Pyramid Diet
Learn how the new prebiotic soluble fibers benefit bowel health and many GI disorders
Purpose
A healthy diet plays a major role in keeping the body fit and
preventing illness. Based on medical research, a regular diet has
been developed that arranges food groups into a food guide pyramid.
This pyramid symbol makes it easy for individuals to choose what to
eat, how much to eat, and how to avoid harmful excesses like too much
fat, cholesterol, sugar, sodium, and alcohol.
Nutrition
Scientists have identified more than 40 nutrients -- proteins,
vitamins, minerals, and fiber -- that the body needs for energy and
good health. Based on this information, the National Research Council
has established the Recommended Dietary Allowance (RDA) of nutrients
required for good health. These nutrients should come from a variety
of foods, not from just a few highly fortified foods or supplements.
Following the pyramid diet provides the RDA for healthy people two
years of age and over. This diet is not for people who need special
diets designed for certain medical conditions.
The Pyramid
The pyramid is a symbol of stability, good design and structure. It
contains a large sturdy base upon which to build. Each level of the
pyramid then supports the smaller level above it. Except for the
peak, all levels must remain intact to preserve the integrity of the
structure. This is exactly how a healthy diet should be designed (see
pyramid on back cover). The food groups are arranged on the pyramid
according to the number of servings required from each to construct a
healthy diet. For example, the largest number of servings each day
should come from the bottom level, the bread or grain group. A
smaller number of fruit and vegetable servings are required, so those
groups are on the next level, and so on. However, no one food group
is more important than another. A variety of foods from all levels is
needed each day for good health. Of course, much of the peak may be
removed without affecting the stability of the diet.
Base Level
Breads, cereals, rice, and pasta come from grains. They provide the
body's largest portion of energy. Six to eleven servings should come
from this group each day. These grain foods also contain fiber (the
indigestible part of plants). There are two types or fiber, and both
are needed for good health. Insoluble fiber, such as wheat bran, does
not dissolve in water, so it helps the body to regulate bowel
function by adding bulk. Soluble fiber is the type found in many
fruits. It does dissolve in water and forms a sticky gel in the
digestive tract. This soluble fiber gel probably helps to reduce
cholesterol levels by binding with it and sweeping it out of the
intestines. There is also evidence that increasing fiber in the diet
reduces the risk of developing certain cancers. This is why it is
recommended that people eat 20 to 30 grams of fiber a day, which
should include both soluble and insoluble fibers.
Choose foods from the grain group that are low in fats and sugars
-- breads, English muffins, bagels, rice, or pasta. Avoid cakes,
cookies, croissants, or pastries. These are usually made with
processed flours (grains that have had the fiber removed), and they
contain large amounts of fat and sugar. Also, avoid placing cream or
cheese sauces on pasta and rice because they add fat calories.
Level Two
Fruits and vegetables are together on this level because they are low
in fat and provide vitamins, minerals, and fiber. Because different
fruits and vegetables provide different nutrients, a variety should
be chosen throughout the day. Be sure to have two to four servings of
fruit and slightly more servings of vegetables (three to five) each
day.
Citrus fruits, melons, and berries are especially rich in vitamin
C. Whole fresh fruits contain much less sugar than those canned or
frozen in heavy syrup. Whole fruits contain more fiber than is found
in fruit juice, but if choosing fruit juice, make sure it is 100%
fruit juice. Grape and orange sodas are not fruit juice. Punches and
fruit "drinks" contain only a little fruit juice and a large amount
of added sugar.
Choose a wide variety of vegetables to get a balance of the
nutrients they provide. Select dark green leafy vegetables over light
green. Romaine lettuce, for example, has about six times as much
vitamin C and eight times as much beta carotene as iceberg lettuce.
Legumes (peas and beans) are good sources of fiber and provide lowfat
protein that can be used in place of meat. Eat vegetables raw when
possible; however cooked vegetables are also nutritious. It is how
they are cooked that is important. To maintain eye and taste appeal
and to preserve nutrients, do not over-cook. Sometimes the method of
preparation helps to preserve or enhance nutrients. For example,
vitamin C-rich vegetables lose half of the vitamin when boiled, but
only 15% when microwaved. Remember, variety is the key.
Level Three
The Milk, Yogurt, and Cheese Group and the Meat, Fish, Poultry, Eggs,
and Dry Beans Group are good sources of protein, calcium, iron, and
zinc. These nutrients are required for growth and normal development
of the body. Whole Milk, yogurt, and cheese are the best sources of
calcium, but they can also be high in fat. Aged or natural cheeses
and ice cream can be very high in fat. Choose lowfat varieties such
as skim or 1% fat milk, lowfat yogurt, "part skim" or lowfat cheeses,
and ice milk or frozen yogurt. Most people should have at least two
servings a day from this group. However, teenagers, young adults
under 25, women who are pregnant or breast-feeding, and
post-menopausal women should have 3 servings each day.
