Foreword

F

ood nourishes us in many ways. Eating is one

of life’s pleasures. Food is tied to memories of
our youth and to social occasions, celebrations,
and other aspects of our culture. Food also
fuels our bodies. What we eat is a controllable factor
in keeping us as healthy and as fit as possible.
The fundamentals for fostering a healthy body
remain constant. A well-balanced approach to eating
and getting plenty of rest and physical activity are, and
always have been, keys to good health. Research about
nutrition and its impact on everything from childhood
development to disease control and prevention, however, shows that our knowledge about the role of nutrition in a healthful lifestyle is continually evolving.
Since the last published edition of this book, scientists have made exciting discoveries about nutrition
and how much it can affect our overall health. We now
know more about health-promoting substances in
fruits, vegetables, and grain products called phytonutrients. We have expanded the way we look at vitamins
and minerals. Consumers are increasingly turning to
“alternative” medicine and therapies to treat or prevent
disease. In addition, the impact of biotechnology on
the food supply is changing the way we think about
how our food is grown and processed.

All these important issues and more are discussed
in the second edition of the American Dietetic Association Complete Food and Nutrition Guide. Written
and reviewed by qualified nutrition practitioners—
registered dietitians and dietetic technicians, registered—the book is scientifically based. But more than
that, it is practical and easy to understand. Registered
dietitians counsel people to attain optimal health by
eating a variety of nutrient-rich foods with an emphasis on taste, quality, moderation, balance, and food
safety.
In the second edition of the American Dietetic

Association Complete Food and Nutrition Guide,
Roberta Duyff shows you how to maximize your
health while enjoying food. Her practical suggestions
are backed up by the latest scientific evidence, as
well as by her extensive experience as a registered
dietitian. Best of all, the book can serve as a reference
for your entire family’s health—and it’s right at your
fingertips.
Enjoy the book and optimize your health.
Julie O’Sullivan Maillet, RD, PhD, FADA
President, American Dietetic Association

A

t every phase in developing the American
Dietetic Association Complete Food and
Nutrition Guide, I’ve been grateful and
indebted to the many professionals, colleagues, and friends—in the fields of nutrition and
dietetics, health, family and consumer sciences, food
science, culinary arts, education, and communications—who have shared their knowledge, experience,
and expertise throughout my career. I’m especially
grateful to:
The American Dietetic Association, for the honor
of writing this book on behalf of the association’s more

Introduction

T

he American Dietetic Association Complete
Food and Nutrition Guide has been created
for you as a practical, up-to-date resource
for healthful eating. From cover to cover,
you’ll see how smart eating—combined with physical activity—promotes fitness. As important, you’ll
learn how healthful eating and taste go hand in
hand!
To offer solutions for your everyday eating dilemmas, this book is filled with practical advice—whatever your lifestyle or needs. From weight control to
heart-healthy eating . . . supermarket shopping to eating out . . . food safety to kitchen nutrition . . . vegetarian eating to sports nutrition, you’ll find many tips
for ease, convenience, and good taste. Look for today’s
“hot” food issues, too: phytonutrients, functional
foods, dietary supplements, and food biotechnology,
among others.
As your complete resource on nutrition, you can
refer to this book again and again at every age and
stage of your life—from choosing the healthiest baby
food or feeding a child or teen, to dealing with unique
nutrition needs in a woman’s life or challenges of
aging. It’s also filled with advice for preventing, slowing, or dealing with heart disease, cancer, diabetes,
and other common health problems. This book is
meant for you, and for all those you care about . . .

perhaps a child, spouse, companion, aging parent,
or friend.
For your personal nutrition “checkup,” you’ll find
opportunities to assess your own everyday food

choices. Start in chapter 1 with “Looking for ‘Healthy
Solutions’?” to identify your personal eating challenges. For more information, each question refers
you to in-depth answers throughout the book. In fact,
in almost every chapter, “Your Nutrition Checkup”
gives you a close-up look at your own food decisions.
Whenever nutrition makes the news (print, television, radio, or online), this book can help you judge
the headlines and separate sound fact from fad.
Its food and nutrition advice comes from the American Dietetic Association, the authority the United
States turns to for food and nutrition advice, with
more than eighty-five years of nutrition expertise and
research.
With questions posed to nutrition experts—in part
through the American Dietetic Association’s Knowledge Center—thousands of consumers have helped
shape the focus and content of the American Dietetic
Association Complete Food and Nutrition Guide. We
hope the answers to their food and nutrition questions
will also answer many of yours!
Read, enjoy, be active, and eat healthy . . . for life!

