Dietary Guidelines for Americans

The Dietary Guidelines for Americans provide advice on the foods and beverages that will help individuals develop a healthy diet, meet nutrition needs and prevent diet-related diseases. The guidelines also set the standards for federal feeding programs, such as the school breakfast and lunch programs, and nutrition education messages.

The U.S. Departments of Agriculture and Health and Human Services are required to review and update the guidelines every five years. The process for the 2020-2025 guidelines is underway, and the departments are relying on recommendations from nutrition and health experts who serve on the Dietary Guidelines Advisory Committee (link to section below), as well comments from the public, to help shape the final guidelines.  

Our Position

The current guidelines (2015-2020) affirm the unrivaled contribution made by dairy foods and remind Americans that a healthy diet includes three daily servings of low-fat and fat-free dairy. IDFA has urged the committee to maintain the number of servings and expand choices to include higher fat levels.  

IDFA also stressed the importance of keeping dairy as a separate and essential food group and asked the committee to consider nutrient density when assessing dairy products with added sugars. In addition, IDFA has called for research on feeding yogurt to infants starting at 6 months of age, which would align with other USDA program regulations.

Dairy Detractors

The committee also is hearing from individuals and groups who want recommendations for plant-based diets with little to no dairy included in the guidelines. They cite concerns with animal welfare, sustainability and the environment, among other issues, but their comments aren’t based in science. IDFA will continue to share the large and growing body of scientific evidence that shows dairy foods offer unparalleled health and nutrition benefits to people of all ages.

“Dairy products play an important role in the diet of children… In fact, milk is the leading food source of three of the four nutrients of public health concern (calcium, vitamin D and potassium) in the diet of American children 2-18 years.”

Dietary Guidelines Advisory Committee

Barbara Schneeman, Ph.D., is the chair the 2020 Dietary Guidelines Advisory Committee, and Ron Kleinman, M.D., is vice chair. Schneeman is a professor emerita at the University of California-Davis in the food science, technology and nutrition unit. Kleinman heads the department of pediatrics at Massachusetts General Hospital and is a professor of pediatrics at Harvard Medical School. Read more for a full list of committee members. 

USDA hosts two department websites, and, to make it easy for the public to follow the committee’s work.


The process for developing the 2020-2025 Dietary Guidelines for Americans is underway. Most of 2019 was devoted to collecting public comments as the advisory committee began gathering and reviewing extensive scientific literature. IDFA presented oral comments at the DGAC committee meeting in January, which you can view here. IDFA also submitted written comments—please review the comments here—with a focus on keeping three daily servings of dairy and a separate dairy category in recommended eating patterns.
