If you have elevated blood pressure, you probably consume a low-sodium diet as part of your lifestyle.

Sodium gets a bad rap, but it’s not all bad. It’s an essential mineral for your body’s health. Commonly found in table salt, it flavors and preserves foods, makes brines.

Unfortunately, it’s easy to go overboard with your sodium intake. Too much sodium isn’t healthy, especially for your heart. This reason is why so many people are choosing a low-sodium diet. So, how does a low-sodium diet improve your heart health?

What is sodium?

Sodium is a necessary mineral for your body. It maintains the fluid balance in your cells and adds electrolytes to your body. It also supports the movement of your nerve impulses, aids your muscles to contract and relax, and aids your digestion, plus maintains your blood volume and blood pressure.

How much sodium do you need?

But eating enough sodium isn’t usually a problem, because today most Americans eat way too much sodium in their diet. Dietary guidelines suggest you should consume between 1500mg to  2,300 mg or one teaspoon of sodium per day, but the typical American eats at least 3,400mg or more of sodium.

High sodium and your health

Overeating sodium leads to high blood pressure, heart disease, or stroke. Consuming too much sodium can even affect your brain and cause calcium loss in your bones.

Choosing a low-sodium diet

Studies have found that adults who chose to reduce sodium levels in their diet had lower blood pressure, less risk of stroke or heart disease. Overall, a low sodium diet is a healthy choice.

Simple steps to lower sodium

Eating low sodium improves your health, but where do you begin?  Here are some simple steps you can take to start eating less sodium.

1 – Bye, bye salt shaker

Adding salt to your food isn’t necessary. Many foods already contain sodium, so you put your salt shaker away, and you’ll instantly lower your sodium intake.

2 – Eat more fresh foods

A straightforward way to reduce sodium in your diet is to stop eating processed foods and eat mostly fresh fruits, vegetables, and meats. Many of these contain natural sodium, so you’ll still get some sodium in your diet.

3 – Limit processed flavorings

Stay away from onion and garlic salts, soy sauce, teriyaki sauce, ketchup, pickles, olives, or barbeque sauce. Create your barbeque sauce, use fresh garlic and onion. Shop for low sodium soy sauce and ketchup. Substitute tamari sauce for soy sauce in your Asian cooking.

4 – Change up your recipes

When you’re cooking, cut the recipe’s recommended salt level in half. This way, you get the flavor, but less sodium.

5 – Rinsing canned foods

If you buy canned veggies, rinse them off before using them in your recipes. Rinsing removes as much as 40% of the sodium from the vegetables.

6 – Find a flavor-filled alternative

Lemon and lime juice or vinegar adds a zesty flavor that mimics salt. Use these in soups, marinades, stews, and sauces.

7 – Steer clear of convenience foods

Canned foods, gravy mixes, canned soup, boxed vegetables, rice mixes, puddings, and frozen meals are loaded with sodium.

8 – Read the labels on your groceries

Take notice of sodium levels in foods you’re buying. It’s shocking at first to see how much sodium is in prepackaged foods. Reading labels will help you find foods with less sodium. You can find alternative foods with less sodium but with the same big flavors.


High sodium foods to avoid

  • Premade pizza-the sauce, cheese, and pepperoni are packed with sodium
  • Soups-canned soups are full of sodium
  • Sandwiches-deli meats and cheese are prepared with sodium
  • Pre marinated meats-marinated meats are convenient, but they have lots of sodium
  • Bread, bagels, rolls, and tortillas

Low sodium alternatives

Another way to eat low sodium is to exchange high sodium foods for their lower-sodium alternatives. Here are easy to make sodium choices to incorporate into your everyday diet.

Choose low sodium bread, rolls, and tortillas. Bake your bread or rolls. Many easy recipes aren’t that hard, and don’t take too long to prepare.  Make your tortillas. It’s not as hard as you might think. Here is a simple homemade tortilla recipe.


Easy flour tortilla recipe


  • 2 ½ cups of a good brand of unbleached flour
  • One teaspoon baking powder (low sodium version, found at health food stores)
  • ½ teaspoon of salt (you can reduce to ¼ teaspoon for less sodium)
  • ¼ cup Vegetable oil
  • ¾ to 1 cup hot water
  1. Put the flour, salt and baking powder into a bowl. Mix with a fork.
  2. Pour in a little water and a little oil, mixing with a fork. Keep adding oil and water until a dough forms. Stop adding water if it seems too moist. You won’t need all of it.
  3. Put the dough on a lightly floured counter and begin kneading until you have a big ball. If it’s too sticky, add a little more flour.
  4. Divide the dough ball into eight pieces, form into small balls. Set them aside and let them rise for 30-40 minutes, covering them with a dish towel so they won’t dry out.
  5. Preheat your cast-iron skillet to medium heat. Take one dough ball and roll it into an 8 inch sized tortilla. Put the tortilla into the skillet and flip it after 30 seconds. Keep the fried tortillas on a plate and cover lightly so they’ll stay soft.
  6. Fry all the tortillas and serve immediately. If you have leftovers, heat them in the microwave for 10 seconds.

Grains and cereals

Low sodium cereals and pasta-there is a growing number of low sodium cereals and pasta on the market. Read the labels if you’re not sure.


Choose low sodium chips, pretzels, unsalted nuts, and snacks. Foods like fig bars, ginger snaps, popsicles, sherbet, and hard candy are lower in sodium. Instead of buying microwave popcorn, pop our own in the microwave.
