Dietary Guidelines
Environmed
Research Inc. Course Work; Supplement 1999
We recommend studying the US official guide to our students. We suggest
that they approach the guidelines as a theoretical structure and as advice to a population
of people with diverse needs and not to single individuals whose nutritional needs may not
be met by these recommendations and whose health may be at risk if they follow the food
selection advice. A skillful nutritional therapist will know the guidelines as one
way to organize food selection but will also know the many exceptions to these rules
and have other methods of diet design such as the
Alpha Nutrition Program
Revised US Guidelines - the Food Pyramid
The US 1995 Dietary Guidelines issued in 1995 presents an overview of
conventional nutritional thinking and much of the general advice offered is sound. The
food selection, however, should not considered anything more or less than local custom
steered by a local economy. We want to emphasize that there are millions of people whose
health may be at risk if they follow the food selection advice. In the 1990's official
dietary recommendations in the USA and Canada changed to a "food pyramid"
approach which gave more value to eating fruits, vegetables and grains, but retained dairy
products, cereal grains and meats as essential foods.
Harvard's Walter Willet reviewed the new recommendations and stated: " The dietary
pyramid released by the U.S. Department of Agriculture attempts to translate current
nutritional knowledge to a recommended eating pattern in terms of food groups. Inevitably,
such a document represents a mix of well-supported findings, educated guesses, and
political compromises with powerful economic interests such as the dairy and meat
industries."
Willet's conclusion is that "...optimal health can be achieved from a diet that
emphasizes a generous intake of vegetables and fruit. Such plant-enriched diets, as
embodied by other cultures can be not only healthy, but interesting and enjoyable as
well."

What should Americans eat to stay healthy?
These guidelines are designed to help answer this question. They
provide advice for healthy Americans age 2 years and over about food choices that promote
health and prevent disease. To meet the Dietary Guidelines for Americans, choose a diet
with most of the calories from grain products, vegetables, fruits, low fat milk products,
lean meats, fish, poultry, and dry beans. Choose fewer calories from fats and sweets.
Eating is one of life's greatest pleasures
Food choices depend on history, culture, and environment, as well
as on energy and nutrient needs. People also eat foods for enjoyment. Family, friends, and
beliefs play a major role in the ways people select foods and plan meals. This booklet
describes some of the many different and pleasurable ways to combine foods to make
healthful diets.
Diet is important to health at all stages of life
Many genetic, environmental, behavioral, and cultural factors can
affect health. Understanding family history of disease or risk factors -- body weight and
fat distribution, blood pressure, and blood cholesterol, for example -- can help people
make more informed decisions about actions that can improve health prospects. Food choices
are among the most pleasurable and effective of these actions. Healthful diets help
children grow, develop, and do well in school. They enable people of all ages to work
productively and feel their best. Food choices also can help to reduce the risk for
chronic diseases, such as heart disease, certain cancers, diabetes, stroke, and
osteoporosis, that are leading causes of death and disability among Americans. Good diets
can reduce major risk factors for chronic diseases -- factors such as obesity, high blood
pressure, and high blood cholesterol.
Foods contain energy, nutrients, and other components that affect health. People
require energy and certain other essential nutrients. These nutrients are essential
because the body cannot make them and must obtain them from food. Essential nutrients
include vitamins, minerals, certain amino acids, and certain fatty acids. Foods also
contain other components such as fiber that are important for health. Although each of
these food components has a specific function in the body, all of them together are
required for overall health. People need calcium to build and maintain strong bones, for
example, but many other nutrients also are involved. The carbohydrates, fats, and proteins
in food supply energy, which is measured in calories. Carbohydrates and proteins provide
about 4 calories per gram. Fat contributes more than twice as much -- about 9 calories per
gram. Alcohol, although not a nutrient, also supplies energy -- about 7 calories per gram.
Foods that are high in fat are also high in calories. However, many low-fat or nonfat
foods can also be high in calories.
Physical activity fosters a healthful diet
Calorie needs vary by age and level of activity. Many older
adults need less food, in part due to decreased activity, relative to younger, more active
individuals. People who are trying to lose weight and eating little food may need to
select more nutrient-dense foods in order to meet their nutrient needs in a satisfying
diet. Nearly all Americans need to be more active, because a sedentary lifestyle is
unhealthful. Increasing the calories spent in daily activities helps to maintain health
and allows people to eat a nutritious and enjoyable diet.
