Sodium is one of the main elements in NaCl or table salt. It is added to many foods to enhance the flavor. Too much sodium is linked to high blood pressure.
Eating a low-salt diet is an important way to take care of your heart. Most people eat about 3,400 mg of sodium a day. This is about twice as much as the American Heart Association recommends. Most healthy people should have no more than 2,300 mg of salt a day. People over 51, and those who have high blood pressure, may need to limit sodium to 1,500 mg a day or less.
To get down to a healthy level, learn how to trim the excess salt from your diet.
Processed foods make dinner prep easy. But they account for 75% of the sodium in the American diet. This includes:
- Prepared mixes
- Packaged rice dishes
- Canned foods
A healthy level of sodium is 140 mg or less per serving. If you use prepared foods, limit sodium by:
- Looking closely at a foods nutrition label for the milligrams of salt per serving. Be sure to note how many servings are in the package.
- Buying products labeled "low-salt," or "no salt added."
- Checking the nutrition labels of cereals, bread, and prepared mixes.
- Rinsing canned beans to wash off some of the sodium.
- Using frozen or fresh vegetables in place of canned vegetables.
- Avoiding cured meats like ham and bacon, pickles, olives, and other foods prepared in salt.
- Choosing unsalted brands of nuts and trail mix.
Also, use small amounts of condiments like ketchup, mustard, and soy sauce. Even the low-salt versions are often high in sodium.
Bring on the Fresh Produce
Fruits and vegetables are a great source of flavor and nutrition.
- Plant-based foods -- carrots, spinach, apples, and peaches -- are naturally low in sodium.
- Sun-dried tomatoes, dried mushrooms, cranberries, cherries, and other dried fruits are bursting with flavor. Use them in salads and other dishes to add zest.
Try Salt-free Cooking
Explore cooking with salt substitutes.
- Add a splash of lemon and other citrus fruits, or wine, to soups and other dishes. Or, use them as a marinade for chicken and other meats.
- Avoid onion or garlic salt. Instead, use fresh garlic and onion, or onion and garlic powder.
- Try different types of pepper, including black, white, green, and red.
- Experiment with vinegars (white and red wine, rice wine, balsamic, and others). For the most flavor, add it at the end of cooking time.
- Toasted sesame oil adds a savory flavor without added salt.
Read the labels on spice mixes. Some have added salt.
To add a little heat and spice, try:
- Dry mustard
- Fresh chopped hot peppers
- A sprinkle of paprika, cayenne pepper, or dried hot red pepper
Help Yourself to Herbs and Spices.
Herbs and spices provide a mix of flavors. If you are not sure what spices to use, do a taste test. Mix a small pinch of a spice or spice mix into a lump of low-fat cream cheese. Let it sit for an hour or more, then try it and see if you like it.
Try these flavors to liven up your meals without salt.
Herbs and spices on vegetables:
- Carrots -- Cinnamon, cloves, dill, ginger, marjoram, nutmeg, rosemary, sage
- Corn -- Cumin, curry powder, paprika, parsley
