Reading a nutrition label like a clinician
Most people scan for calories and stop. Here's the order a dietitian actually reads a label in.
Serving size is the first line worth checking, not the last — every other number on the label is calculated against it, and a package that looks reasonable at a glance can represent 2-3 servings, quietly multiplying every other figure.
The ingredient list, ordered by weight, tends to be more informative than the nutrition facts panel for judging overall food quality — an ingredient list topped by sugar, refined flour, and oil tells a different story than one topped by whole food ingredients, even if the calorie counts look similar.
Added sugar (now broken out separately from total sugar on US labels) is generally the more clinically relevant number than total sugar, since total sugar includes naturally occurring sugars in fruit or dairy that come with other nutritional value attached.
Sodium and saturated fat percentages are worth checking against personal health context specifically — the standard %DV is calculated for a general 2,000-calorie population baseline and may not reflect an individual's actual target, particularly for anyone managing blood pressure or cardiovascular risk.