What is a healthful diet?
Healthful diets contain the amounts of essential nutrients and
calories needed to prevent nutritional deficiencies and excesses. Healthful diets also
provide the right balance of carbohydrate, fat, and protein to reduce risks for chronic
diseases, and are a part of a full and productive lifestyle. Such diets are obtained from
a variety of foods that are available, affordable, and enjoyable.
The Recommended Dietary Allowances refer to nutrients
Recommended Dietary Allowances (RDAs) represent the amounts of
nutrients that are adequate to meet the needs of most healthy people. Although people with
average nutrient requirements likely eat adequately at levels below the RDAs, diets that
meet RDAs are almost certain to ensure intake of enough essential nutrients by most
healthy people. The Dietary Guidelines describe food choices that will help you meet these
recommendations. Like the RDAs, the Dietary Guidelines apply to diets consumed over
several days and not to single meals or foods.
The Dietary Guidelines describe food choices that promote
health
The Dietary Guidelines are designed to help Americans choose
diets that will meet nutrient requirements, promote health, support active lives, and
reduce chronic disease risks. Research has shown that certain diets raise risks for
chronic diseases. Such diets are high in fat, saturated fat, cholesterol, and salt and
they contain more calories than the body uses. They are also low in grain products,
vegetables, fruit, and fiber. This bulletin helps you choose foods, meals, and diets that
can reduce chronic disease risks.
Food labels and the Food Guide Pyramid
The Food Guide Pyramid and the Nutrition Facts Label serve as
educational tools to put the Dietary Guidelines into practice. The Pyramid translates the
RDAs and the Dietary Guidelines into the kinds and amounts of food to eat each day. The
Nutrition Facts Label is designed to help you select foods for a diet that will meet the
Dietary Guidelines. Most processed foods now include nutrition information. However,
nutrition labels are not required for foods like coffee and tea (which contain no
significant amounts of nutrients), certain ready-to-eat foods like unpackaged deli and
bakery items, and restaurant food. Labels are also voluntary for many raw foods -- your
grocer may supply this information for the fish, meat, poultry, and raw fruits and
vegetables that are consumed most frequently. Use the Nutrition Facts Label to choose a
healthful diet.
EAT A VARIETY OF FOODS
To obtain the nutrients and other substances needed for good
health, vary the foods you eat.Foods contain combinations of nutrients and other healthful
substances. No single food can supply all nutrients in the amounts you need. For example,
oranges provide vitamin C but no vitamin B12; cheese provides vitamin B12 but no vitamin
C. To make sure you get all of the nutrients and other substances needed for health,
choose the recommended number of daily servings from each of the five major food groups
displayed in the Food Guide Pyramid. Americans do choose a wide variety of foods. However,
people often choose higher or lower amounts from some food groups than suggested in the
Food Guide Pyramid. The Pyramid shows that foods from the grain products group, along with
vegetables and fruits, are the basis of healthful diets. Enjoy meals that have rice,
pasta, potatoes, or bread at the center of the plate, accompanied by other vegetables and
fruit, and lean and low-fat foods from the other groups. Limit fats and sugars added in
food preparation and at the table. Compare the recommended number of servings in box 1
with what you usually eat.
CHOOSE FOODS FROM EACH OF FIVE FOOD GROUPS
The Food Guide Pyramid illustrates the importance of balance
among food groups in a daily eating pattern. Most of the daily servings of food should be
selected from the food groups that are the largest in the picture and closest to the base
of the Pyramid. Choose most of your foods from the grain products group (6-11
servings), the vegetable group (3-5 servings), and the fruit group (2-4 servings).
Eat moderate amounts of foods from the milk group (2-3 servings) and the meat and beans
group (2-3 servings). Choose sparingly foods that provide few nutrients and are high in
fat and sugars. Note: A range of servings is given for each food group. The smaller
number is for people who consume about 1,600 calories a day, such as many sedentary women.
The larger number is for those who consume about 2,800 calories a day, such as active men.
WHAT COUNTS AS A SERVING?
