Reading food labels will help you know if a food is a
healthy choice. The food label is a reliable source of
valuable nutrition information. Reading and comparing food
labels will help you limit nutrients that you want to cut
back on and increase nutrients that are good for you. It
will also help you avoid ingredients that you may be
sensitive to.
What do terms such as fortified and low-fat mean?
Food packages often have labels that point out a nutritional
value, such as "low in fat and cholesterol" or "fortified
with iron." By law, companies can use these terms only if
the food meets specific requirements. Here are the
requirements for these terms:
- Fat-free means the food has less than a half gram of fat
per serving.
- Low-fat means less than 3 grams (g) of fat per serving.
- Cholesterol free means less than 2 milligrams (mg) of
cholesterol per serving.
- Low cholesterol means less than 20 mg of cholesterol and
2 g or less of saturated fat per serving.
- Low sodium means less than 140 mg of salt per serving.
- Low calorie means less than 40 calories per serving.
- Sugar-free means less than a half gram of sugar per
serving.
- Fortified means the food provides more than 10% of the
daily requirement for the nutrient the food is fortified
with.
- High or rich means the food contains 20% or more of the
daily value for a specific nutrient. (See the section on
using the nutrition label for more about the daily
value.)
What are functional foods?
Functional foods are foods, or substances in foods, that may
provide health benefits beyond basic nutrition. It is well
known that some foods provide specific health benefits.
Examples include soluble fiber, which decreases cholesterol,
and calcium-rich foods, such as dairy, which help prevent
bone loss. Functional benefits of many traditional foods
are still being discovered, and new food products are being
developed that contain beneficial ingredients. For example,
some margarines are being made with plant stanols and
sterols, which have been shown to decrease cholesterol
levels.
Sometimes you will see a health claim made on a package,
such as "Diets low in saturated fat, cholesterol, and total
fat may reduce the risk of coronary heart disease." These
claims are a way of letting you know about the additional
health benefits of functional foods. The Food and Drug
Administration (FDA) has approved claims for 12 diet and
health relationships. These approved claims are supported
by extensive research. Recently the FDA has also made it
possible for food labels to make qualified health claims
based on very strong, but not absolutely proven
relationships between some foods and health. For example,
foods that are high in potassium and low in sodium and
saturated fat may reduce the risk of high blood pressure and
stroke.
How do I read the ingredients list?
Food packages should list the ingredients somewhere on the
package. The ingredients are listed in descending order by
weight. They include any nutrients, color additives,
preservatives, fats, or sugars that have been added. This
is helpful information if you have allergies and can't eat
some foods or additives.
How do I use the Nutrition Facts label?
Almost all foods in grocery stores have the
government-required Nutrition Facts label, which can be found on the
side or back of the package. (Very small packages, foods
made in the store, and foods made by small manufacturers do
not have to include this label.) The Nutrition Facts label
helps you make healthy choices for your diet. It can also
help you compare one brand of food with another.
Most of the information on the Nutrition Facts label is
based on a 2000-calorie-a-day diet. The recommended daily
calories for you may be higher or lower, depending on your
age, gender, and how active you are. For example, inactive
or older people usually burn just 1600 calories a day.
Active people and teenagers burn up to 2800 calories or
more a day. Keep this in mind when you read the label. You
may need more or less of certain nutrients than the package
label shows. The footnote at the bottom of the label shows
the number of total grams of certain nutrients you need for
a 2000-calorie-a-day diet and sometimes also for a
2500-calorie-a- day diet.
Serving Size: At the top of the nutrition label is the serving
size and number of servings in the food package. The serving
size is usually less than most people eat. If you eat 2
servings, you will get twice as many calories and twice the
daily values listed on the nutrition label. If you are
comparing 2 foods side by side, check to see if the serving
sizes are the same.
Calories: The number of calories per serving is listed after
the serving size information. Calories are the measure of
how much energy you get from a serving of a food. Many
Americans take in more calories than they use for energy.
