Goal
Promote health and reduce chronic disease associated with diet and weight.
Overview
Issues and Trends
Nutrition is essential for growth and development, health, and well-being. Behaviors to promote health should start early in life with breastfeeding^1 and continue through life with the development of healthful eating habits. Nutritional, or dietary, factors contribute substantially to the burden of preventable illnesses and premature deaths in the United States.^2 Indeed, dietary factors are associated with 4 of the 10 leading causes of death: coronary heart disease (CHD), some types of cancer, stroke, and type 2 diabetes.^3 These health conditions are estimated to cost society over $200 billion each year in medical expenses and lost productivity.^4 Dietary factors also are associated with osteoporosis, which affects more than 25 million persons in the United States and is the major underlying cause of bone fractures in postmenopausal women and elderly persons.^5
Many dietary components are involved in the relationship between nutrition and health. A primary concern is consuming too much saturated fat and too few vegetables, fruits, and grain products that are high in complex carbohydrates, dietary fiber, vitamins and minerals, and other substances conducive to health. The 1995 Dietary Guidelines for Americans recommend that, to stay healthy, persons aged 2 years and older should eat a variety of foods; maintain or improve one’s weight by balancing food intake with physical activity; choose a diet that is plentiful in grain products, vegetables, and fruits, moderate in salt, sodium, and sugars, and low in fat, saturated fat, and cholesterol; and, if consuming alcoholic beverages, do so in moderation.^6 The Food Guide Pyramid, introduced in 1992, is an educational tool that conveys recommendations about the number of servings from different food groups each day and other principles of the Dietary Guidelines for Americans.^7
The Dietary Guidelines for Americans also emphasize the need for adequate consumption of iron-rich and calcium-rich foods.^6 Although some progress has been made since the 1970s in reducing the prevalence of iron deficiency among low-income children,^8 much more is needed to improve the health of children of all ages and of women who are pregnant or are of childbearing age. Since the start of this decade, consumption of calcium-rich foods, such as milk products, has generally decreased and is especially low among teenaged girls and young women.^9 Because important sources of calcium also can include other foods with calcium occurring naturally or through fortification as well as dietary supplements, the current emphasis is on tracking total calcium intake from all sources, 

demonstrated by an objective in this focus area. In addition, in recent years there has been a concerted effort to increase the folic acid intake of females of childbearing age through fortification and other means to reduce the risk of neural tube defects.^10, ^11 (See Focus Area 16. Maternal, Infant, and Child Health.)
In general, however, excesses and imbalances of some food components in the diet have replaced once commonplace nutrient deficiencies. Unfortunately, there has been an alarming increase in the number of overweight and obese persons.^12, ^13 Overweight results when a person eats more calories from food (energy) than he or she expends, for example, through physical activity. This balance between energy intake and output is influenced by metabolic and genetic factors as well as behaviors affecting dietary intake and physical activity; environmental, cultural, and socioeconomic components also play a role.
When a body mass index (BMI) cut-point of 25 is used, nearly 55 percent of the U.S. adult population was defined as overweight or obese in 1988-94, compared to 46 percent in 1976-80.^12, ^14, ^15 In particular, the proportion of adults defined as obese by a BMI 30 or greater has increased from 14.5 percent to 22.5 percent.^12 A similar increase in overweight and obesity also has been observed in children above age 6 years in both genders and in all population groups.^16
Many diseases are associated with overweight and obesity. Persons who are overweight or obese are at increased risk for high blood pressure, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems, and some types of cancer. The health outcomes related to these diseases, however, often can be improved through weight loss or, at a minimum, no further weight gain. Total costs (medical costs and lost productivity) attributable to obesity alone amounted to an estimated $99 billion in 1995.^17
Disparities
Disparities in health status indicators and risk factors for diet-related disease are evident in many segments of the population based on gender, age, race and ethnicity, and income. For example, overweight and obesity are observed in all population groups, but obesity is particularly common among Hispanic, African American, Native American, and Pacific Islander women. Furthermore, despite concerns about the increase in overweight and certain excesses in American diets, segments of the population also suffer from undernutrition, including persons who are socially isolated and poor. Over the years, the recognition of the consequences of food insecurity (limited access to safe, nutritious food) has led to the development of national measures and surveys to evaluate food insecurity and hunger and to the ability to assess disparities among different population groups. With food security and other measures of undernutrition, such as growth retardation and iron deficiency, disparities are evident based not only on income but also on race and ethnicity.
In addition, there are concerns about the nutritional status of persons in hospitals, nursing homes, convalescent centers, and institutions; persons with disabilities, including physically, mentally, and developmentally disabled persons in community settings; children in child care facilities; persons living on reservations; persons in correctional facilities; and persons who are homeless. National data about these population groups are currently unavailable or limited. Data also are insufficient to target the fastest growing segment of the population, the old and very old who live independently.
Opportunities
Establishing healthful dietary and physical activity behaviors needs to begin in childhood. Educating school-aged children about nutrition is important to help establish healthful eating habits early in life.^18, ^19 Research suggests that parents who understand proper nutrition can help preschoolers choose healthful foods, but they have less influence on the choices of school-aged children.^20 Thus, the impact of nutrition education on health may be more effective if targeted directly at school-aged children. Unfortunately, a survey done in 1994 showed that only 69 percent of States and 80 percent of school districts required nutrition education for students in at least some grades from kindergarten through 12th grade.^21
A well-designed curriculum that effectively addresses essential nutrition education topics can increase students’ knowledge about nutrition, help shape appropriate attitudes, and help develop the behavioral skills students need to plan, prepare, and select healthful meals and snacks.^18, ^22, ^23 Curricula that encourage specific, healthful eating behaviors and provide students with the skills needed to adopt and maintain those behaviors have led to favorable changes in student dietary behaviors and cardiovascular disease risk factors.^18, ^22, ^23 In order to enhance the effectiveness of these lessons, however, nutrition course work should be part of the core curriculum for the professional preparation of teachers of all grades and should be emphasized in continuing education activities for teachers.
