What should you look at first on a nutrition label?

Servings per container, before anything else. Every number below it is per serving, and a package that looks like one portion is frequently labeled as two or three, which silently halves or thirds every figure you are about to read.

What does % Daily Value mean?

It is the share of a daily reference intake, based on a 2,000 calorie diet, that one serving provides. A useful shorthand: 5% or less is low, 20% or more is high. Use it for nutrients you want to limit, like sodium and saturated fat, and for ones you want more of, like fiber.

Is the ingredient list more useful than the nutrition panel?

For some questions, yes. Ingredients are listed by weight, so the first three are most of the product. The panel tells you quantities; the list tells you what the food actually is, and it is the only place that reveals ultra-processing.

How to read a nutrition label in 30 seconds

Four things, in order, and you can ignore the rest of the panel. The serving size trick at the top is where most people get misled before they have started.

Nutrition panels contain about twenty numbers. Four of them do most of the work. Here is the order that gets you to a decision in the aisle.

1. Servings per container, before anything else

This is at the very top, in small type, and it is where the panel misleads people most often.

A 20 oz bottle of soda is frequently labeled as 2.5 servings. A bag of chips that one person finishes is often 3. A pint of ice cream can be 4. Every number below is per serving, so if you eat the package and read the panel, you have understated everything by a factor of two to four without noticing.

Multiply first. Then read.

2. Added sugars, not total sugars

Two sugar lines, and only one is the point.

Total Sugars includes what naturally occurs in fruit, milk and vegetables. Plain yogurt shows 7 g and none of it was added.

Includes X g Added Sugars is what guidance is aimed at. The 2026 US guidelines give a working ceiling of 10 g per meal, which most sweetened products clear on their own.

3. Sodium

The shorthand is %DV: 5% or less is low, 20% or more is high.

One useful rule for single-item meals, soup, frozen dinner, sandwich, is that sodium in milligrams should ideally be no higher than the calories. A 300 calorie soup with 900 mg of sodium is triple that ratio.

4. Fiber

The one number where more is straightforwardly better, and the one most people fall far short on. Above 3 g per serving is decent; above 5 g is good.

For bread and cereal, fiber is also the fastest proxy for whether "whole grain" on the front means anything. Real whole-grain bread lands at 3–5 g a slice. Bread that is white flour with caramel coloring lands at 1 g regardless of what the packaging says.

Then flip it over

The ingredient list answers a different question than the panel, and sometimes a more important one.

Ingredients appear in order of weight: so the first three are most of the product. If sugar in any of its forms appears in the first three, it is a sugar product. If the list runs past a dozen items containing things you could not buy individually, you are looking at an ultra-processed food regardless of what the numbers say.

The panel tells you how much is in it. The list tells you what it is.

What the panel cannot tell you

It cannot tell you about a meal you cooked, which is most of what people actually eat. It cannot tell you about a restaurant plate. And it cannot tell you about the two-thirds of a package you ate rather than the labeled serving.

That gap is the entire reason photo-based logging exists, not because labels are wrong, but because most food does not come with one.
