Using the Nutrition Facts Label

Your body needs food for fuel. Foods with certain nutrients do a better job of fueling your body than other foods. How can you learn what is in the foods you eat? Look at the Nutrition Facts label.

The Nutrition Facts label, found on all packaged foods, follows guidelines set by the U.S. Food and Drug Administration (FDA). The information on the label gives you the information you need to make good food choices.

In 2016, the FDA changed the requirements for information on the nutrition facts label to reflect new scientific information and to make the label easier for people to use and understand.

Many manufacturers are already using the new label. Large food manufacturers must switch to the new label by January 1, 2020. Smaller food manufactures must switch by January 1, 2021.

Changes to the new label include:

  • Making the calories and serving size font larger and bolder so it’s easier to read.
  • Updating the serving size to reflect amounts that people realistically eat and drink.
  • In addition to overall sugars, listing the amount of added sugars in a serving.
  • Listing the amount of Vitamin D and potassium in a serving.
  • The footnote at the bottom of the label has changed to better explain the meaning of % Daily Value.

The rest of the information in this article applies to the new Nutrition Facts label.

Understanding Each Section of the Food Label

Serving Size

The top of the Nutrition Facts label tells you the serving size and the number of servings in the container or package.

If you are keeping track of your calories or nutrient intake, make sure to take into account the amount of the food you actually eat. People often eat more than a single serving size at one time.

For example, if a serving is one cup but you eat two cups, you need to double the amounts listed on the label to accurately measure what you ate. You may find it helpful to measure your food to keep track of the number of servings you eat.

On some food products, the Nutrition Facts label may have two columns. One column shows information for a single serving. The other column shows information for the entire package.


The next information on the nutrition label is the amount of calories per serving. A calorie is a measurement of energy. Calorie information can help you manage your weight if you need to gain, lose, or maintain.

 The Nutrition Facts label is based on a 2,000 calorie diet. Your calorie needs may be more or less. People in cancer treatment may need to consume more calories to give their body the energy it needs to recover from treatment.

The amount of calories a person needs each day depends on a lot of factors including

  • Sex
  • Age
  • Physical activity level
  • Nutritional needs
  • Whether the person aims to lose, maintain, or gain weight

Ask your doctor or a registered dietitian for a daily calorie goal based on your needs.

Calories are not the only important information on the Nutrition Facts label. Many people consume more calories than they need without meeting the recommended amounts of important nutrients. A food that is low in calories but also low in nutrients may still not be a good food choice. A food that is high in calories may still be a good food choice if it is also high in the nutrients your body needs.

Nutrients and % Daily Value 

Based on a 2,000 calorie-per-day diet, the % Daily Value tells you the percentage of the recommended daily intake for each nutrient. For example, a food with 5% of the Daily Value of fiber provides 5% of the total fiber that a person consuming 2,000 calories a day should eat each day.

Your calorie needs may be more or less than 2,000 calories per day. The amount you need of a specific nutrient may be more or less than the recommended Daily Value. Ask your doctor or a registered dietitian for guidance.

Even if your nutritional needs are different, you can still use the % Daily Value to determine if a serving of a food is high or low in a nutrient.

A low % Daily Value is 5 percent or less. Choose foods that are low in saturated fat, Trans fat, cholesterol, added sugar and sodium. Aim to eat less than 100% of the Daily Value for these nutrients each day.

A high % Daily Value is 20 percent or more. Choose foods that are high in dietary fiber, vitamin D, calcium, iron, and potassium. Aim to eat 100% Daily Value or more of these nutrients each day.

Nutrients without % Daily Value 

Trans fat and total sugars do not list a % Daily Value on the label because there are no recommendations for the amount to eat per day.

Aim to keep your intake of trans fat as low as possible. Trans fat is linked to increased risk of heart disease. Examples of foods that may contain trans fat includes baked goods, chips, fried foods, creamer, and margarine.

Aim to keep your daily intake of added sugar below 25 grams for women and below 37 grams for men. Added sugars are sugars added during preparation or processing, or are packaged as such (e.g. table sugar). Examples of foods that contain added sugar include sugars from syrups and honey, sugar sweetened beverages, candy, cookies, pies, dairy desserts, milk products, and sugar sweetened cereals.

For protein, a % Daily Value is only required to be listed if the food claims to be high in protein. How much protein do you need each day? Divide your ideal weight by 2 to determine the minimum grams of protein your body needs daily. Cancer patients may need to increase their protein intake. Ask your doctor or a registered dietitian for a recommendation.