Choose two to three servings a day of meat, poultry, fish, or
alternatives (dry beans, eggs, or nuts). Choose lean cuts of meat,
and trim away visible fat and skin. Broil, roast, or bake instead of
pan frying. Three ounces of cooked meat, poultry, or fish is about
the size of a deck of cards. One-half cup of cooked dry beans, 1 egg,
or 2 tablespoons of peanut butter equals one ounce of meat. Dry beans
are an excellent alternative to meat because they are a good source
of high quality protein, are low in fat and high in fiber. Go easy on
eggs because they are high in cholesterol. Use only one yolk per
person in egg dishes, and substitute egg whites if more eggs are
called for. Nuts and seeds are good sources of calcium and zinc, but
they are high in fat and should be eaten in moderation.
Observe the 3/4 plate rule to help control portion sizes, cut down
on fat, and get the proper mix of nutrients. This means that 3/4 of
the dinner plate should be filled with grains, vegetables, legumes,
and fruit. Only 1/4 should be meat, fish, or chicken.
The Peak of the Pyramid
Added fats, oils, and concentrated sweets form the peak of the
pyramid. If they were eliminated, the remaining choices would still
form a completely nutritious diet. Fats and oils are represented by
the symbol l, and sugars by the symbol t (see pyramid on back cover).
While the majority of these symbols
are located within the peak, a few are scattered throughout the
other layers of the pyramid. This is because some choices in the
other food groups naturally contain fat and/or sugars. Keep this
important fact in mind -- that up to half the amount of fat eaten
during the day will come from the other food groups, even when lowfat
choices are made.

Special
Considerations
|
- Fats: A certain amount of fat is needed in a healthy
diet to supply energy and a few nutrients. However, fats
are a high calorie source of energy, and too much fat in
the diet can increase the risk of heart disease and
certain cancers. Fat is measured in grams. One teaspoon
of fat equals four grams. There are different kinds of
fat in foods, and some types are worse than others.
- Saturated fats are found in dairy products made
with whole milk and in meat. Some meats contain a
greater quantity of saturated fats than others: beef
more than chicken. Saturated fats are solid at room
temperature. Some vegetable fats such as coconut,
cocoa butter (found in chocolate), palm and palm
kernel oils are also saturated. Eating too much
saturated fat raises blood cholesterol, increasing the
risk of heart disease.
- Unsaturated fats, found mostly in plants, are
liquid at room temperature. Polyunsaturated fats are
found in safflower, sunflower, corn, soybean, and
cottonseed oils, and in some fish. Unsaturated fats
are less likely to cause heart disease. In fact,
monounsaturated fats, found in olive, peanut, and
canola oils, appear to lower cholesterol.
- Hydrogenated oils is a term often found in food
labels. Through a manufacturing process, normally
liquid vegetable oils can be made to stay solid at
room temperature. Therefore, they act as saturated
fats and should be avoided in the diet.
- Avoid using saturated fats, margarines, gravies,
and high fat salad dressings in preparing naturally
lowfat foods. For example, one baked potato has 120
calories and only a trace of fat, but the same potato
made into french fries has 225 calories and 11 grams
of fat!
- The number of fat grams allowed per day depends on
a person's caloric requirements. Fat intake should be
limited to approximately 30% of daily calories.
Saturated fat should be limited to 10% of daily
calories, or about 1/3 of the total fat intake.
Remember that about half of this fat will come from
other food groups, and this should be included when
calculating the total fat intake. Determine the number
of calories needed each day, and then use the chart
below as a guide to determine the number of fat grams
permitted.
- Those people who like to do their own math can
determine their fat intake requirements by using the
following formula.
- Multiply the total day's calories by
0.30 to get calories from fat per day.
Example: 2200 calories x 0.30 = 660
calories from fat.
- Each gram of fat has nine calories, so divide
the calories from fat per day by 9 to get grams of
fat permitted each day.
Example: 660 calories from fat ÷ 9 =
73 grams of fat allowed per day.
- If the total fat intake on this diet is 73
grams for the day, no more than 24 grams (about
one-third of the total fat intake) should be in
saturated fats.
- What About Cholesterol? This waxy, fat-like substance
is needed for important functions in the body. As is
often the case, however, too much of a good thing can be
bad. Too much cholesterol in the blood can increase the
risk of heart disease. Where does cholesterol come from?
Foods from animal sources contain cholesterol because
animals produce cholesterol in their bodies. The human
body also makes its own cholesterol. In fact, it produces
all that it needs, and doesn't require any from the diet.