Food Choices for Fitness

Y

our life is filled with choices! Every day you
make thousands of choices, many related to
food. Some seem trivial. Others are important. A few may even set the course of your
life. But as insignificant as a single choice may seem,
made over and over, it can have a major impact on your
health—and your life!
This book is about choices—those you, your family, and your friends make every day about food, nutrition, and health. Within its pages, you’ll find reliable
nutrition information and sound advice, based on scientific evidence. It offers you practical ways to eat
healthfully in almost any situation and at every phase
of life. And it encourages you to enjoy the pleasures
of food. After all, taste is the number one reason most
people choose one food over another.
Most important, the practical tips and flexible
guidelines on its pages help you choose nutritious, flavorful foods to match your own needs, preferences,

and lifestyle—even as your life and family situation
change. Eating for health is one of the wisest decisions
you’ll ever make!

optimal health and overall well-being. Fitness is your
good health—at its very best.
Being fit defines every aspect of your health—not
only your physical health, but your emotional and
mental well-being, too. In fact, they’re interconnected.
Smart eating and active living are fundamental to all
three. When you’re fit, you have:
ⅷ Energy to do what’s important to you and to be
more productive
ⅷ Stamina and a positive outlook to handle the
mental challenges and emotional ups and downs
of everyday life, and to deal with stress
ⅷ Reduced risk for many health problems, including serious, often life-changing diseases, such as
heart disease, cancer, diabetes, and osteoporosis
ⅷ The chance to look and feel your best
ⅷ Physical strength and endurance to protect yourself in case of an emergency
ⅷ A better chance for a higher quality of life, and
perhaps a longer one, too

Fit Is Ageless

Fitness: Your Overall Health!
What does being fit mean to you? Perhaps, being free
of disease and other health problems? Or having
plenty of energy, or a trim or muscular body, or the
ability to finish a 10K run? Actually, “fitness” is far

broader and more personal. It refers to your own

Fitness at every age and stage in life depends on
healthful eating and active living. The sooner you
make them your priorities, the better your health.
That, too, is what this book is all about—how to
eat for health and stay physically active throughout the
cycle of life, and enjoy great-tasting food along the
way!

Good nutrition and regular physical activity are two
lifestyle habits that promote fitness—but certainly not
the only ones. To stay fit, make other lifestyle choices
for good health, too: get adequate sleep, avoid smoking, manage stress, drink alcoholic beverages only in
moderation (if you drink), wear your seat belt, observe
good hygiene, get regular medical checkups, obtain
adequate health care—to name a few.

Smart Eating: Fuel for Fitness
What does it take to be fit? You don’t need special or
costly foods, or fancy exercise equipment or health
club membership. You don’t need to give up your

favorite foods, or set up a tedious system of eating
rules or calorie counting. And you don’t need to hit a
specific weight on the bathroom scale.
You’ve heard the term “nutrition” all your life. The
food-fitness connection is what it’s all about. In a nutshell, nutrition is how food nourishes your body. And

Your Nutrition Checkup
Ready for Healthier Eating?
Where do you fit on this “healthy eating” readiness test?
Check one.
□ “My food choices are okay as they are.” Okay, but
read on to find out why you might consider taking
a few steps in the future to eat for better health (and
perhaps move more, too).
□ “I’ll change my eating habits sometime, but I can’t
make myself do it now.” Good initial thought. Check
here for sensible, realistic ways to eat smarter (and
move more)—but now rather than later. The sooner
you start, the greater the benefits.
□ “I’m ready to eat smarter, starting now.” Good. Look
through these chapters for small steps to healthful
eating that you can take. As you achieve them, try a
few more. Be active, too.
□ “I’m already a ‘healthy eater.’” Great, keep it up! Flip
through this book for more practical ways to eat
smart. In fact, get adventuresome with your eating.
And take time for active living.
□ “Healthy eating and active living are second nature
to me.” Excellent! Share the practical advice here
and your own success with someone else!


