Sodium Content in Fresh Salmon Filet

Fresh salmon filet contains approximately 50-60 mg of sodium per 100g (3.5 oz) serving in its natural state. 1

Detailed Sodium Content Analysis

When examining the nutritional composition of fresh salmon, it's important to distinguish between naturally occurring sodium and sodium added during processing or preparation:

  • Natural sodium content: Fresh, unprocessed salmon filet contains relatively low levels of sodium naturally
  • Prepared salmon: The baked salmon recipe in the evidence shows that a 4-oz serving of prepared salmon (as part of a complete dish with bun and sauce) contains about 495 mg of sodium 1
  • Processing impact: When salmon undergoes processing like brining or smoking, sodium content increases significantly

Factors Affecting Sodium Content in Salmon

Several factors can influence the sodium content in salmon:

  • Preparation method: Fresh salmon without added salt has the lowest sodium content
  • Cooking additions: Salt, seasonings, and sauces added during cooking significantly increase sodium content
  • Processing: Commercial processing techniques like injection-salting can increase sodium content to 1.7%-6.5% (equivalent to 1700-6500 mg per 100g) 2

Contextualizing Sodium Content

For those monitoring sodium intake:

  • Daily recommendations: The American Heart Association recommends limiting sodium intake to ≤2300 mg/day, with an ideal target of 1500 mg/day for most adults 3
  • Low sodium definition: Foods containing less than 140 mg or 5% Daily Value of sodium are considered low in sodium 3
  • Salmon in diet planning: Fresh salmon fits well within low-sodium diet plans when prepared without added salt

Practical Implications

Fresh salmon is a heart-healthy protein choice that naturally contains:

  • Low sodium: Making it suitable for sodium-restricted diets
  • High omega-3 fatty acids: One fatty fish serving per week (4 oz) such as salmon provides the recommended daily intake of LC n-3 PUFAs (≈250 mg/d) 1

Preparation Tips to Maintain Low Sodium Content

  • Use herbs and spices instead of salt to flavor salmon
  • Avoid pre-packaged marinades and sauces which often contain high sodium
  • Read nutrition labels when purchasing pre-seasoned salmon products
  • Rinse canned salmon to reduce sodium content if using canned varieties

Fresh salmon's naturally low sodium content makes it an excellent choice for those monitoring their sodium intake while still obtaining beneficial nutrients like omega-3 fatty acids.
