You’ve likely heard that many Americans consume excessive sodium. While a small amount of sodium is crucial for bodily functions, too much can negatively impact your health. Diets rich in sodium are linked to a higher risk of developing high blood pressure, a significant contributor to stroke and heart disease.
Contrary to popular belief, over 70% of dietary sodium originates from packaged and prepared foods, not from table salt added during cooking or at the table. The prevalence of sodium in the food supply makes it challenging for Americans to reduce their sodium intake. The U.S. Food and Drug Administration is collaborating with the food industry to implement reasonable sodium reductions across a diverse range of foods. Even with sodium already present in many packaged foods, you can manage your daily sodium consumption by utilizing the Nutrition Facts label.
Deciphering the Nutrition Facts Label
The Nutrition Facts label is a valuable tool for making informed food choices.
-
Understanding the Daily Value (DV). Daily Values represent reference amounts for nutrient intake or limits to avoid exceeding daily. The Daily Value for sodium is less than 2,300 milligrams (mg) per day.
-
Utilizing % Daily Value (%DV). The %DV indicates the percentage of the Daily Value for each nutrient in a single serving, illustrating the nutrient’s contribution to your overall daily diet.
Employ the %DV to determine whether a food serving is high or low in sodium, and to compare and select foods to consume less than 100% DV of sodium daily.
As a rule of thumb: 5% DV or less of sodium per serving is considered low, while 20% DV or more of sodium per serving is considered high.
-
Paying Attention to Servings. The nutritional information on the Nutrition Facts label is typically based on a single serving. Check the serving size and the number of servings you consume to accurately assess your sodium intake.
Key Food Sources of Sodium
According to the Centers for Disease Control and Prevention (CDC), approximately 40% of sodium consumption in the U.S. stems from these common foods:
- Deli Meat Sandwiches
- Pizza
- Burritos and Tacos
- Soups
- Savory Snacks (e.g., Chips, Crackers, Popcorn)
- Poultry
- Pasta Mixed Dishes
- Burgers
- Egg Dishes and Omelets
Sodium content can differ significantly among similar foods. Compare products using the Nutrition Facts label, and remember to check serving sizes for accurate comparisons.
Table Salt vs. Sodium: Clarifying the Difference
The terms “table salt” and “sodium” are often used interchangeably but are distinct. Table salt (sodium chloride) is a crystalline compound abundant in nature. Sodium is a mineral and a chemical element within salt.
The Role of Sodium in Food
Sodium serves multiple purposes as a food ingredient: curing meat, baking, thickening, retaining moisture, enhancing flavor (including other ingredients), and acting as a preservative. Common food additives like monosodium glutamate (MSG), sodium bicarbonate (baking soda), sodium nitrite, and sodium benzoate also contain sodium and contribute (in smaller amounts) to the total sodium listed on the Nutrition Facts label.
Surprisingly, some foods without a salty taste can still be high in sodium. Taste alone isn’t a reliable indicator of a food’s sodium content. While some sodium-rich foods like pickles and soy sauce taste salty, others like cereals and pastries contain sodium but don’t taste salty. Even foods consumed frequently in small servings, like breads, can accumulate significant sodium intake throughout the day.
Decoding Nutrient Claims on Packaging
Nutrient claims on food and beverage packages can help quickly identify options with lower sodium content. Here’s a breakdown:
| Claim | Meaning |
|---|---|
| Salt/Sodium-Free | Less than 5 mg of sodium per serving |
| Very Low Sodium | 35 mg of sodium or less per serving |
| Low Sodium | 140 mg of sodium or less per serving |
| Reduced Sodium | At least 25% less sodium than regular product |
| Light in Sodium/Lightly Salted | At least 50% less sodium than regular product |
| No-Salt-Added/Unsalted | No salt added during processing (may not be sodium-free unless stated) |
The Connection Between Sodium and Blood Pressure
Sodium’s water-attracting properties cause it to draw water into the bloodstream, increasing blood volume and, consequently, blood pressure. High blood pressure (hypertension) is a condition where blood pressure remains elevated over time. Hypertension forces the heart to work harder, and high blood pressure can damage arteries and organs (heart, kidneys, brain, and eyes). Uncontrolled high blood pressure increases the risk of heart attack, heart failure, stroke, kidney disease, and blindness. Blood pressure generally rises with age, making sodium intake management increasingly vital.
Understanding Your Sodium Intake
Sodium is an essential nutrient in small amounts (provided substantial sweating does not occur) to maintain fluid balance and support muscle and nerve function. However, most Americans consume excessive amounts, often unknowingly.
The average American consumes approximately 3,400 mg of sodium per day. The Dietary Guidelines for Americans recommends adults limit sodium intake to less than 2,300 mg per day, equivalent to about 1 teaspoon of table salt! Recommended limits are even lower for children under 14.
10 Practical Tips for Reducing Sodium Intake
Understanding sodium in foods and discovering new preparation methods can help you meet your sodium goals. By implementing these tips, your preference for sodium will gradually decrease, and you may not even miss it:
- Read the Nutrition Facts label: Compare food options to ensure you consume less than 100% DV (less than 2,300 mg) of sodium each day.
- Prepare food at home whenever possible: Reduce your intake of packaged sauces, mixes, and “instant” products (including flavored rice, instant noodles, and ready-made pasta).
- Enhance flavor without adding sodium: Minimize the use of table salt when cooking, baking, or at the table. Use no-salt seasoning blends and herbs and spices instead of salt to add flavor.
- Opt for fresh ingredients: Choose fresh meat, poultry, and seafood over processed options. Check for added salt water or saline in fresh meat and poultry packaging.
- Pay attention to your vegetables: Choose fresh, frozen (without sauce or seasoning), or low-sodium or no-salt-added canned vegetables.
- Rinse canned foods: Rinse sodium-containing canned foods like beans, tuna, and vegetables before eating to remove some of the sodium.
- Choose unsalted snacks: Opt for low-sodium or no-salt-added nuts, seeds, and snack products (such as chips and pretzels), or consider carrot or celery sticks.
- Be mindful of condiments: Sodium in condiments can accumulate. Choose light or reduced-sodium condiments, use oil and vinegar on salads instead of bottled dressings, and use only a small amount of flavoring from seasoning packets.
- Reduce portion sizes: Less food means less sodium. Prepare smaller portions at home and consume less when eating out. Choose smaller sizes, split an entrée with a friend, or take home leftovers.
- Make low-sodium choices at restaurants: Request that meals be prepared without table salt and ask for sauces and salad dressings to be served “on the side” for controlled use. Inquire about available nutrition information to choose lower-sodium options.
By following these guidelines, you can effectively manage your sodium intake and promote better health.
