healthy eating index

March is National Nutrition Month. Throughout the month, USDA will be highlighting results of our efforts to improve access to safe, healthy food for all Americans and supporting the health of our next generation.

About half of all American adults—117 million individuals—have one or more preventable chronic diseases, many of which are related to poor quality eating patterns and physical inactivity. These include cardiovascular disease, high blood pressure, type 2 diabetes, some cancers, and poor bone health. More than two-thirds of adults and nearly one-third of children and youth are overweight or obese.  Trends in food intake show that Americans are not consuming healthy eating patterns.

Earlier this year, the US Department of Health and Human Services’ Office of Disease Prevention and Health Promotion and the US Department of Agriculture’s Center for Nutrition Policy and Promotion released the 2015-2020 Dietary Guidelines for Americans. Written for use by health professionals and policy makers, the Dietary Guidelines is released every 5 years to provide nutrition guidance for Americans age 2 and older to prevent diet-related chronic disease and maintain health.

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

Have you ever heard of the Healthy Eating Index? The Healthy Eating Index (HEI) measures the quality of Americans' food choices. At USDA we use the HEI to see how closely Americans are following the Dietary Guidelines for Americans and MyPlate. The HEI assigns scores to diets on a scale in which the maximum score of 100 indicates that the diet meets all Dietary Guidelines recommendations. The HEI shows us that the diets of most Americans could use some improvement. For example, HEI scores for 2007-08 averaged about 53.5 points out of 100 points, and these scores have not changed substantially since 2001-02. Using the HEI we can also compare how food choices and overall diet quality differ among males and females and in certain age groups, such as HEI scores for children and adolescents.

The HEI includes 12 components, each of which measures one aspect of dietary quality. These components represent all of the key Dietary Guidelines food choice recommendations. Nine of the components focus on the types of foods that Americans should eat more of, such as fruits, vegetables, dairy, and whole grains. Three components focus on foods or nutrients that are over consumed and Americans should eat less of, including refined grains, sodium, and calories from solid fats and added sugars (empty calories).

Everyone wants to save money at the grocery store, especially those on a tight budget. The new Healthy Eating on a Budget section of ChooseMyPlate.gov empowers cost-conscious consumers to make healthy choices with insightful information about meal planning, smart shopping ideas, and creating healthy meals with simple ingredients.  Web-based trends indicate that consumers continue to look for information about how to make better eating decisions with limited resources. Healthy Eating on a Budget offers a step-by-step game plan to help families save money and make nutritious meals at home.

Recent scores from the USDA Healthy Eating Index indicate that Americans can struggle to meet recommendations from the Dietary Guidelines for Americans.  Most of us need to increase our intake of whole fruit, dark-green and orange vegetables, whole grains, and fat-free or low-fat dairy.  Cost is often considered a barrier to eating healthier and the new resource will help consumers overcome this perception.

Finding groceries can be difficult in many inner city neighborhoods, and in many rural areas the challenge can be even more daunting.  Americans living in remote areas might easily spend half a day just making a grocery run. And for many Native Americans living on Indian reservations, simply getting to a place to purchase nutritious foods becomes a constant struggle.

Food security is a top priority for the Agriculture Secretary Tom Vilsack. “Expanding access to nutritious food will not only empower American families to serve healthy meals to their children, but it will also help expand the demand for agricultural products.”
