What Is on the Food Label?
The two leading U.S. food label authorities are the Food Safety and Inspection Services (FSIS), which is part of the U.S. Department of Agriculture, and the Food and Drug Administration (FDA), which is part of the U.S. Department of Health and Human Services. The FSIS regulates labeling on meat and poultry products, while the FDA regulates the labeling and ingredients of just about all other food products.
Food labels are required on most prepared foods such as bread, cereal, canned and frozen foods, snacks, desserts, and drinks. Nutrition labeling is voluntary on fruits, vegetables, meat, poultry and fish. Nutrition labels are not required on foods that contain few significant nutrients, such as coffee and tea, or on certain ready-to-eat foods such as unpackaged deli foods, bakery items, and restaurant foods.
Food labels contain up to four different types of useful nutritional information to help you make healthier choices:
Below those are listed a few micronutrients, two vitamins, and two minerals, which are displayed in percentages. On the right side of the label is a column headed "Percent Daily Value." Near the bottom of the label is a footnote stating that the Percent Daily Values are based on a 2,000-calorie diet that includes a list of Daily Reference Values.
Serving Size
The place to start when looking at the Nutrition Facts Panel is the serving size and the number of servings in the package. Serving sizes are provided in familiar units, such as cups, tablespoons, or pieces, followed by the metric measure. The serving sizes are based on the amounts of food that people normally eat, making it more realistic and easier to compare with similar foods. The serving size is the first item you should look at; all the nutrition information on the label pertains to the serving size stated on the label.
ALERT! Be aware that if you purchase a product because you feel it is low in a nutrient such as fat or calories, you should make sure the serving size is an amount you will realistically eat. If you don't follow the serving size, it may not be low in that nutrient anymore.
On the sample label shown above, the serving size is 1/2 cup, and there are four servings per container. That means that all the information pertains to 1/2 cup. If you ate the whole container, you would need to multiply all of the information on the label by four.
Calories and Calories from Fat
Calories per serving measures how much energy you would receive from a single serving of a food. The label also provides the number of calories in one serving that come from fat. In the example label, there are 90 calories in a serving, and there are 30 calories from fat. This means that out of the total 90 calories per serving, 30 (or a third of them) are coming from fat. We know that calories in food only come from three sources: fat, protein, and carbohydrate. So this also tells you that the other 60 calories are coming from protein and/or carbohydrate sources. Now, if you ate the whole package, you would consume a total of four servings of the food, or 360 calories, with 120 calories from fat.
Nutrients on the Label
The specific nutrients listed on the Nutrition Facts Panel were selected because of their relationship to current health issues. Nutrients that are required on all food labels include total fat, saturated fat, cholesterol, sodium, total carbohydrate, dietary fiber, sugar, protein, vitamin A, vitamin C, calcium, and iron. Manufacturers can add additional nutrients, but the ones listed are required, Americans generally consume too much of the first four nutrients on the list.
The total fat content consists of both types of fat: saturated and unsaturated (polyunsaturated and monounsaturated). Under total fat, these fats are separated out. Only saturated fat is required to be listed; unsaturated can be listed but is not required. Saturated fat is required because people should be aware of their intake. Lowering your intake of saturated fat can decrease your risk of heart disease.
Cholesterol and sodium are the other two nutrients that most Americans generally consume too much of. Lowering cholesterol can benefit heart health, and for some people, lowering sodium can help decrease the risk for high blood pressure. Both of these nutrients are measured in milligrams.
Fact: Most Americans do not get enough dietary fiber, vitamin A, vitamin C, calcium, or iron. Including enough of these nutrients in your daily diet can help improve health and reduce the risk of some diseases and conditions.
The two vitamins and minerals on the list are referenced as Reference Daily Intakes (RDIs). The RDI values are established by the Food and Drug Administration (FDA) and are used only on food labels. Initially the values on food labels were based on the highest 1968 RDA for each nutrient, to ensure that needs for all groups were met. RDI replaces the term "U.S. RDA," which was introduced in 1973 as a label reference value for vitamins, minerals, and protein in voluntary nutrition labeling. The name change was completed because of confusion that existed over U.S. RDAs -- the FDA values used on food labels -- and RDAs. The RDIs were put into effect when the new food labels emerged in 1992.
The food label should be used to help limit those nutrients you should cut back on, and to increase those nutrients you should consume more of.
Percent Daily Value
The nutrients on food labels are expressed in two distinct ways: in terms of the amount by weight per serving, using grams or milligrams, or in terms of Percent Daily Value. The Percent Daily Value is an estimate of how a serving of the food meets the daily requirement for each nutrient, based on a 2,000-calorie diet. This is meant to help you decide whether a specific nutrient in a serving of food contributes a lot or a little to your total daily intake. Your daily goal should be to meet 100 percent or less of the daily value for nutrients; you should be consuming less fat, saturated fat, sodium, sugar, and cholesterol. Likewise, your goal should be to get at least 100 percent or more of nutrients you should be consuming more of, such as fiber, complex carbohydrates, calcium, iron, vitamin A, and vitamin C.
Alert! Be careful not to be confused by Percent Daily Values. The value does not indicate how much a nutrient is in a food. It simply means how the food, per serving, compares to your total daily nutritional intake. For example, if a food states 5 percent daily value for fat, that does not mean there is 5 percent fat in the product. It does mean that the product is using up 5 percent of your daily fat needs for the day.
