Choose two soups for one meal
Pick soups you would actually serve. A front claim is a starting clue, not the comparison. Turn both cans around and decide whether you will eat half a can, a whole can, or share it. The canned beans meal guide handles a food you can drain; soup broth is usually part of the bowl.
Match the label basis
Find the stated serving and servings per container. The FDA serving guide explains that a labeled serving is a reference, not a recommendation. Compare the same amount of two soups. A per 100 gram column can help where both packages provide it. Do not compare a small serving on one can with a whole can on the other.
Calculate your actual bowl
If the US panel gives sodium per serving, multiply by the number of labeled servings you will eat. For example, if a hypothetical can says 400 milligrams per serving and your bowl contains two servings, that bowl has 800 milligrams before extras. These are arithmetic examples, not real products. The FDA sodium guide says soups can vary considerably.
Read the local measure
Some markets display salt rather than sodium. The NHS salt guide recommends checking the back or side label for salt. Compare salt with salt or sodium with sodium, using the same food amount. A reduced sodium claim is relative to a reference product and does not by itself show how much is in your bowl.
Decide in the context of the meal
Think about taste, price, serving size and any bread, cheese or other toppings you will add. If sodium is a personal concern, follow your own dietary advice and the actual package. The vegetable meal guide can help build a meal around the soup. This check supports a practical choice, not a guaranteed health result.