being well nourished depends on getting enough of the
nutrients your body needs—but not too much.
At every stage in life, healthful eating fuels fitness.
Well-nourished infants, children, and teens grow,
develop, and learn better. Good nutrition helps ensure
a healthy pregnancy and successful breast-feeding.
And healthful eating and active living help people at
any age feel their best, work productively, and lower
their risks for some diseases.
Today’s understanding of nutrition is based on years
of scientific study. Interest in food and health actually
has a long history and was even recorded by the
ancient Greeks. But it wasn’t until the nineteenth century that the mysteries of nutrition began to be solved.
Since then, scientists have been able to answer many
nutrition questions. And research continues as scientists explore emerging questions about food, nutrients,
phytonutrients, and their role in health.
Today we know that healthful eating dramatically
lowers the risk for the main causes of disability and
death in the United States: heart disease, certain cancers, diabetes, stroke, and osteoporosis. Good nutrition and regular physical activity also can lower risks
for obesity, high blood pressure, and high blood cholesterol—all risk factors for serious disease.
Nutrition advice, with the consensus of today’s
nutrition experts, is supported by solid scientific evidence. So unlike the ancients, you have a valid basis for
choosing food for health. It’s up to you to apply nutrition principles and advice for your own well-being.
To make wise food choices, you need sciencebased nutrition information. What you know—and
don’t know—just may surprise you!

Smart Eating: Pleasure, Too!
Why do you choose one food over another? Besides
the nutrition benefits, food is a source of pleasure,

adventure, and great taste! It’s no surprise that people
entertain and celebrate with food, or look forward to
a special dish.
Your own food choices reflect you and what’s
important to you: your culture, your surroundings, the
people around you, your view of yourself, the foods
available to you, your emotions, and certainly what
you know about food and nutrition. To eat for health,
you don’t need to give up your food favorites. Simply

learn how to fit them in. Good nutrition adds pleasure
to eating—especially as you eat a greater variety of
vegetables, fruits, grain products, and other nutrientrich foods.
Throughout this book, you’ll get plenty of guidance
to do just that! You’ll learn more about nutrition and
fitness—and how you can eat the foods you like, even
try new foods, in an eating plan that promotes your
personal fitness.

what you eat and how much you move are key factors
in your fitness equation.

What’s the secret to healthful eating? It’s no secret
at all, just solid advice. In a nutshell, enjoy an overall
approach to eating, with most of your energy, or calories, coming from grain products, vegetables, fruits,
lower-fat milk products, lean meat, fish, poultry, and
legumes. Consume less energy, or calories, from fats
and sweets. Let’s explore just what that means—and
how to do it.
In ten statements, the Dietary Guidelines for Americans sum up the basics about eating and being active
for health. Follow their advice, and promote your
health for the long run, while reducing your risks for
many health problems, including some leading causes
of disability and death among Americans. By following the guidelines you may reduce risk factors (obesity, high blood pressure, and high blood cholesterol)
that lead to chronic disease. And you may lower your
chances for heart disease, some cancers, diabetes,
stroke, and osteoporosis.
So if you’re not following the Dietary Guidelines
already, why not? And why not start now?
Developed by the U.S. Department of Agriculture
and the U.S. Department of Health and Human Services, the Dietary Guidelines have been developed for
you—in fact, for all healthy Americans ages two and
over. Updated every five years, these guidelines offer
the most current, science-based advice, based on the
consensus of many nutrition experts.

The Dietary Guidelines
are flexible, with plenty of
room for you to eat what
you enjoy and eat for health!
They’re sensible, too, recognizing that what you eat
over several days, rather
than for just one day, or one
meal or snack, is what really
counts!
The advice of the Dietary
Guidelines is summed up
with the ABCs for good
health:
ⅷ Aim for fitness . . .
with a healthy body
weight and active living.
ⅷ Build a healthy base
. . . with a variety of nutritious, health-promoting
foods, kept safe to eat.
ⅷ Choose sensibly . . . without overdoing on fat,
especially saturated fat; sugars; salt; and for adults
who choose to drink them, alcoholic beverages.

Aim for Fitness
When you focus on fitness, remember that two guidelines—aiming for a healthy weight and putting
physical activity into your everyday life—pay off:
helping you work productively, enjoy life, and feel
your best. These same guidelines help children and
teens thrive, develop, and succeed at school.