Personalized Calorie Levels
If you consume less or more than 2,000 calories, the daily value can be adjusted for your specific calorie level. Use the table below to find out how you can adjust the total Percent Daily Values for specific calorie levels. If you were on a 1,600-calorie diet -- 20 percent less than the standard 2,000 calories -- you would figure your daily value to total only 80 percent for the day, a 20-percent reduction. The nutrients you would adjust are total fat, saturated fat, carbohydrate, and dietary fiber. Cholesterol and sodium are always the same amount, no matter how many calories you ingest, so figure for these to always add up to 100 percent each day.
Adjusted Percent Daily Value for Specific Calorie Levels
| Calories | Adjusted Percent Daily Value |
| 1,400 | 70 percent |
| 1,600 | 80 percent |
| 2,000 | 100 percent |
| 2,200 | 110 percent |
| 2,500 | 125 percent |
| 2,800 | 140 percent |
| 3,200 | 160 percent |
To find out your recommended amounts for certain nutrients for your personalized calorie intake, follow the values in the table below.
Even though you may not know exactly how many calories you eat in a day, you can still use the Percent Daily Value as a frame of reference.
| Nutrient | Calories* | ||||||
| 1,400 | 1,600 | 2,000 | 2,200 | 2,500 | 2,800 | 3,200 | |
| Total Fat (g) | 47 | 53 | 65 | 73 | 80 | 93 | 107 |
| Saturated Fat (g) | 16 | 18 | 20 | 24 | 25 | 31 | 36 |
| Cholesterol (mg) | 300 | 300 | 300 | 300 | 300 | 300 | 300 |
| Sodium (mg) | 2,400 | 2,400 | 2,400 | 2,400 | 2,400 | 2,400 | 2,400 |
| Total Carbohydrate (g) | 210 | 240 | 300 | 330 | 375 | 420 | 480 |
| Dietary Fiber** (g) | 20 | 20 | 25 | 25 | 30 | 32 | 37 |
*These calorie levels may not apply to children and adolescents, who have changing calorie requirements. For specific advice concerning personal calorie levels, consult your doctor or a registered dietitian.
**20 grams is the minimum amount of fiber recommended for all calorie levels below 2,000.
How Percent Daily Value Is Calculated
The Percent Daily Values are calculated using the reference values in the footnote of each food label. These values are the same on every food label. The daily reference values listed are calculated based on both a 2,000- and a 2,500-calorie diet. The daily values that are actually listed on the label use the Daily Reference Intake values for the 2,000-calorie diet.
Do you need to know how to calculate percentages to follow this advice? No, the Percent Daily Value does the math for you. It helps you to interpret what the amounts mean (grams and milligrams) by placing them all on the same type of scale (0-100 Percent Daily Value). This helps you tell high from low and understand which nutrients may be contributing a lot or a little to your daily recommended allowance.
The daily value amount of the nutrient, per serving, is calculated by dividing the reference value to see how much of your nutrient allotment is used up for the day. The following example illustrates how to calculate daily value for a food containing 3 grams of fat per serving:
Sugar and Protein
Sugars and protein do not have a Percent Daily Value on the Nutrition Facts Panel. Sugar has no daily reference value because no recommendations have been made for the total amount of sugars to eat in a day. The sugar on the label includes naturally occurring sugars, such as those in fruit and dairy products, as well as added sugars, such as those in soft drinks and baked goods. Check the ingredient list to find more information on added sugars.
You will not always see a Percent Daily Value for protein. It is only required if a claim is made for protein, such as "high in protein," or if the food is specifically meant for use by infants and children under four years old. The government has decided that current scientific evidence indicates that protein intake is not a public health concern for adults or for children over age four. Protein needs are more individualized and should really be based on an individual's weight and physical activity.
Fact: If the Percent Daily Value of protein is required, it is calculated as 10 percent of total calorie intake. On a 2,000-calorie diet, this would equal 50 grams of protein. The minimum amount of protein recommended for all calorie levels is 46 grams.
Quick Guide to Percent Daily Values
To help you quickly decide whether a food is high or low in a nutrient, use this general guide:
Footnote to the Food Label
The asterisk used after the heading "Percent Daily Value" refers to the footnote in the lower part of the nutrition label. This section tells you that Percent Daily Values are based on recommendations for a 2,000-calorie diet and that your daily values may be higher or lower, depending on your calorie needs. This statement is required on all food labels. The remaining information in the full footnote, including the daily reference values for 2,000- and 2,500-calorie diets, as well as the calories per gram of the three macronutrients, may not be on the package if the label is small. When the full footnote does appear on a label, it will always be exactly the same. It doesn't change from product to product because it shows dietary advice for all Americans, not information about a specific food product.
Nutritional Claims
Labels often contain claims of desirable levels of individual nutrients. Regulations now strictly spell out what terms may be used to describe the level of a nutrient in a food and how those terms can be used. Nutrition claims can be used as another valuable tool that can help you to choose foods that are lower in calories, fat, cholesterol, and sodium, and higher in fiber, vitamins, and minerals. Some of the general claims used include the following:
The ingredient label is vital to people who are allergic to certain foods and/or additives. To help these people avoid problem ingredients, the ingredient list must include the following, when appropriate:
Tips on the Food Label
It is important to use the food label for a number of reasons. It takes some practice, but once you begin to make reading the label a habit, it is hard not to use it. Keep these tips in mind when reading food labels:
