Introduction Chapter provides a broad examination of
food and nutrient intakes by the U.S population, the food and eating environment, prevalence of chronic health conditions.
Provides an understanding of the relationship of food intake and the food environment to nutrition-related health conditions. Documents high rates of diet-related health conditions and provides compelling reasons to study them in greater detail. Provides context for actions to facilitate and implement behavior change and adoption of healthy eating practices in the U.S. population.
Taken together, our analyses inform the remaining chapters in the report, which will provide the contextual and scientific foundation for the 2015
Dietary Guidelines for Americans.

Nutrient Intakes and Nutrients of Concern
Based on intake data, together with nutritional biomarker and health outcomes data, identified nutrients that may pose a public health concern:
Vitamin D, calcium, potassium, and fiber are underconsumed across the entire US population. Iron is underconsumed for adolescent and premenopausal females. Sodium is overconsumed across the entire US population Saturated fat is overconsumed and may pose the greatest risk to those > 50 years old.
Cholesterol is not considered a nutrient of concern for overconsumption.

Nutrient IntakesSupplements, Caffeine
Overconsumption of nutrients from foods and beverages, including fortified foods, is rare.
However, folate, calcium, iron, and vitamin D may be overconsumed in some supplement users, especially those taking high-dose supplements.
In general, caffeine intakes do not exceed what are currently considered safe levels for any age group.

Adequacy of the USDA Food Patterns USDA Food Patterns provide food-based guidance. The Patterns meet nutrient adequacy goals across a broad range of age and energy levels.
When adjusted for the food choices of young children, Patterns meet their nutrient needs.
Patterns do not meet recommendations for potassium (AI) and vitamin D (RDA).
Additional fortification or supplementation strategies may be needed to reach RDA levels for vitamin D intake.
Recommended amounts of food groups and their component subgroups fall within the broad range of usual food group intakes for the U.S. population.

Food groupsCurrent Intakes
Food groups include fruits, vegetables, grains, dairy, and protein foods, and are based on the USDA Food Pattern classification. Limits for solid fats and added sugars (empty calories) are also part of the patterns.
Across all age and sex groups, the vast majority of the U.S. population does not meet recommended intakes for fruit, vegetables, whole grains, and dairy food groups.
Across all age and sex groups, the vast majority of the U.S. population exceeds recommended intakes of refined grains, solid fats, and added sugars.
Many young children consume recommended amounts of fruit and dairy foods, but these intakes drop as children reach school age and beyond.

Eating BehaviorsMeals and Snacks The majority of the U.S. population consumes three meals a day plus at least one snack.
Children ages 2-5 yearsmost likely to consume three meals a day.
Adolescent females, young adult males, non-Hispanic Blacks, Hispanics, and individuals with lower incomesleast likely toconsume three meals a day.
Breakfast tends to have a higher overall dietary quality compared to other meals and snacks. Adolescents andyoung adults are the least likely to eat breakfast. Snacks contribute about one-fourth of daily energy intakeand are lower in nutrients of concern relative to energy intake than are meals.

Eating BehaviorsL ocation of Purchase About two-thirds of the calories consumed by the U.S. population are purchased at a store, such as a grocery store or supermarket, and consumed in the home.
The percent of calories eaten away from home has remained about the same since 2003-2004.
Food group content and nutrient quality vary by where food is obtained.
No matter where the food is obtained, diet quality of the U.S. population is low in fruit, vegetables, dairy, whole grains, and high in sodium, saturated fats, refined grains, solid fats, and added sugars.

Health ConditionsOverweight and Obesity
Current rates of overweight and obesity are extremely high among children, adolescents, and adults. These high rates have persisted for more than 25 years.
About 65% of adult females and 70% of adult males are overweight or obese. Rates of overweight and obesity are highest in adults 40+ years, and vary by race/ethnicity.
Abdominal obesity is present in U.S. adults of all ages, increases with age, and varies by sex and race/ethnicity. Nearly one in three youth, ages 2 to 19 years, is now overweight or obese and these rates vary by age and ethnicity.

Health Conditions
At all ages, rates of chronic disease are linked to overweight and obesity . Adults have high rates of high blood pressure, CVD, diabetes, and various forms of cancer . Children and adolescents also have nutrition-related chronic diseases, including borderline high blood pressure and type2 diabetes. Prevalence of osteoporosis and of low bone mass increases with age, particularly in post-menopausal women. Nutrition-related neurological and psychological conditions are a growing concern. Congenital anomalies are a relatively rare, but important pregnancy outcome.

Dietary Patterns Composition Dietary patterns observed to have health benefits in intervention and cohort studies had certain common elements.
A healthful diet can be achieved by following a variety of dietary patterns.
In many cases, the ranges of intake in dietary patterns with positive health benefits are close to those recommended by the USDA Food Patterns.
The data from the intervention trials and the cohort studies examined provide empirical data that the USDA Food Patterns provide an evidence-based guide to healthy patterns of food consumption.

Chapter Summary The US population has low intakes of certain key nutrients vitamin D, potassium, fiber, calcium, and for females also iron. These low intakes are a public health concern because inadequate intakes are linked to health problems.
The US population overconsumes sodium and saturated fat. Excess intakes of these nutrients are also linked to health problems.
Many of the food groups that are good sources of underconsumed nutrients are consumed in low amounts by the U.S. population.
Many of the food groups and food categories that have high levels of sodium, saturated fat, and added sugars are consumed in high amounts.

Chapter Summary
The US population purchases and consumes food in a variety of locations.
The diet quality is low regardless of where food is
purchased or consumed.
Rates of diet-related chronic conditions are high. Obesity, CVD, CVD risk factors, diabetes, cancer, and osteoporosis are all very common. Improving diet quality will help reduce risk of these diseases with major morbidity, mortality and health care expenditures.

Research Recommendations
Nutrition Surveillance, NHANES/WWEIA needs more respondents from a variety of racial/ethnic minority groups, more non-U.S. born residents and increase the number of pregnant women and older Americans - all of these groups are currently under-represented.
Research is needed to understand the driving forces
behind the decline in diet quality that begins in mid childhood, through adolescence, through adulthood.
Improvements are needed in the quantity and quality of food composition databases.

2015 DGAC: MEETING 7
Research Recommendations Investigate the validity, reliability and reproducibility of new biomakers of dietary intake and nutritional status. Evaluate the effects of fortification and supplement use on consumer behavior related to intakes of nutrients of public health concern. Understand the health effects from high-dose dietary supplements. Develop standardized research definitions for meals and snacks. Understand better the food landscape where foods are purchased and consumed and how the food environment effects nutritional status. Understand better the concept of dietary patterns and develop standardized methods for dietary patterns research.

The US population purchases and consumes food in a variety of locations. The diet quality is low regardless of where food is .purchased or consumed.. Rates of diet-related chronic conditions are high. Obesity, CVD, CVD risk factors, diabetes, cancer, and osteoporosis are all very common. Improving diet quality will help reduce risk of these diseases with major morbidity, mortality and health care expenditures. Research Recommendations Nutrition Surveillance, NHANES/WWEIA needs more respondents from a variety of racial/ethnic minority groups, more non-U.S. born residents and increase the number of pregnant women and older Americans - all of these groups are currently under-represented.