And they often get their calories from foods that have a lot
of calories and but not much nutrition. The calorie section
of the label can help you manage your weight. A general
guide to calories is 40 calories in a serving is low, 100
calories is moderate, and 400 calories or more is high.
This guide, again, is based on a 2000-calorie-a-day diet.
Calories from Fat: The label lists the number of calories
that come from fat in a serving of the food. The general
rule is that less than a third of your daily calories should
come from fat. If the food has 200 calories and 100
calories are from fat, the food is high in fat.
% Daily Value (% DV): The food label also shows the
percentage of the recommended daily amounts of a nutrient
you will get from 1 serving. A general rule of thumb for %
DV is: Less than 5% is low and over 20% is high. It is a
good idea to read the labels and choose foods that are low
in the following nutrients:
- Fat: The label lists the total amount of fat (in grams)
in 1 serving. There are different types of fats.
Saturated fats and trans fats are bad for you because
they raise your cholesterol level. They are often found
in foods such as butter, margarine, cheese, cookies,
salty snack foods, and whole-milk dairy products.
Monounsaturated and polyunsaturated fats, found in
vegetables, soybeans, nuts, seeds and fish, are healthy
in moderation. All fats are high in calories.
- Cholesterol: Too much cholesterol can lead to heart
disease and stroke. Try to eat less than 300 mg each
day.
- Sodium: Most of the sodium (salt) in your diet is hidden
inside foods rather than in the salt you add at the
table. Try to eat less than 2300 mg each day.
You will notice that some of the nutrients (sugar, protein
and trans fat) do not have a % DV. In such cases, you can
compare the amounts of these nutrients with the amounts in
other similar products to see which is the healthiest. For
sugar and trans fat, choose the product with the lowest
amount.
The nutrition label also lists other important nutrients.
- Carbohydrates: Carbohydrates help give you energy. They
are found in bread, pasta, potatoes, fruits, and
vegetables. This measure is especially useful to people
with diabetes or to others watching the amount of
carbohydrates in their diet. There are different types
of carbohydrates, including dietary fibers, sugars, and
starches.
- Sugars: Sugar occurs naturally in many foods, such as
fruits. It is also added to many foods (such as
cookies and snacks). Check the ingredients label for
sugar content. Snack foods are often high in sugar
content.
- Fiber: Dietary fiber is listed as part of the total
carbohydrate. Fiber provides very few or no calories,
but it is an important part of a healthy diet. Eating
fiber can help lower your risk of heart disease, keep
your bowel movements regular, and lower your
cholesterol level. Good sources of fiber include
fruits, vegetables, whole grains, peas, and beans.
Try to eat at least 20 g to 35 g of fiber per day.
- Protein: Protein helps build muscle. It is found in
meat, nuts, eggs, dairy products, fish, and dry beans.
Choose lean cuts of meat and nonfat or low-fat dairy
products to get protein without a lot of saturated fat.
Your body cannot store protein the way that it can store
fat, but most Americans have no problem getting enough
protein from the food they eat each day. Eating too much
protein can cause health problems for some people. Make
sure to eat protein as a part of a well-balanced diet
every day along with other nutrients.
- Vitamins and Minerals: Vitamins and minerals are a very
important part of a healthy diet. Vitamin A helps your
eyesight and skin. Vitamin C helps you fight infections
and heal wounds. Calcium is important for building bones
and teeth. Iron helps your red blood cells carry oxygen.
The food label lists the percentage of the recommended
daily amounts of these nutrients that you will get from 1
serving. Other nutrients may also be listed. For most
people, the goal is to reach 100% for each vitamin and
mineral every day. For example, if an orange juice label
says that 1 serving has 80% of the DV for Vitamin C, then
you need 20% more to fulfill your Vitamin C need for the
day. It is important to remember that in some cases you
may need more than 100% of some nutrients. For example,
teens need 1300 mg of calcium a day, which means they
need 130% of the DV.
Eating a variety of foods everyday is the key to good
health. In today's world where frozen dinners and packaged
foods are commonplace, food labels can go a long way in
helping you compare similar foods and make the healthiest
choices.
