Low-Sodium Diet Guide
Complete low-sodium diet guide for heart health, covering sodium recommendations, reading labels, low-sodium foods, cooking tips, and who should limit sodium.
What the Low-Sodium Diet Involves
A low-sodium diet restricts salt intake to support heart health, manage blood pressure, and reduce fluid retention. While sodium is an essential mineral needed for nerve function and fluid balance, most people consume far more than necessary, which can contribute to hypertension and cardiovascular disease.
The American Heart Association recommends limiting sodium to 2,300 milligrams per day, with an ideal target of 1,500 milligrams for most adults, especially those with high blood pressure. The average American consumes over 3,400 milligrams daily, with most coming from processed and restaurant foods rather than the salt shaker.
Reducing sodium requires attention to food labels, cooking methods, and food choices. While it may seem challenging at first, many people find that after several weeks of eating less salt, their taste preferences adjust and they begin to appreciate the natural flavors of foods.
Potential Benefits
Lower Blood Pressure
Reducing sodium intake can lower blood pressure, particularly in people who are salt-sensitive. Even modest reductions in sodium can produce meaningful blood pressure decreases.
Reduced Heart Disease Risk
High sodium intake is associated with increased risk of heart attack, stroke, and heart failure. Limiting sodium is a key component of heart-healthy eating.
Less Fluid Retention
Sodium causes the body to retain water. Reducing intake can help decrease bloating, swelling, and water weight.
Kidney Health
Lower sodium intake reduces the workload on kidneys and may help protect kidney function, especially important for those with kidney disease.
Improved Overall Diet Quality
Reducing processed foods to cut sodium often leads to higher intake of whole foods, fruits, vegetables, and home-cooked meals.
Note: Individual results may vary. Research findings represent population averages, and your experience may differ based on genetics, overall health, and adherence to the diet.

Who Should Consult a Doctor
Important Health Considerations
Consult your healthcare provider before starting a low-sodium diet if you take medications for blood pressure, heart disease, or kidney conditions, have been diagnosed with hyponatremia (low blood sodium), are an endurance athlete (sodium needs may be higher), have adrenal insufficiency, or experience symptoms like dizziness, fatigue, or muscle cramps. Some people may need to balance sodium restriction with adequate intake.