Grain Products Group (bread, cereal, rice, and pasta):
1 slice of bread or 1 ounce of ready-to-eat cereal or 1/2 cup of cooked
cereal, rice, or pasta
Vegetable Group: 1 cup of raw leafy vegetables or 1/2 cup of other
vegetables cooked or chopped raw or 3/4 cup of vegetable juice
Fruit Group: 1 medium apple, banana, orange or 1/2 cup of chopped, cooked, or
canned fruit or 3/4 cup of fruit juice
Milk Group: 1 cup of milk or yogurt or 1-1/2 ounces of natural cheese or 2
ounces of processed cheese
Meat and Beans Group (meat, poultry, fish, dry beans, eggs, and nuts): 2-3 ounces of
cooked lean meat, poultry, or fish or 1/2 cup of cooked dry beans or 1 egg
counts as 1 ounce of lean meat or Two tablespoons of peanut butter or 1/3 cup of nuts
count as 1 ounce of meat.
* Some foods fit into more than one group. Dry beans, peas, and lentils can be counted
as servings in either the meat and beans group or vegetable group. These "cross
over" foods can be counted as servings from either one or the other group, but not
both. Serving sizes indicated here are those used in the Food Guide Pyramid and based on
both suggested and usually consumed portions necessary to achieve adequate nutrient
intake. They differ from serving sizes on the Nutrition Facts Label, which reflect
portions usually consumed.
Choose different foods within each food group
You can achieve a healthful, nutritious eating pattern with many
combinations of foods from the five major food groups. Choosing a variety of foods within
and across food groups improves dietary patterns because foods within the same group have
different combinations of nutrients and other beneficial substances. For example, some
vegetables and fruits are good sources of vitamin C or vitamin A, while others are high in
folate (page 24); still others are good sources of calcium or iron. Choosing a variety of
foods within each group also helps to make your meals more interesting from day to day.
What about vegetarian diets?
Some Americans eat vegetarian diets for reasons of culture,
belief, or health. Most vegetarians eat milk products and eggs, and as a group, these
lacto-ovo-vegetarians enjoy excellent health. Vegetarian diets are consistent with the
Dietary Guidelines for Americans and can meet Recommended Dietary Allowances for
nutrients. You can get enough protein from a vegetarian diet as long as the variety and
amounts of foods consumed are adequate. Meat, fish, and poultry are major contributors of
iron, zinc, and B vitamins in most American diets, and vegetarians should pay special
attention to these nutrients. Vegans eat only food of plant origin. Because animal
products are the only food sources of vitamin B12, vegans must supplement their diets with
a source of this vitamin. In addition, vegan diets, particularly those of children,
require care to ensure adequacy of vitamin D and calcium, which most Americans obtain from
milk products.
Foods vary in their amounts of calories and nutrients
Some foods such as grain products, vegetables, and fruits have
many nutrients and other healthful substances but are relatively low in calories. Fat and
alcohol are high in calories. Foods high in both sugars and fat contain many calories but
often are low in vitamins, minerals, or fiber. People who do not need many calories or who
must restrict their food intake need to choose nutrient-rich foods from the five major
food groups with special care. They should obtain most of their calories from foods that
contain a high proportion of essential nutrients and fiber. Growing children, teenage
girls, and women have higher needs for some nutrients. .Many women and adolescent girls
need to eat more calcium-rich foods to get the calcium needed for healthy bones throughout
life. By selecting low fat or fat-free milk products and other low fat calcium sources, they
can obtain adequate calcium and keep fat intake from being too high (box 3). Young
children, teenage girls, and women of childbearing age should also eat enough iron-rich
foods, such as lean meats and whole-grain or enriched white bread, to keep the body's iron
stores at adequate levels.
Enriched and fortified foods have nutrients added to them
National policy requires that specified amounts of nutrients be
added to enrich some foods. For example, enriched flour and bread contain added thiamin,
riboflavin, niacin, and iron; skim milk, lowfat milk, and margarine are usually enriched
with vitamin A; and milk is usually enriched with vitamin D. Fortified foods may have one
or several nutrients added in extra amounts. The number and quantity of nutrients added
vary among products. Fortified foods may be useful for meeting special dietary needs. Read
the ingredient list to know which nutrients are added to foods. How these foods fit into
your total diet will depend on the amounts you eat and the other foods you consume.
BALANCE THE FOOD YOU EAT WITH PHYSICAL ACTIVITY
Many Americans gain weight in adulthood, increasing their risk
for high blood pressure, heart disease, stroke, diabetes, certain types of cancer,
arthritis, breathing problems, and other illness. Therefore, most adults should not gain
weight. If you are overweight and have one of these problems, you should try to lose
weight, or at the very least, not gain weight. If you are uncertain about your risk of
developing a problem associated with overweight, you should consult a health professional.