Topics considered to be essential at the elementary, middle and junior high, and senior high school levels include using the Food Guide Pyramid; learning the benefits of healthful eating; making healthful food choices for meals and snacks; preparing healthy meals and snacks; using food labels; eating a variety of foods; eating more fruits, vegetables, and grains; eating foods low in saturated fat and total fat more often; eating more calcium-rich foods; balancing food intake and physical activity; accepting body size differences; and following food safety practices.^18, ^24 In addition, the following topics are considered to be essential at the middle/junior and senior high school levels: the Dietary Guidelines for Americans; eating disorders; healthy weight maintenance; influences on food choices such as families, culture, and media; and goals for dietary improvement.^18
Nutrition education should be taught as part of a comprehensive school health education program, and essential nutrition education topics should be integrated into science and other curricula to reinforce principles and messages learned in the health units. Nutrition education is addressed within a school health education objective. (See Focus Area 7. Educational and Community-Based Programs.) In addition, students must have access to healthful food choices to further enhance the likelihood of adopting healthful dietary practices. For these reasons, monitoring students’ eating practices at school is important.
Although health promotion efforts should begin in childhood, they need to continue throughout adulthood. In particular, public education about the long-term health consequences and risks associated with overweight and how to achieve and maintain a healthy weight is necessary. While many persons attempt to lose weight, studies show that within 5 years a majority of them regain the weight.^25 To maintain weight loss, healthful dietary habits must be coupled with decreased sedentary behavior and increased physical activity and become permanent lifestyle changes. (See Focus Area 22. Physical Activity and Fitness.) Additionally, changes in the physical and social environment may help persons maintain the necessary long-term lifestyle changes for both diet and physical activity.
Policymakers and program planners at the national, State, and community levels can and should provide important leadership in fostering healthful diets and physical activity patterns among Americans. The family and others, such as health care practitioners, schools, worksites, institutional food services and the media, can play a key role in this process. For example, registered dietitians and other qualified health care practitioners can improve health outcomes through efforts focused on nutrition screening, assessment, and primary and secondary prevention.
Food-related businesses can also help consumers achieve healthful diets by providing nutrition information for foods purchased in supermarkets, fast-food outlets, restaurants, and carryout operations. For example, the introduction of a new food label in 1993 has resulted in nutrition information on most processed packaged foods, along with credible health and nutrient content claims and standardized serving sizes.^26 While efforts were made in the 1990s to increase the availability of nutrition information, reduced-fat foods, and other healthful food choices in supermarkets, significant challenges remain on these fronts for away-from-home foods purchased at food service outlets. The importance of addressing these challenges is suggested by recent data indicating that nearly 40 percent of a family’s food budget is spent on away-from-home food, including food from restaurants and fast-food outlets.^27 One analysis found that away-from-home foods are generally higher in saturated fat, total fat, cholesterol, and sodium and lower in dietary fiber, iron, and calcium than at-home foods.^27 Away-from-home sites include restaurants, fast-food outlets, school cafeterias, and vending machines. This study also suggested that persons either eat larger amounts when they eat out, eat higher calorie foods, or both.
Many of the 2010 objectives that address nutrition and overweight in the United States measure in some way the Nation’s progress toward implementing the recommendations of the Dietary Guidelines for Americans. The recommendations for food and nutrient intake are not intended to be met every day but rather on average over a span of time. Although the 2010 dietary intake objectives address the proportion of the population that consumes a specified level of certain foods or nutrients, it is also important to track and report the average amount eaten by different population groups to help interpret progress on these objectives. Other objectives target aspects of undernutrition, including iron deficiency, growth retardation, and food security.
In summary, several actions are recognized as fundamental in achieving the 2010 objectives:
•	Improving accessibility of nutrition information, nutrition education, nutrition counseling and related services, and healthful foods in a variety of settings and for all subpopulations.
•	Focusing on preventing chronic disease associated with diet and weight, beginning in youth.
•	Strengthening the link between nutrition and physical activity in health promotion.
•	Maintaining a strong national program for basic and applied nutrition research to provide a sound science base for dietary recommendations and effective interventions.
•	Maintaining a strong national nutrition monitoring program to provide accurate, reliable, timely, and comparable data to assess status and progress and to be responsive to unmet data needs and emerging issues.
•	Strengthening State and community data systems to be responsive to the data users at these levels.
•	Building and sustaining broad-based initiatives and commitment to these objectives by public and private sector partners at the national, State, and local levels.
Interim Progress Toward Year 2000 Objectives
Of the 27 nutrition objectives, targets for 5 have been met, including 2 related to the availability of reduced-fat foods and prevalence of growth retardation.^9, ^28 The majority of the objectives have shown some progress, including those related to total fruit, vegetable, and grain product intake and total fat and saturated fat intake; availability of nutrition labeling on foods; breastfeeding; nutrition education in schools; and availability of worksite nutrition and weight management programs. For certain other objectives, such as consumer actions to reduce salt intake and home-delivered meals to elderly persons, there has been little or no progress. And for others, such as intake of calcium-rich food and overweight and obesity, movement has been away from the targets. In particular, the proportion of adults and children who are overweight or obese has increased substantially, and this represents one of the biggest challenges for Healthy People 2010.

