A nutrition label is the standardized panel of information found on nearly every packaged food and beverage sold in the United States. Required by the FDA, it lists calories, serving size, and key nutrients so you can compare products and make informed choices about what you eat. The current version of the label was updated in 2016, with most manufacturers required to comply by 2020.
What the Label Includes
Every Nutrition Facts label follows the same top-to-bottom structure. It starts with serving information: how many servings are in the package and how large each serving is. Below that, calories per serving are displayed in large, bold type. The rest of the label breaks down the nutrients in that single serving.
The mandatory nutrients, listed in grams or milligrams, are:
- Total Fat (with saturated fat and trans fat listed underneath)
- Cholesterol
- Sodium
- Total Carbohydrate (with dietary fiber, total sugars, and added sugars listed underneath)
- Protein
- Vitamin D, Calcium, Iron, and Potassium
Vitamins A and C used to be required but are now optional. The swap reflects shifting public health priorities: deficiencies in vitamin D and potassium are more common today, so regulators made those mandatory instead.
Serving Size vs. Portion Size
The serving size at the top of the label is not a recommendation for how much to eat. By law, it has to reflect the amount people typically consume in one sitting. If most people eat a cup of cereal at a time, the serving size is one cup, regardless of whether a dietitian would suggest more or less.
This matters because every number on the label is tied to that serving. If the serving size is 10 chips and you eat 30, you need to triple everything: calories, sodium, fat, all of it. The label itself won’t warn you about this, so checking the serving size first saves you from misleading math.
How % Daily Value Works
To the right of most nutrients you’ll see a percentage. This is the % Daily Value (%DV), which tells you how much one serving contributes to a full day’s intake based on a 2,000-calorie diet. A quick rule: 5% DV or less is considered low, and 20% DV or more is high.
Not every nutrient gets a %DV. Trans fat and total sugars don’t have one. Protein only shows a %DV if the manufacturer makes a claim like “high in protein” on the packaging. The footnote at the bottom of the label clarifies the 2,000-calorie baseline, though your own needs may be higher or lower depending on age, sex, and activity level.
The %DV is useful for comparing two products side by side. If one brand of crackers shows 15% DV for sodium and another shows 4%, the difference is immediately clear without doing any gram-to-gram calculations yourself.
Total Sugars vs. Added Sugars
One of the most significant recent changes to the label is the separation of total sugars and added sugars. Total sugars include everything: the naturally occurring sugar in milk, fruit, and other whole ingredients, plus any sugar introduced during manufacturing. Added sugars are only the sugars put in during processing, things like table sugar, honey, syrups, and concentrated fruit juices used as sweeteners.
The label uses the word “includes” before added sugars to show that they’re a subset of total sugars, not a separate category stacked on top. Federal dietary guidelines recommend keeping added sugars below 10% of your total daily calories, which is roughly 50 grams on a 2,000-calorie diet. Having added sugars broken out lets you see whether a product’s sugar comes from its core ingredients or from extra sweeteners.
What Changed in the Latest Update
The FDA overhauled the Nutrition Facts label in 2016 with several practical changes. Calorie counts and serving sizes are now printed in larger, bolder type so they’re easier to spot. “Calories from Fat” was removed entirely because research shows the type of fat matters more than the total amount. And the daily values for several nutrients, including sodium, dietary fiber, and vitamin D, were recalculated based on newer science.
Products that could reasonably be eaten in one sitting or across multiple sittings, like a 20-ounce bottle of soda or a pint of ice cream, now require dual-column labels. One column shows the nutrition for a single serving, and the other shows it for the entire package. This eliminates the common trick of listing a container as two or three servings when most people consume the whole thing at once.
The Ingredient List
Separate from the Nutrition Facts panel but usually right next to it, the ingredient list names every component in the product. Ingredients are listed in descending order by weight, so whatever appears first makes up the largest proportion of the food. If sugar or a synonym for sugar (corn syrup, dextrose, maltose) shows up in the first few positions, it’s a major part of the product.
Which Foods Are Exempt
Not every food product carries a Nutrition Facts label. Small businesses that employ fewer than 100 full-time workers and sell fewer than 100,000 units of a product per year can file for an exemption, though they lose that exemption if they make nutrition claims on the packaging. Retailers with annual gross sales of $500,000 or less, or food-specific sales under $50,000, are also exempt without needing to file paperwork.
Fresh produce, raw fish, and certain other unpackaged foods are generally not required to carry a label, though many grocery stores voluntarily display nutrition information on signs or shelf tags near those items.
