How To Read A Label

If you are having some difficulty in understanding what each category means on a food label, use this post to help clarify your questions.

Serving Size
The nutrition label always lists a serving size, which is an amount of food, such as 1 cup of cereal, two cookies, or five pretzels. The nutrition label tells you how many nutrients are in that amount of food. Serving sizes also help people understand how much they're eating. If you ate 10 pretzels, that would be two servings.
Servings per Container or Package
The label also tells you how many servings are contained in that package of food. If there are 15 servings in a box of cookies and each serving is 2 cookies, then you have enough for all 30 kids in your class to have one cookie each. Math comes in handy with food labels!
Calories and Calories From Fat
The number of calories in a single serving of the food is listed on the left of the label. This number tells you the amount of energy in the food. People pay attention to calories because if you eat more calories than your body uses, you might gain weight.
Another important part of the label is the number of calories that come from fat. People check this because it's good to limit fat intake. The calories in a food can come from fat, protein, or carbohydrate.
Percent Daily Value
You'll see percentages on food labels that are based on recommended daily allowances - meaning the amount of something a person should get each day. For instance, there's a recommended daily allowance for fat, so the food label might say that one serving of this food meets 10% of the daily value. The daily values are based on an adult's needs, not a kids' needs. These are often similar, but kids need may need more or less of certain nutrients, depending on their age and size. Some percent daily values are based on the amount of calories and energy a person needs. These include carbohydrates, proteins, and fat. Other percent daily values - like those for sodium, potassium, vitamins, and minerals - stay the same no matter how many calories a person eats.
Total Fat
The total fat is the number of fat grams contained in one serving of the food. Fat is an important nutrient that your body uses for growth and development, but you don't want to eat too much. The different kinds of fat, such as saturated, unsaturated, and trans fat, will be listed separately on the label.
Cholesterol and Sodium
These numbers tell you how much cholesterol and sodium (salt) are in a single serving of the food. They are included on the label because some people need to limit cholesterol or salt in their diets. Cholesterol and sodium are usually measured in milligrams.
Total Carbohydrate
This number tells you how many carbohydrate grams are in one serving of food. Carbohydrates are your body's primary source of energy. This total is broken down into grams of sugar and grams of dietary fiber.
This number tells you how much protein you get from a single serving of the food. Your body needs protein to build and repair essential parts of the body, such as muscles, blood, and organs. Protein is often measured in grams.
Vitamin A and Vitamin C
These list the amounts of vitamin A and vitamin C, two especially important vitamins, in a serving of the food. Each amount is given as a percent daily value. If a food provides 20% of the RDA for vitamin A, that one serving of food gives an adult one fifth of the vitamin A needed for the day.
Calcium and Iron
These list the percentages of calcium and iron, two especially important minerals, that are in a serving of the food. Again, each amount is given as a percent daily value. If a food has 4% of iron, you're getting 4% of the iron you need for the whole day from that serving.