Maintenance of a healthy weight is a major goal in the effort to reduce the burden of illness and its consequent reduction in quality of life and life expectancy. The selection of a BMI cut-point to establish the upper limit of the healthy weight range is based on the relationship of overweight or obesity to risk factors for chronic disease or premature death. A BMI of less than 25 has been accepted by numerous groups as the upper limit of the healthy weight range, since chronic disease risk increases in most populations at or above this cut-point.^14, ^15, ^29 The lower cut-point for the healthy weight range (BMI of 18.5) was selected to be consistent with national and international recommendations.^14, ^15 Problems associated with excessive thinness (BMI less than 18.5) include menstrual irregularity, infertility, and osteoporosis. There is some concern that the increased focus on overweight may result in more eating disorders, such as bulimia and anorexia nervosa. (See Focus Area 18. Mental Health and Mental Disorders.) However, no evidence currently exists that suggests the increased focus on overweight has resulted in additional cases of eating disorders.
Overweight and obesity are caused by many factors. These factors reflect the contributions of inherited, metabolic, behavioral, environmental, cultural, and socioeconomic components. As weight increases, so does the prevalence of health risks. Simple, health-oriented definitions of overweight and obesity should be based on the amount of excess body fat at which health risks to individuals begin to increase. No such definitions currently exist. Most current clinical studies assessing the health effects of overweight rely on a measurement of body weight adjusted for height. BMI is the choice for many researchers and health professionals. While the relation of BMI to body fat differs by age and gender, it provides valid comparisons across racial and ethnic groups.^29 However, BMI does not provide information concerning body fat distribution, which has been identified as an independent predictor of health risk.^30 Thus, until a better surrogate for body fat is developed, BMI will be used to screen for overweight and obese individuals.
Interpretations of data about overweight and obesity have differed because criteria for these terms have varied over time, from study to study, and from one part of the world to another. National and international organizations now support the use of a BMI of 30 or greater to identify obesity.^14, ^15 These BMI cut-points are only a guide to the identification and treatment of overweight and obese individuals and allow for the comparison across populations and over time. However, the health risks associated with overweight and obesity are part of a continuum and do not conform to rigid cut-points.
Overweight and obesity affect a large proportion of the U.S. population—55 percent of adults. Over two decades, the number of cases of obesity alone has increased more than 50 percent—from 14.5 percent of the adult population to 22.5 percent. Approximately 25 percent of U.S. adult females and 20 percent of U.S. adult males are obese.^12 Since weight management is difficult for most persons, the 2010 target of no more than 15 percent of adults aged 20 years and older having a BMI of 30 or more is ambitious. Nonetheless, the potential benefits from reduction in overweight and obesity are of considerable public health importance and deserve particular emphasis and attention. A concerted public effort will be needed to prevent further increases of overweight and obesity. Health care providers, health plans, and managed care organizations need to be alert to the development of overweight and obesity in their clients and should provide information concerning the associated risks. These groups need to provide guidance to help consumers address this health problem. To lose weight and keep it off, overweight persons will need long-term lifestyle changes in dietary and physical activity patterns that they can easily incorporate into their lives.
Patterns of healthful eating behavior need to begin in childhood and be maintained throughout adulthood. These patterns can be encouraged through nutrition education at schools and worksites that takes into account cultural and other factors influencing diet. Persons should be aware of the impact that away-from-home eating can have on weight management. In order to address physical activity needs, changes in the physical environment—such as access to walkways and bicycle paths—and the social environment—through social support and safe communities—will be needed to achieve long-term success.
There is much concern about the increasing prevalence of obesity in children and adolescents. Overweight and obesity acquired during childhood or adolescence may persist into adulthood and increase the risk for some chronic diseases later in life. Teenaged boys lose some fat accumulated before puberty during adolescence, but fat deposition continues in girls. Thus, without measures of sexual maturity, measures of body fat and body weight are difficult to interpret in preadolescents and adolescents. Therefore, the objective to reduce the prevalence of overweight and obesity among children and adolescents has a target set at no more than 5 percent and uses the gender- and age-specific 95th percentile of BMI from the year 2000 National Center for Health Statistics/Centers for Disease Control and Prevention (NCHS/CDC) growth charts. Interventions need to recognize that obese children also may experience psychological stress. The reduction of BMI in children and adolescents should be achieved by emphasizing physical activity and a properly balanced diet so that healthy growth is maintained. Additional research is needed to better define the prevalence and health consequences of overweight and obesity in children and adolescents and the implications of such findings for these persons as they become the next generation of adults.

Retardation in linear growth in preschool children serves as an indicator of overall health and development and also may reflect the adequacy of a child’s diet. Full growth potential may not be reached because of less than optimal nutrition, infectious diseases, chronic diseases, or poor health care. Inadequate maternal weight gain during pregnancy and other prenatal factors that influence birth weight also affect the prevalance of growth retardation among infants and young children.
Growth retardation is not a problem for the majority of young children in the United States. By definition, approximately 5 percent of healthy children are expected to be below the fifth percentile of height for age due to normal biologic variation. If more than 5 percent of a population group is below the fifth percentile, this suggests that full growth potential is not being reached by some children in that group. Among some age and ethnic groups of low-income children under age 5 years in the United States, up to 15 percent are below the fifth percentile. While progress has been made in reducing the prevalence of growth retardation among low-income Hispanic and Asian or Pacific Islander children, it remains especially high for African American children in the first year of life.
