A low-sodium diet
limits foods that are high in sodium (salt). You will need to follow a low-sodium diet if you have high blood pressure, kidney disease, or heart failure. You may also need to follow this diet if you have a condition that is causing your body to retain (hold) extra fluid. You may need to limit the amount of sodium you eat to 1,500 mg. Ask your healthcare provider how much sodium you can have each day.
How to use food labels to choose foods that are low in sodium:
Read food labels to find the amount of sodium they contain. The amount of sodium is listed in milligrams (mg). The % Daily Value (DV) column tells you how much of your daily needs are met by 1 serving of the food for each nutrient listed. Choose foods that have less than 5% of the DV of sodium. These foods are considered low in sodium. Foods that have 20% or more of the DV of sodium are considered high in sodium. Some food labels may also list any of the following terms that tell you about the sodium content in the food:
- Sodium-free: Less than 5 mg in each serving
- Very low sodium: 35 mg of sodium or less in each serving
- Low sodium: 140 mg of sodium or less in each serving
- Reduced sodium: At least 25% less sodium in each serving than the regular type
- Light in sodium: 50% less sodium in each serving
- Unsalted or no added salt: No extra salt is added during processing (the food may still contain sodium)
Foods to avoid:
Salty foods are high in sodium. You should avoid the following:
- Processed foods:
- Mixes for cornbread, biscuits, cake, and pudding
- Instant foods, such as potatoes, cereals, noodles, and rice
- Packaged foods, such as bread stuffing, rice and pasta mixes, snack dip mixes, and macaroni and cheese

Read the food label to find the exact amount of sodium in each serving.

Ways to decrease sodium:
- Add spices and herbs to foods instead of salt during cooking. Use salt-free seasonings to add flavor to foods. Examples include onion powder, garlic powder, basil, curry powder, paprika, and parsley. Try lemon or lime juice or vinegar to give foods a tart flavor. Use hot peppers, pepper, or cayenne pepper to add a spicy flavor to foods.
- Do not keep a salt shaker at your kitchen table. This may help keep you from adding salt to food at the table. It may take time to get used to enjoying the natural flavor of food instead of adding salt. Talk to your healthcare provider before you use salt substitutes. Some salt substitutes have a high amount of potassium and need to be avoided if you have kidney disease.
- Choose low-sodium foods at restaurants. Meals from restaurants are often high in sodium. Some restaurants have nutrition information on the menu that tells you the amount of sodium in their foods. If possible, ask for your food to be prepared with less, or no salt.
- Shop for unsalted or low-sodium foods and snacks at the grocery store. Examples include unsalted or low-sodium broths, soups, and canned vegetables. Choose fresh or frozen vegetables instead. Choose unsalted nuts or seeds or fresh fruits or vegetables as snacks. Read food labels and choose salt-free, very low-sodium, or low-sodium foods.
