You don't need to memorize daily values or study nutrition science. Four checks (serving size, calories, %DV, and a short list of nutrients) get you through any package in under a minute.
Create Your Own Nutrition Facts Label →Start with the serving size, check calories per serving, then use % Daily Value to judge each nutrient: 5% DV or less is low, 20% DV or more is high. Watch saturated fat, sodium, and added sugars closely, and look for fiber, vitamin D, calcium, iron, and potassium.
Every U.S. package carries some version of this panel. The layout is standardized by the FDA, so once you know what each block means, you can read any product's label the same way.
How much food the numbers below actually represent, not necessarily what you'll eat.
Energy per serving. Multiply by servings eaten to get your real total.
Saturated fat, sodium, and added sugars: look for lower %DV here.
Fiber, vitamin D, calcium, iron, potassium: higher %DV is generally better.
Shows whether a nutrient is low or high. 5% or less = low. 20% or more = high.
Total carbohydrate, broken into dietary fiber, total sugars, and added sugars.
Grams per serving, used for building and repairing body tissue.
Key micronutrients with both an amount and a %DV.
If you only have a few seconds in the aisle, work through the panel top to bottom in this sequence.
Find out how much food the numbers below actually represent.
Shown per serving, not necessarily for the whole package.
Use %DV to see if a nutrient is relatively low or high.
Saturated fat, sodium, and added sugars.
Fiber, vitamin D, calcium, iron, potassium.
See what the product is actually made from.
Nearly every number on the label is based on the stated serving size. If a label lists 1 cup / 250 calories and you eat two cups, you've consumed roughly 2 × 250 = 500 calories, and the same scaling applies to fat, sodium, carbohydrate, fiber, and protein.
Serving size ≠ portion size. Serving size is the standardized amount used to build the label; portion size is however much you actually eat. And no: serving size is not a recommendation. Per the FDA, it's based on amounts people typically consume, not amounts you should eat.
Ten fields make up the bulk of the panel. Each one below is tagged as something to watch for a limit (red), something to seek out more of (green), or a neutral reference number (gray-green).
Energy per serving. Three servings at 230 calories each means 690 calories for the package, which is why checking calories before serving size is misleading. The familiar "2,000 calories a day" footnote is a general reference for labeling, not a personal target; individual needs vary by age, sex, size, and activity.
%DV shows how much one serving contributes toward a full day's worth of that nutrient. You don't need to memorize each Daily Value, just the 5/20 rule.
DV or less is considered low in that nutrient per serving.
DV or more is considered high in that nutrient per serving.
For nutrients to limit, look for a lower %DV. For nutrients you want more of, look for a higher %DV.
Total Fat is listed in grams, with Saturated Fat and Trans Fat broken out underneath for more context. Saturated fat is one of the nutrients the FDA recommends limiting.
Trans fat has no established %DV on the label; compare products using the gram amount directly.
Listed in milligrams with a %DV. The same 5/20 rule applies: 5% DV or less is low, 20% DV or more is high.
Measured in milligrams. The FDA Daily Value is under 2,300mg per day for adults and children age 4+. A serving at 460mg is 20% DV, high under the 5/20 rule. Eat two servings and you've taken in 920mg, so recheck serving size before you judge a sodium number.
Grams of carbohydrate per serving, broken into Dietary Fiber, Total Sugars, and Added Sugars beneath it.
One of the nutrients the FDA flags as under-consumed. Useful for comparing similar products (bread, cereal, pasta, wraps, bars, crackers) when serving sizes line up.
This is the most commonly misread line on the label. Added Sugars are already counted inside Total Sugars; never add the two together.
Naturally occurring sugars come from foods like fruit and milk. Because Added Sugars carry their own Daily Value, a product at 24% DV added sugars is high per the 5/20 rule.
Shown in grams; a %DV isn't required on every label. When comparing two products, check that serving sizes match: 15g protein per 100g isn't equivalent to 15g protein per 200g.
Listed with both an amount and a %DV: the four micronutrients the FDA highlights as ones many people should get more of.
Lower %DV is generally better for these three.
Higher %DV moves you further toward your daily needs.
Ingredients are listed in descending order by weight: the first ingredient makes up more of the product than every ingredient that follows it.
How much of certain nutrients the food provides per serving.
What the food was actually made from, ordered by weight.