Interventions to improve children’s linear growth potential include better nutrition; improvements in the prevention, diagnosis, and treatment of infectious and chronic diseases; and provision and use of adequate health services. Although the response of a population to interventions for growth retardation may not be as rapid as for iron deficiency or underweight, achievement of the objective by the year 2010 in all racial and ethnic, socioeconomic, and age subgroups should be possible. Special attention should be given to homeless children and those with special health care needs.

The 1995 Dietary Guidelines for Americans recommend that Americans choose a diet with plenty of grain products, vegetables, and fruits, which is also low in fat, saturated fat, and cholesterol and moderate in salt, sodium, and sugars.^6 Many Americans of all ages eat fewer than the recommended number of servings of grain products, vegetables, and fruits.^28 Vegetables (including legumes, such as beans and peas), fruits, and grains are good sources of complex carbohydrates (starch and dietary fiber), vitamins and minerals, and other substances that are important for good health. Some evidence from clinical studies suggests that water-soluble fibers from foods such as oat bran, beans, and certain fruits are associated with lower blood glucose and blood lipid levels.^32 Dietary patterns with higher intakes of vegetables (including legumes), fruits, and grains are associated with a variety of health benefits, including a decreased risk for some types of cancer.^32, ^33, ^34, ^35, ^36, ^37
The 1995 Dietary Guidelines for Americans recommend three to five servings from various vegetables and vegetable juices and two to four servings from various fruits and fruit juices, depending on calorie needs. Consumers can select from a plentiful supply of fresh, frozen, and canned products throughout the year. The Dietary Guidelines for Americans recommend that Americans choose dark green leafy and deep yellow vegetables and legumes often and prepare and serve vegetables with limited fat. In 1994-96, the average daily intake of fruits and vegetables was five servings, but only about 8 percent of vegetable servings were dark green or deep yellow, and only about 5 to 6 percent were legumes.^38 In contrast, fried potatoes accounted for about one-third (32 percent) of vegetable servings consumed by youth aged 2 to 19 years. Consumption of fruits and vegetables also is tracked at the State level and is discussed in Tracking Healthy People 2010.
The 1995 Dietary Guidelines for Americans recommend 6 to 11 daily servings of grain products, depending on calorie needs, with several of these from whole-grain breads and cereals. Although grain product consumption increased during the 1990s, consumption of whole-grain products remains very low. In 1994-96, for the population aged 2 years and older, the average daily intake of grain products was nearly seven servings, but only about 14 to 15 percent of grain servings were whole grain.^38 The guidelines also recommend that grain products be prepared with little or no fats and sugars; however, considerable amounts of fats and sugars are contributed to American diets by baked products such as cookies, cakes, and doughnuts.^39, ^40 No State-level data on grain intakes are available for adults, adolescents, and children.

Both the Dietary Guidelines for Americans and the National Cholesterol Education and Prevention Program recommend a diet that contains less than 10 percent of calories from saturated fat and no more than 30 percent of calories from total fat.^6, ^33, ^41 This can be achieved by emphasizing foods from the grain products group, along with vegetables and fruits. Such a healthful diet also can include low-fat and lean foods from the milk group and the meat group. The increase of overweight and obesity in America indicates that more attention needs to be paid to serving size and total calorie content because a low-fat content does not, automatically, signify a lower calorie content.
The role of fat in the diet is complicated because different types of fatty acids have different effects on health. Evidence to date is complicated, but certain messages appear clear: Americans consume too much dietary fat in general, and too much of the fat consumed is from saturated fatty acids—the type associated with an increased risk for heart disease.
Strong evidence from human and animal studies shows that diets low in saturated fatty acids and cholesterol are associated with low risks and rates of coronary heart disease. Saturated fatty acids are the major dietary factors that raise blood LDL-cholesterol levels, increasing the risk for heart disease. Increasing evidence suggests that trans-fatty acids can also increase LDL-cholesterol levels, although less than saturated fatty acids.^42 Monounsaturated and polyunsaturated fatty acids do not raise blood cholesterol. Omega-3 polyunsaturated fatty acids found in many ocean fish appear to lower triglyceride levels but may cause a concurrent rise in LDL-cholesterol levels,^43 especially in persons with hypertriglyceridemia.
A 1989 National Research Council report^33 indicated that diets high in total fat were associated with a higher risk of several cancers, especially cancer of the colon, prostate, and breast, but noted that findings were inconsistent. A 1996 review of the evidence showed that the relationship between the amount and type of fat and the risk of cancer continues to be uncertain.^44 To help clarify the relationship between total dietary fat and the risk of cancer, a randomized clinical trial called the Women’s Health Initiative has been started. Set to conclude in 2003, it is a multicenter trial designed to test several risk factors for chronic disease in U.S. females.^45 A major emphasis is to reduce fat to 25 percent of dietary calories to determine whether a low-fat diet has any effect on breast cancer risk.
The proportion of calories in the U.S. diet provided by total fat is about 33 percent, saturated fat is about 11 percent, and trans-fat is about 2.6 percent.^46 The primary sources of saturated fat are meats and dairy products that contain fat. Thus, nonfat and low-fat dairy products and lean meats are choices that can help reduce saturated fat intake. Trans-fatty acids are formed when vegetable oil is hydrogenated to become the major ingredient in margarine or shortening. Trans-fat-free margarines are available in most U.S. grocery stores. Other dietary sources of trans-fat are restaurant and fast-food fats, including frying fats; baked products, especially sweet bakery items; and some snack foods, such as chips.
