You know how books have a table of contents that explains what's inside? Or maybe
you have a toy that came with a diagram that identified each small piece.
Nutrition labels are sort of like that. They tell you what's inside the food you're
eating and list its parts.
Get Your Nutrition Facts Straight
The Nutrition Facts food label gives you information about which nutrients
(say: NEW-tree-ents) are in the food. Your body needs the right combination of nutrients,
such as vitamins, to work properly
The Nutrition Facts food label is printed somewhere on the outside of packaged
food, and you usually don't have to look hard to find it. Fresh food that doesn't
come prepackaged sometimes has nutrition facts, too.
Most nutrients are measured in grams, also written as g.
Some nutrients are measured in milligrams, or mg.
Milligrams are very tiny — there are 1,000 milligrams in 1 gram.
Other information on the label is given in percentages. Food contains
fat, protein, carbohydrates, and fiber. Food also contains vitamins, such as A and
C, and minerals, such as calcium and iron. Nutrition specialists know how much of
each one kids and adults should get every day to have a healthy diet. The percent
daily value on a food label tells you how this food can help someone meet these daily
On food labels, they base the percentages on a 2,000-calorie adult diet. So looking
at the label above for two crackers, a grownup would see that they provide less than
1 gram of fiber, only 3% of the person's daily needs. So that means he or she would
have to eat other foods to get 100% of the fiber needed each day. Similarly, the person
would see that the crackers provide nothing toward the daily goals for vitamin A,
vitamin C, calcium, or iron.
Food labels aren't ideal for kids because they're calculated based on what adults
need to eat. A kid's diet might be more or less than 2,000 calories, based on your
age, whether you are a boy or girl, and how active your are. Likewise, kids may need
more or less of certain food components and nutrients, such as calcium and iron.
But kids can still get important information from food labels. They can get a general
idea about what the food contains, how much is in a serving, and how many calories
are in a serving.
Kids also can use labels to compare two foods. Which one has more fiber? Which
one has more fat? Which one has more calories per serving?
The ingredient list is another important part of the label. Ingredients are listed
in order so you get an idea of how much of each ingredient is in the food. When something
is listed first, second, or third, you know that this food probably contains a lot
of it. The food will contain smaller amounts of the ingredients mentioned at the end
of the list.
With that in mind, check ingredient lists to see where sugar appears. Limit foods
that mention sugar in the first few ingredients. That means it's a very sugary food.
Sugar has different names, so it might also be called high fructose corn syrup, corn
syrup, sucrose, or glucose.
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 two cookies, 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. The calories in
a food can come from fat, protein, or carbohydrate. People pay attention to calories
because if you eat more calories than your body uses, you will 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 to about 30% or less of the
calories they eat.
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 should limit the amount of cholesterol and salt in their diets.
Cholesterol and sodium are usually measured in milligrams.
This number tells you how many carbohydrate
grams are in one serving of food. Carbohydrates are your body's primary source of
energy. Under this heading, the number of grams of sugar and grams of dietary fiber
in each serving are listed.
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
Vitamin A and Vitamin C
These list the amounts of vitamin A and vitamin C, two important vitamins, in a
serving of the food. Each amount is given as a percent daily value. Other vitamins
may be listed on some labels.
Calcium and Iron
These list the percentages of calcium
and iron, two important minerals, that are in a serving of the food. Again, each
amount is given as a percent daily value and other minerals may be listed on the label.
Calories per Gram
These numbers show how many calories are in one gram of fat, carbohydrate, and
protein. This information is the same for every food and is printed on the food label