Whole wheat flour is present in a greater amount by weight than everything listed after it. Reading both the panel and the ingredients gives a fuller picture than either alone.
A single product can be high in a nutrient you want more of and a nutrient you want to limit, which is exactly why you read the whole panel, not one number.
All figures apply to one cup. Eat two, and most amounts roughly double.
240 per serving; ≈480 for two servings.
10% DV: between low and high.
21% DV: high in sodium per serving.
21% DV: high in dietary fiber.
10% DV: between low and high.
20% DV: high in calcium.
The takeaway: this product is high in fiber and calcium, but also high in sodium. Judge the whole label in the context of your day, not any single line.
Labels are most useful when you put two similar products next to each other. Both cereals below use the same 40g serving size, so the numbers compare directly.
| Nutrition | Cereal A | Cereal B |
|---|---|---|
| Serving size | 40g | 40g |
| Calories | 160 | 170 |
| Sodium | 7% DV | 14% DV |
| Dietary fiber | 18% DV | 25% DV |
| Added sugars | 20% DV | 8% DV |
| Protein | 5g | 7g |
Cereal A runs slightly lower in calories and sodium. Cereal B brings more fiber and protein with less added sugar. Neither is universally "better"; it depends what you're prioritizing. If the two labels used different serving sizes, you'd need to scale one before comparing at all.
Some packages show nutrition per serving and per container side by side. If you're going to eat the whole thing, read the right-hand column.
| Per Serving | Per Container | |
|---|---|---|
| Calories | 200 | 400 |
| Total fat | 8g | 16g |
| Sodium | 300mg | 600mg |
| Added sugars | 8g | 16g |
20% DV or more per serving is high. Check servings-per-container too: eating several servings adds up fast.
Never add Added Sugars to Total Sugars; they're already included.
20% DV or more per serving counts as high in fiber.
Double the serving eaten, roughly double the listed calories.
Only compare products using equivalent or similar serving sizes.
A package often holds several servings even if you'd call it one portion.
Calories cover energy, not the rest of the nutrition picture.
Added Sugars are already inside the Total Sugars figure.
It's a standardized reference amount, not a recommendation.
You only need the 5/20 rule; no need to memorize every Daily Value.
Always check that two products use the same serving size before comparing.
Front-of-package claims are marketing. Turn it over for the real numbers.

| Calories | Energy per serving | Multiply for multiple servings |
| % Daily Value | Contribution toward daily needs | 5% = low · 20% = high |
| Saturated fat | Sat. fat per serving | Look for lower %DV |
| Sodium | Sodium per serving | Look for lower %DV |
| Dietary fiber | Fiber per serving | Higher %DV helps meet daily needs |
| Total sugars | All sugars, natural + added | Includes added sugars |
| Added sugars | Sugars added per FDA definition | Look for lower %DV |
| Protein | Protein per serving | Compare using similar portions |
| Vitamin D / Calcium / Iron / Potassium | Key micronutrients | Higher %DV provides more |
Check the serving size, then calories, then use %DV to evaluate nutrients. 5% DV or less is low, 20% DV or more is high. Pay close attention to saturated fat, sodium, added sugars, fiber, vitamin D, calcium, iron, and potassium.
Serving size. Nearly every other number on the label is based on it.
A shortcut for reading %DV: 5% DV or less is considered low in that nutrient, 20% DV or more is considered high.
No. Added Sugars are already included inside Total Sugars. 15g Total Sugars with 5g Added Sugars means 15g total, not 20g.
Check the sodium %DV. 20% or more per serving is high; 5% or less is low.
A %DV for protein isn't required on every label; many products show only the gram amount.
No. It's based on amounts people typically consume, used to standardize labeling, not a personal recommendation.
Match the serving sizes first. If they're equal or similar, compare calories, %DV, and nutrient amounts relevant to your needs.
Limit saturated fat, sodium, and added sugars. Get more of dietary fiber, vitamin D, calcium, iron, and potassium.
Start with serving size. Check calories per serving. Use % Daily Value: 5% DV or less is low, 20% DV or more is high. Keep an eye on saturated fat, sodium, and added sugars; look for fiber, vitamin D, calcium, iron, and potassium. Then check the ingredients and make sure you're comparing equivalent serving sizes. That's the whole system; most labels take under a minute once it's automatic.
Turn your nutritional data into a properly formatted, FDA-style Nutrition Facts label.