The major vegetable sources of monounsaturated fatty acids include nuts, avocados, olive oil, canola oil, and high-oleic forms of safflower and sunflower seed oil. The major sources of polyunsaturated fatty acids are vegetable oils, including soybean oil, corn oil, and high-linoleic forms of safflower and sunflower seed oil and a few nuts, such as walnuts. Substituting monounsaturated and polyunsaturated fatty acids for saturated fatty acids can help lower health risks.
The proportion of all meals and snacks from away-from-home sources increased by more than two-thirds between 1977-78 and 1995, from 16 percent of all meals and snacks in 1977-78 to 27 percent of all meals and snacks in 1995.^27 Away-from-home food tends to have a higher saturated fat content, and persons tend to consume more calories when eating away from home than at home.^27 In 1995, the average total fat and saturated fat content of away-from-home foods, expressed as a percentage of calories, was 38 percent and 13 percent, respectively, compared with 32 percent and 11 percent for at-home foods.^27 Meals and snacks eaten by children at school had the highest saturated fat density of all food outlets. Thus, to help assess fat and saturated fat intake, as well as develop strategies to help children reduce the amount of fat they consume, the additional tracking of saturated fat and total fat intake from foods eaten away from home as well as at home is important.

The 1995 Dietary Guidelines for Americans recommend choosing a diet moderate in salt and sodium (salt consists of both sodium and chloride). Most studies in diverse populations have shown that salt intake is linked to increasing levels of blood pressure.^6, ^47, ^48, ^49 Persons who consume less salt or sodium have a lower risk of developing high blood pressure.^6 Data also show that high sodium intake may increase the amount of calcium excreted in the urine and therefore increase the body’s need for calcium.^50
Most Americans consume more sodium than is needed, and reduction of sodium or salt or both to no more than 2,400 mg sodium or 6 g salt per day is recommended by some authorities.^33, ^47 Data from the Continuing Survey of Food Intakes by Individuals show that, even without including salt added at the table, both home foods and away-from-home foods provide excessive amounts of sodium.^27 Higher sodium intakes also tend to be associated with higher calorie intakes; for example, males, who consume more calories than females, also consume more sodium.^27
Sodium occurs naturally in foods. However, most dietary salt or sodium is added to foods during processing or preparation, with smaller amounts added at the discretion of the consumer in the form of table salt or use of condiments such as soy sauce.^51, ^52 Thus, in assessing dietary sodium consumption, both the sodium content of foods and estimates of the amount of salt added have been used. Other contributing sources of sodium are water, dietary supplements, and medications such as antacids.

Calcium is essential for the formation and maintenance of bones and teeth.^32 The recommendations for adequate daily intakes of calcium are 500 mg for children aged 1 to 3 years, 800 mg for children aged 4 to 8 years, 1,300 mg for adolescents aged 9 to 18 years, 1,000 mg for adults aged 19 to 50 years, and 1,200 mg for adults aged 51 years and older.^53 Approximated mean calcium requirements are defined as 77 percent of the recommendations by the Institute of Medicine for adequate intakes of calcium.^53, ^54 The bone mass achieved at full growth (peak bone mass) appears to be related to intake of calcium during childhood and adolescence.^33 Opinion is divided as to the age at which peak bone mass is achieved, although most of the accumulation of bone mineral occurs in humans by about age 20 years. After persons reach their adult height, a period of consolidation of bone density continues until approximately age 30 to 35 years. A high peak bone mass is thought to be protective against fractures in later life.
Osteoporosis is a complex disorder caused by many contributing factors. (See Focus Area 2. Arthritis, Osteoporosis, and Chronic Back Conditions.) Regular exercise and a diet with enough calcium help maintain good bone health and reduce the risk of osteoporosis later in life. However, the ideal level of calcium intake for development of peak bone mass is unknown. For the most part, young children appear to meet the approximate calcium requirements. In contrast, the majority of adolescent and adult females do not meet the average requirements. This is in part because of their lower food consumption, as well as the lower consumption of milk products relative to soft drinks in American diets. ^55 For example, in the period 1994 to 1996, the amount of soft drinks consumed was about twice that consumed in the late 1970s and surpassed consumption of fluid milk. Thus an increase in consumption of various sources of calcium is recommended for nearly all groups and especially for teenaged girls and women. In postmenopausal females—the group at highest risk for osteoporosis—estrogen replacement therapy under medical supervision is the most effective means to reduce the rate of bone loss and risk of fractures.^32
The relationship between dietary calcium and blood pressure is uncertain. Results from studies that have used calcium supplements show a small reduction in systolic blood pressure in hypertensive individuals, with no significant reduction in diastolic blood pressure.^56 Among persons with normal blood pressure, there is no significant difference in blood pressure with calcium supplements.^57
Dietary sources of calcium include milk and milk products such as cheese and yogurt, canned fish with soft bones such as sardines, dark green leafy vegetables such as kale and mustard or turnip greens, tofu made with calcium, tortillas made from lime-processed corn, calcium-enriched grain products, and other calcium-fortified foods and beverages.^6 In some locations, water is a source of calcium, but in amounts that cannot readily be determined. With current food selection practices, use of dairy products may constitute the difference between getting enough calcium in one’s diet or not. Nonfat and low-fat dairy products are choices that help reduce the intake of saturated fat while still providing calcium, vitamin D, and other nutrients important for bone health. For those who have lactose intolerance, there is a range of lactose-reduced dairy products that provide calcium. Persons who do not (or cannot) consume and absorb adequate levels of calcium from dairy food sources may consider use of calcium-fortified foods, while those with clinical evidence of inadequate intake should receive professional advice on the proper type and dosage of calcium supplements. Calcium supplements come in different forms, including calcium-containing antacids.
