What Is Sodium and Why Does It Matter for Your Health?
Sodium is an essential mineral that helps regulate fluid balance, nerve signals, and muscle function. However, most people consume far too much—averaging over 3,400 mg daily—compared to the American Heart Association’s ideal limit of 1,500 mg (maximum 2,300 mg). Excess sodium forces your body to retain water, raising blood pressure and increasing risks of hypertension, heart disease, stroke, kidney damage, and even osteoporosis.
What Are the Real Risks of Too Much Sodium?
- High blood pressure (hypertension)
- Heart attack and heart failure
- Stroke and cardiovascular events
- Chronic kidney disease
- Bone calcium loss leading to osteoporosis
Lowering sodium is one of the fastest ways to drop blood pressure and protect long-term health.
What Are the Proven Benefits of a Low-Sodium Diet?
- Better blood pressure control (often within weeks)
- Reduced strain on the heart and lower heart disease risk
- Healthier kidneys and slower progression of kidney disease
- Easier weight management (many high-sodium foods are also high-calorie)
- Lower risk of stroke
How Much Sodium Should You Actually Eat Daily?
| Group | Recommended Limit |
|---|---|
| General healthy adults | ≤ 2,300 mg/day |
| Ideal target (most adults) | ≤ 1,500 mg/day |
| High blood pressure, heart/kidney issues, age 51+ | 1,500 mg/day max |
How to Read Labels and Spot Hidden Sodium?
Look at “mg of sodium per serving.”
- Sodium-free: < 5 mg
- Very low sodium: < 35 mg
- Low sodium: < 140 mg Always check serving size—doubling the portion doubles the sodium.
Which High-Sodium Foods Should You Limit or Avoid?
- Processed meats (bacon, sausage, deli meats)
- Canned soups and vegetables (unless no-salt-added)
- Frozen meals and pizza
- Salty snacks (chips, pretzels)
- Cheese and flavored yogurt
- Condiments (soy sauce, ketchup, salad dressing)
- Restaurant and takeout meals

Expert Insight
Cardiologist Dr. Nancy McLean: “Cutting sodium is often more effective than adding another blood-pressure pill.” Registered Dietitian Daniel Rogers: “Food can still explode with flavor—garlic, lemon, smoked paprika, and fresh herbs prove salt is optional.”
Can a Low-Sodium Diet Also Help Manage Diabetes? – TapHealth
Yes! People with diabetes or prediabetes benefit doubly from reducing sodium because high blood pressure is a common complication. A low-sodium approach supports both blood sugar stability (by encouraging whole, minimally processed foods) and cardiovascular protection—exactly what TapHealth recommends for long-term diabetes management and heart health.
