Lemons are great for replacing salt since they give the same zip and depth of flavor to food. You can grate the zest and include it in baked foods or squeeze the lemon and add a squirt to your food. Lemon works well in:  Salad dressings Pastas Poultry or seafood dishes Breadcrumbs Try to keep several types of fresh herbs on hand so you're more likely to cook with them. For even easier use, consider mincing (chopping them finely) and storing them in the fridge so you can quickly season or garnish your food. Try these fresh herbs that pair well with a variety of foods:  Basil Dill: Parsley Rosemary Thyme Chives Cooking with red or white wine is a great way to concentrate flavor in your food. Add about 1/2 cup of red or white wine to your dish and let it cook down so the wine reduces. Avoid using cooking wine or sherry which usually have salt added and are high in sodium. For example, add red wine to a pasta sauce and let it simmer for an hour to amplify the flavor. Or you can add a splash of white wine to a seafood pasta sauce and let it cook down. If you're cooking something that calls for a lot of water, you can usually replace it with a chicken, vegetable or beef stock. Ensure that the stock is salt-free (which is easy to do if you're making it at home). The stock will be more flavorful than the water and you won't even need to add salt. For example, if you're making a vegetable soup, replace the water with a stock for additional flavor. Mix up a quick salt-free marinade for meat or vegetables and heat up your grill. Grilling your food will give it a great smoky flavor and you won't even need to use salt. Try adding hickory or mesquite chips to the grill or grilling your food on a cedar wood plank for extra flavor. Try using a citrus-based marinade for even more seasoning. For example, marinate chicken in a lime vinaigrette and grill it for a bit of a smoky taste. There are a variety of vinegars you can use to replace salt. Try a splash of red wine vinegar, white wine vinegar, balsamic vinegar, or apple cider vinegar to give additional flavor to your food. Studies have shown that vinegar can enhance the salty flavor of foods. You can use vinegar in:  Stews Salads Marinades Braised vegetables

Summary:
Use a squirt of lemon. Cook with fresh herbs. Season the food with a little wine. Use chicken, vegetable or beef stock. Grill your food. Add a little vinegar.