Fluid milk (but not yogurt or cheese) is an excellent source of vitamin D, which is essential for calcium utilization. Vitamin D also is synthesized in the skin upon exposure to sunlight.

The terms anemia, iron deficiency, and iron deficiency anemia often are used interchangeably, but are not equivalent. Iron deficiency ranges from depleted iron stores without functional or health impairment to iron deficiency with anemia, which affects the functioning of several organ systems. Iron deficiency anemia is more likely than iron deficiency without anemia to cause preterm births, low birth weight, and delays in infant and child development.^58, ^59, ^60 Iron deficiency (with and without anemia) in adolescent females has been associated with decreased verbal learning and memory.^61 The prevalence of iron deficiency anemia among children aged 1 to 2 years and 3 to 4 years and females aged 12 to 49 years in 1988 to 1994 was 3 percent, less than 1 percent, and 4 percent, respectively.
Anemia can be caused by many factors other than iron deficiency, including other nutrient deficiencies, infection, inflammation, and hereditary anemias. Anemia is used for monitoring risk of iron deficiency at the State and local levels because of the low cost and feasibility of measuring hemoglobin or hematocrit in the clinic setting.^62 Anemia is a good predictor of iron deficiency when the prevalence of iron deficiency is high, such as during the third trimester of pregnancy. It is not a good predictor of iron deficiency when the prevalence of iron deficiency is expected to be low, such as among white, non-Hispanic children aged 3 to 4 years in the United States. In that case, the majority of anemia is due to other causes.^8 However, changes in the prevalence of anemia over time at State and local levels can be used to evaluate the effectiveness of programs to decrease the prevalence of iron deficiency.
Iron deficiency and anemia among young children declined during the 1970s in association with increased iron intake.^8 Although the prevalence of iron deficiency among low-income children continued to decline from 1976-80 to 1988-94, the prevalence of iron deficiency among all young children remained the same, and the prevalence of iron deficiency among females of childbearing age actually increased.^9 From 1979 to 1996, the prevalence of third trimester anemia among low-income pregnant females did not change.^63, ^64
Iron deficiency is highest among toddlers and among minority and low-income children.^65 Iron deficiency can be prevented among young children by teaching families about child nutrition, including promoting breastfeeding of infants, with exclusive breastfeeding for 4 to 6 months, the use of iron-fortified formulas when formulas are used; delayed introduction of cow’s milk until 12 months of age; and age-appropriate introduction of iron-rich solid foods, such as iron-fortified infant cereals and pureed meats and introduction of foods that enhance iron absorption such as vitamin C-rich fruits, vegetables, or juices.^62
Nonpregnant females of childbearing age are at increased risk for iron deficiency because of iron loss during menstruation coupled with inadequate intake of iron.^62 Pregnant females are also at increased risk because of the increased iron requirements of pregnancy.^62, ^64 Consequently, an objective has been established to reduce the prevalence of anemia among low-income pregnant females in their third trimester. Although groups other than low-income females are considered at risk for iron deficiency during pregnancy, there are no nationally representative data on the prevalence of iron deficiency or iron deficiency anemia among pregnant females.
National data indicate that only one-fourth of all females of childbearing age (12 to 49 years) meet the U.S. recommended dietary allowance for iron (15 mg) through their diets.^66 Iron deficiency among females of childbearing age may be prevented by periodic anemia screening and appropriate treatment and by counseling them about better eating practices, such as selecting iron-rich foods, taking iron supplements during pregnancy, increasing consumption of foods that enhance iron absorption (for example, orange juice and other citrus products), and discouraging consumption of iron inhibitors (for example, coffee and tea) with iron-rich foods.^62 Some good sources of iron include meats, poultry, fish, leafy greens of the cabbage family, legumes, dry beans and peas, yeast-leavened whole wheat bread and rolls, and iron-enriched white bread, pasta, rice, and cereals.^6
Schools, Worksites, and Nutrition Counseling
19-15.	(Developmental) Increase the proportion of children and adolescents aged 6 to 19 years whose intake of meals and snacks at schools contributes proportionally to good 
overall dietary quality.
Potential data source: Continuing Survey of Food Intakes by Individuals (CSFII), USDA.
Students today have increased food options at school. Although students may understand that good nutrition and good health are connected, that understanding may not be reflected in their food choices and meal patterns. The U.S. Department of Agriculture (USDA) has established standards requiring schools to plan menus that meet the Dietary Guidelines for Americans, but these standards do not apply to à la carte foods; to foods sold in snack bars, school stores, and vending machines; or to foods students bring from home. Students’ food choices are influenced by the total eating environment created by schools. This includes the types of foods available throughout the school, point-of-choice nutrition information in the cafeteria and around the school, nutrition education provided in the classroom, and nutrition promotions that reach families and affect the choices of foods brought to school.
