What is Considered Low Salt Content in Food?

3 min read

According to the U.S. Food and Drug Administration (FDA), a food item labeled “low sodium” must contain 140 mg of sodium or less per serving. Understanding these regulated terms and how to read nutrition labels is essential for anyone aiming to monitor and reduce their salt intake.

Quick Summary

Official food label definitions, including 'low sodium' and 'sodium-free,' help identify products with lower salt content. The 5% Daily Value rule is a useful tool for comparison, and limiting processed foods is key to managing overall sodium intake effectively.

Key Points

  • Low Sodium Definition: A product is legally considered 'low sodium' if it contains 140 mg of sodium or less per serving.

  • Reading Labels: Check the % Daily Value (%DV) on the nutrition label; 5% DV or less per serving is considered low sodium.

  • Limit Processed Foods: Most sodium in the average diet comes from processed, packaged, and restaurant foods, not from home cooking.

  • Flavor Alternatives: Enhance flavor using herbs, spices, lemon juice, or vinegar instead of salt.

  • Health Benefits: Reducing salt intake can help lower blood pressure and decrease the risk of heart disease and stroke.

  • Palate Adjustment: The taste buds can adapt to a lower-salt diet over time, making naturally less salty foods more appealing.

Decoding Food Labels for Low Salt Content

To accurately determine a product's sodium level, you must understand the FDA's definitions for nutrient content claims. These regulated terms are your best tool for identifying low-salt options while shopping.

  • Sodium-Free or Salt-Free: Less than 5 milligrams (mg) of sodium per serving.
  • Very Low Sodium: 35 mg of sodium or less per serving.
  • Low Sodium: 140 mg of sodium or less per serving.
  • Reduced or Less Sodium: At least 25% less sodium than the regular version, but the absolute amount may still be high.
  • Light in Sodium or Lightly Salted: At least 50% less sodium than the regular version.
  • No Salt Added or Unsalted: No salt added during processing, but sodium may still be present naturally. Always check the nutrition facts.

The Importance of the % Daily Value

The % Daily Value (%DV) on the Nutrition Facts label is a key indicator. The FDA considers 5% DV or less of sodium per serving to be low, while 20% DV or more is considered high. This helps quickly compare products.

Understanding Your Daily Sodium Goal

Most Americans consume around 3,400 mg of sodium daily, exceeding the recommended less than 2,300 mg per day (Dietary Guidelines) or ideally under 1,500 mg (American Heart Association). Most sodium comes from processed and commercially prepared foods.

The Hidden Sources of Salt

Processed foods use salt as a preservative, for moisture retention, and to mask flavors, making it common in many items. This hidden salt contributes significantly to excess sodium intake. Cooking from scratch with fresh ingredients allows for better control over sodium.

A Guide to High and Low-Sodium Foods

Choosing fresh, whole foods and limiting processed items is the most effective way to manage sodium intake.

High Sodium vs. Low Sodium: A Comparison Table

Food Category High-Sodium Example Low-Sodium Example
Protein Cured meats, deli meats, salted nuts Fresh chicken, lean beef, unsalted nuts, dried beans
Dairy Processed cheese, cottage cheese Plain yogurt, low-sodium cheese, milk
Vegetables Canned vegetables (regular), pickles Fresh or frozen vegetables, low-sodium canned vegetables, drained & rinsed canned beans
Snacks Chips, pretzels, salted crackers Unsalted nuts, seeds, fresh fruit, unsalted popcorn
Sauces/Condiments Soy sauce, ketchup, bouillon cubes Low-sodium soy sauce, vinegar, herbs, spices

Practical Strategies for a Low-Salt Lifestyle

Using herbs (basil, parsley), spices (garlic powder, onion powder), lemon, lime, or vinegar enhances flavor without salt. Experimenting with spice blends can add variety.

Navigating Dining Out

Restaurant meals are often high in sodium. Ask for no added salt and sauces/dressings on the side. Choose baked, grilled, or steamed dishes.

The Health Benefits of a Low-Sodium Diet

Reducing salt intake offers significant health benefits, primarily lowering blood pressure, a risk factor for heart attack and stroke. Lowering sodium reduces blood pressure and cardiovascular disease risk. It also supports kidney function and bone density. Over time, your palate will adapt to prefer less salt.

Conclusion Understanding what is considered low salt content in food is key to a healthier diet. Utilize FDA definitions like 'low sodium' (140mg or less per serving) and the 5% Daily Value rule on labels. Prioritize fresh, whole foods over processed ones, which are major sodium sources. Flavor food with herbs, spices, and citrus instead of excessive salt. This approach improves heart health and overall well-being. For more resources, visit the FDA website.

Frequently Asked Questions

The Dietary Guidelines for Americans recommend that adults consume less than 2,300 mg of sodium per day, while the American Heart Association suggests aiming for an ideal limit of no more than 1,500 mg per day.

No, a 'no salt added' claim means no salt was added during processing, but the food may still naturally contain sodium. It is important to check the Nutrition Facts label for the actual sodium content.

You can significantly reduce the sodium content of canned goods like beans and vegetables by draining and rinsing them thoroughly with water before use. This can wash away a substantial amount of the added salt.

Common high-sodium foods include processed and cured meats, fast food, frozen meals, canned soups, many cheeses, and condiments like soy sauce. They rely on salt for preservation and flavor enhancement.

Yes, they will. Most people find that after consistently reducing their salt intake, their palate becomes more sensitive to the natural flavors of food. After a few weeks, heavily salted foods often taste overwhelmingly salty.

No, per teaspoon, sea salt and kosher salt contain roughly the same amount of sodium as table salt. They are not healthier or lower-sodium alternatives, despite having a different texture or crystal size.

Excellent alternatives to salt include using herbs (fresh or dried), spices, garlic powder, onion powder, citrus juices (lemon, lime), and vinegars to add flavor and complexity to your dishes.
