Sodium, Food Labels and Blood Pressure
A Nutrition Facts label can turn “eat less salt” into a concrete comparison. The most useful fields are serving size, sodium milligrams and percent Daily Value—not the package colour or wellness language.
Start with the serving you actually eat
Sodium is listed per labeled serving. If a soup contains two servings and you eat the container, multiply the milligrams and %DV by two. Comparing products only works when the serving amounts are reasonably similar.
Use %DV as a quick screen
FDA describes 5% Daily Value or less per serving as low and 20% or more as high. That rule helps compare breads, sauces, soups, snacks and prepared meals. It does not mean every food above 20% is forbidden; it shows where a large share of the day can accumulate.
Claims are comparisons, not verdicts
“Reduced sodium” means less than a reference product, which can still leave a substantial amount. “No salt added” does not necessarily mean sodium-free because ingredients may naturally contain sodium. Read the Nutrition Facts panel after reading the claim.
Find the repeat contributors
A food need not taste very salty to contribute. Bread, sandwiches, pizza, cured meat, cheese, soups, sauces and restaurant food can add up through frequency and portions. Track two ordinary days to identify repeat sources rather than blaming one occasional snack.
Keep flavour while changing the total
Try garlic, onion, ginger, pepper, smoked paprika, cumin, herbs, citrus or vinegar. Rinse canned beans and vegetables when appropriate. Choose plain frozen vegetables, request restaurant sauces on the side, and combine one salty component with otherwise unsalted ingredients.
Do not improvise with salt substitutes
Some salt substitutes replace sodium with potassium. That can be unsafe with kidney disease or medicines that raise potassium. Ask a clinician or pharmacist before using them routinely.
A better comparison question
Instead of asking whether a food is “good” or “bad,” ask: How much sodium will I eat in my actual portion, how often do I eat it, and is there a version I like with meaningfully less? That preserves choice while making the number useful.