Improving the quality of students’ dietary intake in the school setting is important because, for many children, meals and snacks consumed at school make a major contribution to their total day’s consumption of food and nutrients. National food consumption data collected in 1994 and 1995 show that meals and snacks consumed at schools had the highest saturated fat density of all food outlets.^27 School foods also had higher than recommended levels of sodium—as did other away-from-home foods and at-home foods. Nonetheless, these analyses also showed positive aspects of foods obtained from school. School foods had the highest calcium density of all sources and the highest dietary fiber density of all away-from-home sources. The establishment of an environment that supports a good overall diet would enable school nutrition and food services, in conjunction with students, their families, and other school employees, to make an important contribution to short- and long-term disease prevention and health promotion. In addition, such an environment would foster learning readiness (for example, by encouraging students to consume substantial breakfasts).^67, ^68, ^69
19-16. 	Increase the proportion of worksites that offer nutrition 
or weight management classes or counseling.
Target: 85 percent.
Baseline: 55 percent of worksites with 50 or more employees offered nutrition or weight management classes or counseling at the worksite or through their health plans in 1998-99. 
Target setting method: 55 percent improvement.

Worksite programs can reach large numbers of employees with information, activities, and services that encourage the adoption of healthy dietary and physical activity behaviors.^70 Employer-sponsored programs can be offered onsite or in partnership with community organizations. Examples of such programs include weight management classes, physical activity programs, lunchtime seminars, self-help programs, cooking demonstrations and classes, healthy food service and vending machine selections, point-of-purchase nutrition information, and flexible health benefits that include nutrition-related services.
A recent study of worksite health promotion programs found that specific interventions at the worksite resulted in employees choosing to reduce the amount of fat calories they consumed and eating more fruits, vegetables, and dietary fiber.^71 Worksite health promotion programs may reduce health care costs, including employer costs for insurance programs, disability benefits, and medical expenses.^72, ^73
If possible, nutrition education and weight management programs at the worksite should be part of a comprehensive health promotion program. In addition, employers could reimburse health promotion activities and provide company time for employees to participate in the programs.^74
Worksite programs should be made available to the family members of employees and company retirees, as well as current employees. Also, these programs should be offered in a culturally and linguistically competent manner and any education materials provided should be culturally and linguistically appropriate.
19-17. 	Increase the proportion of physician office visits made 
by patients with a diagnosis of cardiovascular disease, diabetes, or hyperlipidemia that include counseling or education related to diet and nutrition.
Target: 75 percent.
Baseline: Counseling or education on diet and nutrition was ordered or provided for 42 percent of physician office visits that were related to the diagnosis of cardiovascular disease, diabetes, or hyperlipidemia in 1997 (age adjusted to the year 2000 standard population).

Primary care providers are well positioned in the health care system to provide preventive services, including nutrition screening and assessment, referral, and counseling. For example, they can screen for age-specific and diagnosis-related nutrition risk factors as a part of routine patient contact. The public views physicians—and registered dietitians in particular—as credible sources of nutrition information.^75 Dietary assessment, counseling, and followup by physicians and qualified nutrition professionals are effective in reducing patient dietary fat intake and serum cholesterol.^76, ^77, ^78, ^79 For many physicians, referring patients to qualified nutrition professionals for nutrition assessment, education, counseling on behavioral change, diet modification, and specialized nutrition therapies represents appropriate clinical practice.
Nutrition counseling by registered dietitians and other qualified nutrition professionals has been found to be cost effective for patients with hyperlipidemia^80, ^81 and type 2 diabetes mellitus.^82 Nutrition services also are a critical component of improved health outcomes for many other diseases and conditions, including obesity, gastrointestinal and hepatic disease, renal disease, cancer, HIV/AIDS, pressure ulcers, burns and trauma, eating disorders, and prenatal care. A 1997 study that evaluated the cost of covering medical nutrition therapy under Medicare part B projected savings to the program of $11 million in 2001 and $65 million in 2004.^83, ^84

Food security means that people have access at all times to enough food for an active, healthy life. It implies that people have nutritionally adequate and safe foods and sufficient household resources to ensure their ability to acquire adequate, acceptable foods in socially acceptable ways—that is, through regular marketplace sources and not through severe coping strategies like emergency food sources, scavenging, and stealing. Hunger in this context refers to the uneasy or painful sensation caused by a lack of food.
While the vast majority of Americans are food secure and have not experienced hunger, both food insecurity and hunger have remained a painful fact of life for too many Americans.^85, ^86 The specific concern is with food insecurity and hunger resulting from inadequate household resources. Other sources of food insecurity (such as illness, child abuse and neglect, or loss of function or mobility) are not included in this definition. Food insecurity and hunger may coexist with malnutrition, but they are not the same thing nor even necessarily closely associated. Food insecurity and hunger, however, are believed to have harmful health and behavioral impacts in their own right.^87 These are of particular concern for pregnant women, children, elderly persons, and other nutritionally vulnerable groups.^88
The United States is committed to increasing food security by working with local leaders as outlined in the U.S. Action Plan on Food Security, through USDA’s Community Food Security Initiative, and the Maternal and Child Health Bureau’s Healthy Start.^89, ^90

Terminology
(A listing of all abbreviations and acronyms used in this publication appears in Appendix K.)
Anemia: A condition in which the hemoglobin in red blood cells falls below normal. Anemia most often results from iron deficiency, but also may result from deficiencies of folic acid, vitamin B12, or copper, or from chronic disease, certain conditions, or chronic blood loss.
Body mass index (BMI): Weight (in kilograms) divided by the square of height (in meters), or weight (in pounds) divided by the square of height (in inches) times 704.5. Because it is readily calculated, BMI is the measurement of choice as an indicator of healthy weight, overweight, and obesity.
