Are you eating too much sodium?

Americans eat more than 3,400 milligrams of sodium per day on average, according to the Food and Drug Administration (FDA). That’s 1,000 mg more than the USDA’s daily recommended value for healthy adults and nearly 2,000 mg more than the American Heart Association recommends for optimal heart health. The FDA recommends that healthy adults eat less than 2,300 mg of sodium a day or about 1 teaspoon, and yet the average American eats 5 or more teaspoons each day.

A high sodium intake can increase your risk of developing high blood pressure and heart disease. While eating less sodium is widely recommended for people already diagnosed with high blood pressure and heart disease, a low sodium diet can also help lower the risk of stroke, heart attack, and other cardiovascular conditions for healthy adults, according to the Centers for Disease Control and Prevention.

Because blood pressure typically rises with age, reducing sodium intake may be particularly important for older adults. Reducing daily sodium intake to 1,500 mg lowers blood pressure even more than the general 2,300 mg recommendation, according to the FDA.

Chances are, you are eating more sodium than you know. Where is all of that sodium coming from? It’s not the saltshaker on the table. Restaurant, processed, and prepackaged foods like frozen meals account for more than 75 percent of the sodium that Americans eat. Sodium is widely used in packaged foods to preserve, thicken, or enhance flavor. Even foods that don’t taste salty may have high levels of sodium.

Not all frozen meals are created equal. A single slice of frozen pizza can pack a whopping 370 to 730 mg of sodium and more than 300 calories. Many meals have more sodium and fat than you should eat in the entire day.

The Cleveland Clinic recommends you look for frozen meals that have less than 600 mg of sodium, less than 500 calories, and less than 3 grams of saturated fat. Be careful to avoid “empty calories,” or meals that are low in protein, vitamins, and minerals. Meals packed with vegetables and whole grains will keep you full longer and have a higher nutritional value. Avoid meals with added sugar and high fat content.

With a quick look at the nutrition facts and ingredients, you can choose a healthy, heart-friendly meal from the freezer isle.

To find heart-healthy frozen meals, the University of Pittsburgh Medical Center recommends looking for low-sodium varieties with less than 300 mg per serving and no more than 500 calories. Depending on your sodium intake the rest of the day, you may be able to increase your intake to 600 mg per frozen meal and still meet your daily sodium goal. Ignore the percent daily value of sodium on the nutrition label and instead focus on the total milligrams in each serving.

Be sure to always read the nutrition facts to avoid hidden sodium in packed and frozen foods. Packages that say “reduced sodium” or “25 percent less sodium” may still be high in sodium. Always check the milligrams in each serving and how many servings are in a package to avoid eating excess sodium. Ingredients like salt, sodium bicarbonate (baking soda), sodium nitrite, sodium benzoate, and monosodium glutamate (MSG) all contribute added sodium and are included in the total milligrams.
