A diet rich in protein and low in sodium offers significant benefits for heart health, blood pressure management, and kidney function. Most of the sodium we consume comes from processed and packaged foods, not the salt shaker. By focusing on fresh, whole foods, you can take control of your sodium intake while ensuring your body gets the protein it needs to build and repair tissues, produce enzymes and hormones, and support overall bodily functions.
Animal-Based Low-Sodium, High-Protein Foods
For those who include meat, fish, and dairy in their diet, several excellent options provide a powerful protein punch with minimal sodium. The key is to choose fresh, unprocessed versions and avoid items that are cured, smoked, or pre-marinated.
Lean Meats and Poultry
Fresh, unseasoned cuts are the best choice. Look for labels indicating no added salt or saline solution.
- Chicken and Turkey Breast (skinless): Excellent lean protein sources. A 4-ounce chicken breast provides around 26 grams of protein with only about 75 mg of sodium.
- Lean Cuts of Beef and Pork: Opt for cuts like sirloin, loin, or ground beef that is at least 90% lean.
Fish and Seafood
Fish is a heart-healthy protein source, often rich in omega-3 fatty acids, provided it isn't canned with salt.
- Fresh Salmon, Cod, Halibut, and Tilapia: Naturally low in sodium and high in protein.
- Canned Tuna or Salmon (No Salt Added): Canned fish is convenient but must be selected carefully. Choose options with "no salt added" on the label.
- Shrimp: Fresh or frozen shrimp is a good option, but check labels, as some are treated with a saline solution.
Eggs and Dairy
These are versatile and convenient sources of high-quality protein.
- Eggs: One large egg contains about 62 mg of sodium, making them a naturally low-sodium protein source. The sodium content only increases with added salt or high-sodium cheeses.
- Plain Greek Yogurt (Low-Fat): A 7-ounce serving provides nearly 20 grams of protein and is low in sodium, especially compared to flavored varieties.
- Cottage Cheese (No Salt Added): Traditional cottage cheese is high in sodium, but no-salt-added versions offer a great protein source with minimal sodium.
- Low-Sodium Cheeses: Cheeses vary widely in sodium content. Some varieties, like fresh mozzarella, tend to be lower, but always check the nutrition label.
Plant-Based Low-Sodium, High-Protein Foods
For vegetarians, vegans, or anyone looking to diversify their protein sources, plant-based options are abundant.
Legumes
Lentils and beans are versatile, fiber-rich, and excellent protein sources.
- Lentils: One cup of cooked lentils contains nearly 18 grams of protein and is very low in sodium.
- Dried Beans (Black, Kidney, Chickpeas): Cooking dried beans from scratch ensures no added salt. If using canned beans, opt for "low sodium" or "no salt added" versions and rinse them thoroughly.
- Edamame: Unsalted edamame is a fantastic snack. One cup provides over 18 grams of protein with just 7.8 mg of sodium.
Soy Products
Soy is a complete protein, meaning it contains all essential amino acids.
- Tofu and Tempeh: These fermented soy products are naturally low in sodium when unseasoned. Tempeh is generally higher in protein than tofu.
- Roasted Soybeans (Unsalted): A convenient and crunchy snack option.
Nuts and Seeds
These are great for snacking, adding to meals, or making spreads, as long as they are unsalted.
- Unsalted Nuts (Almonds, Peanuts, Pistachios): Unsalted varieties are high in protein and healthy fats. One ounce of unsalted almonds contains over 7.5 grams of protein.
- Seeds (Pumpkin, Hemp, Chia): A handful of unsalted pumpkin seeds provides a good amount of plant-based protein.
- Unsalted Nut Butters: Choose natural, no-salt-added peanut or almond butter.

Practical Tips for Reducing Sodium and Increasing Protein
Making the switch to a low-sodium, high-protein diet involves mindful choices both at the grocery store and in the kitchen. Focusing on whole, unprocessed foods is the most effective approach.
- Read Food Labels: Always check the "Nutrition Facts" panel for sodium content. The Dietary Guidelines for Americans recommend consuming less than 2,300 mg of sodium per day, with an ideal limit of 1,500 mg for certain individuals. Look for labels like "low sodium" (140 mg or less per serving) or "no salt added".
- Use Herbs and Spices: Instead of salt, add flavor with a variety of fresh or dried herbs and spices. Lemon juice, garlic, onion powder, and vinegar are also great alternatives.
- Cook at Home More Often: Restaurant and pre-packaged meals are often loaded with sodium. Cooking from scratch gives you complete control over your ingredients and seasoning.
- Rinse Canned Foods: If you can't find low-sodium canned items, rinsing and draining standard canned beans or vegetables can help reduce their sodium content by up to 40%.
- Be Mindful of Condiments: Many sauces, dressings, and condiments like soy sauce and ketchup are very high in sodium. Choose low-sodium versions or make your own from scratch.
By following these strategies, you can easily find delicious, satisfying, and heart-healthy options to build a diet that is both low in sodium and high in protein. Focusing on fresh, whole foods and flavor-enhancing seasonings ensures you don't have to sacrifice taste for nutrition.