Calorie: Unit used for measuring the energy produced by food when metabolized in the body.
Cholesterol: A waxy substance that circulates in the bloodstream. When the level of cholesterol in the blood is too high, some of the cholesterol is deposited in the walls of the blood vessels. Over time, these deposits can build up until they narrow the blood vessels, causing atherosclerosis, which reduces the blood flow. The higher the blood cholesterol level, the greater is the risk of getting heart disease. Blood cholesterol levels of less than 200 mg/dL are considered desirable. Levels of 240 mg/dL or above are considered high and require further testing and possible intervention. Levels of 200-239 mg/dL are considered borderline. Lowering blood cholesterol reduces the risk of heart disease.
HDL (high-density lipoprotein) cholesterol: The so-called good cholesterol. Cholesterol travels in the blood combined with protein in packages called lipoproteins. HDL is thought to carry cholesterol away from other parts of the body back to the liver for removal from the body. A low level of HDL increases the risk for CHD, whereas a high HDL level is protective.
LDL (low-density lipoprotein) cholesterol: The so-called bad cholesterol. LDL contains most of the cholesterol in the blood and carries it to the tissues and organs of the body, including the arteries. Cholesterol from LDL is the main source of damaging buildup and blockage in the arteries. The higher the level of LDL in the blood, the greater is the risk for CHD.
Complex carbohydrate: Starch and dietary fiber.
Coronary heart disease (CHD): The type of heart disease due to narrowing of the coronary arteries.
Dietary fiber: Plant food components, including plant cell walls, pectins, gums, and brans that cannot be digested.
Dietary Guidelines for Americans: A report published by the U.S. Department of Agriculture and U.S. Department of Health and Human Services that explains how to eat to maintain health. The guidelines form the basis of national nutrition policy and are revised every 5 years. This chapter refers to the 1995 guidelines.
Fats/fatty acids: Fats and fatty acids are hydrocarbon chains ending in a carboxyl group at one end that bond to glycerol to form fat. Fatty acids are characterized as saturated, monounsaturated, or polyunsaturated depending on how many double bonds are between the carbon atoms. Fatty acids supply energy and promote absorption of fat-soluble vitamins. Some fatty acids are Aessential,” because they cannot be made by the body.
Saturated fatty acids: Fatty acids with no double bonds between carbon atoms. Levels of saturated fatty acids are especially high in meat and dairy products that contain fat. Saturated fatty acids are linked to increased blood cholesterol levels and a greater risk for heart disease.
Trans-fatty acids: Alternate forms of naturally occurring unsaturated fatty acids produced in fats as a result of hydrogenation, such as when vegetable oil becomes margarine or shortening. Trans-fatty acids also occur in milk fat, beef fat, and lamb fat. These fatty acids have been associated with increased blood cholesterol levels.
Unsaturated fatty acids: Fatty acids with one or more double bonds between carbon atoms. These fatty acids do not raise blood cholesterol levels.
Polyunsaturated: Fatty acids with more than one double bond between carbon atoms.
Monounsaturated: Fatty acids with one double bond between carbon atoms.
Food Guide Pyramid: A graphic depiction of USDA’s current food guide that includes five major food groups in its Abase” (grains, vegetables, fruits, milk products, meat, and meat substitutes) and a Atip” depicting the relatively small contribution that discretionary fat and added sugars should make in American diets. The Food Guide Pyramid provides information on the choices within each group and the recommended number of servings.
Food security: Access by all people at all times to enough food for an active, healthy life. It includes at a minimum (1) the ready availability of nutritionally adequate and safe foods, and (2) an assured ability to acquire acceptable foods in socially acceptable ways.
Food insecurity: Limited or uncertain availability of nutritionally adequate and safe foods or limited and uncertain ability to acquire acceptable foods in socially acceptable ways.
HDL-cholesterol: See cholesterol.
Hunger: The uneasy or painful sensation caused by a lack of food.
Hypertension: High blood pressure.
Hypertriglyceridemia: Elevated levels of triglycerides in the blood.
Linear growth: Increase in length or height.
Iron deficiency: Lack of adequate iron in the body to support and maintain functioning. It can lead to iron deficiency anemia, a reduction in the concentration of hemoglobin in the red blood cells due to a lack of iron supply to the bone marrow.
LDL-cholesterol: See cholesterol.
Medical nutrition therapy: Use of specific nutrition counseling and interventions, based on an assessment of nutritional status, to manage a condition or treat an illness or injury. 
Metabolism: The sum total of all the chemical reactions that go on in living cells.
Nutrition: The set of processes by which nutrients and other food components are taken in by the body and used.
Obesity: A condition characterized by excessive body fat.
Osteoporosis: A bone disease characterized by a reduction in bone mass and a deterioration of the bone structure leading to bone fragility.
Overweight: Excess body weight.
Physical activity: Bodily movement that substantially increases energy expenditure.
Registered dietitian: A food and nutrition expert who has met the minimum academic and professional requirements to receive the credential ARD.” Many States and Commonwealths also have licensing laws for dietitians and nutrition practitioners.
Sedentary behavior: A pattern of behavior that is relatively inactive, such as a lifestyle characterized by a lot of sitting.
Type 2 diabetes: The most common form of diabetes, which results from insulin resistance and abnormal insulin action. Type 2 diabetes was previously referred to as non-insulin-dependent diabetes mellitus (NIDDM) and adult-onset diabetes.