How to maintain your weight
In order to stay at the same body weight, people must balance the amount of calories in
the foods and drinks they consume with the amount of calories the body uses. Physical
activity is an important way to use food energy. Most Americans spend much of their
working day in activities that require little energy. In addition, many Americans of all
ages now spend a lot of leisure time each day being inactive, for example, watching
television or working at a computer. To burn calories, devote less time to sedentary
activities like sitting. Spend more time in activities like walking to the store or around
the block. Use stairs rather than elevators. Less sedentary activity and more vigorous
activity may help you reduce body fat and disease risk. Try to do 30 minutes or more of
moderate physical activity on most -- preferably all -- days of the week.
The kinds and amounts of food people eat affect their ability to maintain weight.
High-fat foods contain more calories per serving than other foods and may increase the
likelihood of weight gain. However, even when people eat less high-fat food, they still
can gain weight from eating too much of foods high in starch, sugars, or protein. Eat a
variety of foods, emphasizing pasta, rice, bread, and other whole-grain foods as well as
fruits and vegetables. These foods are filling, but lower in calories than foods rich in
fats or oils.
The pattern of eating may also be important. Snacks provide a large percentage of daily
calories for many Americans. Unless nutritious snacks are part of the daily meal plan,
snacking may lead to weight gain. A pattern of frequent binge-eating, with or without
alternating periods of food restriction, may also contribute to weight problems.
Maintaining weight is equally important for older people who begin to lose weight as they
age. Some of the weight that is lost is muscle. Maintaining muscle through regular
activity helps to keep older people feeling well and helps to reduce the risk of falls and
fractures.
How to evaluate your body weight
Healthy weight ranges for adult men and women of all ages are
shown in figure 3. See where your weight falls on the chart for people of your height. The
health risks due to excess weight appear to be the same for older as for younger adults.
Weight ranges are shown in the chart because people of the same height may have equal
amounts of body fat but different amounts of muscle and bone. However, the ranges do not
mean that it is healthy to gain weight, even within the same weight range. The higher
weights in the healthy weight range apply to people with more muscle and bone. Weights
above the healthy weight range are less healthy for most people. The further you are above
the healthy weight range for your height, the higher your weight-related risk (figure 3).
Weights slightly below the range may be healthy for some people but are sometimes the
result of health problems, especially when weight loss is unintentional.
Location of body fat
Research suggests that the location of body fat also is an
important factor in health risks for adults. Excess fat in the abdomen (stomach area) is a
greater health risk than excess fat in the hips and thighs. Extra fat in the abdomen is
linked to high blood pressure, diabetes, early heart disease, and certain types of cancer.
Smoking and too much alcohol increase abdominal fat and the risk for diseases related to
obesity. Vigorous exercise helps to reduce abdominal fat and decrease the risk for these
diseases. The easiest way to check your body fat distribution is to measure around your
waistline with a tape measure and compare this with the measure around your hips or
buttocks to see if your abdomen is larger. If you are in doubt, you may wish to seek
advice from a health professional.
Problems with excessive thinness
Being too thin can occur with anorexia nervosa, other eating
disorders, or loss of appetite, and is linked to menstrual irregularity and osteoporosis
in women, and greater risk of early death in both women and men. Many people -- especially
women -- are concerned about body weight, even when their weight is normal. Excessive
concern about weight may cause or lead to such unhealthy behaviors as excessive exercise,
self-induced vomiting, and the abuse of laxatives or other medications. These practices
may only worsen the concern about weight. If you lose weight suddenly or for unknown
reasons, see a physician. Unexplained weight loss may be an early clue to a health
problem.
If you need to lose weight
You do not need to lose weight if your weight is already within
the healthy range in the figure, if you have gained less than 10 pounds since you reached
your adult height, and if you are otherwise healthy. If you are overweight and have excess
abdominal fat, a weight-related medical problem, or a family history of such problems, you
need to lose weight. Healthy diets and exercise can help people maintain a healthy weight,
and may also help them lose weight. It is important to recognize that overweight is a
chronic condition which can only be controlled with long-term changes. To reduce caloric
intake, eat less fat and control portion sizes (box 6). If you are not physically active,
spend less time in sedentary activities such as watching television, and be more active
throughout the day. As people lose weight, the body becomes more efficient at using energy
and the rate of weight loss may decrease. Increased physical activity will help you to
continue losing weight and to avoid gaining it back .