That is why many health authorities recommend limiting
foods from animal sources in the diet. Some animal foods
are higher in cholesterol than others: egg yolks and
organ meats such as liver or sweetbreads, for example. It
is recommended that dietary cholesterol be limited to an
average of 300 milligrams (mg) or less a day. It is not
necessary to stop eating high cholesterol foods
completely. Balance is the key; if high cholesterol foods
are eaten one day, eat low cholesterol foods the next.
Three to four egg yolks a week are generally permissible,
including those used in preparing foods such as baked
goods and custards. Remember that foods from plants do
not contain cholesterol.
- Sugars: Choosing a diet low in sugar is important.
Sugars found naturally in fruits and milk are not a
problem. It is the adding of sugar to foods in
processing, preparing, or at the table that increases
calories without providing nutrients. Sugars include
white sugar, brown sugar, raw sugar, corn syrup, honey,
and molasses. Foods like soft drinks, candy, ice cream,
jams, jellies, chocolate milk, and fruits canned in heavy
syrups are high in sugar and should by limited in the
diet. Use the guide below to avoid getting too many
calories from added sugar.
- Salt and sodium: Most people eat more of it than they
need. Sodium is an essential element for the body, but
eating too much of it can cause health problems. Sodium
is found naturally in many foods, but much of the excess
in our diets comes from salt added while cooking, in food
processing, or at the table. Table salt is about one-half
sodium. One teaspoon of salt provides about 2000 mg of
sodium. Most health authorities say that sodium intake
should be less than 3000 mg a day, so it is important to
avoid adding too much salt to foods. Always check food
labels for sodium content. It is a good idea to purchase
foods with less than 300 mg of sodium per serving.
- Learn to read food labels. Federal regulations
require standardized labels on food packages to provide
reliable information and to help consumers make healthier
food choices. The regulations require full ingredient
listing and standardized serving sizes. Health claims and
descriptions such as "light" or "low fat" are required to
meet certain guidelines. Most packages on supermarket
shelves have labels that look like the one shown in
figure 1.
- Ingredients must be listed in order, by quantity,
from the largest to the smallest. For example, if a can
of soup contains more water than anything else, then
water is listed first. Certain nutrients are shown as a
percentage of Daily Value. These values were established
based on daily calorie requirements. Using an example
from this label, on a diet of 2000 calories per day, the
daily value of total fat (100%) should equal no more than
65 grams. A serving of this product contains 4 g of fat,
about 6% of the daily value.
- Always check the serving size. The values listed are
for one serving. This label lists the serving size as one
cup, with a total of two servings in the container. A
person eating the entire container would be getting 12%
of the daily value of fat.
- Drinking excessive alcohol is the cause of many
health problems. Some medical studies indicate that a
glass of red wine each day may produce benefits for the
cardiovascular system. However, if you are a non-drinker,
do not begin to use alcohol just for this uncertain
benefit. If you do drink alcoholic beverages, do so in
moderation. Alcohol adds calories, and little or no
nutrients.

How Does the Pyramid Work for Different Individuals?
A person eating the proper number of selections and a variety of
foods from each level of the pyramid will be getting the correct
proportions of carbohydrate, protein, and fat for a healthy diet.
Remember that fat in the diet should not equal more than 30% of total
calories. What about the other 70%?
All healthy adults need from 10% to 20% of the total daily
calories in protein. However, athletes may need slightly more during
periods of intense training. When more protein is eaten than the body
needs, the excess is stored as fat. When choosing protein foods,
remember that they do not have to come only from animal sources.
Certain vegetables and grains also contain protein and are lower in
saturated fats.
The remainder of the diet (50% to 60%) should come from
carbohydrates. A person eating less than 30% of calories from fat
should make up the difference in carbohydrates, not in proteins.
These ranges are meant as a guide and may vary depending on
individual requirements.
Notice that each food group on the pyramid shows a range of
servings. The number of servings needed per day depends on the number
of calories needed. A calorie is a unit of measure that explains how
much energy various foods supply to the body. The number of calories
needed to supply enough energy each day depends on a person's age,
gender, size, and activity level. Use figure 2 as a guide.
It is simple to adjust the pyramid diet for weight gain or weight
loss. To lose weight, obviously it is necessary to reduce food or
calorie intake. Reduce the number of servings in each food group by
one or more, being careful to maintain the balance. Do not go below
the lowest number of servings required per food group. If more weight
reduction is needed reduce fats and sugars further, and increase
physical activity. To gain weight, increase the number of servings
proportionately in all food groups.
For young children, the calorie requirements can vary. Some
preschool children need the same variety of foods as older family
members, but may need fewer than 1600 calories. In this case they can
simply eat smaller servings to maintain variety. A child's weight and
height are the best guides to follow. An overweight child is getting
too many calories. It is best to check with the child's physician to
determine individual requirements.
Women who are pregnant or breast-feeding may need more calories or
selections from certain food groups, and should consult their
physicians. Finally, for any questions or individual guidance on
using the food pyramid, check with a physician or a registered
dietitian.
