Compare the sodium in the soup you buy.
A carton of soup can make lunch easier. The label can also answer a more useful question than whether its name sounds wholesome.

Compare the same amount
Check whether the sodium figure is for a serving or the whole container. If you will eat more than the labelled serving, take that into account. [1]
Compare similar soups in the same units, then think about what else goes with lunch. Bread, sauces and other foods may contribute sodium too.
A lower-sodium option that you enjoy is more useful than buying a product you never want to finish.
Leave room for personal advice
Lower-sodium choices feature in the DASH eating plan. [2] That does not mean a soup label can diagnose high blood pressure or set a suitable daily target for everyone.
People with kidney disease may need advice about several nutrients, not sodium alone. [3]
For an ordinary shopping trip, begin with two similar products and one clear comparison. You do not need to redesign the entire diet in the soup aisle.
Sources, evidence and limits
Evidence basis
[1] FDA — Understanding food labels
Serving-size and key-nutrient sections read.
Compare like quantities; label servings are not individual prescriptions. US label explanation is not Malaysian law.
[2] NHLBI — DASH eating plan
Full main public guidance page read.
Overall pattern and sodium matter; no personal prescription made.
[3] NIDDK — Eating with chronic kidney disease
Main nutrition and individualisation sections read.
Requirements depend on stage, treatment and the person.
Least certain: A product comparison does not establish the individual’s optimal sodium intake.
Contrary evidence and limits: Convenience soups can be useful; disease-specific restrictions may involve potassium, fluids or other nutrients.
What would change the conclusion: A clinician’s target or a different serving amount changes the interpretation.
Claims not adopted: No universal sodium target, kidney-protective soup claim or diet-ranking percentage.