TO DECREASE CALORIE INTAKE
- Eat a variety of foods that are low in calories and high in nutrients
- Check the Nutrition Facts Label.
- Eat less fat and fewer high-fat foods.
- Eat smaller portions and limit second helpings of foods high in fat and
calories.
- Eat more vegetables and fruits without fats and sugars added.
- Eat pasta, rice, breads, and cereals without fats and sugars added .
- Eat less sugars and fewer sweets (like candy, cookies, cakes, soda).
- Drink less or no alcohol.
Many people are not sure how much weight they should lose. Weight loss
of only 5-10 percent of body weight may improve many of the problems associated with
overweight, such as high blood pressure and diabetes. Even a smaller weight loss can make
a difference. If you are trying to lose weight, do so slowly and steadily. A generally
safe rate is 1/2-1 pound a week until you reach your goal. Avoid crash weight-loss diets
that severely restrict calories or the variety of foods. Extreme approaches to weight
loss, such as self-induced vomiting or the use of laxatives, amphetamines, or diuretics,
are not appropriate and can be dangerous to your health.
Weight regulation in children
Children need enough food for proper growth. To promote growth
and development and prevent overweight, teach children to eat grain products; vegetables
and fruits; lowfat milk products or other calcium-rich foods; beans, lean meat, poultry,
fish or other protein-rich foods; and to participate in vigorous activity. Limiting
television time and encouraging children to play actively in a safe environment are
helpful steps. Although limiting fat intake may help to prevent excess weight gain in
children, fat should not be restricted for children younger than 2 years of age. Helping
overweight children to achieve a healthy weight along with normal growth requires more
caution. Modest reductions in dietary fat, such as the use of lowfat milk rather than
whole milk, are not hazardous. However, major efforts to change a child's diet should be
accompanied by monitoring of growth by a health professional at regular intervals.
PLENTY OF GRAIN PRODUCTS, VEGETABLES, AND FRUITS
Grain products, vegetables, and fruits are key parts of a varied
diet. They are emphasized in this guideline because they provide vitamins, minerals,
complex carbohydrates (starch and dietary fiber), and other substances that are important
for good health. They are also generally low in fat, depending on how they are prepared
and what is added to them at the table. Most Americans of all ages eat fewer than the
recommended number of servings of grain products, vegetables, and fruits, even though
consumption of these foods is associated with a substantially lower risk for many chronic
diseases, including certain types of cancer.
Most of the calories in your diet should come from grain products, vegetables, and
fruits Once a patient clears their original symptoms, they have heightened reactivity and
food challenges are more unpleasant, risky, and symptoms from single food reactions often
last several days. These include grain products high in complex carbohydrates -- breads,
cereals, pasta, rice -- found at the base of the Food Guide Pyramid, as well as vegetables
such as potatoes and corn. Dry beans (like pinto, navy, kidney, and black beans) are
included in the meat and beans group of the Pyramid, but they can count as servings of
vegetables instead of meat alternatives.
Plant foods provide fiber Because there are different types of fiber in foods, choose a
variety of foods daily. Eating a variety of fiber-containing plant foods is important for
proper bowel function, can reduce symptoms of chronic constipation, diverticular disease,
and hemorrhoids, and may lower the risk for heart disease and some cancers. However, some
of the health benefits associated with a high-fiber diet may come from other components
present in these foods, not just from fiber itself. For this reason, fiber is best
obtained from foods rather than supplements. Plant foods provide a variety of vitamins and
minerals essential for health. Most fruits and vegetables are naturally low in fat and
provide many essential nutrients and other food components important for health. These
foods are excellent sources of vitamin C, vitamin B6, carotenoids, including those which
form vitamin A and folate . The antioxidant nutrients found in plant foods (e.g., vitamin
C, carotenoids, vitamin E, and certain minerals) are presently of great interest to
scientists and the public because of their potentially beneficial role in reducing the
risk for cancer and certain other chronic diseases. Scientists are also trying to
determine if other substances in plant foods protect against cancer.
