背景知识
I．Healthy Eating for Lifetime
Variety, Balance and Moderation
A
healthy diet includes all foods. Variety is
important because no one food can
provide all
the nutrients the body needs for health. Try new
foods to tantalize your
taste and vary your
nutrient intake.
We can make many possible
choices within each food group. Choices may be
made to accentuate specific needs like fiber.
For example, in the protein-rich ‘meat’
group,
beans are a low fat, high fiber option compared to
ground beef. In the fruit
group, whole fruit
is usually a higher fiber choice than fruit juice.
Foods containing important
nutrients can help us prevent disease and even
restore
our health. Striking a balance between
foods that promote health and those that may
be risky is important for long term well
being. Choose foods that are better for your
health more often.
Without a doubt, fats
and cholesterol are the single most important
group of
nutrients to limit in your diet if
you want to reduce your risk of chronic disease.
Heart
disease and cancer, two of this nation’s
leading killers, are linked to diets high in fat.
Other chronic health problems may be
exacerbated by high fat diets. Saturated fat,
that is, fat that is solid at room
temperature, appears to carry the greatest amount
of
risk.
Alcohol is not pictured on the
food pyramid, but if it were it would be in the
tip of
the pyramid. Alcohol has only empty
calories in the way that sugar and most fats do.
Pregnant women should avoid alcohol beverages.
Foods and beverages that are less nutritious
do not have to be eliminated but they
should
be consumed in moderation - saved for special
occasions. Making healthy food
choices can be
the difference between health and disease.
II.
10 Tips to Healthy Eating
Experts agree the
key to healthy eating is the time-tested advice of
balance,
variety and moderation. In short,
that means eating a wide variety of foods without
getting too many calories or too much of any
one nutrient. These 10 tips can help you
follow that advice while still enjoying the
foods you eat.
1. Eat a variety of nutrient-
rich foods. You need more than 40 different
nutrients for
good health, and no single food
supplies them all. Your daily food selection
should
include bread and other whole-grain
products, fruits, vegetables, dairy product and
meat, poultry, fish and other protein foods.
How much you should eat depends on
your
calorie needs. Use the Food Guide Pyramid and the
Nutrition Facts panel on
food labels as handy
references.
2. Enjoy plenty of whole grains,
fruits and vegetables. Surveys show most Americans
don’t eat enough of these foods. Do you eat
6-11 servings from the bread, rice, cereal
and
pasta group, 3 of which should be whole grains? Do
you eat 2-4 servings of fruit
and
3-5 servings of vegetables? If you don’t enjoy
some of these at first, give them
another
chance. Look through cookbooks for tasty ways to
prepare unfamiliar foods.
3. Maintain a
healthy weight. The weight that’s right for you
depends on many factors
including your sex,
height, age and heredity. Excess body fat
increases your chances
for high blood
pressure, heart disease, stroke, diabetes, some
types of cancer and other
illnesses. But being
too thin can increase your risk for osteoporosis,
menstrual
irregularities and other health
problems. If you’re constantly losing and
regaining
weight, a registered dietitian can
help you develop sensible eating habits for
successful weight management. Regular exercise
is also important to maintaining a
healthy
weight.
4. Eat moderate portions. If you keep
portion sizes reasonable, it’s easier to eat the
foods you want and stay healthy. Did you know
the recommended serving of cooked
meat is 3
ounces, similar in size to a deck of playing
cards? A medium piece of fruit is
1 serving
and a cup of pasta equals 2 servings. A pint of
ice-cream contains 4 servings.
Refer to the
Food Guide Pyramid for information on recommended
serving sizes.
5. Eat regular meals. Skipping
meals can lead to out-of-control hunger, often
resulting
in overeating. When you’re very
hungry, it’s also tempting to forget about good
nutrition. Snacking between meals can help
curb hunger, but don’t eat so much that
your
snack becomes an entire meal.
6. Reduce, don’t
eliminate certain foods. Most people eat for
pleasure as well as
nutrition. If your
favorite foods are high in fat, salt or sugar, the
key is moderating
how much of these foods you
eat and how often you eat them.
Identify major
sources of these ingredients in your diet and make
changes if necessary.
Adults who eat high-fat
meats or whole-milk dairy products at every meal
are
probably eating too much fat. Use the
Nutrition Facts panel on the food label to help
balance your choices.
Choosing skim or
low-fat dairy products and lean cuts of meat such
as flank steak and
beef round can reduce fat
intake significantly.
If you love fried
chicken, however, you don’t have to give it up.
Just eat it less of ten.
When dining out,
share it with a friend, ask for a take-home bag or
a smaller portion.
7. Balance your
food choices overtime. Not every food has to be
“perfect”. When
eating a food high in fat,
salt or sugar, select other foods that are low in
these
ingredients. If you miss out on any food
group one day, make up for it the next. Your
food choices over several days should fit
together into a healthy pattern.
8. Know your
diet pitfalls. To improve your eating habits, you
first have to know
what’s wrong with them.
Write down everything you eat for three days. Then
check
your list according to the rest of these
tips. Do you add a lot of butter, creamy sauces
or salad dressings? Rather than eliminating
these foods, just cut back your portions.
Are
you getting enough fruits and vegetables? If not,
you may be missing out on vital
nutrients.
