About AHA Sodium Guidelines

The American Heart Association recommends limiting sodium to 2300mg/day, with an ideal target of 1500mg/day for best cardiovascular health. Most Americans consume over 3400mg daily, primarily from processed foods.

Sodium and Cardiovascular Health

Sodium is an essential mineral that helps regulate fluid balance, nerve function, and muscle contractions. However, most people consume far more than needed — the average American takes in about 3400mg per day, well above the 2300mg limit recommended by the AHA and Dietary Guidelines for Americans.

Why Sodium Limits Matter

Excess sodium causes the kidneys to retain water, increasing blood volume and the pressure on artery walls. Over time, chronically elevated blood pressure damages arteries and significantly increases the risk of heart attack, stroke, kidney disease, and heart failure. Reducing sodium intake is one of the most impactful dietary interventions for cardiovascular health.

Understanding the Two Targets

2300mg — General Limit

The upper limit for most adults, aligned with the Dietary Guidelines for Americans 2020-2025. A realistic near-term goal for most people reducing their sodium intake.

1500mg — Ideal Target

The AHA's ideal target for optimal cardiovascular health. Especially important for those with hypertension, diabetes, chronic kidney disease, or at elevated cardiovascular risk.

Where Sodium Comes From

Contrary to popular belief, only about 11% of dietary sodium comes from salt added at the table or during cooking. About 70-75% comes from processed, packaged, and restaurant foods — breads, cold cuts, pizza, soups, sandwiches, and fast food are among the largest contributors. Cooking at home with fresh ingredients is the single most effective way to reduce sodium intake.