LOW FAT AND CHOLESTEROL
Some dietary fat is needed for good health. Fats supply energy
and essential fatty acids and promote absorption of the fat-soluble vitamins A, D, E, and
K. Most people are aware that high levels of saturated fat and cholesterol in the diet are
linked to increased blood cholesterol levels and a greater risk for heart disease. More
Americans are now eating less fat, saturated fat, and cholesterol-rich foods than in the
recent past, and fewer people are dying from the most common form of heart disease. Still,
many people continue to eat high-fat diets, the number of overweight people has increased,
and the risk of heart disease and certain cancers (also linked to fat intake) remains
high. This guideline emphasizes the continued importance of choosing a die with less total
fat, saturated fat, and cholesterol.Foods high in fat should be used sparingly. Some foods
and food groups in the Food Guide Pyramid are higher in fat than others. Fats and oils,
and some types of desserts and snack foods that contain fat provide calories but few
nutrients. Many foods in the milk group and in the meat and beans group (which includes
eggs and nuts, as well as meat, poultry, and fish) are also high in fat, as are some
processed foods in the grain group. Choosing lower fat options among these foods allows
you to eat the recommended servings from these groups and increase the amount and variety
of grain products, fruits, and vegetables in your diet without going over your calorie
needs.
Fat, whether from plant or animal sources, contains more than twice the number of
calories of an equal amount of carbohydrate or protein. Choose a diet that provides no
more than 30 percent of total calories from fat. The upper limit on the grams of fat in
your diet will depend on the calories you need (box 10). Cutting back on fat can help you
consume fewer calories. For example, at 2,000 calories per day, the suggested upper limit
of calories from fat is about 600 calories. Sixty-five grams of fat contribute about 600
calories (65 grams of fat x 9 calories per gram = about 600 calories). On the Nutrition
Facts Label, 65 grams of fat is the Daily Value for a 2,000-calorie intake
Fats contain both saturated and unsaturated (monounsaturated and polyunsaturated) fatty
acids. Saturated fat raises blood cholesterol more than other forms of fat. Reducing
saturated fat to less than 10 percent of calories will help you lower your blood
cholesterol level. The fats from meat, milk, and milk products are the main sources of
saturated fats in most diets. Many bakery products are also sources of saturated fats.
Vegetable oils supply smaller amounts of saturated fat. On the Nutrition Facts Label, 20
grams of saturated fat (9 percent of caloric intake) is the Daily Value for a
2,000-calorie diet (figure 4).
Monounsaturated and polyunsaturated fat. Olive and canola oils are particularly high in
monounsaturated fats; most other vegetable oils, nuts, and high-fat fish are good sources
of polyunsaturated fats. Both kinds of unsaturated fats reduce blood cholesterol when they
replace saturated fats in the diet. The fats in most fish are low in saturated fatty acids
and contain a certain type of polyunsaturated fatty acid (omega-3) that is under study
because of a possible association with a decreased risk for heart disease in certain
people. Remember that the total fat in the diet should be consumed at a moderate level --
that is, no more than 30 percent of calories. Mono- and polyunsaturated fat sources should
replace saturated fats within this limit.Partially hydrogenated vegetable oils, such as
those used in many margarines and shortenings, contain a particular form of unsaturated
fat known as trans-fatty acids that may raise blood cholesterol levels,although not as
much as saturated fat.
Choose a diet low in cholesterol
The body makes the cholesterol it requires. In addition,
cholesterol is obtained from food. Dietary cholesterol comes from animal sources such as
egg yolks, meat (especially organ meats such as liver), poultry, fish, and higher fat milk
products. Many of these foods are also high in saturated fats. Choosing foods with less
cholesterol and saturated fat will help lower your blood cholesterol levels. The Nutrition
Facts Label lists the Daily Value for cholesterol as 300 mg. You can keep your cholesterol
intake at this level or lower by eating more grain products, vegetables and fruits, and by
limiting intake of high cholesterol foods.
-
Use fats and oils sparingly in cooking and at the table.
-
Use small amounts of salad dressings and spreads such as butter, margarine, and
mayonnaise. Consider using lowfat or fat-free dressings for salads.
-
Choose vegetable oils and soft margarines most often because they are lower in saturated
fat than solid shortenings and animal fats, even though their caloric content is the same.
-
Check the Nutrition Facts Label to see how much fat and saturated fat are in a serving;
choose foods lower in fat and saturated fat.