9. Make changes gradually. Just as there are
no “super foods” or easy answers to a
healthy
diet, don’t expect to totally revamp your eating
habits overnight. Changing
too much, too fast
can get in the way of success. Begin to remedy
excesses or
deficiencies with modest changes
that can add up to positive, lifelong eating
habits.
For instance, if you don’t like the
taste of skim milk, try low-fat. Eventually you
may
find you slimming, too.
10. Remember,
foods are not good or bad. Select foods based on
your total eating
patterns, not whether any
individual food is “good” or “bad.” Don’t feel
guilty if you
love foods such as apple pie,
potato chips, candy bars or ice-cream. Eat them in
moderation, and choose other foods to provide
the balance and variety that are vital to
good
health.
Figuring Out Fat
With so much
information available about the effects of dietary
fat on health,
understanding the role fat
plays in a well-balanced diet can be pretty
confusing. To cut
through the confusion, it’s
important to remember that fat is an essential
nutrient that
everyone needs to stay healthy.
Fat is a valuable energy source and carries
fat-soluble vitamins needed for proper
growth
and development. It also contributes important
taste and textural qualities that
are part of
enjoying food.
Too much fat, however, can
increase the risk of heart disease, obesity and
other
health problems. When
moderating fat intake, it’s important to consider
these points:
●Health authorities recommend
Americans to consume 30 percent or less of their
total
daily calories from fat, with 10 percent
or less of those calories from saturated fat.
Remember, the 30 percent refers to your total
fat intake overtime, not single foods or
meals. Use the following chart to guide your
fat intake.
If you eat this number of Total
fat per day (grams)
calories per day:
1,600
2,000
2,200
2,500
53 or
less
65 or less
73 or less
80 or less
Total saturated fat per day
(grams)
18
or less
20 or less
24 or less
25 or
less
●Use the Nutrition Facts panel on the
food label to help determine how much fat is in
foods. Remember, it’s the total fat intake
overtime that’s important. A food high in fat
can be part of a healthy diet as long as it’s
balanced with other lower-fat food choices.
●All fats are a combination of saturated,
polyunsaturated and monounsaturated fatty
acids. Each of these types of fats have
different effects on the body, but all contain
nine calories per gram.
●Blood cholesterol
levels are influenced by family history, weight,
age, smoking,
physical activity and eating
habits. Studies have shown that diets which are
too high
in certain saturated fatty acids and
dietary cholesterol can raise blood cholesterol.
III. Healthy Eating for Lifetime
The Food
Guide Pyramid
The Food Guide Pyramid is
a visual
tool making it easy to see how many
servings we need to eat from each food
group each day. Within its six food
groups, the Pyramid contains many
kinds of
health promoting foods. All
foods
can fit into a healthy eating style.
The
Pyramid base, the largest area, is filled with
grains. Building our diets around
grains,
especially whole grains, is what the food guide
pyramid promotes. Eating the
suggested
portions from this food group will assure that
more than half of our calories
comes from
complex carbohydrates. Moving up the Pyramid,
notice the groups get
smaller. Foods
represented in these groups are needed in smaller
amounts for good
health. The tip of the
Pyramid is the smallest group and should be eaten
from the least:
oils, fats and sweets.
The Food Guide Pyramid is available in different
languages representing various
cultures and
eating styles. There are variations for young
children (Adobe .PDF
format) and for seniors.
There are also pyramids to help you with special
eating
plans——such as diabetic or vegetarian.
How many servings do I need each day?
The
number of servings needed each day depends on age,
gender and activity level.
This shows the
range of appropriate servings:
Grains
Vegetables
Fruits
Dairy
Protein
6-11 servings
3-5 servings
2-4
servings
2-3 servings
2-3 servings
What are some examples of adult serving sizes?
Grains 1 slice bread, 12 small bagel, about 1
cup
ready to eat cereal flakes, 12 cup cooked
cereal, rice or pasta
Vegetables 1 cup raw
leafy greens, 12 cup other
vegetables——raw or
cooked, 34 cup
vegetable juice
Fruits 1
medium apple, banana, orange, pear,
12 cup
chopped, cooked or canned fruit,
14 dried fruit like raisins, 34cup 100%
fruit juice
Milk, Yogurt, Cheese 1 cup
milk or yogurt, 12 ounce natural or
2 ounces
processed cheese, 1 cup soy
beverage with
added calcium
Meat, Poultry, Fish, Dried
Beans, Eggs 2-3 ounces of cooked lean meat,
poultry
and Nuts or fish, 1 cup cooked dry
beans or tofu
counts as 2 ounce of lean meat,
12 ounce
soy burger or 1 egg counts as 1 ounce
lean meat, 2 tablespoons of peanut butter
or 13 cup nuts counts as 1 ounce of meat
IV． Tips On How To Make Healthier Meals
Begin by choosing foods low in saturated fat,
low in sodium and low in calories:
●Try fat
free (skim) milk or low fat (1%) milk
●Only
buy cheeses marked “low fat” or “fat free” on the
package
●Choose to eat fruits and vegetables
without butter or sauce
●Serve rice, beans,
cereals, pasta, whole grains (e.g., couscous,
barley, bulgar, etc.)
●Choose lean cuts of
meat, fish, and skinless turkey and chicken
●When available, buy low- or reduced-sodium or
no-salt-added versions of foods
Use these
recipe substitutions:
●Use two egg whites for
each whole egg and
