Whether you go on a low sodium diet for medical reasons or because you’re tired of being bloated all the time, adapting a low sodium diet can be challenging. The good thing is there are many ways to make your dishes pop with flavor without adding unnecessary amounts of salt. If you are trying to maintain a low sodium lifestyle, cooking from home may be the best option so you can control just how much salt goes into your food. Here are some of the best ways to liven up your dish when you cook without sacrificing your health.
Herbs and Spices
The right herbs and spices can fill your dish with loads of flavor. There are many options to choose from when it comes to herbs and spices which can keep things on your plate interesting! Add fresh or dried herbs like basil, oregano, and parsley. Choose spices that pack a punch such as curry, paprika, and garlic powder. Make sure you check the label if you are buying pre-made spice combos as there can be added salt in them.
Nutritional Yeast
Most cheeses are high in sodium, but with nutritional yeast you don’t have to miss out on the amazing cheese flavor. Nutritional yeast, often used by vegans as a cheese substitute, has a deep cheesy flavor that can be used on any foods you desire. Sprinkle this flavoring over your favorite dishes and you’ll be presently surprised how well it can satisfy a cheese craving. From rice and veggies to popcorn and even salads – its uses go a long way!
Broth
Most store-bought broths are loaded with sodium, so make sure you purchase a low-sodium brand or make your own. You can make both vegetable and meat broth by boiling veggies or bones in a pot and adding spices and herbs – not salt – for more flavor. Using the broth as a “base” for other dishes will add flavor where least expected such as using the broth as the water substitute in boiling rice, or even potatoes, so no additional seasoning is needed.
Onions and Garlic
Aromatics play a huge role in adding flavors to many dishes. Roasted garlic and caramelized onions can make a dish turn from bland to sweet and savory fast. Chop them up and toss with olive oil in a pan, or bake in the oven with your choice of lean protein, potatoes, or veggies.

Citrus
Believe it or not, lemon is a great natural flavor to replace salt. Adding a few generous squirts of either lemon or lime to a plate will encourage other flavors to pop while also adding a refreshing, strong flavor all on their own. Try marinating your meals the night before in citrus to optimize flavor.
Marinate
There are many different flavors used in marinating to keep your plates ever-changing and satisfying – providing flavor without necessarily adding salt. If you choose to buy a marinade, always read labels to make sure they are low-sodium. Keep in mind you don’t have to buy pre-made marinades each time, you can get creative and use a tasty low-sodium salad dressing, or experiment with different kinds of vinegar at home. From sweet to spicy, marinating will bring some excitement out in many of your favorite dishes – you won’t even miss the salt!