“Weight” for Health

Guideline 1: Aim for a healthy weight.
Are you at your healthy weight? Appearance or fitting into a clothes size are commonly cited reasons to
maintain a healthy weight. Yet, even a few pounds of
excess weight may be more risky to your health
than you think. Research shows that overweight and
obesity increase the risk factors for chronic disease,
including high blood pressure and high blood
cholesterol, and up the chances for developing serious health problems: heart disease, stroke, diabetes,
certain types of cancer, arthritis, and breathing prob-

lems, among others. Did you
know that premature death is
linked to excess body weight
as well? And that being overweight also can take a toll on
emotional health?
Despite the known risks,
overweight and obesity have
become a national and global
pandemic, and not just for
adults. The typical American
adult gains weight with every
decade. The risk for and the
actual incidence of overweight
among children and teens are
rising dramatically, too.
No matter what your age,
aim for a healthy weight. For
adult women, more than 35

inches around the waistline,
and for men, more than 40
inches around the waistline are quick markers for
excess abdominal fat and the potential risk for some
health problems. What’s your “measure” of fitness?
As an adult in a healthy weight range, set your goal
on maintaining your present weight. However, if
you’re overweight, and especially if you already have
one of these health problems, you’re wise to trim down
gradually. At the very least, manage your weight so
you don’t gain more. (Note: Being overweight is a
problem when extra pounds come from excess body
fat. Because strenuous workouts build muscle, extra
weight from muscle isn’t a problem.)
If children and teens can keep a healthy weight
while they’re growing, their chance of being overweight adults is lower. More active play, fewer sedentary activities (such as TV and video and computer
games), and healthful eating are their best strategies to
a healthy weight.
For children, teens, and adults of any age, a healthy
weight is key to a long, healthy, and productive life.
The smart way to achieve that goal? Eat mostly nutrient-rich foods such as vegetables, fruit, grain products,
lean meats, and low-fat dairy foods, choose sensible
food portions, and keep physically active. For more
about weight management and health, see chapter 2,
“Your Healthy Weight.”

Move It: The Food-Activity Connection

Guideline 2: Be physically active each day.
Physical activity is essential for your health, yet
most Americans don’t get enough. For those reasons,
being active every day is its own Dietary Guideline!
Your healthy weight is one key reason for regular
physical activity. But the benefits extend much farther.
See “Ten Reasons to Make the ‘Right Moves’” later
in this chapter. Try to accumulate each day at least
thirty minutes of moderate physical activity if you’re
an adult, and sixty minutes for children and teens. For
examples of moderate physical activity, see “Moderate Activity: What Is It?” below.
Get active . . . stay active . . . or become even more
active. Spread out your activity, or do it all at once;
either way offers benefits. If you haven’t been active,

their body weight . . . “Get Physical!” in chapter 2

MODERATE ACTIVITY: WHAT IS IT?
If some activities use more energy than others, you may wonder: Just what does “moderate physical activity” really mean? It equates to the energy you need to walk 2 miles in 30 minutes.
Moderate physical activity uses about 150 calories a day, or about 1,000 calories a week.
For that amount of energy expenditure, you might spend more time on less vigorous activities,
such as brisk walking, or spend less time on more vigorous activities, such as running.

Te n R e a s o n s t o M a k e t h e “ R i g h t M o v e s ”
hether you’re involved in sports or simply live
an active lifestyle, physical activity pays big
dividends. Physical activity is the “right move”
for fitness—for almost everyone, not just for athletes.
Consider just a few reasons why:

W

1. Trimmer body. If you’re physically active, you’ll have
an easier time maintaining a healthy weight, or losing weight and keeping it off if you’re overweight.
For more about the benefits of physical activity for
weight management, see chapter 2, “Your Healthy
Weight.”
2. Less risk for health problems. An active lifestyle—or
a sports regimen—can help protect you from many
ongoing health problems.
Studies show that regular physical activity helps
lower risk factors. For example, physical activity
lowers total and LDL (“bad”) cholesterol and triglyceride levels while boosting the HDL (“good”) cholesterol level, controls blood pressure, and improves

blood sugar levels. Your risks for heart disease, type
2 diabetes, and colon cancer also go down when
you fit physical activity into your everyday living.
Active living also may reduce or eliminate the
need for medication to lower blood lipids, lower
blood pressure, or manage diabetes.
3. Stronger bones. Regular, weight-bearing activities
such as walking, running, weight lifting, crosscountry skiing, and soccer help make your bones
stronger. If you’re past age thirty-five, weightbearing exercise helps maintain your bone strength
and reduce your chance of fractures.
4. Stronger muscles. Strength-training activities such
as lifting weights at least two times a week keep
your body strong for sports and everyday living.