Advice for children
Advice in the previous sections does not apply to infants and
toddlers below the age of 2 years. After that age, children should gradually adopt a diet
that, by about 5 years of age, contains no more than 30 percent of calories from fat. As
they begin to consume fewer calories from fat, children should replace these calories by
eating more grain products, fruits, vegetables, and lowfat milk products or other
calcium-rich foods, and beans, lean meat, poultry, fish, or other protein-rich foods.
CHOOSE A DIET MODERATE IN SUGARS
Sugars come in many forms Sugars are carbohydrates. Dietary
carbohydrates also include the complex carbohydrates starch and fiber. During digestion
all carbohydrates except fiber break down into sugars. Sugars and starches occur naturally
in many foods that also supply other nutrients. Examples of these foods include milk,
fruits, some vegetables, breads, cereals, and grains. Americans eat sugars in many forms,
and most people like their taste. Some sugars are used as natural preservatives,
thickeners, and baking aids in foods; they are often added to foods during processing and
preparation or when they are eaten. The body cannot tell the difference between naturally
occurring and added sugars because they are identical chemically.
Sugars, health, and weight maintenance
Scientific evidence indicates that diets high in sugars do not
cause hyperactivity or diabetes. The most common type of diabetes occurs in overweight
adults. Avoiding sugars alone will not correct overweight. To lose weight reduce the total
amount of calories from the food you eat and increase your level of physical activity. If
you wish to maintain your weight when you eat less fat, replace the lost calories from fat
with equal calories from fruits, vegetables, and grain products, found in the lower half
of the Food Guide Pyramid. Some foods that contain a lot of sugars supply calories but few
or no nutrients (box 12). These foods are located at the top of the Pyramid.
For very active people with high calorie needs, sugars can be an additional source of
energy. However, because maintaining a nutritious diet and a healthy weight is very
important, sugars should be used in moderation by most healthy people and sparingly by
people with low calorie needs. This guideline cautions about eating sugars in large
amounts and about frequent snacks of foods and beverages containing sugars that supply
unnecessary calories and few nutrients.
ON A FOOD LABEL, SUGARS INCLUDE brown sugar, corn sweetener, corn syrup, fructose,
fruit juice concentrate, glucose (dextrose), high-fructose corn syrup, honey, invert
sugar, lactose, maltose, molasses, raw sugar, table sugar (sucrose), syrup. A food is
likely to be high in sugars if one of the above terms appears first or second in the
ingredients list, or if several of them are listed.
Sugar substitutes such as sorbitol, saccharin, and aspartame are ingredients in many
foods. Most sugar substitutes do not provide significant calories and therefore may be
useful in the diets of people concerned about calorie intake. Foods containing sugar
substitutes, however, may not always be lower in calories than similar products that
contain sugars. Unless you reduce the total calories you eat, the use of sugar substitutes
will not cause you to lose weight.
Both sugars and starches can promote tooth decay. The more often you eat foods that
contain sugars and starches, and the longer these foods are in your mouth before you brush
your teeth, the greater the risk for tooth decay. Thus, frequent eating of foods high in
sugars and starches as between-meal snacks may be more harmful to your teeth than eating
them at meals and then brushing. Regular daily dental hygiene, including brushing with a
fluoride toothpaste and flossing, and an adequate intake of fluoride, preferably from
fluoridated water, will help you prevent tooth decay
CHOOSE A DIET MODERATE IN SALT AND SODIUM
Sodium and salt are found mainly in processed and prepared foods
Sodium and sodium chloride -- known commonly as salt -- occur naturally in foods, usually
in small amounts. Salt and other sodium-containing ingredients are often used in food
processing. Some people add salt and salty sauces, such as soy sauce, to their food at the
table, but most dietary sodium or salt comes from foods to which salt has already been
added during processing or preparation. Although many people add salt to enhance the taste
of foods, their preference may weaken with eating less salt. Sodium plays an essential
role in regulation of fluids and blood pressure. Many studies in diverse populations have
shown that a high sodium intake is associated with higher blood pressure. Most evidence
suggests that many people at risk for high blood pressure reduce their chances of
developing this condition by consuming less salt or sodium. Some questions remain, partly
because other factors may interact with sodium to affect blood pressure.
