Sodium Recommendations
Sodium is an essential mineral for fluid balance, nerve function, and muscle contraction. However, most people consume far more than needed:
- General adults: Less than 2,300 mg/day (about 1 teaspoon of salt)
- Adults 51+: Less than 1,500 mg/day
- People with hypertension, heart disease, or kidney disease: Less than 1,500 mg/day
The average American consumes about 3,400 mg/day — nearly 50% over the general limit.
How Sodium Affects Blood Pressure
High sodium intake causes water retention, which increases blood volume and raises blood pressure. Reducing sodium by 1,000 mg/day can lower systolic blood pressure by 2–6 mmHg on average.
The DASH diet (Dietary Approaches to Stop Hypertension) limits sodium to 2,300 mg/day (or 1,500 mg for those with hypertension) and emphasizes fruits, vegetables, whole grains, and low-fat dairy. Studies show it can reduce systolic BP by 8–14 mmHg.
Hidden Sources of Sodium
Most sodium (70-75%) comes from processed and restaurant foods, not the salt shaker:
- Bread and rolls (~230mg per slice)
- Pizza, sandwiches, cold cuts
- Canned soups (~800-900mg per cup)
- Soy sauce (1 tablespoon = ~900mg)
- Processed meats (bacon, sausage, deli meats)
- Fast food: a typical burger meal can contain 1,500–2,500mg
Cooking at home with fresh ingredients dramatically reduces sodium intake.

Frequently Asked Questions
Does everyone need to restrict sodium?
Most health guidelines recommend limiting sodium for all adults, as high intake is linked to hypertension and cardiovascular disease even in those without symptoms. People with hypertension, kidney disease, or heart failure need stricter limits. Athletes and people who sweat heavily may need more sodium.
What's the difference between sodium and salt?
Table salt (sodium chloride) is about 40% sodium by weight. So 1 gram of salt contains 400mg of sodium. When tracking sodium from food labels, use the mg sodium figure directly. To convert salt to sodium: multiply salt grams by 0.4.
Can I replace regular salt with sea salt or Himalayan salt?
No — from a sodium perspective, sea salt, Himalayan salt, and regular table salt are nearly identical. They all contain about 2,300mg of sodium per teaspoon. Specialty salts may have trace minerals but the sodium content and health effects are the same.
