful of sodium content and making conscious food choices, you can work towards staying within the recommended limits for better heart health.