Other factors affect blood pressure
Following other guidelines in the Dietary Guidelines for Americans may also help
prevent high blood pressure. An important example is the guideline on weight and physical
activity. The role of body weight in blood pressure control is well documented. Blood
pressure increases with weight and decreases when weight is reduced. The guideline to
consume a diet with plenty of fruits and vegetables is relevant because fruits and
vegetables are naturally lower in sodium and fat and may help with weight reduction and
control. Consuming more fruits and vegetables also increases potassium intakes which may
help to reduce blood pressure. Increased physical activity helps lower blood pressure and
control weight. Alcohol consumption has also been associated with high blood pressure.
Another reason to reduce salt intake is the fact that high salt intakes may increase the
amount of calcium excreted in the urine and, therefore, increase the body's need for
calcium.
Sodium has an important role in the body. However, most Americans consume more sodium
than is needed. The Nutrition Facts Label lists a Daily Value of 2,400 mg per day for
sodium [2,400 mg sodium per day is contained in 6 grams of sodium chloride (salt)]. In
household measures, one level teaspoon of salt provides about 2,300 milligrams of sodium.
Most people consume more than this amount. There is no way at present to tell who might
develop high blood pressure from eating too much sodium. However, consuming less salt or
sodium is not harmful and can be recommended for the healthy normal adult .
TO CONSUME LESS SALT AND SODIUM
-- Read the Nutrition Facts Label to determine the amount of sodium in the foods you
purchase. The sodium content of processed foods -- such as cereals, breads, soups, and
salad dressings -- often varies widely.
Choose foods lower in sodium and ask your grocer or supermarket to offer more
low-sodium foods. Request less salt in your meals when eating out or traveling.- If you
salt foods in cooking or at the table, add small amounts. Learn to use spices and herbs,
rather than salt, to enhance the flavor of food.-- When planning meals, consider that
fresh and most plain frozen vegetables are low in sodium.-- When selecting canned foods,
select those prepared with reduced or no sodium. Remember that fresh fish, poultry, and
meat are lower in sodium than most canned and processed ones. Choose foods lower in sodium
content. Many frozen dinners, packaged mixes, canned soups, and salad dressings contain a
considerable amount of sodium. Remember that condiments such as soy and many other sauces,
pickles, and olives are high in sodium. Ketchup and mustard, when eaten in large amounts,
can also contribute significant amounts of sodium to the diet. Choose lower sodium
varieties. Choose fresh fruits and vegetables as a lower sodium alternative to salted
snack foods.
DRINK ALCOHOLIC BEVERAGES IN MODERATION
Alcoholic beverages supply calories but few or no nutrients. The
alcohol in these beverages has effects that are harmful when consumed in excess. These
effects of alcohol may alter judgment and can lead to dependency and a great many other
serious health problems. Alcoholic beverages have been used to enhance the enjoyment of
meals by many societies throughout human history. If adults choose to drink alcoholic
beverages, they should consume them only in moderation .
Moderation is defined as no more than one drink per day for women and no more than two
drinks per day for men. Count as a drink
-
12 ounces of regular beer (150 calories)
-
5 ounces of wine (100 calories)
-
1.5 ounces of 80-proof distilled spirits (100 calories)
Current evidence suggests that moderate drinking is associated with a lower risk for
coronary heart disease in some individuals. However, higher levels of alcohol intake raise
the risk for high blood pressure, stroke, heart disease, certain cancers, accidents,
violence, suicides, birth defects, and overall mortality (deaths). Too much alcohol may
cause cirrhosis of the liver, inflammation of the pancreas, and damage to the brain and
heart. Heavy drinkers also are at risk of malnutrition because alcohol contains calories
that may substitute for those in more nutritious foods.
Who should not drink?
Some people should not drink alcoholic beverages at all.
These include:
-
Children and adolescents.
-
Individuals of any age who cannot restrict their drinking to moderate levels. This is a
special concern for recovering alcoholics and people whose family members have alcohol
problems.
-
Women who are trying to conceive or who are pregnant. Major birth defects, including
fetal alcohol syndrome, have been attributed to heavy drinking by the mother while
pregnant. While there is no conclusive evidence that an occasional drink is harmful to the
fetus or to the pregnant woman, a safe level of alcohol intake during pregnancy has not
been established.
-
Individuals who plan to drive or take part in activities that require attention or
skill. Most people retain some alcohol in the blood up to 2-3 hours after a single drink.
-
Individuals using prescription and over-the-counter medications. Alcohol may alter the
effectiveness or toxicity of medicines. Also, some medications may increase blood alcohol
levels or increase the adverse effect of alcohol on the brain.
