Low-Sodium Diet: How to Cut Salt and Boost Your Health
Swap processed options for fresh herbs and spices to enjoy vibrant meals with less salt.
Understanding Sodium: Why Cutting Back Matters
Most Americans consume much more sodium than recommended. While sodium is an essential mineral that helps regulate fluid balance, nerve function, and muscle contraction, excessive salt intake is a leading contributor to high blood pressure and heart disease. Current Dietary Guidelines for Americans recommend adults limit sodium intake to less than 2,300 mg per day, which is roughly one teaspoon of salt. However, the average American consumes well above this amount, often unknowingly.
Where Does Sodium Hide?
More than 70% of the sodium we eat comes from processed, packaged, and restaurant foods, not the salt shaker. Even foods that don’t taste salty—like bread, cereal, deli meats, and sauces—can contribute significant sodium to your diet.
- Packaged meals and frozen dinners
- Breads, bagels, tortillas
- Deli meats and cured meats
- Snack foods like chips and crackers
- Condiments such as soy sauce, salad dressings, ketchup
The Health Risks of Excess Sodium
Overconsumption of sodium is linked to a number of health risks, including:
- High blood pressure (hypertension)
- Heart disease and stroke
- Kidney disease
- Fluid retention and bloating
- Potential increased risk of osteoporosis and stomach cancer
High sodium intake causes the body to hold on to extra water, raising blood pressure and straining the heart, blood vessels, and kidneys. Over time, these effects increase the risk of heart attack, stroke, and kidney damage.
How Much Sodium Is Too Much?
| Group | Recommended Maximum Sodium (mg/day) |
|---|---|
| Healthy Adults | 2,300 |
| Adults Over 50 | 1,500 |
| People with Hypertension, African Americans, Anyone Over 50* | 1,500 |
*Those at risk for or diagnosed with hypertension, heart disease, or kidney issues should discuss sodium limits with their healthcare provider.
10 Practical Strategies to Lower Sodium Intake
Cutting back on sodium doesn’t mean sacrificing flavor or enjoyment. Here are proven strategies:
- Read Nutrition Labels: Choose foods with less than 100% of the daily value (2,300 mg) of sodium per serving.
- Prepare Your Own Meals: Cook from scratch when possible; limit packaged sauces, mixes, instant foods, and ready-made meals.
- Use Herbs, Spices, and No-Salt Seasoning: Enhance flavor naturally instead of relying on salt.
- Favor Fresh Ingredients: Fresh meat, poultry, and seafood generally contain less sodium than processed varieties. Always check for added saline or brine.
- Choose Fresh or Frozen Vegetables: Select options without added sauce or salt; rinse canned veggies to remove excess sodium.
- “Unsalt” Snacks: Opt for low-sodium or unsalted versions of nuts, seeds, chips, and pretzels; substitute veggies like carrots or celery.
- Be Mindful of Condiments: Many condiments pack hidden sodium. Use reduced-sodium versions, oil and vinegar, and limit salad dressings.
- Watch Your Portions: Smaller servings mean less sodium.
- Make Better Choices Eating Out: Request no added salt, put dressings and sauces “on the side,” and make informed menu choices.
- Gradually Adjust Your Palate: Your taste for salt will decrease over time as you reduce your intake.

- Choose grilled, baked, or steamed dishes over fried foods
- Request nutrition information to compare sodium content
- Split meals or order smaller portions to limit intake
Is a Low-Sodium Diet Always Better?
While most Americans eat too much sodium, recent research suggests a very low sodium intake (<2,300mg/day) can trigger the body’s sodium-conserving hormones, which may negatively impact health for some. A large study found that people consuming between 2,645 and 4,945 mg per day had better mortality rates and fewer cardiovascular events compared to those on aggressively low-salt regimens. People with certain medical conditions (e.g. hypertension) should still aim to limit sodium, but not everyone benefits from extremely low intake. Consult your healthcare provider to personalize your sodium targets.
Frequently Asked Questions (FAQs)
Q: What are the main benefits of cutting back on sodium?
A: Lower sodium intake helps reduce blood pressure, improves heart and kidney health, decreases fluid retention, and lowers risk of stroke and other complications.
Q: Do I need to avoid salt completely?
A: No. Sodium is essential for bodily functions, but moderation is key. Most people benefit from meeting, not exceeding, the daily limits.
Q: How can I tell if a food is high in sodium?
A: Check the Nutrition Facts label. Foods with more than 20% Daily Value (DV) per serving are considered high in sodium. Compare brands and choose those with “reduced sodium” or “no salt added.”
Q: Are “sea salt,” “kosher salt,” and “Himalayan salt” healthier choices?
A: All salts, including specialty varieties, contain roughly the same amount of sodium per gram. The health impacts depend on total sodium consumed, not the type of salt.
Q: Can fruits and vegetables be high in sodium?
A: Fresh fruits and vegetables are naturally low in sodium. Canned or pickled options may be high, so always check labels and rinse canned goods to remove some sodium.
Q: What are some tasty swaps for salty foods?
- Choose unsalted nuts over salted varieties
- Make homemade soup using low-sodium broth
- Try homemade salad dressings with olive oil, vinegar, and herbs
- Bake or grill proteins instead of using pre-seasoned or breaded meats