start gradually. Work up to longer, more intense activities for more benefits. As you plan, try to fit in physical activities that are especially beneficial:
ⅷ For flexibility, try stretching, yoga, and dancing.
ⅷ For strength, try weight-bearing activities (walking, tennis) for bone strength, and carrying groceries or weight lifting to build muscles.
ⅷ For cardiovascular fitness, try aerobic activities
that increase your heart rate and breathing.

When you’re strong, it’s easier to move, carry, and lift
things. When you exercise your muscles, you also
give your heart a workout. Remember, it’s a muscle,
too. A strong heart pumps blood and nutrients
more easily through your 60,000 miles of blood
vessels.
5. More endurance. You won’t tire as easily when
you’re physically active. And you may have more
stamina during the rest of the day, too.
6. Better mental outlook. Active people describe feelings of psychological well-being and self-esteem

when they make active living a habit. It’s a great way
to reinforce that “can do” attitude.
7. Stress relief and better sleep. Research shows that
physical activity helps your body relax and release
emotional tension. That promotes longer, betterquality sleep, and you may fall asleep faster.
8. Better coordination and flexibility. Your body moves
with greater ease and range of motion when you
stay physically active.
9. Injury protection. When you’re in shape, you more
easily can catch yourself if you slip or trip . . . and
can move away from impending danger more
quickly.
10. Feel younger longer. Research suggests that physical activity slows some effects of aging. Active people have more strength and mobility, and fewer
limitations.
For more about the benefits of physical activity, see
“Active Play: Good Moves for Children” in chapter 16,
and for older adults, “The Reasons Are Many” in chapter 18.

Have You Ever Wondered
. . . if you set a safe pace for physical activity? Take
the “talk-sing test” to find out. If you can talk as
you move, you’re okay. If you’re too breathless to
talk, slow down. And if you can sing, step up your
pace!

Unless you have a health problem, you probably
can start moving more now! Talk to your healthcare
provider first if you have an ongoing health problem—
including heart disease, high blood pressure, diabetes,
osteoporosis, arthritis, or obesity, if you’re at high risk
for heart disease, or if you’re over age forty for men, or
over age fifty for women.

Build a Healthy Base
Four more Dietary Guidelines establish your base for
healthful eating. The familiar Food Guide Pyramid is
an easy-to-use planning guide that helps you get the
nutrients you need from food each day. Vegetables,
fruits, and grains form the foundation of the Pyramid
for good reason: you need plenty of them for good
nutrition and health, and to reduce your health risks. In
fact, try new foods from these groups in place of highcalorie, less nutritious foods you may be used to eating. And always keep your food safe—wherever,
whatever you eat!

Food Variety—a Priority!

Guideline 3: Let the Pyramid guide your food choices.
If variety is the “spice of life,” in your food choices
variety is key to enjoying food and to good nutrition
and health. Each day your body needs the nutrients
and other healthful substances that a variety of food
provides. Most foods and beverages have more than
one nutrient. But no one food or food category has
them all.
The Food Guide Pyramid is an easy guide for what
to eat each day: for variety, so you get a range of nutrients, and for adequacy, so you get enough without
overdoing on calories. In fact, it’s flexible enough to
fit any healthful way of eating and include any food,
even occasional fats and sweets. The Pyramid recommends a range of servings, and identifies serving sizes.
It acts as a guide for an appropriate amount of food
for you.
The Food Guide Pyramid translates nutrient recommendations from the Dietary Reference Intakes
(DRIs) and the Dietary Guidelines for Americans into
practical advice for all healthy people, ages two years
and over. In chapter 10 learn how
to use the Pyramid to plan meals
and snacks.
