Revised U.S. Dietary Guidelines Set New Lifestyle Paradigm

 

New 2005 Dietary Guidelines for Americans Present Opportunities and Challenges

UNAIDS
Obesity has risen at an epidemic rate in the United States during the past 20 years. Its challenge did not appear overnight, and its scourge will not be resolved quickly or by a singular event. Reversing its upward trend requires collaboration among government and private sectors, as well as a commitment to action by communities across the country. It also demands that each of us assume responsibility for promoting the nation’s health. One important way to do this is by implementing the new Dietary Guidelines for Americans 2005.

A Focus on Health
As a commitment to improving the health of Americans and fighting the growing obesity epidemic on a national scale, the president has launched his HealthierUS initiative, which consists of four key strategies:
1. Be physically active each day.
2. Eat a nutritious diet.
3. Get preventative screening.
4. Avoid risky behaviors.

The government’s Dietary Guidelines for Americans 2005 directly support two of these strategies while setting forth specific, science-based recommendations to help the public reach target nutrition levels, promote healthier lifestyles and reduce risk for major chronic diseases such as high blood pressure.

Taken together, the 2005 guidelines encourage most Americans to eat fewer calories, make wiser food choices and be more active. This is especially important because poor diet and a sedentary lifestyle are related to the major causes of morbidity and mortality in the United States, including cardiovascular disease, type 2 diabetes, hypertension, osteoporosis and certain cancers; unhealthy diets and physical inactivity are also the main factors contributing to the nationwide increase in overweight and obesity.

The Recommendations
Jointly published by the U.S. Departments of Agriculture (USDA) and Health and Human Services (HHS) every five years since their debut in 1980, the Dietary Guidelines for Americans target healthy people over the age of 2 who are living in the United States. With such focus areas as “Adequate Nutrients Within Calorie Needs,” “Food Groups to Encourage,” “Carbohydrates” and “Weight Management,” the 2005 directives emphasize making choices that promote the increased consumption of vegetables, fruit, low-fat milk products and whole grains, as well as regular physical activity. They also highlight limiting intake of saturated and trans fats, added sugars and salt, and alcohol, and, to a much greater extent than their predecessor document in 2000, underscore balancing caloric intake with energy needs, with reference to recommended eating patterns such as the USDA Food Guide and the Dietary Approaches to Stop Hypertension (DASH) Eating Plan (http://www.nhlbi.nih.gov/health/public/heart/hbp/dash/new_dash.pdf). Additionally, they emphasize keeping food safe, with steps to avoid microbial foodborne illness. (See chart at end of article.)

The nine inter-related sections of the 2005 dietary guidelines offer 23 mutually dependent key recommendations in place of the 10 more general guidelines presented in the 2000 directives. This year’s document also provides additional advice for specific population groups such as pregnant and breastfeeding women, overweight individuals, children and adolescents, and older adults. All recommendations incorporate current scientific knowledge and findings, since an important component of the 2005 guidelines is a comprehensive report on new scientific information developed by the Dietary Guidelines Advisory Committee (http://www.health.gov/dietaryguidelines/dga2005/report/).

The Dietary Guidelines for Americans 2005 also differ from their predecessor in that the official guidelines publication is targeted to policymakers, healthcare providers, nutritionists and nutrition educators rather than to the general public. A separate consumer publication called Finding Your Way to a Healthier You: Based on the Dietary Guidelines for Americans provides practical advice in non-technical language (http://www.healthierus.gov/dietaryguidelines).

Implementing Dietary Guidance
Because of their focus on health promotion and risk reduction, the Dietary Guidelines for Americans affect government nutrition programs, including those focused on research, education, school lunch, food assistance, labeling and nutrition information. The guidelines also serve as a policy document from which consistent government programs, policies and messages in education related to nutrition and health are developed. An interagency working group reviews all public nutrition education materials developed by federal agencies to ensure that the information is in harmony with the guidelines.

USDA uses the dietary guidelines for policy development in food assistance initiatives such as the Child Nutrition Programs, which include school lunch, and the Elderly Nutrition Program. The agency also uses the guidelines as the basis for the development of its food guidance system and related educational tools such as the new food guide pyramid, www.MyPyramid.gov, a Web site offering individualized advice on the types and amounts of foods that Americans should eat for good health, based on their needs.

As the Food and Drug Administration reviews future regulations to improve the appearance and content of nutrition labels to help consumers make better-informed decisions, it too will consider the information outlined in the Dietary Guidelines for Americans.

Partnerships and Action
As the government develops educational materials and communicates science-based information to Americans, it relies on traditional partnerships with extension nutritionists and public health educators, as well as new partnerships with other health professionals and the private sector. Such cooperation is essential to increase the level of resources devoted to consistent, multichannel strategies to promote the Dietary Guidelines for Americans and the Food Guidance System in order to better influence eating and physical activity behaviors.

Meanwhile, as scientific research provides clear evidence of the relationships between dietary components and health benefits, the challenge for the food industry becomes even greater. New product development can address consumer needs for healthier diets and promote behavior change in how and what Americans eat, helping to keep chronic diseases at bay. One such example involves a large Midwest-based company that strategically shifted one of its product categories to incorporate whole grains, a food component that the dietary guidelines encourage Americans to include daily in their diets. This change alone is estimated to increase whole grain servings by 26 million per day. Another example is an East Coast-based convenient-food company that eliminated trans fatty acids from its snack product line, prompting the removal of an estimated 55 million pounds of trans fatty acids from the food supply. Such changes in the marketplace can provide consumers with more healthful choices and arm them with the tools necessary to implement the guidelines.

Developing actionable and attainable behavior-change messages is another important aspect to impacting the health of Americans. As mentioned above, this year, USDA and HHS published Finding Your Way to a Healthier You, a consumer brochure that accompanies the guidelines policy document, with tested messages for consumers to follow the Dietary Guidelines for Americans 2005.

Food industry and health professionals can also help consumers translate the guidelines into practical, easy-to-understand messages for eating well and staying healthy. To this end, the USDA is supporting HHS efforts to develop educational materials, such as a toolkit for health professionals, and to provide nutritionists and dietitians with resources, including PowerPoint slide presentations that can be used for teaching consumers how to incorporate the dietary guidelines into their everyday lives. Meanwhile, www.MyPyramid.gov translates science into individualized information that the consumer can use directly and immediately to put the guidelines into action, thus helping to move the guidelines’ health-promoting suggestions from the sidelines to the front lines.
