What it tells you

The whole can represents 700 mg of declared sodium. Half the can corresponds to the one-serving amount, assuming the contents are evenly mixed.

Why this reading matters

Nutrition Facts amounts refer to the stated serving. Compare equivalent quantities, distinguish a nutrient amount from its percent Daily Value, and account for how many servings you use. US Food and Drug Administration.

What the label cannot settle

This arithmetic does not set a personal sodium target. Keep the amount in milligrams distinct from salt weight or a percent Daily Value, and follow individual dietary advice if you have it.

Put the check to work

Compare the exact words and amounts on your package with the example. If a panel is missing, a photo is unreadable or the manufacturer has not disclosed a detail, keep that detail as unknown. A different flavor, shade or formulation needs its own check.
